Table 36. Physical Disk Properties (continued)
Property Definition
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.
NOTE: For NVMe drives the value will be enumerated as NA.
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.
WWN Displays the value for the physical device.
NOTE: RAID 0 virtual disk can create on predictive failure drive using AutoConfigure behavior, but same is not allowed while
creating the virtual disk task.
