Has anyone else observed that TSM only reads from COPY1 of a db volume mirror pair during DB backup?
Why do you believe it should do otherwise? As exposited in the Admin Guide manual, mirroring is for disk failover purposes. You can artificially cause both mirrors to be read, via MIRRORRead Verify, but that's for paranoid circumstances rather than standard operation, and exacts a performance penalty. Richard Sims
