Fibre Channel Problem Determination
Before starting, check the Fibre Channel topology. Verify a problem exists
between the drive, drive cable, and the device to which it is attached. Use
switch, hub, or other fibre product documentation as appropriate.
If the problems are due to the drive or the fibre cable connected to the drive:
1.
Verify the drive power is ON.
2.
Verify the drive serial number is the same as the drive serial number being
used by the host program detecting the problem.
