Displaying Inventory Information

To view physical disk inventory information, select Inventory from the filtering list.

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 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

The World Wide Name assigned to the disk.

WWN

Name of the disk manufacturer (for example, SEAGATE).

Manufacturer

Disk model number.
