Property Definition
You may also want to review the alert log to see whether the physical disk or device 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 that is being an operation is that is being
performed on the physical disk or device.
Encryption Capable Displays whether the physical disk or device is a Self-Encryption Disk (SED). The
possible values are Yes and No.
Encrypted Displays whether the physical disk or device is encrypted to the controller. The possible
values are Yes and No. For a non-SED, the value is N/A.
Bus Protocol Displays the technology that the physical disk or device is using. Possible values are:
• SAS
• SATA
Device Protocol Displays the device protocol of the physical device, such as Non-Volatile Memory
Express (NVMe).
Media Displays the media type of the physical disk or device. The possible values are:
• HDD — Hard Disk Drive. An HDD is a nonvolatile 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 or device.
Remaining Rated Write Endurance Displays information on the SSD renewal/replacement based on the amount of write
workloads. This field indicates the total remaining programs or erase-cycles available on
the SSD, based on the cumulative specification of the total NAND (Negated AND or
NOT AND) Flash chips in the SSD.
NOTE: This option is applicable to Micron PCIe SSDs, Non-Volatile Memory
Express (NVMe) PCIe SSDs, and SAS/SATA SSDs.
Used RAID Disk Space Displays the physical disk or device space that is used by the virtual disks on the
controller. This property is Not Applicable for physical disks or devices attached to
non-RAID controllers.
In certain circumstances, the Used RAID Disk Space displays a value of zero even
though a portion of the physical disk or device is being used. This occurs when the used
space is 0.005GB or less. The algorithm for calculating the used disk space rounds a
figure of 0.005GB or less to 0. Used disk space that is between 0.006GB and 0.009GB
is rounded up 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.
Vendor ID Displays the hardware vendor of the disk.
