Hi I did exactly this last week but I used migratepv instead of the mirroring approach. I was moving from ds8100 to ds8870. Mirroring method will be fine.

Such as the TSM DB2 database. The manual says to do a full database backup and restore. That could take days of downtime with our 150-300GB databases, and a lot of angst, so that is not really acceptable. What I'm planning to do instead, is what I've always done on AIX. It's one of the reasons I like AIX for hosting something like TSM. That is, to basically walk the database over to the new location using AIX LVM mirroring. All this with TSM up and running, albeit with a performance impact. (It's Spring Break, so the performance impact is acceptable.) The end result will be that the database has exactly the same Unix filesystem names, path names, and file names as before, except that it will be on a nice new faster disk subsystem. Other than the obvious performance impact while AIX LVM is doing the mirroring, is there anything wrong with moving a TSM DB2 database by this method? Anybody done this and had problems?
