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
