Replacing the Disk Drives
ARX-2000 Hardware Installation Guide A - 5
Replacing the Disk Drives
Replacing disk drives in the ARX-2000 is a hot-swap procedure and does
not require powering down the switch nor does it involve a loss of service.
If you do not replace a failed drive, the system continues to run, in a
degraded state, with the disk missing from the RAID set. Best practices
dictate that you replace failed disk drives and that you replace them on the
secondary (backup) switch only.
Simply replacing a failed disk does not incorporate the newly-installed disk
into the RAID set nor does it initiate the process of rebuilding the RAID set.
After replacing a disk, be sure to rebuild the RAID set. For instructions, see
Rebuilding the RAID Set, on page A-7 .
Note
To achieve maximum performance on the active switch and avoid service
interruptions, rebuild the RAID set on the backup switch.
As shown in the following figure, the ARX-2000 contains two hot-swap,
hard, disk drives.
Figure A.4 Front Panel Showing Disk Drives
The CLI designates the disk drives as Bay 1 (top drive) and Bay 2 (bottom
drive). As can be seen in
Figure A.4 , the bays are clearly labeled on the
switch.
The system notifies you of an internal disk failure through the CLI or an
SNMP trap. If you receive an e-mail notification of a internal disk failure (or
potential failure), consult the
ARX SNMP Reference, Disks (Internal to the
ARX) .
Important
Before replacing a drive, verify that the bay number (of the drive you are
about to replace) matches the bay number of the failed drive (from the CLI
or the SNMP trap).
