Identifying disks
When you do maintenance or service work on your RAID storage, it is important for
many tasks that you positively identify the disk or disks on which you are working.
Your primary indicators for this are the numbering of the disks in Storage Utility and
the ability to flash the disk LED on a physical disk or a group of disks.
Level 10 - 35 RAID disk numbering
In Storage Utility, Level 10 through 35 (SAS and SATA) RAID disks are numbered
with a hexadecimal convention. Disk modules are identified based on the chassis
address and physical location, as explained in the following sections.
Level 10, 20, and NL10 disk numbering
When Expansion chassis are all connected to DP0, as in Levels 10, 10R, 20, 20R,
NL10, and NL10R, disks are numbered as follows:
