When a TLU (tape Library Unit) is directly attached to a fileserver, does every reboot of the TLU necesarily mean you must reboot the fileserver? OR Is this only specific to the TLU vendor ( as suggested below).
Hot swapping anything on a SCSI bus is "not supported" but will work 90+% of the time.
In other words, it'll almost always work, but on the most critical time when you really can't afford any down time, you'll be mucking with a SCSI bus at just the wrong moment and Bad Things Will Happen.
I hot swap SCSI things on non-production systems all the time because I'm lazy, but if I'm going to be in big trouble if the thing fries, I take the time to schedule proper downtime. If a filer fried, I'd be in big trouble, so I don't hot swap SCSI stuff on it.

ps. I may have confused terms--You can certainly hot swap anything designed for hot swapping, such as disks in the more recent filers. I'm talking about the SCSI bus that's directly attached to the filer itself, and which is not designed for hot swapping, at least not in any filers I've seen.
