Logical Drive – Hot Spare in Use

What Caused the Problem?

One or more drives have failed, and hot spare drives have automatically taken over for the failed drives. The data on the logical drives is still accessible. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution

Electrostatic discharge can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.

Important Notes

When a hot spare takes over for a failed drive, data from the failed drive is reconstructed on the hot spare. When you replace the failed drive, data is copied back from the hot spare to the new drive and the hot spare returns to Standby. You can replace the failed drive before reconstruction is completed on the hot spare. However, the copyback to the new drive will not occur until the reconstruction has completed.

Look at the logical drive icons for the affected logical drives in the Logical View of the Subsystem Management Window. If any logical drives display an Operation in Progress icon , reconstruction is still taking place on the hot spare. If all logical drive icons are Optimal , reconstruction is completed.

Depending on how many hot spares you have created in the storage subsystem, a logical drive could remain Optimal and still have multiple failed drives (each one being covered by a hot spare).

Make sure the replacement drives have a capacity equal to or greater than the failed drives.

You can replace the failed drives while the affected logical drives are receiving I/O.

Recovery Steps

1

Remove the drive (its fault indicator light should be on).

2

Wait 30 seconds, then insert the new drive. Its fault indicator light may be lit for a short time (one minute or less).

Result: The affected logical drives in the Logical View of the Subsystem Management Window change to an Operation in Progress icon as the reconstruction/copyback operations take place. When reconstruction/copyback is completed, the logical drives return to Optimal , and the hot spare drive returns to
