Step

Action

Step 1

Verify that the proper device drivers were installed.

Step 2

Verify that the fibre cable is securely connected to the HBA and the switch.

Step 3

Verify that the SCSI bridge is properly connected to the library and the switch. Apply normal SCSI troubleshooting techniques at the fibre to SCSI bridge. Use a bridge administration tool to verify that the bridge recognizes all of the devices. Also verify that the bridge firmware is up to date.

Step 4

Check for a failed hardware component between the server and the switch. Sometimes some of the servers in the SAN recognize the tape devices, but other servers do not. If none of the servers in the SAN recognize the tape devices, check for a failed hardware component between the switch and the tape devices.

Step 5

Reset the SAN, which may identify problem hardware components and may resolve fibre problems.
