prompt>instfix -i |grep ML
All filesets for 5.2.0.0_AIX_ML were found.
All filesets for 5200-01_AIX_ML were found.
All filesets for 5200-02_AIX_ML were found.
All filesets for 5200-03_AIX_ML were found.
All filesets for 5200-04_AIX_ML were found.
All filesets for 5200-05_AIX_ML were found.
All filesets for 5200-06_AIX_ML were found.
All filesets for 5200-07_AIX_ML were found.
All filesets for 5200-08_AIX_ML were found.
All filesets for 5200-09_AIX_ML were found.
All filesets for 5200-10_AIX_ML were found.

And they show the same oslevels:

prompt>oslevel -s
5200-10-05-0819

But if I look at all the individual "All filesets for IYXXXXX were found." and "Not all filesets for IYXXXXX were found." messages from "instfix -i" I see a few differences where they are found on one server but not the other (one shows the below and the other shows the same but "not found"):

    All filesets for IY78159 were found.
    All filesets for IY78873 were found.
    All filesets for IY78922 were found.
    All filesets for IY78923 were found.
    All filesets for IY78924 were found.
    All filesets for IY78930 were found.
    All filesets for IY78932 were found.
    All filesets for IY78933 were found.
    All filesets for IY79071 were found.
    All filesets for IY79422 were found.
    All filesets for IY80656 were found.
    All filesets for IY80737 were found.

I was told that since all the maintenance levels are up to date that we should ignore these differences, because they were likely due to manual installation of those filesets in question. I'm suspicious of this answer.

Is it true that since they have the same ML and oslevel -s output that they have identical patches applied? Or are the 12 individual fileset messages above really differences between the two servers?

If instfix and oslevel show the same level then you can be sure they are at the same level but your difference seems to indicate one has an XL c compiler installed and the other has not, I'd look at the installed filesets or pacakages next to find out more about these differences.

Thanks dukessd, that helps a lot.

I guess what confused me is the full listing of the "instfix -i" command. All of the service pack (SP) and maintenance levels (ML) look the same and say they are complete. But those 12 fileset messages were in the instfix output for only one of the servers.

Are you saying that those 12 messages are appearing only on one of the servers because they apply to a package that is not on the other server? In general, a ML could contain fixes for packages that are not installed so they can still be at the same ML but show fileset differences because some of those filesets could apply to packages that are not present. Is that right? How did you determine that those are related to the XL c compiler?

To compare the list of installed filesets and packages, I'll just run "lslpp -L" or is there a better way?

The base OS level can be the same on two systems but they can still have different fixes installed due to:
1) the fix that is applied doesn't change the base OS level
2) there is other software installed such as xlC that isn't part of the base OS

The previous poster said it looks like you have xlC installed because if you look up those fixes, they apply to xlC.

If you want to compare every fileset installed on two systems, you'll have to script it up. You may be able to find a script from someone else since this is pretty common activity when building a new server to match an existing one.

Hello,
instfix will show information about APARs only for installed filesets.
Even though the ML/SP might have information about APARs pertaining to those filesets that are not installed, instfix will not report them.
As in your output IY80737 apply to xlC, so instfix will report it if xlC is installed, and will not report it if not.
If you want to verify which filesets those APARs apply to you can use :
instfix -icqk "IY78159 IY78873 IY78922 IY78923 IY78924 IY78930 IY78932 IY78933 IY79071 IY79422 IY80656 IY80737"

Hope this help.
