194 Physical Disks or Physical Devices
State This property displays the current state of the physical disk or
device.
Ready—The physical disk or device is functioning normally. If
the disk is attached to a RAID controller, Ready state
indicates that the disk is available to be used by a virtual disk.
When the physical disk or device is used in a virtual disk, the
state changes to Online.
Online—The physical disk is part of a virtual disk and is
functioning normally. See Online and Offline for more
information.
Degraded—The physical disk or device has encountered a
failure and is operating in a degraded state.
Failed—The physical disk or device has encountered a failure
and is no longer functioning. This state is also displayed when
a physical disk or device that is part of a redundant virtual disk
has been taken offline or deactivated. See Online and Offline
for more information.
Offline—The physical disk or device has failed or contains
dead segments. Check to see whether the Remove Dead
Segments task appears on the physical disk drop-down menu.
If it does, perform a Rescan Controller and then do a Remove
Dead Segments for the physical disk. If the Remove Dead
Segments task is not displayed, then the physical disk or
device cannot be recovered. See Considerations for CERC
SATA1.5/6ch and CERC SATA1.5/2s Controllers When
Physical Disks are Shared by Redundant and Non-Redundant
Virtual Disks for related information.
On the PERC 5/E controller, the Offline state indicates that
the disk is included in a virtual disk, but it is not receiving I/O.
This may occur when a user has set the disk to Offline. See
Online and Offline for more information.
