HMC

To turn off Attention LEDs in p servers:

01. List the managed servers from HMC

  lssyscfg -r sys -F name 

02.Check the LED status

   lsled -r sa -t phys -m 

03. Change the LED status to off

  chled -r sa -t phys -m  -o off

04. Check the status again

  lsled -r sa -t phys -m 

Should see output, "state=off."

Console Using HMC Command Line

---

vtmenu
vtmenu is a Perl script which displays a list of partitions, opening a virtual terminal on the one selected. If more than one managed systems exists, a list of them is displayed first. After a managed system is selected, a list of all logical partitions on that managed system is displayed. The vtmenu command does not accept any flags or parameters and ignores all that are specified.

Escape sequence to leave vtmenu terminal session is:

    ~. 

mkvterm: mkvterm opens a virtual terminal session for an AIX, Linux, or virtual I/O server partition

To open a console terminal:

  $ mkvterm -m  -p  

This can be exited with ~~.

To remove a terminal someone else is using:

 $ rmvterm -m  -p  

On integrated Virtual machine manager (blades)

 $ mkvt -id 
 $ rmvt -id 

Manage LPARs

To list all the lpars

 lssyscfg -r lpar -m  

To list only the lpar_name, state, lpar_id, update

 lssyscfg -r lpar -m   -F name,lpar_id,state

To query the state of a particular LPAR

 lssyscfg -r lpar -m  --filter lpar_names= -F state

Note:- valid filter names are: lpar_ids, lpar_names, profile_names, work_groups

To query the profile of an LPAR

 lsyscfg -r prof -m  --filter lpar_names= 
 name=testvio100,lpar_name=testvio100,lpar_id=2,os_type=aixlinux,all_resources=0,mem_mode=ded,min_mem=256,desired_mem=32768,max_mem=32768,
 proc_mode=shared,min_proc_units=0.10,desired_proc_units=0.40,max_proc_units=4.00,min_procs=1,desired_procs=4,max_procs=4,sharing_mode=uncap,
 uncap_weight=128,io_slots=none,lpar_io_pool_ids=none,max_virtual_slots=10,"virtual_serial_adapters=0/server/1/any//any/1,1/server/1/any//any/1",
 virtual_scsi_adapters=2/client/1/10-6656A/13/1,virtual_eth_adapters=4/0/64//0/0,boot_mode=norm,conn_monitoring=0,auto_start=1,power_ctrl_lpar_ids=none,
 lhea_logical_ports=none,lhea_capabilities=none,lpar_proc_compat_mode=default,virtual_fc_adapters=none

To create LPAR

 "mksyscfg -r lpar -m $MANAGED_SYSTEM -i name=$LPARNAME,profile_name=default,lpar_env=aixlinux,shared_proc_pool_util_auth=1,min_mem=2048,desired_mem=4096,max_mem=8192,proc_mode=shared,
 min_proc_units=0.1,desired_proc_units=0.1,max_proc_units=4.0,min_procs=1,desired_procs=1,max_procs=4,sharing_mode=uncap,uncap_weight=128,boot_mode=norm,shared_proc_pool_util_auth=1"

To remove an LPAR

 rmsyscfg -r lpar -m $MANAGED_SYSTEM -n $LPARNAME

To shutdown an LPAR

 lssyscfg -r sys -F name
 chsysstate -r lpar -m $MANAGED_SYSTEM -n $LPARNAME -o shutdown --immed

To power on

 chsysstate -r lpar -m $managed_system -n lparname -o on

Upgrade HMC using Network Images

Pre steps: Login to HMC and take backup of Critical Console Data and upgrade data first. Taking backup critical console data may take few hours. Hence, prepare to wait.

Follow these basic steps.

01. Download the appropriate HMC V7 network images and put them on an FTP server.

02. Verify that the following files have been downloaded:

 initrd.gz, bzImage, disk1.img, disk2.img, and disk3.img

03. On the HMC, you must first save upgrade data by running the following commands:

   3a. To save data to both DVD and disk:
        mount /media/cdrom
        saveupgdata -r diskdvd
   3b. To save to disk alone:
        saveupgdata -r disk

04. Next, copy the files over to the bootable disk partition on the HMC from FTP server

    4a. getupgfiles -h remote_hostname  -u  --passwd  -d  
    Note: use -s to use sftp instead of ftp.
    4b. If you want to see the progress of copy process, run the following command
    while true; do ls -la /hmcdump; sleep 30; done

05. After the files are copied over, run the following command:

    chhmc -c altdiskboot -s enable --mode upgrade

    Now the HMC is ready to be rebooted and automatically upgraded with the code copied to the bootable disk partition.

06. Finally, reboot the HMC and start the upgrade.

    hmcshutdown -r -t now
