PS6000 Hardware Maintenance

Disk Handling Requirements

Handle disks as follows:
• Store disks properly. Store replacement disks in the packaging in which they
were shipped. Do not stack disks or place anything on top of a disk.
• Protect disks from electrostatic discharge. Wear an electrostatic wrist strap
when handling a disk, unless it is protected from electrostatic discharge.
• Handle disks carefully. Hold a disk only by the plastic part of the carrier or
the handle. Do not drop or jolt a disk or force a disk into a disk slot.
• Warm replacement disks to room temperature before installation. For
example, let a disk sit overnight before installing it in an array.
• Do not leave disk slots empty. Each disk slot in an array must contain a disk
drive assembly or a blank carrier. Operating an array with an empty disk slot
will void your warranty and support contract.
• Do not remove a disk from its carrier. This action will void your warranty
and support contract.
• Keep the shipping material. Return a failed disk to your array support
provider in the packaging in which the replacement disk was shipped.
Shipping disks in unauthorized packaging may void your warranty.

Identifying Failed Disks

Disks in a PS6000 array are numbered from 0 to 15 (from left to right, top row to
bottom row). A disk failure is indicated by:
• LEDs on the disk. See Interpreting Disk LEDs on page 2-2.
• A message on the console, in the event log, or in the Group Manager GUI
Alarms panel describes a disk failure.
• The GUI Member Disks window or the CLI
command shows a disk failure.

Array Behavior When a Disk Fails

How an array handles a disk failure depends on whether a spare disk is available
and whether the RAIDset containing the failed disk is degraded.
