AIX-Definitions

Definitions
Examples What it means
PHYSICAL PARTITION (PP) Smallest unit a PV is divided into (4 MB partition size)
LOGICAL PARITITION (LP) One or more PPs. LP represents a mirrored copy of a PP. Up to two copies of a PP can be mirrored resulting in a LP count of three (2 mirrors plus original).
LOGICAL VOLUME (LV) One or more PPs. A file system resides on top of an LV. Only one LV is mapped to a file system. A LV can't span across a VG. Up to 255 LVs in a VG
VOLUME GROUP (VG) One or more PVs. A collection of PVs that users view as a single oversized PV. A VG can consist of any mixture of physical disk types (size=320,355,400,670,800,857 MB), though performance is most consistent if devices of the same size are used in a single VG. Up to 32 VGs per system.
PHYSICAL VOLUME (PV) One or more LVs. Represents a hard disk (hdisk0).
AREA (VGDA) Information about all the LVs and PVs within a VG. First 64K of a PV is reserved for this area - defined in . The VGDA consists of
• BOOTRECORD: - first 512 bytes. Allows the Read Only System (ROS) to boot system
• BAD BLK DIRECTORY - found in
• LVM RECORD - found in
AREA (VGSA) Informations about which PPs are stale and which PVs are missing within a VG. The LVM and SCSI driver reserves somewhere between 7-10% of the available disk space for LVM maps, etc.
Logical Volume Set-up
All system LVs (hd1..hd8, hd9var) should reside in the VG named rootvg, under one PV if possible. This will allow complete re-installation of the system from your 'mksysb' tape without affecting the application data that resides on your other VGs.
There is no difference in response time between a single or multiple VGs. When an LV is accessed
• The ODM database (/etc/objrepos/*) is searched to determine which VG the LV belongs to.
• Then the VGDA for that VG is read to determine the physical placement of the LV on that PV and ultimately the physical track and sector where the data resides.
A few notes about Mirroring
Mirrored LVs that generate lots of write I/O calls, will cause a disk performance penalty (such as paging LVs). For LVs that encounter heavy read I/O calls, disk performance is increased. Since the LVM (logical volume manager) driver keeps track of the location of each disk head, the disk arm closest to the data being requested will be issued the read request. Further, mirroring can only be performed within a single VG. NFS mounted file systems cannot be mirrored.

Steps required to re-import VG's after a system re-install
When a system is re-installed, the disk drives may not be named in the same order as they originally appeared. If the system halts with the message 'performing Auto varyon of Volume Groups' on the console, perform these steps:
1. Press CTRL-C to continue and login as root
2. Export ALL non-root volume groups export
3. Shutdown and reboot the system shutdown -Fr
4. Re-import non-root volume groups importvg -y
top of page

Steps required to replace a failing PV from a non-root VG
1. Backup all filesystems found on the failing PV.
2. lspv -l (lspv -l hdisk2) To determine which filesystem(s) are found on the PV in question.
3. Find out how the LVs are laid-out on the PV so you will know how to re-create them when the time comes.
4. lslv -m (lslv -m oracle) You will use the output of the lslv command to serve as a template for creating a map file for this LV later on.
5. Unmount all filesystems on that PV. umount to unmount each filesystem from the PV in question.
6. Remove all LVs found on that PV. rmlv (rmlv /oracle)
7. Remove the questionable PV from the system. reducevg
8. Remove the PV entry from the ODM database. rmdev -l -d (rmdev -l hdisk2 -d)
9. Shutdown the system: Shutdown -F
10. Remove the bad PV and install the new PV
11. Add the new PV to the VG in question. extendvg (eg., extendvg datavg hdisk2)
12. Re-create the LVs removed from the OLD PV to the NEW PV.
mklv -y -m (mklv -y oracle -m oracle.map oraclevg 200 hdisk2)
The map file is assembled from the output generated from the lslv -m command in step 2 above. Do this for each LV that existed on the removed PV.
13. Re-size the filesystems on the new PV. mkfs /dev/ (mkfs /dev/oracle) Do this for each file system that existed on the removed PV.
14. Perform a filesystem check before mounting it. fsck -f /dev/ (fsck -f /dev/oracle)
15. Mount all filesystems on that PV. mount (mount /oracle)
16. Now restore the data you backed up

How to move a PV to another SCSI controller
As long as all your doing is moving a PV to another SCSI adapter and not placing that PV in another VG, then just move the PV to the other SCSI adapter and reboot. When the machine comes back up and finds that the disk is no longer located in its previous slot, it finds the exact PVID of the disk on the other adapter and assumes the disk was moved. It then changes the ODM accordingly, and your back in business again.

How to mirror a boot logical volume
Each hard drive is a potential boot device. The bosboot command creates a bootable image in the BLV (boot logical volume), which is used to boot AIX. The first block (sector) on the disk is called the boot block or IPL record. In addition, NVRAM contains a list of boot devices which can be specified by the bootlist command. The boot device can be changed by using the bosboot and bootlist commands. The format for these commands follows:
bootlist -m normal hdisk0 for normal operations
bootlist -m service fd0 rmt0 hdisk0 for service operations
bosboot -u -d /dev/hdisk0 bootable image in BLV on hdisk0
The bosboot command puts a bootable image in the BLV that is used to boot the system. Also, the bosboot command puts the physical sector number of the beginning ofthe bootable image on this disk, into the boot block of the disk. Since only one PSN (that of the primary copy of the BLV) is stored, therefore all copies of the BLV must reside on the SAME physical partitions of their respective devices.
An example of a mirrored BLV with 3 copies follows:
blk XXX, where XXX is the starting physical sector number in hex, within the specified physical partition (PP) number.
Copy 1 Copy 2 Copy 3
hdisk0 hdisk1 hdisk2
LP 1: PP 1(blk 200 ) LP 1: PP 6(blk C200) LP 1: PP 4(blk 8200)
LP 2: pp 2(blk 2200) LP 2: PP 7(blk E200) LP 2: PP 5(blk A200)
To use hdisk0 as the boot device, specify the following: bosboot -a -u -d /dev/hdisk0
The IPL record on hdisk0 indicates the boot image starts at PSN (physical sector number) 200. Now, the system can be booted using drive hdisk0.
To use hdisk1 as the boot device, issue the following: bosboot -a -u -d /dev/hdisk1
Because the bosboot program only looks for the PSN of the first copy, the IPL record indicates the starting PSN for the boot image as 200 instead of the correct C200. Attempts to boot with hdisk1 as the boot device will fail.
To mirror the BLV and get around this problem, do the following. Insure that all the copies occupy the same physical partitions on each device. It is not important which partitions the BLV uses, but all copies must use the same relative positions on the disk device. So, the configuration should be:
Copy 1 Copy 2 Copy 3
hdisk0 hdisk1 hdisk2
LP 1: PP 10(blk 20200) LP 1: PP 10(blk 20200) LP 1: PP 10(blk 20200)
LP 2: pp 11(blk 22200) LP 2: PP 11(blk 22200) LP 2: PP 11(blk 22200)
To move individual partitions around and keep them in sync, use the lmigratepp command.
To find available physical partitions on a disk, use lspv -m hdisk? Take the output of this command and choose two physical partition that are allocated/free on all the target disks and use these partitions to create your BLV image on multiple disk drives.
If your mirroring, make sure that PTF U407433 is installed. This allows you to disable the QUORUM feature. When one disk dies, the other disk will take over without checking to see if the quorum is still meet. (chvg -Qn rootvg)
When a write is performed to a disk containing mirrored copies, all copies are written simultaneously in parallel mode, and each is written sequentially in sequential mode.
Should the system crash while parallel writes are being performed to mirrored copies of the data, inconsistencies may exist between the data which was actually written to the different copies. To protect against this, the Mirror Write Consistency Cache was developed to write a record to the disk each time a mirrored write is in progress, so that when the system is rebooted, a record will show that possible inconsistencies may exist, and the data from the first physical partition is rewritten to all other physical partition copies. However, by enabling the Write Consistency Check, the penalty you pay is having to do an extra read/write when doing I/O. When this feature is disabled, if the system goes down because of power failure or system crash, you will need to MANUALLY perform a syncvg when the system is rebooted.
The jfslog is used to keep a record of file system metadata (superblock, inode, directories, etc) and also ensures the integrity of the file system.
The impact of losing the PV containing the jfs log will be quite serious. All file systems using that log will become unavailable.

bootinfo
Examples What it does
/usr/sbin/bootinfo -b Displays the boot PV device (hdisk0). The boot PV does NOT always refer to hdisk0. The boot PV will ALWAYS be the PV that contains the LV named hd5. The LV hd5 contains the boot logical volume (BLV), which contains the information needed to boot the system into a single/multi-user state
bootinfo -a hdisk1 320 4 8 00-01-00-00
top of page

chlv
Changes the attributes for an LV
Examples What it does
chlv -x 256 hd1 When creating large LVs or extending an existing LV to over 512 MB (assuming PP SIZE=4) in size, the following error message will be displayed: 516-787 extendlv: Maximum allocation for logical volume h1 is 128. To resolve this problem, perform the above command where 256 represents the MAXIMUM number of logical partitions that can be allocated for that LV. This command can be executed while the file system (residing on top of the LV) is mounted.
chlv -n informixlv lv00 Changes the name of LV from lv00 to informixlv. If there is a filesystem mounted on top of that LV, the file system must be unmounted and the LV must be in a closed state for this command to work.
chlv -n
top of page

cplv
Copy the contents from one LV to a new or existing LV
Examples What it does
cplv -e newroot hd4 Copies the LV hd4 to an LV named newroot. If newroot doesn't exist, it will be created. If newroot is smaller than hd4, the extra PPs from hd4 won't be copied to the desintation LV newroot
top of page

chpv
Change the characteristics of a physical volume
Examples What it does
chpv -a n hdisk2 Prohibits the allocation of additional PPs on PV hdisk2
chpv -vr hdisk2 Temporarily removes a PV from a VG (normally used for maintenance) This command removes the VGDA and VGSA copies from the PV, thereby affecting the number of copies required for a quorum.
chpv -va hdisk2 Returns an inactive PV back to the VG
top of page

chvg
Examples What it does
chvg -Qn rootvg This will turn quorum checking off (default is on). Afterwords, the volume group must be varied off and back on again to cause the change to take effect. In the case of rootvg, this means a reboot.
top of page

exportvg
Used to export a VG from one system so that it can be imported by another. This command will erase all data referencing the VG being exported from the ODM database, but won't remove this information from the VGDA (undefines the VG on the system). The information deleted from the ODM but not the VGDA is the LV and VG entries.
To manually transport a VG between systems, the normal process is to varyoff and export the volume group on System A:
varyoffvg VG
exportvg VG
Then move the drives to System B followed by importing them and finally varying them on:
importvg -y VG PV
varyonvg VG
exportvg vg2
importvg -y vg2 hdisk1 #hdisk1 is PV that belongs to VG named vg2
varyonvg vg2
The above steps can be used to correct the ODM when it is not in sync with the VGDA
top of page

extendvg
Add a new physical drive to a volume group
Examples What it does
extendvg datavg hdisk3 Adds the PV hdisk3 to VG datavg. This increases the size of the VG by adding one or more PVs.
top of page

getlvodm
Examples What it does
getlvodm -u rootvg Will determine whether the ODM or VGDA has the correct copy of the VGDA. If the above command returns the character 'y' for the VG specified, then the ODM database is correct and the VGDA is out-of-sync. To correct the situation when the VGDA doesn't have a good copy, perform the following steps:
1. importvg -y vg2 -f hdisk1 use force option
2. varyonvg -f vg2 use force option
3. copy data off drive
4. reducevg vg2 hdisk1
5. rmdev -l hdisk1 -d
6. cfgmgr
7. extendvg vg2 hdisk1
8. add file systems
9. restore data previously backed off to tape
top of page

importvg
Used to import a VG from a system that exported it. This command will restore the ODM database from information read from the VGDA. When a VG is imported, /etc/filesystems will be updated with any entry points needed for those LV's and mount points not currently defined.

ipl_varyon
Examples What it does
ipl_varyon -i Indicates which PV is your BOOT drive
top of page

lqueryvg
Examples What it does

lqueryvg -p hdisk0 -L List all the LV ids/names in the VG where PV hdisk0 resides
lqueryvg -p hdisk3 -P Lists all the PV ids that reside in the VG where hdisk3 resides
top of page

lslv
List characteristics about a logical volume
Examples What it does
lslv hd3 Display attributes of the LV hd3
lslv -l hd3 List distribution of where LV hd3 resides on PV hdisk1
lslv -m hd3 List distribution of PPs where LV hd3 resides on PV hdisk1
• MAX Lps: If LV created is larger than 512 MB (128 * 4), then this field needs to be upped by the following formula: (LV size in megabytes) / PP size = MAX LP count 900 MB / 4 = 225 The command to change the LP count to 225 for an LV named pick is: chlv -x 225 pick
• COPIES:
o value is 1= original copy
o value is 2= first mirrored copy
o value is 3 = second mirrored copy
• STALE PPs: If COPIES > 1 and STALE PPs > 0, means that a mirrored LP is not available or current with other LPs.
• INTER-POLICY:
o If set to MIN, an LV will only reside on 1 drive
o If set to MAX, an LV can span multiple LVs. Distributes an LV among more than 1 PV.
• INTRA-POLICY: Has 3 values (edge, middle, center). When an LV is created, it will be assigned 1 of the 3 allocation strategies listed above.
• EFFICENCY: Represents the efficency with which PPs are allocated based on the 3 possible states of the intra-policy.
• RELOCATABLE : If yes, then the 'reorgvg' command is allowed to move the LV to a new position on the current PV or be placed on another PV.
• SCHEDULING POLICY: If set to PARALLEL, insures writes to mirrored copies are performed to seperate PVs in parallel.
• WRITE-VERIFY: If set to NO, will not perform a follow-up read to each write for verification.
• MIRROR WRITE CONSISTENCY: When enabled, suffer a 20% performance penality. Use the syncvg -v command to resync disk drives in a VG that loses a PV.

lsps
List characteristics of paging space(s).
PAGING SPACE LOW messages will be generated when 512 pages remain free in the pool of free pages. Processes will be terminated when only 128 pages of free memory are left.
AIX determines which users have the most page space allocated to them and selects those processes for termination. All real memory allocated to a process will have a backing store of equal size (for every page of real memory allocated, there will be a page of disk space from paging space allocated)
Its recommended that the first paging space (/dev/hd6) be larger, since this one is brought on sooner than the rest, resulting in being more full than the others.
Thrashing should not be confused with the problem of low paging space. Low paging space is the condition in which the amount of paging space is insufficient. Thrashing is the condition in which the amount of RAM is insufficient. Low paging space involves the consumption of disk space; thrashing involves the consumption of RAM and disk I/O.
Example: lsps -a (Display attributes of all paging spaces)
LV hd6 is the default paging space. If more than one paging LV is defined, hd6 will always have a higher percentage of utilization since this is the first paging LV turned on at boot time. Once all the other paging LVs have been swapped on, paging is allocated on a round robin basis - four pages (pagesize is 4k ) at a time.
80% (MAXPERM) of real memory is to be used by persistent storage. Persistent storage is information that is not paged to the page space (/dev/hd6) but rather is paged to the physical volume where that file resides.
top of page

lspv
List charactertistics of a physical volume
Examples What it does
lspv hdisk0 Stale partitions refers to mirroring. If the PV has no mirrored LPs, then the value for this field is zero.
lspv -l hdisk0 Display distribution of what LVs reside on the PV named hdisk0
lspv -p hdisk0 Display distribution of PPs for each LV that resides on the PV named hdisk0
top of page

lsvg
List characteristics about volume groups
Examples What it does
lsvg rootvg Display attributes for VG rootvg
lsvg -p rootvg Display PV distribution about VG rootvg
lsvg -o Lists all active VGs in the system
top of page

migratepv
Moves one or more LVs to one or more PVs. If '/dev/hd5' is moved to another drive, a spcial step is required, else the system will not boot the next time it's rebooted.
Examples What it does
migratepv hdisk0 hdisk1 Moves all LVs from hdisk0 to hdisk1
migratepv -l hd1 hdisk2 hdisk1 Copies all PPs for LV hd1 from hdisk2 and places them on a PV named hdisk1
top of page

mklv
Creates a logical volume on a physical volume
Examples What it does
1) mklv -y hd7 -t sysdump -a e rootvg 2 hdisk0
2) sysdumpdev -P -p /dev/hd7 The first command will create a LV dump device named hd7 that consists of 2 PPs located on the edge of PV hdisk0. The second command will assign the system dump device to LV /dev/hd7.
1) mklv -y hd5 -t boot -a e rootvg 2 hdisk2
OR
1) migratepv -l hd5 hdisk0 hdisk2
2) bosboot -a -l /dev/hd5 -d /dev/hdisk2
3) bootlist -m normal hdisk2 Creates and updates a new boot logical volume (hd5) on PV hdisk1. When you move the /blv (boot) file system, you MUST change the disk from which the system tries to boot from to NORMAL mode.
top of page

mklvcopy
Makes a mirrored copy of an LV. Note that this command will allocate PPs for the next copy, but the data within is not updated. This must be performed by the syncvg command.
Examples What it does
1) mklvcopy hd1 2 hdisk1
2) mklvcopy hd2 2 hdisk1
3) mklvcopy hd3 2 hdisk1
4) mklvcopy hd4 2 hdisk1
5) mklvcopy hd5 2 hdisk1
6) mklvcopy hd6 2 hdisk1
7) mklvcopy hd7 2 hdisk1
8) mklvcopy hd8 2 hdisk1
9) syncvg -v rootvg Will mirror the operating system so that the system may be booted from either disk in the case of a disk drive failure. The syncvg command will insure that all LVs just copied will be in synchronized with each other.
• The third parameter ('2') means make a copy of the original LV (hd?) on the PV named hdisk1.
• If the third parameter was a '3', then each LV would have 3 copies total - 2 mirrored copies and the original.
1) mklvcopy -m lv00.map lv00 2
2) syncvg -l lv00 When creating the LV named lv00, use the map file named lv00.map. Using the syncvg command will update the mirror copy.
top of page

putlvodm
Reads LV data from the command line and writes it to appropriate ODM (Object Data Manager) class fields.
Examples What it does
putlvodm -K `getlvodm -v rootvg` Unlocks a VG so that the LVM commands can access or change information about a particular LVM device.

If the message 0516-366 lsvg: Volume group rootvg is locked is ever seen, the above command will unlock the VG in question.
top of page

redefinevg
Determines which PVs belong to the specified VG and re-enters this information into the ODM. This command is typically used to fix inconsistencies in the ODM database by reading a copy of the VGDA and recreating the ODM entries as needed.
Examples What it does
redefinevg -d hdisk0 rootvg Updates the ODM for a specific VG with the information stored in the VGDA
top of page

reducevg
Removes one or more PVs from a VG
Examples What it does
reducevg rootvg hdisk1 Removes the PV hdisk1 from the VG rootvg.
reducevg -df rootvg hdisk2 Removes hdisk2 from the VG rootvg and all LVs on that PV that weren't previously removed.
top of page

restbase
Reads the base customized information from the boot image and restores it in the ODM
top of page

rmlv
Removes a logical volume from a volume group
Examples What it does
rmlv lv00 Removes the LV lv00 from a VG and restores that space back to the free DASD list. The amount of free disk space returned can be verified by executing the lsvg rootvg command before the rmlv command is executed and after it.
• If there is a file system associated with the LV to be deleted, it first must be unmounted.
• Further, the references to that file system will not be removed from the /etc/filesystems. The rule when removing a file system is to first umount the file system and then use the 'rmfs' command to remove all references of this file system and it's associated LV.
top of page

rmlvcopy
Removes logical partition (mirrored) copies. If no PV named is included with this command, the last copy created will be removed first.
Examples What it does
rmlvcopy lv00 2 Removes both copies of the LV lv00
rmlvcopy lv00 1 hdisk2 Only the copy (LV:lv00) that exists on PV hdisk2 is removed.
top of page

savebase
Reads the base customized information from the ODM and restores it to the boot device (hd5).
top of page

schedtune
A memory load algorithm that detects when the system is thrashing and suspends active processes and delays the initiation of new processes for a period of time. Since the suspended processes are not scheduled, their pages in RAM are not being referenced, and are freed for other processes to use.
When thrashing stops, the suspended processes are gradually activated again. The result is that the performance is much more predictable and constant when RAM is in demand. Schedtune is part of the lpp named 'bosadt.lib.obj' or PTF U412059. AIX does't allocate a page until you actually attempt to use it.
Examples What it does
schedtune -h 0 Disables memory load control. Memory load control is ENABLED by default.
schedtune Determine current settings for load control.
schedtune -D Resets memory load control to its default characteristics
top of page

syncvg
Synchronizes stale partitions within VG. syncvg is automatically run when the VG is varied on ('varyonvg' command).
Examples What it does
syncvg -v rootvg Synchronizes stale partitions on any PV that belongs to VG rootvg.
syncvg -l lv00 Synchronizes the LV lv00 so that all copies are identical
top of page

synclvodm
Will read the VGDA from the PV specified and update the ODM database. This command is typically used to fix inconsistencies in the ODM database, by reading a copy of the VGDA and recreating the ODM entries as needed.
Examples What it does
synclvodm rootvg hd1 Rebuilds the ODM database for a LV hd1, by reading the VGDA.
top of page

sysdumpdev
Operations performed on the system dump device
Examples What it does
sysdumpdev -p sysdumpnull Turns off the dump device
sysdumpdev -p hd7 Reactives the dump device
updatevg rootvg Resynchronizes the VG information in the ODM
top of page

varyoffvg
Takes off-line a VG and all associated file systems and LV's. If a file system or LV is still mounted or open when this command is executed, the command will fail. A VG that has an active paging LV cannot be varied off or exported.
Use the chps -an to disable the paging LV followed by rebooting the system.
Must umount all file systems on each PV that belongs to a VG before it can be varyed-off
Examples What it does
1) umount /oracle
2) varyoffvg oracle Varys-off ALL PVs associated with the VG named oracle. Essentially makes that VG inaccessible
top of page

varyonvg
Activates a VG. Takes the information stored in the ODM database and updates the kernel.
Examples What it does
varyonvg oracle Activates the VG named oracle and makes accessible any LV and/or file system that belongs in that VG
varyonvg -m1 oracle Will insure the ODM database matches the attributes stored in the VGDA (syncs VGDA to ODM) and reports the status of all PVs.
varyonvg -f oracle Used if the VG attempting to be varied on was not properly exported from another system, due to a system crash or some similiar instance. This force option is only needed when there is a problem with the VGDA on the imported VG

The volume is appsvg01 group, the logical volume is lapps0101, the point of assembly / apps / websphere, the block size is 4096 and it is accessible mode read / write (-p 'rw'), with automatic mounting reboot (option A-y).
# mklv it lapps0101 Does jfs2 appsvg01 1
lapps0101
# CRFs jfs2-v-d lapps0101-m / apps / websphere A-y-p 'rw'-a agblksize ='4096 '
File system created successfully.
65,328 kilobytes total disk space.
New File System size is 131,072
# mount / apps / websphere
We can then cutting the right size with:
CHFS-a size = 4G / apps / websphere
Same procedure for a filesystem jfs:
# mklv-y-t lsystsy0111 jfs vsystsy01 1 lsystsy0111 A-y-p 'rw'-a agblksize ='4096 '
Based on the parameters chosen, the new / root / JFS file system test
is limited to a maximum size of 134,217,728 (512 byte blocks)

New File System size is 65,536
# mount / root / test
# CHFS-a size = 3G / root / test

12.16. know how the size and fragmentation of a file?
Use the fileplace:
fileplace smit.log

File: smit.log Size: 6165 bytes Vol: / dev/hd4
Blk Size: 4096 Frag Size: 4096 Nfrags: 2 Compress: no

Logical Fragment
----------------
0006496 1 Frags 4096 Bytes, 50.0%
0006509 1 Frags 4096 Bytes, 50.0%

• create the volume group named datavg. The-f force the creation because the disk hdisk1 had an ID or pvid (00ccd2cd26257aa4).
• mkvg-s 128-f-y datavg hdisk1
• datavg
The size of a PP was set to 128 MB could put a small value, but we must take into account the size of the disc. By putting 1MB would be this:
mkvg # 1-s-f-y datavg hdisk1
0516-1208 mkvg: Warning, The Physical Partition Size of 1 requires the
creation of 70,006 partitions for hdisk1. The system limitation is 16,256
physical partitions per disk at a factor value of 16. Specify a larger
Physical partition size or a larger factor value in order create a
volume group on this disk.
0516-862 mkvg: Unable to create volume group.
An interesting option is mkvg of option-B to create Big volume.
• We check the vg

16.1. How to use the sticky-bit?
Normally (without 't') anyone who says that the permission to a list of addresses can delete any files in the address list regardless of who owns, even though he can not read or write to the file.
With 't' set, only the owner of a file can be deleted.
1. chmod + t directory to set the sticky-bit
2. chmod does anul directory for the sticky-bit

16.2. how to read the acl of a file or directory?

aclget-o memo.txt REP

16.4. how to fix the acl a file or directory?
aclput-i memo.txt file

16.5. What do the leaves extended?
Expanded permissions allow the owner of a file to define access to that file more precisely. The leaves change permissions Expanded basic file (the owner, group, others) by allowing, deleting, or specifying access modes for specific individuals, groups or combinations of group and user . The leaves are modified by using keywords.
keywords permit, deny, and specify defined like this:
1. permissions granted to the user or group access to the file specified
2. deny prevents the user or group to use access to the file indicated
3. specify precisely defines access to the file to the user or group

22.7. LED status code du dump
c0 The dump completed successfully. Go to Copying a System Dump.
0c1 An I/O error occurred during the dump. Go to System Dump Facility.
0c2 A user-requested dump is not finished. Wait at least 1 minute for the dump to complete and for the operator panel display value to change. If the operator panel display value changes, find the new value on this list. If the value does not change, then the dump did not complete due to an unexpected error.
0c4 The dump ran out of space . A partial dump was written to the dump device, but there is not enough space on the dump device to contain the entire dump. To prevent this problem from occurring again, you must increase the size of your dump media. Go to Increase the Size of a Dump Device.
0c5 The dump failed due to an internal error.
0c7 A network dump is in progress, and the host is waiting for the server to respond. The value in the operator panel display should alternate between 0c7 and 0c2 or 0c9. If the value does not change, then the dump did not complete due to an unexpected error.
0c8 The dump device has been disabled. The current system configuration does not designate a device for the requested dump. Enter the sysdumpdev command to configure the dump device.
0c9 A dump started by the system did not complete. Wait at least 1 minute for the dump to complete and for the operator panel display value to change. If the operator panel display value changes, find the new value on the list. If the value does not change, then the dump did not complete due to an unexpected error.
0cc An error occured dumping to the primary device; the dump has switched over to the secondary device. Wait at least 1 minute for the dump to complete and for the three-digit display value to change. If the three-digit display value changes, find the new value on this list. If the value does not change, then the dump did not complete due to an unexpected error.
c20 The kernel debugger exited without a request for a system dump. Enter the quit dump subcommand. Read the new three-digit value from the LED display.
