Downloading Physical Disk Firmware
CAUTION: When updating physical disk firmware, you should stop all I/O activity to the array to
prevent data loss.
The physical disk firmware controls various features of the physical disk. The disk array controller (DAC)
uses this type of firmware. Physical disk firmware stores information about the system configuration on
an area of the physical disk called DACstore. DACstore and the physical disk firmware enable easier
reconfiguration and migration of the physical disks. The physical disk firmware performs these functions:
• The physical disk firmware records the location of the physical disk in an expansion enclosure. If you
take a physical disk out of an expansion enclosure, you must insert it back into the same physical disk
slot, or the physical disk firmware cannot communicate with the RAID controller module or other
storage array components.
