6.8Configuring the Fibre Channel SCSI Devices Interface

To establish the SCSI device configuration the Fibre Channel Option is commanded to “Rescan” its three SCSI device buses. The three SCSI device channels, starting with Channel 0, begin scanning for SCSI devices using ascending SCSI Target Ids. After all three channels have been scanned, the FCO builds a SCSI device table, that it uses to map SCSI Targets to the host as logical devices (LUNs).

Dual Bay Library with two FCO’s

For single bay libraries or dual bay libraries with only one Fibre Channel Option in- stalled, press the V (UP) or W (DOWN) key to move the pointer to Device. Press the ENTER key to enter the Configuration\Fibre Channel\Device menu.

For dual bay libraries with two Fibre Channel Options installed, press the V (UP) or

W(DOWN) key to move the pointer to either Device Left or Device Right. The left and right orientation is as viewed from the front of the library. Press the EN- TER key to enter the Configuration\Fibre Channel\Device (Left or Right) menu.

The Configuration\Fibre Channel\Device menu panels display a list of SCSI devices attached to the Fibre Channel Option. A TLS library with a single Fibre Channel Option displays the title CFC···········Device. A dual-bay library with two Fibre Channel Options installed, displays the title CFC······Device Left or CFC·····Device Right to correspond to the Fibre Channel Option in the left and right side.
