Renaming LV Online now possible on AIX 6.1 TL4 onwards

TL4 for AIX 6.1 now allows you to rename logical volumes (LV) while they are still online i.e. open.

In my case, my nimserver oslevel is:

guexnim01(/)#oslevel -s

6100-07-01-1141

root@guexnim01(/)#

Here is an example, my /backup is mounted over /dev/fslv00 filesystem. I am going to rename fslv00 to backlv.

guexnim01(/)#df -g |grep backup ⤶

/dev/fslv00      8.00      1.29   84%     2597     1% /backup

guexnim01(/)#

guexnim01(/)#lsvg -l nimvg |grep backup ⤶

fslv00              jfs2       16      16      1    open/syncd    /backup

guexnim01(/)#

Lets change the name from fslv00 to backuplv, while the filesytem is mounted.

guexnim01(/)#chlv -n backuplv fslv00 ⤶

Lets verify:

guexnim01(/)#df -g |grep backup ⤶

/dev/backuplv      8.00      1.29   84%     2597     1% /backup

guexnim01(/)#

guexnim01(/)#lsvg -l nimvg |grep backup ⤶

backuplv            jfs2       16      16      1    open/syncd    /backup

root@guexnim01(/)#

guexnim01(/etc)#more filesystems |grep -p /backup ⤶

/backup:

        dev             = /dev/backuplv

        vfs             = jfs2

        log             = /dev/loglv00

        mount           = true

        options         = rw

        account         = false

guexnim01(/etc)#
