Position Location of the disk in the format: N:S:P (Node:Slot:Port).
Device Type
Indicates whether a physical disk is a Fibre Channel (FC), Nearline
(NL), or Solid State (SSD) drive.
Device Speed Speed of the specified disk. (RPM)
Note: The Device Speed number does not represent a rotational speed for the drives
without spinning media (SSD). 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
State of the disk as identified by the kernel. See Error! Hyperlink
reference not valid..
Total Capacity Total amount of usable storage for this disk drive.
Volumes Amount of storage on the physical disk being utilized by volumes.
Spares Amount of storage allocated as spares by the physical disk.
