When you say no tape backup produced, I am going to infer that you mean no tapes are being produced for offsite storage. If this isn't happening, you MAY have run out of scratch tapes. The following select will display storage pools that are close to their limit of tapes:
select stgpools.stgpool_name, stgpools.maxscratch, count(*) \ from stgpools , volumes \ where stgpools.stgpool_name = volumes.stgpool_name \ and volumes.devclass_name = '3590' \ group by stgpools.stgpool_name, stgpools.maxscratch \ having stgpools.maxscratch-count(*) < 4 If you have any storage pools that are using their total complement of tapes, you need to give them more: update stgpool <pool name> maxscratch=<a higher number than it has now> The other possibility is that you have run out of scratch tapes entirely. To account for all your current tapes: q vol -- lists all tapes in storage pools. You might count them by status and access type, recognizing status=readonly and access=unavailable as error conditions. status=empty is unusual unless access=offsite. q libv <library name> status=Scratch -- lists all scratch tapes in your library q volhist type=dbb -- lists all the TSM database backup tapes This SHOULD account for all your tapes (onsite or off), except that I have occasionally found that offsite TSM database backup tapes can get "lost" when they come back ... usually a checkin error. You could try a "checkin scratch search=yes" type checkin command or look for q libv <libname> status=private tapes that are not listed in q vol. (If I find any of these I usually just update their status to scratch). If you can account for all your tapes but you still have no scratch, check to make sure expiry is happening. (q pr), perhaps run expiry explicitly ( expire inventory) and watch for what happens (q ac se=expir). Another thing to check for is offsite copypool tapes in need of reclamation (pct_reclaim > say 60). Remember to always set reclaim down from 100 slowly. If you set reclaim on a storage pool directly to 60, it may take several days to reclaim all available tapes at the 60 percent level. You may have to settle for a higher reclaim percentage (say 80). Note you can generate scratch tapes by temporarily deleting more TSM backup than normal (to get reclamation running again). If you can account for all your tapes, but you have no scratch and expiration and reclamation are both running, you may simply need more tapes (or review management policies and keep fewer copies).
