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 with a new carrier.
For more information about how to determine when it is safe to remove a faulted disk carrier, see the hardware guide for your disk shelf model on the NetApp Support Site.
