PS4100 Hardware Maintenance Guide

• If a spare drive is not available and the failed drive is in a RAID set that is already degraded, data may

be lost and must be recovered from a backup.

• If a drive fails, replace it. Do not re-install it in the array.

Drive Handling Requirements

Handle drives as follows:

• Store drives properly. Store replacement drives in the packaging in which they were shipped. Do not

stack drives or place anything on top of a drive.

• Protect drives from electrostatic discharge. Wear an electrostatic wrist strap when handling a drive,

unless it is protected from electrostatic discharge. See

• Handle drives carefully. Hold a drive only by the plastic part of the carrier or the handle. Do not drop

or jolt a drive or force a drive into a slot.

• Warm replacement drives to room temperature before installation. For example, let a drive sit

overnight before installing it in an array.

• Do not leave drive slots empty. Each drive slot in an array must contain a drive assembly or a blank

carrier. Operating an array with an empty slot will void your warranty and support contract.

• Do not remove a functioning drive (other than a spare) from an array. If the drive is not a spare,

the RAID set may become degraded. If you remove a spare, replace the drive as soon as possible.

• Do not remove a drive from its carrier. This action will void your warranty and support contract.

• Keep the shipping material. Return a failed drive to your array support provider in the packaging in

which the replacement drive was shipped. Shipping drives in unauthorized packaging may void your

warranty.

• Replace a failed drive as soon as possible to provide the highest availability.

• Install only drives of the same type, speed, and spin rate in an array.

• Make sure the drive is oriented in the correct position for the array model. See

and Indicators on page

• You can use drives of different capacities in the same array. However, the smallest drive in the array

will determine how much space can be used on each drive. For example, if the smallest drive is 400GB,

only 400GB of space will be available for use on each drive.

• Make sure to insert a drive fully in the chassis before pushing in the handle.

• When correctly installed, a drive will be flush with the front of the array. If the drive is protruding from

the array, reinstall the drive.

• After installation, make sure the drive power LED is green or flashing green. See
