Wrong TL(Technology Level ) in AIX after upgrade ( oslevel –s , oslevel -r )

After migrating a server from 5.3 to 6.1, I checked the server oslevel as below table and it was showing 6100-04-09-1112 but actually I tried to migrate the server to 6100-06-05-1115 , there is a mismatch in the Technology Level . This is a very common issue in AIX I have encounter this error mulipule time in many upgrades whether it was Service Pack upgrade , technology Level upgrade or Migration etc . Here in the below example we have only one fileset missing but there might be multiple filesets in other cases.

root@webmanual / $ oslevel -s 6100-04-09-1112

Then I check oslevel -rl 6100-50 , shows which filesets on the system are below the given TL level as below

root@webmanual / $ oslevel -rl 6100-06 Fileset                Actual Level          Recommended ML —————————————————————————– tivoli.tivguid        1.1.0.0                  1.3.3.1

Hence here tivoli.tivguid fileset is below the recommended level , so the Technology Level is showing  as 4
To get to the correct TL 6 we need to install the fileset with recommended level

From the man page of oslevel

I had TL 6 SP 5 pacakge downloaded in another server so I found the fileset there and mounted  it to the local server as below . We can use NIM lppsource also ( Recommended).

$ df -g /mnt Filesystem GB blocks Free %Used Iused %Iused Mounted on Webmanual01:/aixupgrade 15.00 10.50 31% 1461 1% /mnt

I moved to the installation directory by using cd command “ cd /mnt/AIX6ML5 “

root@webmanual /$ pwd /mnt/AIX6ML5

To install the recommended fileset I followed the steps as  below
Step 1 : Smitty Install
Step 2 : Select Install Software

Step 3: As I am already in the directory where the filesets exists so I have given . dot otherwise you have to give full path

Step 4: Select filesets ( Here only one) to install in SOFTWARE to install by press F4 or Esc + 4 as below two screens


Once you locate the fileset press F7 to select the fileset and press enter two times
Step 5 : On successful completion of installation it will show OK as bleow

Step 6 : Now I have check the oslevel and it was correct
$ oslevel -s
6100-06-05-1115
