HP 3PAR Operating System Software - Manual (Page 338)

The following information is displayed:
Description Column
Physical disk ID, as assigned by the system. Physical disks are numbered
contiguously during system installation beginning with 0. ID
The drive cage in which the disk is located. Cage
A description of the physical location of the drive cage. Cage Location
Location of the disk in (Cage:Magazine:Disk format. Position
Indicates whether a physical disk is a Fibre Channel (FC), Nearline (NL), or
Solid State (SSD) drive. Device Type
The protocol used by the device, for example, FC 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
Number of chunklets on the physical disk, excluding those reserved by the
system, such as for the TOC. Total Chunklets
Number of chunklets allocated to logical disks and containing data that is
currently accessible to the system. Normal Used OK
Number of chunklets allocated to logical disks and containing data but currently
inaccessible because they have failed. Normal Used Failed
Number of chunklets currently free and available for use by logical disks. Normal Unused Free
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 Uninit
Number of unavailable chunklets. Normal Unused Unavailable
Number of initialized but unallocated chunklets that do not contain data and
have failed. Normal Unused Failed
Number of chunklets currently used for sparing and containing data that is
accessible by the system. Spare Used OK
Number of chunklets used for sparing but containing data that is currently
inaccessible to the system because they have failed. Spare Used Failed
Number of chunklets currently free and available for use, but only as spares. Spare Unused Free
