How to know the old os level in AIX

Okay - after a while of poking around, I think I found it.

First, I run lspv to get the list of disks and the volume group:

lspv
power123        pvg11        active
disk1234        pvg12        active
hdisk234        pvg12        active
power345        pvg14        active

Then I take a volume group, and run an lsvg on it:

lsvg -l pvg11
pvg11:
LV NAME             TYPE       LPs   PPs   PVs  LV STATE      MOUNT POINT
varcorelv          jfs2       12203 12203  11   open/syncd    /var/core

It should be easy to write a script to combine these 2 steps.

Thanks to all who helped!

I can do it using just touch, test, and date. (tested on AIX 5.3.0.0)

First you need to create a file 30 minutes in the past (Unfortunately, this requires prior knowledge of the current timezone on the machine. But you may be able to work that into things if need be.)

In this example, the current timezone is EST5EDT (GMT-4). If you're lucky, the machine timezone will be set at GMT and you can just use TZ=00:30:

-bash-3.00# date
Mon 26 Mar 14:22:31 2012
-bash-3.00# touch -t `TZ=04:30 date '+%Y%m%d%H%M.%S'` foo
-bash-3.00# ls -al foo
-rw-r--r--   1 root     system            0 26 Mar 13:52 foo

Now use test to compare the dates:

-bash-3.00# test '/smit.log' -ot foo && echo 'smit.log is older than 30min'
smit.log is older than 30min
