Displaying Environmental Information
To view physical disks' environmental information, select Environmental 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
Identified correctable read errors. Correctable Read Errors
Identified uncorrectable read errors. Uncorrectable Read Errors
Identified correctable write errors. Correctable Write Errors
Identified uncorrectable write errors. Uncorrectable Write Errors
Internal temperature of the disk. Temperature
