Fibre Channel-to-SCSI Mapping Configuration

For a discussion of Fibre Channel-to-SCSI mapping, see Appendix A. To configure Fibre Channel-to-SCSI
mapping, select item

from the Configuration Menu. This presents the following display:

Fibre Channel to SCSI Configuration Menu

Build Level: a9802

Current Fibre Channel to SCSI Mapping Mode is Auto-assigned

1) Display Attached SCSI Devices, LUN Priority

2) Display Attached SCSI Devices, Target ID Priority

3) Display Attached SCSI Devices, Bus Number Priority

4) Change the Fibre Channel to SCSI Mapping Mode

X) Return to Previous Menu

LUN Priority Display.

To view LUN priorities of attached SCSI devices:

Press

while in the Fibre Channel-to-SCSI Configuration Menu.

The Configuration Menu displays a screen similar to the following:

Target ID Priority Display.

To display the target ID priorities of SCSI devices, select

. This results in a

display similar to the one shown above.

Bus Priority.

Item 3 has no significance on the Scalar 218FC, since it only has one SCSI bus. Selecting this

choice results in the following error:

ERROR:

There is only one bus on this device

Press Any Key to Continue...

Fibre Channel-to-SCSI Mapping Mode.

This allows you to select the way in which Fibre Channel

addresses are mapped to SCSI addresses.

Pressing

on the Fibre Channel-to-SCSI Mapping Mode Configuration Menu displays the following menu of

selections:

Fibre Channel to SCSI Mapping Mode Configuration Menu

Build Level: a9802

Current Fibre Channel to SCSI Mapping Mode is Auto-assigned

1) Set to SCC

2) Set to Indexed

3) Set to Auto-assigned, LUN priority
