FastStream process: adding or removing Hot Spares

If a member of a RAID group becomes degraded or faulted, you lose some redundancy in your RAID group until a new member is rebuilt into the RAID group. However, Hot Spare devices may be designated as replacements for faulted devices without intervention by you or a host.

You may set up a pool of Hot Spare devices of different sizes appropriate for your RAID groups.

Hot Spares may be set up by the FastStream automatically depending on your choices during initial setup.

Note

Devices in the Hot Spare pool should be of appropriate size to the RAID group so that smaller devices are not replaced by much larger Hot Spare devices, thus wasting storage capacity.

When the ATTO FastStream detects a faulted device:

The Controller searches the Hot Spare pool for the smallest block device of sufficient size to substitute for the faulted drive.

The FastStream replaces the faulted device with the device from the Hot Spare pool.

The FastStream begins an automatic rebuild of the RAID group(s).

Note

A RAID rebuild may take up to two hours to complete.

1Follow the instructions in Preliminary steps on page 31 and click on the FastStream SC arrow from the Select User Process box.

2Select the Add/Remove Hot Spares button.

3Click Next.

4Select the drive(s) to be added or removed from the Hot Spare pool by clicking on the boxes representing those drives.

5When you have completed your changes, click Commit.

6A warning box appears. In the warning box, verify that you want to complete the configuration by clicking on Yes. Clicking on No ends the procedure without making a change.

7When the process is complete, the Health and Status Monitor screen appears.
