Sorry, I did this before and forgot to post it. I only see the things I expect to see - Active files, and those that RMAN deleted this morning. These are the same items that I see when I do "Show versions NODENAME *" The state of the RMAN deleted items does go from ACTIVE_VERSION to INACTIVE_VERSION. The DEACTIVATE_DATE is blank in both cases. And, yes, the INACTIVE_VERSION records are gone the next day after the inventory is expirerd.
Few more questions :
1) Can you do a "select * from backups where NODE_NAME='YOURNODE';" in TSM? Do you see any old entries beyond your expected retentions?
2) The STATE of a backup changes from ACTIVE_VERSION to INACTIVE_VERSION when you issue a delete from RMAN. What's the corresponding DEACTIVATE_DATE on these INACTIVE_VERSION records?
3) Does the INACTIVE_VERSION record get completely erased after you expire inventory?
