Path AIX server using NIM

Can someone please explain me the procedure to patch a UNIX AIX server using NIM. I am planning to upgrade my server from AIX 6.1 TL2 to AIX 6.1 TL6SP6. I have downloaded all the filesets on to my NIM server. So can someone help me with the best practice to upgrade.

Hi,

best practice is creating one lppsource out of each TL package (3, 4, 5, 6). At least the last one should include its pertaining SPs, but it's not a bad idea adding the respective SPs to each of the lppsources.

Then update the client system TL by TL in sequence, from the client itself ("smitty nim_c_update_all") or from the master ("smitty nim_update_all"), as desired.

In most cases you can spare the reboot normally required after a TL upgrade, but don't wait too long between the single upgrade steps.

Another option is merging all TLs plus SPs into one single lppsource.

Upgrading by means of this big lppsource will cause lots of "Already superseded ..." warnings to be issued which can safely be ignored, however.

Attention: In this scenario never ever try to rename the fixes from image name format to package name format by means of "bffcreate -c ...". It often happens that bffcreate wants to rename different images to the same package name, which can result in a big mess. So leave all filesets at their original "U....." image names.

Don't worry about the message complaining about missing simages when creating the lppsource(s). After all, you're going to perform upgrades, not base installations.
