This is slightly off topic, but I would like to receive feedback as to
the steps you take when tape drives are to be powered off for
maintenance work.  There are concerns that if done improperly, dev/rmt
entries can change, ghost drives may appear, etc.  I have heard
everything from:
1.  No need to do anything
2.  Disable the HBA's
3.  Disable the Switch
4.  Reboot the server

We are an IBM 3590 H1A tape SAN shop fiber connected to a McData 4500
switch with A6795A 2 GB Fibre Channel Adapters.
The Media Servers are RP7410's running HP-UX 11i w/ NBU 4.5 MP2.

What are the best practices that you use and advise=3F

Thanks a lot ...=20
