Hi *SM'ers,

We are looking into the possibility of placing TSM DB mirror volumes on
remote SAN devices. Has anyone already done this, and have any gotchas
or issues?

My first concern would be latency, but With mirrorwrite sequential it
seems from the explanation that the primary mirror volume is the one
that would be hurt by latency, not the secondary mirror volume.

Would that be the case? Or, will TSM wait for the secondary mirror write
to finish before embarking on the next primary mirror write on that DB
volume?


Matt.
