Sometimes we see our AIX box with a lower oslevel than it really have. Why?
This is due to filesets with a lower level than the system have. What happened?
Let explain that with an example.
Today I have installed AIX 7.1 TL3 SP1 on my box.
‘oslevel’ command shows:
|

|
# oslevel -s7100-03-01-1341 |
Everything is OK but months later I have noted oslevel command shows a lower level. In this case AIX7.1 TL0 SP10, see:
|

|
# oslevel -s7100-00-10-1334 |
What’s going on?
Let’s check which Technology level (TL) my box has installed:

# oslevel -samplesoslevel -rKnown Recommended Maintenance Levels------------------------------------7100-037100-027100-017100-00 |
It says it has 4 TLs and the latest is TL3 when ‘oslevel -s’ command says it has TL0.
So, checking ‘man oslevel’, there are an option ‘-rl’ for ‘oslevel’ command that means:
To list which software is below AIX Version 5.3 technology level 1, type:
oslevel -r -l 5300-01
Running ‘oslevel’ with this option, we’ll see which filesets are causing my oslevel lower:

# oslevel -rl 7100-03Fileset Actual Level Recommended ML-----------------------------------------------------------------------------xlsmp.rte 1.7.0.0 3.1.0.6 |
In this case, fileset xlsmp.rte needs to be updated from version 1.7.0.0 to 3.1.0.6 in order to up to level TL3.
Finally we update OS level from NIM or other media, as shown below:

Now, it’s time to run again ‘oslevel -s’ command and verify it’s OK.
