the NetBackup/Flex application. You can hot-swap one of these disk drives at a
time; however, you cannot operate the appliance if both disk drives are removed.
The disk drives in slot 2 and slot 3 are configured as the RAID1, VOLUME1 device.
These disk drives store all of the log files.
The disk drives in slots 4 through 10 store user data. They are configured as a
RAID 6 array, which uses block-level striping with two parity blocks across each of
the disk drives in the volume.
The appliance uses the disk drive that is located in slot 11 as a hot-spare disk. If
one of the disk drives fails in slots 4 through 10, the appliance automatically initiates
a RAID 6 rebuild operation. It rebuilds the RAID 6 array by using the hot-spare disk
drive in slot 11. After you replace the failed disk drive, the appliance then copies
the information from the disk drive in slot 11 to the new replacement disk. When
the copy operation finishes, the disk drive in slot 11 again becomes the hot-spare
disk.
Note: The hot-spare drive size depends on the data drive size.
Warning: The disk drives are pre-formatted before the appliance is shipped. Do
not rearrange the disks from their original locations.
