I am looking for suggestions on how to handle moving large TSM clients between TSM servers and maybe some corrections to my understanding of how EXPORT/IMPORT handles error situations.
I need to move TSM clients from my zOS server (being phased out) to my AIX TSM server. The problem is, some of these systems have > 1TB of data to move. When I tried to move a 500GB client (250GB actual since the copypool data is not moved), the export/import ran for >40 hours before failing on a tape drive failure (190GB moved). My understandings are that: 1. During the E/I the client is locked/can not be performing backups on *EITHER* system. This means the client has to go without *ANY* backups for the duration. This is generally not acceptable ! 2. If the E/I fails like it did, I have no recourse but to delete what was successfully sent, and then start all over again. Doing a MERGE FILESPACES is only going to save me the issue of it creating multiple duplicate directories with the same name +1. It still will work through all 40+ 3590 tapes. So, how do you handle situations like this ? If 190GB took 2-days, 1TB will take > week with me praying for no tape drive failures (or TSM server crashes like it did earlier in the week with a U301 abend/known problem). The zOS server only has access to a 100MB connection. Both TSM servers are 5.2.3.4. I will be upgrading to 5.3 as soon as I can.
