select the controller in the tree view and the microcode version is displayed.
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 2 RAID disk numbering
In Storage Utility, Level 2 RAID disks are numbered with a normal decimal sequence,
starting with zero (0, 1, 2, 3, etc.). However, it is important to note that there is no disk
15. The primary RAID chassis contains disks 0 through 14, while the Expansion
Chassis contains disks 16 through 30.
Level 3 RAID disk numbering
In Storage Utility, Level 3 RAID disks are numbered with a hexadecimal convention,
as follows:
Disk Firmware
