Tell us something about your SAN ...
Are you in a fabric environment, or a loop environment ? Are the
drives fabric enabled drives in Point-to-point mode or are they Public
loops attached to your fabric (if you have one) ?
If you are in loop mode, a LIP (loop initialization) or target reset
might cause your drives to get a new ALPA (= address on the loop)
effectively preventing your host from talking to the drive.
Do you use persistent binding ?
