Description

This document describes the necessary cabling for 2
attached JBODs to a Sun Storage 351x Array . More importantly,
this document displays the disk drive IDs when the 351x 'ID Switch' is
set to numbers 0-7.

Solution


Steps to Follow

To connect a JBOD (Just a Bunch Of Disks) to a 351x RAID Array, where FC2 is a 'drive-channel' 
port on one of the RAID controllers in a dual-controller array setup:
Connect a cable from the top Raid controller's FC2 SFP port to the Upper-Left
JBOD's SFP port (LOOP A). Then connect a cable from the lower Raid controller's FC2 SFP
port to the Lower-Left JBOD's SFP port (LOOP B).

If a 2nd JBOD is attached to the above configuration, use the above cabling scheme and do
the following for the 2nd JBOD:

Connect a cable going from the 1st JBOD's Upper-Right SFP port to the 2nd JBODs
Upper-Right SFP port. Then connect a cable going from the 1st JBOD's Lower-Right SFP
port to the 2nd JBODs Lower-Right SFP port.An additional step is required in configuring
3510FC/JBODs compared to 3310SCSI/JBODs.

Loop IDs on Expansion Units

When an expansion unit is attached to a RAID array, unique, hard-assigned loop IDs are
assigned to each expansion unit drive. A loop ID is the decimal version of an AL_PA.
The lowest number loop ID is the lowest priority address on the loop.

On the left front side of an expansion unit, an ID switch is used to set the loop IDs for
the disk drives to a different range of values so that the same IDs are not repeated on
the same loop (DEVICE ADDRESS CONFLICTS). 3510 RAID arrays also have an ID Switch.
To access the ID switch, open and remove the front bezel, and slightly twist the left
ear cover to remove it. Press the button to change the ID number. After the ID is set,
snap the ear cover back in place and re-install the front bezel.

By default, the ID switch on all 3510FC RAID arrays and expansion units is set to 0,
where the range of IDs is automatically 0 to 12 for 12 drives. The IDs 13 through 15
are ignored. The 3310 SCSI arrays & JBODs do not have an ID switch.
The ID switch offers 8 ID ranges. Each range/set contains 16 IDs.
The last 4 IDs in each range are ignored.
