Removing and Installing a Hard Disk

Problem

The JA1500 appliance ships with three hard disk drives in RAID 5 array. The hot-swappable and hot-insertable drives are externally accessible in field-replaceable trays. You can remove and replace a hard disk without powering off the appliance or disrupting functions

If one drive fails, the appliance recovers by automatically rebuilding the failed drive. During failure, the LED 2 on the right on the front of the hard disk tray turns solid red and an alarm sounds . See Figure 10.

Caution: RAID system performance is impacted during the hard disk recovery process. The rebuild process can take between one hour and a day depending on the system load.

Solution

Before you begin removing a hard drive from a JA1500 appliance, ensure that you have taken the necessary precautions to prevent ESD damage.

To remove a failed hard disk and install a new one:

1. Place an antistatic bag on a flat surface.
2. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the JA1500 appliance
3. Loosen the hard disk captive screws. See Figure 11.

4. Slide the hard disk tray out of the appliance.
5. Put the failed hard disk in the antistatic bag for return material authorization (RMA).
6. Remove the new hard disk from the antistatic bag.
7. Insert the new hard disk into the JA1500 appliance and secure the two captive screws. See Figure 12.

   The alarm silences and LED 2 starts blinking indicating the new hard drive is recovering RAID volume. LED 2 stops blinking when the drive rebuilding is complete and normal operation is established.
