Identifying Disk Drive Modules
You can identify a disk drive module by the serial number that appears on a label
«1¬
on the front of the module:
This label also shows the capacity of the disk drive.
Each disk drive module also has a FC-AL address that is related to its position in
the ProFibre Storage Array unit.
The addresses used are S0 to S9 (hex) where S is the setting of the address switch
on the switch card. These addresses are assigned, in sequence, from left to right.
