How to determine when it is safe to remove a multi-disk carrier

Removing a multi-disk carrier before it is safe to do so can result in one or more RAID groups becoming degraded, or possibly even a storage disruption. System Manager enables you to determine when it is safe to remove a multi-disk carrier.

When a multi-disk carrier has to be replaced, the following events must have occurred before you can remove the carrier safely:

An AutoSupport message must have been logged indicating that the carrier is ready to be removed.
An EMS message must have been logged indicating that the carrier is ready to be removed.
The state of both disks in the carrier must be displayed as broken in the Disks window.
You must remove the disks only after the carrier mate of a failed disk is evacuated. You can click Details to view the disk evacuation status in the Properties tab of the Disks window.
The fault LED (amber) on the carrier must be lit continuously indicating that it is ready for removal.
The activity LED (green) must be turned off indicating there is no disk activity.
The shelf digital display only shows the shelf ID number.

Attention: You cannot reuse the carrier mate of a failed disk. When you remove a multi-disk carrier that contains a failed disk, you must replace it with a new carrier.
