|It is vital that you regularly visit IBM Fix Central and check for
firmware updates and fixes as failing to
keep them up to date can invalidate your support agreement.
Whenever you install an AIX update such as a TL or SP it may include some firmware updates and there
is a danger that the firmware on your cards is newer than that in the frame, and this can cause unpredictable
IBM provides the invscout utility which generates XML reports that can be uploaded to the IBM, webserver
which then automatically diagnoses your firmware and produces a report.
This is the IBM invscout manual page:
You can also view a summary of your microcode from the command-line as follows:
sys0!system:SF240_417 (t) SF240_403 (p) SF240_417 (t) ent0!14108902.DV0210 ent1!14108902.DV0210 ent2!1410ff01.SCU015 sisscsia0!44415255.070A0011 ent3!1410ff01.SCU001 ent5!14106902.GOL021 cd0!IBM-DROM002054.P633 rmt0!C105 hdisk2!ST37320.4A553042.43373041 hdisk3!ST37320.4A553042.43373043 ent4!14106902.GOL002 hdisk0!ST37320.4A553042.43373041 hdisk4!ST37320.4A553042.43373041
Your system has two copies of firmware in case an update fails or you want to test two versions.
The version that the system boots from can be selected from the firmware.
