The following information is displayed:
Column Description
ID
Physical disk ID, as assigned by the system. Physical disks are
numbered contiguously during system installation beginning with
0.
Cage The drive cage in which the disk resides.
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 Chunklets
Number of chunklets on the physical disk, excluding those
reserved by the system, such as for the TOC.
Normal Used OK
Number of chunklets allocated to logical disks and containing data
that is currently accessible to the system.
Normal Used Failed
Number of chunklets allocated to logical disks and containing data
but currently inaccessible because they have failed.
Normal Unused Free
Number of chunklets currently free and available for use by logical
disks.
Normal Unused Init
Number of chunklets being cleaned. A chunklet that is clean has
been set to all zeros, and therefore does not contain any data.
Normal Unused
Unavailable
Number of unavailable chunklets.
Normal Unused
Failed Number of initialized but unallocated chunklets that do not contain
data and have failed.
Spare Used OK
Number of chunklets currently used for sparing and containing
data that is accessible by the system.
Spare Used Failed
Number of chunklets used for sparing but containing data that is
currently inaccessible to the system because they have failed.
