Property Definition
After Import State Displays the after-import state of the physical disk. The physical disk can be imported in any of the
following states:
• Online — The physical disk is part of the imported virtual disk and functions normally.
• Offline — The physical disk is offline after import to the virtual disk.
• Foreign — The virtual disk containing the physical disk cannot be imported and the physical
disk remains in foreign state.
• Rebuild — After import of virtual disk, the physical disk rebuilds.
• Replacing — A Replace Member Disk task is performed on the physical disk. For more
information on replacing a member disk, see Replacing A Member Disk and Enabling Revertible
Hot Spare.
Capacity Displays the capacity of the disk.
Failure Predicted Displays whether the physical disk has received a Self-Monitoring Analysis and Reporting
Technology (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
• 2109
• 2110
• 2111
For information on alert messages, see the Server Administrator Messages Reference Guide.
Progress Displays the progress of an operation being performed on the physical disk.
Bus Protocol Displays the technology that the physical disk is using. Possible values are:
• SAS — Serial Attached SCSI
• SATA — Serial Advanced Technology Attachment
Device Protocol Displays the device protocol of the physical device, such as Non-Volatile Memory Express (NVMe).
Certified Indicates that the drive has firmware which has been tested and fully qualified by the service
provider. Drives that are not certified by the service provider may work but, are not supported and
recommended for use in servers.
Media Displays the media type of the physical disk. The possible values are:
• HDD — Hard Disk Drive. An 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.
• Unknown — Storage Management is unable to determine the media type of the physical disk.
Used RAID Disk Space Displays the amount of the physical disk space that is used by the virtual disks on the controller.
This property is not applicable for physical disks attached to non-RAID controllers.
In certain circumstances, the Used RAID Disk Space displays a value of zero (0) even though a
portion of the physical disk is actually being used. This occurs when the used space is 0.005GB or
less. The algorithm for calculating the used disk space rounds off a figure of 0.005GB or less than
zero. Used disk space that is between 0.006GB and 0.009GB is rounded off to 0.01GB.
Available RAID Disk Space Displays the amount of available space on the disk. This property is not applicable for physical disks
attached to non-RAID controllers.
Hot Spare Indicates whether the disk has been assigned as a hot spare. This property is not applicable for
physical disks attached to non-RAID controllers.
