I have Tape Libaray TS3100 with two FC Drives and two Brocade B300 san switches.
my question is about connectivity of Tape Libaray with SAN Switches.
i have been connected to One FC drive with SAN Switch-1 and Second Drive connect to SAN Swicth-2 am i correct or not ?
Most tape libraries do not allow multipathing. Most tape libraries should be connected to a single fabric only.
Depending on the controlability of the tape library, there are "creative" ways that a TL could be connected to a dual fabric. But, that does require that each tape drive in a library be single fabric only. I've only seen this done once and that device would be hard pressed to be truely called a "library".
From my experience, you may connect drive to both fabrics. After link failure you may switch to second path and reschedule backups.
Unfortunatelly i don't remember now if its driven by tape library or backup software.
Thank you for your reply and Support . The issue has been resovled.
