Symptoms
IBM LTO5 drive with A5R0 f/w: The drive will log into all switches and blades and will negotiate a F-port login.
"IBM LTO5 drive with code A9Q5 and later will now try to log into the switch port as a "Fabric Loop" or "FL" device and thus will be reported to the host by the switch with a different FCID and thus would be seen by the host as a completely different drive on the host. This could cause the customer to have to reconfigure their backup application for all of the drives. If the drives "FL" log in is rejected by the switch the drive will then try to log into the switch port as a "Fabric" or "F" device.
Any 8G capable Brocade switch will see the issue.
Those include:
Brocade 300
Brocade 5100
Brocade 5300
Brocade DCX-4S
