How do I display the version and maintenance level of the operating system on which. For example, this output shows AIX V6.1 Technology Level 8. Install Date.

This little blog post will first explain how to check the previous AIX Technology Level (TL) which was installed before an upgrade and then we will venture into how to rollback the AIX TL, or Service Pack, to a previous version. After an upgrade has been performed you can only check the Technology Level (TL) that was installed previously if the TL fileset, or service pack, still exist on the system and this will be reported by the oslevel command with the –qs option, like so: oslevel –qs Also you could check the SMITTY or SUMA log file to see what the TL was before the upgrade was started. If you’re wishing to see the fixes which are currently on the system for the TL you are at you can use the following command: instfix –i grep TL And you can use the lppchk command to check system consistency like so: lppchk -v Now to the fun part.

Dell Inspiron 1545 Manual more. Rolling back the TL. A word of warning first, I would not recommend rolling back a service pack or TL since it is not well supported due to the fact that some software on the system could rely on specific fixes or a specific TL to be installed for it to operate properly. You will find some commands below, specifically instfix and lppchk which you can use to check the dependencies of software on your system.
