I did a recent install with AIX 4.3.2 and ADSM 3.1.2.0/1 and used raw
logical volumes on SSA disk (my standard fare) and ran into the same
problem. Our level 2 support here in Canada (Rejean Larivee) happened to
have another customer with the same problem. That customer was given a
debugging kernel by AIX support and it showed no AIX errors. Currently
they are getting special ADSM server code to get more information about the
error.
I have another customer who upgraded from v2 to v3 and ran into the same
problem; they backed out of the upgrade. However, a better temporary
workaround is to use files in a JFS. Take your disk, make filesystems, and
use dsmfmt to format large files, and use those for ADSM. You done get the
errors then. When they figure out what is causing the problem and fix it,
then you can switch back.
It would appear that the problem is restricted to ADSM v3 with SSA disks
and raw logical volumes for storage pool volumes. Also, it may only affect
volumes > 2 GB because I have another customer that recently went v2 to v3
but had been on AIX 4.1 so had raw lv's that were all < 2 GB; they did not
experience the problem.
When an answer is found, I'm sure Rejean or I will post the result.
Cheers...
