Fibre Channel Guidelines

The following guidelines exist for AMASS running with fibre channel.

HP-UX Fibre

For AMASS users in a HP-UX fibre environment connected to a PathLight 5000 SNC, the environment variable: AMASS_PLSNK should be used.

A known error condition exists where the first SCSI test-unit-ready sent to the device is never received but rather absorbed by the PathLight and a SCSI bus reset status returned. The detected presence of this environmental variable in the UNIX shell will cause AMASS to respond correctly to this condition. This environmental variable can be set in the shell in which AMASS is started or put directly in the amass_start script.

Note	Make sure that if this environment variable is being used to set it in the shell
	before amassbackup and amassrestore are executed.

Solaris Fibre

AMASS supports fibre on the Sun Solaris platform. When installing AMASS, the AMASS juke driver may be unable to attach to fiber attached drives and libraries. If you have this problem, please call ATAC for assistance.

SGI IRIX 6.5 Fibre

AMASS uses symbolic links (/dev/rjuke1, /dev/rj1d1..) that are mapped to system device files.

For example: /dev/rjuke1 ->/hw/scsi/sc7d510

However, the AMASS install process may have trouble creating symbolic links for fibre devices attached to a fabric under IRIX 6.5.14 and later. For instance, after entering the desired controller, target, and Logical Unit Number (LUN), you might receive the following error message.

Failed to build a path to the device for you.

Please enter the explicit device path:

To find the explicit device path, use the following steps. You can also use the same steps to determine the explicit device path for other fibre devices. This example tries to determine the device path for the first device listed in Step 1.

Fabric Tape: node 1000006045170ad2 port 2001006045170ad2, lun 2 on SCSI

controller 8: unknown

1Perform an hinv system call.

# hinv grep -i tape

Fabric Tape: node 1000006045170ad2 port 2001006045170ad2, lun 2 on SCSI

controller 8: unknown

Fabric Tape: node 1000006045170ad2 port 2001006045170ad2, lun 4 on SCSI

controller 8: unknown

Fabric Tape: node 1000006045170ad2 port 2001006045170ad2, lun 6 on SCSI

controller 8: unknown

Fabric Tape: node 1000006045170ad2 port 2001006045170ad2, lun 8 on SCSI

controller 8: unknown

2Look at the contents of the /dev/scsi or /hw/scsi directories and match the output from the hinv system call for the desired device.
