My retention is 2 months, actually. The tape I used on 2008-07-02 was made 
on 2008-04-28, so it was over 2 months old. The tapes in the library were 
almost certainly labeled after 2008-04-28, I think, yes.

Hmm. I did not know about the 2 volids.

Did that multiple times; it didn't help. Removed tmp, and the mm db. Did 
nsrck -L6 and nsrim -X. Did controlled scavenging. I still had the WISS 
errors, even after that procedure. So Tech Support walked me through 
mmrecov.

At the moment (tape labeling aside), it seems to have helped. At least I 
can run a bootstrap again. :-) (savegrp -O -l full -b Bootstrap) Even that 
was badly failing, the other day. Next up with be to run a group. Then run 
2 groups at once - that was causing me to invariably fail; "lost 
connection to server" messages, jobs never ending, all sorts of havoc and 
grief. Certainly not what I need right before a major holiday. And my 
birthday. :-)

Fingers crossed.
