When using MegaRAID BIOS or Power Console, the program identifies the drives as Ax-N.
Ax represents the logical drive (the array of disks, or the disk array) of the cabinet that the
drives are a part of, and N represents the disk drive number within the logical drive.
NOTE For detailed information about using the MegaRAID BIOS or Power Console, refer to the
InterRAID documentation.
The following table shows the correlation between the standard disk drives, their bay
location, drive label, and how they are identified in MegaRAID BIOS and Power Console
(MegaRAID ID).
