One note about conventional wisdom: *always* mirror with hardware when
possible. Hardware mirroring is faster and more stable. (Hardware
anything--mirroring, compression, encryption, etc.--is almost always
faster and more stable.)

The only reason TSM ever contained dbvol and logvol mirroring abilities
was to accommodate the ADSM server port to Windows, which at the time had
no mirroring capabilities.
