202 Physical Disks or Physical Devices
A physical disk or physical device is no longer in Ready state after doing a
Prepare to Remove. Removing the physical disk or device from the enclosure
or backplane and replacing it causes the physical disk or device 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 or device. See Rescan to
Update Storage Configuration Changes for more information.
NOTE: This procedure is not available for physical disks or devices that have been
assigned as a hot spare or physical disks or devices that are part of a virtual disk. In
addition, this procedure is only supported for hotswap physical disks or devices
(disks that reside in a carrier).
NOTE: This procedure is not supported on the CERC SATA1.5/6ch, and CERC
SATA1.5/2s controllers. For the PERC 4/IM controller, this procedure is only
supported on a PowerEdge™ 1855 system.
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 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.
CAUTION: This is a data-destructive task. Any virtual disks residing on this
physical disk is removed.
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.
