PS6500 Hardware Maintenance

Disk Drive Requirements

Follow these disk drive handling requirements:
• Protect disk drives from electrostatic discharge. When handling a disk drive, always wear an electrostatic
wrist strap or a similar protective device. See Protecting Hardware from Electrostatic Discharge on page 1-7.
• Handle disk drives carefully. Hold a disk drive only by the plastic part of the carrier. Do not handle a disk
drive solely by the release lever.
• Insert a disk drive properly. Do not force a disk drive into a slot. Make sure the disk release latch is oriented
toward the rear of the array.
• Warm disk drives to room temperature before installation. For example, let a disk drive sit overnight
before installing it in an array.
• Do not remove a disk drive from its carrier. This action will void your warranty and support contract.
• Maintain array cooling. When installing disks in an array with power, maintain adequate cooling by
minimizing the time that the chassis cover is open. Do not remove a failed disk until you are ready to replace it.
• Install the same type of disk drives. Install only disk drives of the same capacity, speed, and spin rate in an
array.
If an array contains disk drives with different sizes, in some cases, the smallest disk drive in the array will
determine how much space can be used on each disk. For example, if the smallest disk drive is 400GB, only
400GB of space will be available for use on each disk.
• Do not remove a functioning disk drive from an array. If you remove a spare disk drive, replace it as soon
as possible.
• Store disk drives properly. Store replacement disk drives in the packaging in which they were shipped.

Removing Disk Drives

To remove a disk drive from an array:
1. Identify the drive you want to remove. You can obtain this information from the event log and the disk LEDs.
See Disk Drive LEDs on page 2-1 and Figure 2-4.
2. Use an electrostatic wrist strap or a similar protective device. See Protecting Hardware from Electrostatic
Discharge on page 1-7.
3. Remove the bezel. See Removing and Installing the Bezel on page 1-8.
4. Unlock and open the chassis cover. See Opening and Closing the Chassis Cover on page 1-9.
5. Confirm the disk drive you want to remove. The LED on a failed disk drive will be lit (yellow).
Note: The LED on the failed disk is closer to the release latch for the adjacent disk than it is to the release
latch on the failed disk. See Figure 2-5.
