Tom,
>From what I understand, LTO2 aren't dual attached drives, so you wouldn't
need the Control Path Failover for your server. Now, the 3592's are dual
attached, but they are enterprise drives and $$$$. Please someone correct
me if I'm wrong concerning the dual paths on the drives...

attach drives (AIX platform)

It is time to upgrade our tape drives - the current lease is coming up for
renewal. I will be replacing LTO-1 SCSI drives with LTO-2 fiber drives. Do
I
need to get the AIX 'Control Path Fallover' option for TSM to properly
recognize that there are two paths to a drive and only use one? My current
understanding is that Control Path Fallover will allow TSM to continue a
process running against a particular tape and tape drive on the second path
if the first fails, as opposed to cancelling the process (and possibly
flagging the tape as unavailable).
Realisticly, how often does a path fail in the real world? We currently
have
two 2019-F16 switches and will be adding two more with the tape drives. We
also have just the one TSM server and are not currently planning on running
anything LAN-free.
TIA
