This task causes the lights on the disk to blink. You can safely remove the disk under the following conditions:
l Wait for about 30 seconds to allow the disk to spin down.
l Wait until you notice the initial blink pattern has changed into a different pattern or the lights have stopped blinking.
A physical disk is no longer in Ready state after doing a Prepare to Remove. Removing the physical disk from the enclosure or backplane and replacing it
causes the physical disk to spin up and return to Ready state.
In some cases, a rescan is required for the controller to recognize configuration changes such as the removal of a disk. See "Rescan to Update Storage
Configuration Changes" for more information.
Initialize
Does my controller support this feature? See "Supported Features."
The Initialize task prepares a physical disk for use as a member of a virtual disk.
Physical disks attached to PERC 3/Si, 3/Di, and CERC SATA1.5/6ch controllers must be initialized before they can be used. On these controllers, the Initialize
task can only be performed once on a physical disk. In some cases a physical disk that is in an Unknown state can be returned to a usable state by performing
the Initialize task. The Initialize task is not displayed for physical disks that have already been initialized using Storage Management or the BIOS.
Rebuild
Does my controller support this feature? See "Supported Features."
Use the Rebuild task to reconstruct data when a physical disk in a redundant virtual disk fails. See "Replacing a Failed Disk that is Part of a Redundant Virtual
Disk" for more information.
Rebuilding a disk may take several hours.
Cancel Rebuild
Does my controller support this feature? See "Supported Features."
Use the Cancel Rebuild task to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a degraded state. The failure of an
additional physical disk can cause the virtual disk to fail and may result in data loss. It is highly recommended that you rebuild the failed physical disk as soon
as possible.
Assign and Unassign Global Hot Spare
NOTE: This procedure is not available for physical disks that have been assigned as a hot spare or physical disks that are part of a virtual disk. In
addition, this procedure is only supported for hotswap physical disks (disks that reside in a carrier).
NOTE: This procedure is not supported on the CERC ATA100/4ch, CERC SATA1.5/6ch, and CERC SATA1.5/2s controllers. For the PERC 4/IM controller,
thisprocedureisonlysupportedonaPowerEdge™1855system.
CAUTION: This is a data-destructive task. Any virtual disks residing on this physical disk will be removed.
NOTE: If you cancel the rebuild of a physical disk that is assigned as a hot spare, you will need to reinitiate the rebuild on the same physical disk in
order to restore the data. Canceling the rebuild of a physical disk and then assigning another physical disk as a hot spare will not cause the newly
assigned hot spare to rebuild the data. You will need to reinitiate the rebuild on the physical disk that was the original hot spare.
