Operating System Software Instruction Manual

DescriptionColumn
A description of the physical location of the drive cage.Cage Location
Location of the disk in the format in Cage:Magazine:Disk format.Position
Indicates whether a physical disk is a Fast Class (FC), Nearline (NL), or Solid
State (SSD) drive.
Device Type
The protocol used by the device, for example, FC or SAS.Device Protocol
Speed of the specified disk (in thousands of RPMs).Device RPM
NOTE: The Device RPM number does not represent a rotational speed for the drives without spinning media (SSDs).
It is meant as a rough estimation of the performance difference between the drive and the other drives in the system.
For FC and NL drives, the number corresponds to both a performance measure and actual rotational speed. For an
SSD drive, the number is to be treated as relative performance benchmark that takes into account in I/O per second,
bandwidth, and the access time.
State of the disk as identified by the kernel.State
Description of the disk state.State Description
State of self-encrypting disks. The state will be one of the following:SED State
Unknown – SED state information is not yet available.
Not Capable – The drive does not have SED capability (encryption can only
enabled on SED drives).
Capable – The drive is SED capable but the system has not yet taken ownership
of the drive.
Owned – The system has ownership of the drive.
Owned by a Different System – The drive is owned by another system where
encryption was enabled, or the selected system might have had all nodes
replaced and the serial number not yet set.
Total amount of usable storage for this disk drive.Total Capacity
Amount of free space (in GiB) in the disk drive, regardless of initialized or not.Free Capacity
Amount of storage remaining (in GiB) for use on the disk drive.Allocated Capacity
Amount of storage (%) consumed by the disk drive.Allocated Percentage
Location of the primary initiator port to which the disk is attached, in
Node:Slot:Port format.
Port A
Location of the secondary initiator port to which the disk is attached, in
Node:Slot:Port format.
Port B

Number of used chunklets with data that is accessible to the system.Normal Used OK
Number of used chunklets that have failed.Normal Used Failed
Number of initialized but currently unused chunklets available for use by logical
disks.
Normal Unused Free
Number of chunklets being cleaned.Normal Unused Uninit
Number of chunklets that are unavailable for use.Normal Unused Unavailable
