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 Tom Kauffman NIBCO, Inc
