Well, I'll take a shot at this. Haven't worked with 3590 tape in a while but your questions are applicable to any tape.
1. If these tapes were removed then your onsite and/or offsite reclamations should start failing soon as they try to use a tape that isn't there. 2. If your know which tape volser's were removed, then do a "q vol blah f=d" on them and see what stgpool they were in and when last accessed. Maybe if actlog retention is long enough, you can do a q actlog and search for volser and see when removed and by what command. 3. Simplest but could be looonnnng output - do a "q content" on the volumes. This will show you all the nodes and files that are on this tape. You can use some SQL selects to get a more refined list if needed. 4. Even though data may be "expired" it is still on the tape, but not easily accessible unless you have a DB backup tape made at the time the tapes were removed. 5. I don't know the fine details on how data is written on tape but believe there is little or no "indexing" on the tape, it's all in the the DB. (Now some tape tape technologies have "some" kind of information in the header - like the VCR on 3570 tapes). 6. As a summary, it depends on how important the data is that you need back. And if there is classified data on these tapes, how will "they" get that back without you? David Longo >>> [EMAIL PROTECTED] 09/23/02 06:08PM >>> I hope someone has a real good knowledge of how TSM data is written to/read from tape. I'm in a predicament that I may never be able to get tapes back to read any node data off of them unless I can satisfactorily answer questions. Unfortunately I don't know the questions yet so I don't even know what to ask here. Perhaps someone who is knowledgeable about 3590 tape technology or someone from Tivoli monitoring the list can help with this. I hate to have to call Tivoli since so far I haven't got much in the way of answers on the other questions I've been asking on classified material on tape. What kind of questions would you expect to answer if a tape was removed from the library with mixed node data on it and it was needed to restore some other node's data. Keep in mind that the tape was removed because it originally had classified material stored on it. It may or may not still have the data depending on expiration. I already know how to explain the ins and outs of expiration/reclamation but we all know the "DATA" is really still there. My guess is I'm never really going to be able to get these tapes back and whatever data was on them is probably gone forever but I need to at least be able to answer some questions like are they indexed or how the data is stored, how it's read back etc. Thanks for the help, Geoff Gill TSM Administrator NT Systems Support Engineer SAIC E-Mail: <mailto:[EMAIL PROTECTED]> [EMAIL PROTECTED] Phone: (858) 826-4062 Pager: (877) 905-7154 "MMS <health-first.org>" made the following annotations on 09/24/2002 11:14:40 PM ------------------------------------------------------------------------------ This message is for the named person's use only.
