For more information, see Storage Component Severity.
Name
This property displays the virtual disk name.
State
This property displays the current status of the virtual disk. Possible values are:
Ready—The virtual disk is functioning normally.
Degraded—A physical disk in a redundant virtual disk is not online.
Resynching—A consistency check is being performed on the virtual disk.
On the CERC SATA1.5/6ch controllers, reconfiguring a concatenated virtual disk to a RAID 1 may cause the virtual disk to be in Resynching
state. Performing a Cancel Check Consistency on a virtual disk while it is in Resynching state causes the virtual disk to be in a Failed
Redundancy state. For more information, see Considerations for Concatenated to RAID 1 Reconfiguration on CERC SATA1.5/6ch Controllers.
Resynching Paused—A consistency check has been paused on the virtual disk.
Regenerating—A physical disk in the virtual disk is rebuilding.
Reconstructing—The virtual disk configuration has changed. The physical disks included in the virtual disk are being modified to support the
new configuration.
Failed—The virtual disk has encountered a failure of one or more components and is no longer functioning.
Failed Redundancy—This state is displayed when the initial consistency check for the virtual disk is cancelled or is not successful. This state
may also be displayed when a RAID 1, RAID 10 or RAID 1-concatenated virtual disk suffers a physical disk failure. In addition, there are other
conditions related to disk failures and the firmware that can cause a virtual disk to display a Failed Redundancy state. When a virtual disk is
in Failed Redundancy state, performing a Check Consistency may return the virtual disk to a Ready state. This state only applies to virtual
disks on a CERC SATA1.5/6ch, and CERC SATA1.5/2s controller.
Background Initialization—A background initialization is being performed on the virtual disk.
Formatting—The virtual disk is being formatted. Formatting applies to the CERC SATA1.5/6ch controllers. For more information, see Format
and Initialize; Slow and Fast Initialize.
Initializing—The virtual disk is being initialized. Initialization applies to the PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di controllers. For
more information, see Format and Initialize; Slow and Fast Initialize.
On some controllers, the virtual disk state is not updated until the controller performs an I/O operation. For more information, see I/O and
Reboot Requirements for Detecting Physical Disk Status Changes.
Degraded Redundancy—This state is applicable to RAID 6 only in which a physical disk in a redundant virtual disk is not online, but the virtual
disk is still accessible and functioning.
Virtual Disk
Bad Block
This property displays whether the virtual disk has bad blocks.
Encrypted
This property displays whether the virtual disk is encrypted. The possible values are Yes and No.
Hot Spare
Policy
Violated
This property displays whether the Hot Spare Protection Policy has been violated.
NOTE: This property is displayed only if you set any Hot Spare Protection Policy. For more information, see Setting Hot Spare Protection
Policy.
Layout
This property displays the RAID level.
Size
This property displays the total capacity of the virtual disk.
The algorithm for calculating the virtual disk size rounds a value of 0.005 or less down to 0.00 and a value between 0.006 and 0.009 up to
0.01. For example, a virtual disk size of 819.725 is rounded down to 819.72. A virtual disk size of 819.726 is rounded up to 819.73.
Device Name
This property displays the operating system device name for this object.
Bus Protocol
This property displays the technology that the physical disks included in the virtual disk are using. Possible values are:
SCSI—Small Computer System Interface
SAS—Serial Attached SCSI
SATA—Serial Advanced Technology Attachment (SATA)
Media
This property displays the media type of the physical disks present in the virtual disk. The possible values are:
HDD—Hard Disk Drive. A HDD is a non-volatile storage device which stores digitally-encoded data on rapidly rotating platters with magnetic
surfaces.
SSD—Solid State Drive. An SSD is a data storage device that uses solid-state memory to store persistent data.
