Replacing, moving, or adding hard drives 38

Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. The

rebuild process automatically restarts.

3. When the rebuild process has finished, replace the newly failed drive.

However, if the newly failed drive has not recovered:

1. Remove the drive that was originally to be replaced, and reinsert the replacement physical drive.

2. Replace the newly failed drive.

3. Restore data from backup.

Upgrading hard drive capacity

You can increase the storage capacity on a system even if there are no available drive bays by swapping

drives one at a time for higher capacity drives. This method is viable as long as a fault-tolerance method

is running.

CAUTION: Because it can take up to 15 minutes per gigabyte to rebuild the data in the new

configuration, the system is unprotected against drive failure for many hours while a given

drive is upgraded. Perform drive capacity upgrades only during periods of minimal system

activity.

To upgrade hard drive capacity:

1. Back up all data.

2. Replace any drive. The data on the new drive is re-created from redundant information on the

remaining drives.

CAUTION: Do not replace any other drive until data rebuild on this drive is complete.

When data rebuild on the new drive is complete, the Online/Activity LED stops flashing steadily and

either flashes irregularly or glows steadily.

3. Repeat the previous step for the other drives in the array, one at a time.

When you have replaced all drives, you can use the extra capacity to either create new logical drives or

extend existing logical drives. For more information about these procedures, refer to the HP Array

Configuration Utility User Guide.

Moving drives and arrays

You can move drives to other ID positions on the same array controller. You can also move a complete

array from one controller to another, even if the controllers are on different servers.

Before you move drives:

• The server must be powered down.

• If moving the drives to a different server, the new server must have enough empty bays to

accommodate all the drives simultaneously.

• The array must not have failed or missing drives.

• No spare drive in the array is acting as a replacement for a failed drive.
