Disk Drive Replacement

The following section describes the procedures for replacing disk drives on the WF-500 appliance. The WF-500 appliance has 24 disk drive bays. Starting from left to right, the bays are labeled A1-A2, B1-B2 up to L1-L2. Only the first four drive bays (A1-A2, B1-B2) are

Disk Drive Replacement available for use. Drives A1-A2 are a RAID 1 pair; drives B1-B2 are also a RAID 1 pair. The only drive maintenance you will need to perform is a replacement of a failed drive in one of the RAID pairs.

Note:

The disk drives in the front drive bays of the WF-500 appliance are hot swappable. For more details on replacing failed drives, refer to the

Replacing a WF-500 Appliance Disk Drive

This section describes the steps needed to remove and install a WF-500 appliance disk drive in the event of a drive failure in one of the RAID 1 pairs.

Place an anti-static wrist strap on your wrist and connect it to ground.

Identify the failed drive indicated by the red LED on the drive bay. You can also check the drive status by running the CLI command show system raid. You will see Disk Pair A and Disk Pair B and the failed drive will show Missing or Failed.

Press the purple button on the drive bay for the failed drive to be replaced as shown in

Figure 11.

Gently rotate the drive bay lever away from the drive until it stops.

Gently pull on the lever to remove the drive from the system.

Figure 11. Disk Drive Replacement

To install a new drive in the appliance, you will need to remove the old drive from the drive carrier. Place the failed drive/drive bay on a flat surface with the label side down and place the new drive next to it.

Disk Drive Replacement

Remove the four screws holding the drive in the drive bay and then remove the failed

disk drive. Figure 12 shows how the drive connects to the carrier.

Note:

If you are using a blank carrier that does not have a drive, a plastic blank will be in place of the drive. Remove the plastic blank before installing the new drive.

Figure 12. WF-500 Appliance Drive Carrier and Drive

SAS

Put the new drive in the carrier and attach it to the carrier with the four screws as shown

in Figure 12.

The drive bay lever should still be in the open position; if it is not, press the purple button on the drive bay to release the drive bay lever and pull it out until it is fully open.

10. With the handle of the drive fully extended, use the purple button to push the drive all the way into the empty slot. This will cause the lever to close part way. Push the lever all the

way inward to lock the drive bay into place as shown in Figure 11.

11. Now that the new drive is installed, you need to add it to the RAID 1 pair by running the

CLI command request system raid add <drive>. For example, if drive A2 failed in the A1/A2 RAID pair, you would run request system raid add A2.

12. To check the status of the new drive, run request system raid detail. In this example, drive A2 shows spare rebuilding as shown in the following output:

Disk Pair A Available

Status clean, degraded

Disk id A1 Present
