Users Guide
The following table describes properties that may be displayed for physical disks depending on the controller.
Property
Definition
Status
These icons represent the severity or health of the storage component.
Normal/OK
Warning/Non-critical
Critical/Fatal
See "Storage Component Severity" for more information.
Name
This property displays the name of the physical disk. The name is comprised of the connector number followed by the disk number.
State
This property displays the current state of the physical disk.
Ready — The physical disk 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 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 has encountered a failure and is operating in a degraded state.
Failed — The physical disk has encountered a failure and is no longer functioning. This state is also displayed when a physical disk 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 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 cannot be recovered. See "Considerations for PERC 3/Si, 3/Di,
CERC SATA1.5/6ch, and CERC SATA1.5/2s Controllers When Physical Disks are Shared by Redundant and Nonredundant 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.
Rebuilding — Data from a redundant virtual disk is currently being rebuilt onto the physical disk.
Incompatible — The physical disk is not suitable for a rebuild. The physical disk may be too small or it may be using an incompatible
technology. For example, you cannot rebuild a SAS disk with a SATA disk or a SATA disk with a SAS disk.
Removed — The physical disk has been removed. This state only applies to physical disks that are part of a virtual disk.
Clear — The Clear task is being performed on the physical disk. A physical disk may also display the Clear state if the physical disk is a
member of a virtual disk that is being slow initialized. For more information, see "Clear Physical Disk and Cancel Clear" and "Format and
Initialize; Slow and Fast Initialize."
SMART Alert Detected — A SMART alert (predictive failure) has been detected on the physical disk. The physical disk may fail and should be
replaced. This state applies to physical disks attached to non-RAID controllers.
Unknown — The physical disk has failed or is in an unusable state. In some cases the physical disk can be returned to a usable state by
performing an "Initialize" task. If the "Initialize" task does not appear on the physical disk drop-down menu, then this disk cannot be
recovered.
Foreign — The physical disk has been moved from another controller and contains all or some portion of a virtual disk (foreign
configuration). A physical disk that has lost communication with the controller due to a power loss, faulty cable or other failure event may
also display the Foreign state. See "Foreign Configuration Operations" for more information.
Unsupported — The physical disk is using an unsupported technology. The physical disk cannot be managed by Storage Management.
Replacing — A Replace Member Disk task is being performed on the physical disk. For more information, see "Replace Member Disk" and
"Revertible Hot Spare."
NOTE: You can cancel the copying of data at any time during the execution of this task.
Capacity
This property displays the full capacity of the disk.
Failure
Predicted
This property displays whether or not the physical disk has received a SMART alert and is therefore predicted to fail. For more information
on SMART predictive failure analysis, see "Monitoring Disk Reliability on RAID Controllers." For information on replacing the physical disk, see
"Replacing a Physical Disk Receiving SMART Alerts."
You may also want to review the Alert Log to see whether the physical disk has generated alerts pertaining to a SMART predictive failure.
These alerts can assist you in identifying the cause of the SMART alert. The following alerts may be generated in response to a SMART
alert:
"2094"
"2106"
"2107"
"2108"
