You can power off the "server" (running VMS I assume ?") without shutting down the OS, but of course better first do an orderly shutdown.

After connecting the replaced tape drive, it should be visible on the system automatically, provided all connections and the SCSI ID are o.k.
You usually can check it alread before booting VMS at the console level, depending on the system. On an Alpha (AXP) system the console command is
SHOW DEVICE

If the question in fact meant "Can I replace a SCSI connected tape drive without powering off the server ?" then the answer is:
Don't do it, except if the connector/mounting bay is of the "hot plugguble" type, I doubt that a tape drive is of this type.

Said that, if You really take the risk, be aware that there can be errors in I/O operations on disks connected to the same scsi bus.
After replacing the drive, it has to be made known to the system using the "IO AUTOCONFIGUE" command in SYSMAN, unless the system is rebooted.

The topic does not match what you are asking which leads me to wonder...

Are the backups taking a long time which you believe is due to a bad drive or is the drive known to be bad and you are just trying to replace it without a powerdown?

If the backups are too long, there are many causes of this. Do you have compaction turned on for the drive? This is a hardware function that compresses the data before writing to tape. This translates into less tape being required which can significantly reduce backup time.

Please provide more details.

Thanks,
Dan
