Wondering if anyone knows how to determine when an AIX 5L system was installed?

Many thanks...

Hi,

Run:

lslpp -h bos.rte

And look for the entry for your oslevel.

What about if the system was created from a mksysb image? Will the output from the lslpp -h bos.rte command report when the local system was created, or when the mksysb's parent system was created?

It should be the parent's since AIX is not going to modify the ODMs to fix
all those dates.

ls -l /var/adm/ras/bosinstlog should tell you when the box was loaded.

Nope - that changes each time the OS is updated, so it will show the latest date the OS wa updated, but not the original install date.

But if my mechine installed on a fault date,they changed the date later. So the date in the log file is wrong. How to deal with?

what abt checking the root filesystem is creation time stamp? I assume that it is created when we do install.

/usr/sbin/getlvcb -AT hd4
AIX LVCB
intrapolicy = c
copies = 2
interpolicy = m
lvid = 0000eeba0000d3000000010d4108dd6e.4
lvname = hd4
label = /
machine id = XXXXXXXXXXXX
number lps = 2
relocatable = y
strict = y
stripe width = 0
stripe size in exponent = 0
type = jfs2
upperbound = 32
fs = vfs=jfs2:log=/dev/hd8:mount=automatic:type=bootfs:vol=root:free=true
time created = Thu Aug 24 16:34:58 2006
time modified = Thu May 10 20:00:14 2007

Hi,

 

have to update this thread as I stumbled upon it after I was asked for an installation date of one of our AIX systems by CMDB mgmt.

Meanwhile, AIX systems are patched via alt_disk_copy and the rootvg will be re-created, so the timestamp of the LV creation will not count as well.
 

Partial solution which works fine for me:

In case the system was installed by NIM there will be a first boot script located in /etc which has the time stamp of the installation as its filename. In case there are multiple ( because of image maintenance ) you have to take the latest.

 

 # ls -ltr /etc/fb_*
-rwxrwxr-x    1 root     system          598 Oct 29 2010  /etc/fb_14_41_10_29
-rwx--x--x    1 root     system          422 Mar 25 2011  /etc/fb_09_02_03_25

 

pretty sure the overall valid answer for this question is somewhere out there as well...

 

Have fun...
