The following information is displayed: Column ID Cage Cage Location Position Device Type Device Protocol Device RPM Description Physical disk ID, as assigned by the system. Physical disks are numbered contiguously during system installation beginning with 0. The drive cage in which the disk resides. A description of the physical location of the drive cage. Location of the disk in Cage:Magazine:Disk format. Indicates whether a physical disk is a Fast Class (FC), Nearline (NL), or Solid State (SSD) drive. The protocol used by the device, e.g., FC or Serial Attached SCSI (SAS). Speed of the specified disk. (RPM) NOTE: The Device RPM 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 Total Capacity Volumes Spares Free Unavailable Failed State of the disk as identified by the kernel. Total amount of usable storage for this disk drive. Amount of storage on the physical disk being utilized by volumes. Amount of storage allocated as spares by the physical disk. Amount of free space on the physical disk, regardless of initialized or not. Amount of unavailable space on the physical disk. Amount of failed space on the physical disk.
