Refer to the Sun StorEdge 3000 Family Best Practices Manual for the Sun StorEdge 3510
FC array for cabling diagrams for configurations ranging from three to eight
expansion units.
Note –
Large configurations may require the use of one or more optional extended-
length cables, part number X9732A. Other items may also be required. Refer to the
Sun StorEdge 3000 Family FRU Installation Guide for information about supported
cables, SFPs, and other user-replaceable items.
4.11 Setting 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.
Setting the loop ID on an array requires dropping the front bezel out of the way and
removing the small vertical plastic cap on the left side of the bezel that cover the left
rackmount tab. Rackmount tabs are often referred to as “ears.”
