6.7Replacing a Failed Hard Drive

Hard drives for the subsystem can be purchased separately. When purchasing the hard drives, the following factors should be considered:

Capacity (MB/GB): Use drives with the same capacity. RAID arrays use a “least-common- denominator” approach. The maximum capacity of each drive used in the array is the maxi- mum capacity of the smallest drive. Choose big drives with the same storage capacity. Profile: The drive trays and bays of the system are designed for 3.5-inch wide x 1-inch-high hard drives. It is highly recommended that you do not try to use drives of any other size. Drive type: The RAID subsystem described in this manual can use SATA-I or SATA-II hard drives. Please ensure that you purchase the correct hard drives.

CAUTION!

The hard drives and drive trays should only be installed into the subsystem after the subsys- tem has been mounted into a rack cabinet. If the hard drives are installed first, the subsystem will be too heavy to lift and the possible impact during installation may damage your drives.

CAUTION!

Handle hard drives with extreme care. Hard drives are very delicate. Dropping a drive onto a hard surface (even from a short distance) and hitting or touching the circuits on the drives with your tools may cause damage to the drives.

Observe all ESD prevention methods when installing drives.

Only use screws supplied with the drive canisters. Longer screws may damage the drive.

Hard Drive Maintenance Overview

•

•

Hot-swappable drive trays: The drive trays are all hot-swappable. If a hard drive fails, it can be replaced while the subsystem is still running.

Handles: If the failed hard drive is behind either the left or right front handle, unfold the handles to open the front access to the drive trays. (See Figure 6.19)

•

Open flap: Once the flap on the drive tray has been opened, the drive tray must be removed from the subsystem. Failure to remove the drive tray from the subsystem after the flap has been opened may cause data errors.

Remove drives slowly: When removing a drive tray from the RAID subsystem, pull the drive tray out only about one inch and then wait for at least 30 seconds for the hard drive motor to spin down before taking it out completely. Any impact to the hard drive while the drive motor is spinning can damage the drive.

Keep a replacement on hand: If a hard drive has failed, make sure you have a replacement hard drive readily available before removing the failed drive from the subsystem. Do not leave the drive tray slot open for an extended period of time or the normalized airflow will be disrupted and subsystem components will overheat and may become permanently damaged.
