same port ID. In a hub environment, each Symmetrix port must have a

different Hard Loop ID (Target ID).

Example of sd.conf for Arbitrated Loop in a Hubless Environment

The following example is for a hubless loop configuration with a

Target ID (Symmetrix Hard loop ID) of 0.

name="sd" class="scsi"

target=0 lun=0;

name="sd" class="scsi"

target=0 lun=1;

name="sd" class="scsi"

target=0 lun_6;

name="sd" class="scsi"

target=0 lun_7;

Note: Add only those Target/Lun definitions that are needed. In a direct-connect

configuration, it is recommended that all Symmetrix ports be given the same

Target ID. If different Hard Loop IDs are used for each port, lines must be

added

to sd.conf for each LUN of each target. The fewer Target/Lun definitions in

sd.conf, the less time it takes to boot.

Example of sd.conf for Arbitrated Loop in a Hub Environment:

The following example is for a hub loop configuration with two Target IDs of 0

and

1. Each target has 128 luns. For every Symmetrix port assigned to a host, there

must be a target and series of LUNs configured in the sd.conf file. Targets are

determined from the Symmetrix Hard Loop ID. In this example, 256 separate

Target/LUN definitions are added to the sd.conf file.
