Table 32. Physical Disk Properties (continued)
Property Definition
Failure Predicted Displays whether the physical disk or device 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 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
NVMe
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, M.2 devices 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.
