Physical Disk Or Physical Device Properties
Property | Definition |
Status | These icons represent the severity or health of the storage component.
|
Power Status | Displays the power status of the physical drives. The power status is present only for H700 and H800 controllers and is not present in the Physical Disk for Virtual Disk page.
NOTE: Power status of SAS/SATA SSD showing as
Not Applicable is an expected behaviour in Storage Management.
|
Spun Down | Indicates that the physical drive is in spun down state. Only hot spare and unconfigured disk can be in spun down state if there is no activity on the drives for a specified interval of time. |
Transition | Indicates that the physical drive is changing from the spun down state to spun up state. |
Spun Up | Indicates that the physical drive is in the spun up state. |
Name | Displays the name of the physical disk or device. The name includes of the connector number followed by the disk number.
For all the disks which are not part of the virtual disk will display as NON-Raid Disks for systems running on Enhanced HBA mode. Hot-plugged in disks also displays as NON-RAID disks. |
State | Displays the current state of the physical disk or device. Possible values are:
You can perform the following tasks on the Non-RAID disks:
You cannot perform the following tasks on the disk:
|
Certified | Displays whether the physical disk or device is certified by your service provider. |
Mirror Set ID | Displays the mirror set ID of the member physical disk or device that has duplicated data from another physical disk or device. |
Capacity | Displays the capacity of the disk. |
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:
|
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:
|
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:
|
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. |
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. |
Product ID | Displays the product ID of the device. |
Firmware Revision | Displays the firmware version of the physical device. |
Serial No. | Displays the serial number of the disk. |
Part Number | Displays the Piece Part Identification (PPID) of the physical drive. |
T10 Protection Information Capability | Indicates whether the physical disk supports data integrity. The possible values are Yes and No. |
Sector Size | Displays the sector size of the physical disk. The possible options are 512B and 4KB. |
PCIe Negotiated Link Speed | Displays the current negotiated transfer speed of the physical device in GT/s. |
PCIe Maximum Link Speed | Displays the capable transfer speed of the physical device in GT/s. |
Manufacture Day | Displays the day of the month when the physical disk was manufactured. |
Manufacture Week | Displays the week of the year when the physical disk was manufactured. |
Manufacture Year | Displays the year when the physical disk was manufactured. |
SAS Address | Displays the SAS address of the physical disk. The SAS address is unique to each SAS disk. |
PCIe Negotiated Link Width | Displays the current negotiated link width of the physical device. |
PCIe Maximum Link Width | Displays the capable link width of the physical device. |
Non-RAID Disk cache policy | Displays the cache policy of the NON-RAID disk. For the Non-RAID physical disk the Non-RAID disk cache policy property can be changed to unchanged, enable, or disable.
NOTE: This feature is not available from PERC 10 or later.
|
Available Spare | Displays the available spare value set for all SSDs (SAS / SATA). New disk will have 100% spare which comes down as per the usage. |
Cryptographic Erase Capable | Displays yes if the cryptographic erase or sanitize cryptographic erase is supported or not. |
