Hi Betsy,

I think this time around that I have better news for you. It turns out that I 
was a little out of the loop with our problem. The fix coming in 3.1.2.30 (APAR 
# IX87630, at least for AIX) relates to tape volumes only.

It turns out that an AUDITDB should fix the problems for disk volumes. More 
good news. You shouldn't need to audit your entire database, rather just the 
DISKSTORAGE table.

We tried running a full audit, without the fix option, on our 30 GB database. 
After 3 days my guess is that it wasn't even half finished, so it got canned. 
Doing just the DISKSTORAGE table reduced it to 4 minutes. IBM support have 
suggested that you will get even faster performance by flushed all of your disk 
pools first, particularly if you have caching enabled. But we didn't do that 
and it still ran very quickly. With fix=yes I assume that it will take longer, 
but it should be that much longer.

If I can get a quiet point on our server later today I plan on running it again 
with fix=yes.


regards,

Trevor
