■ Type. Device type of the PD.
◆ FC - Fibre Channel
◆ NL - Nearline
◆ SSD - Solid State Drive
■ Speed(K). The maximum RPM speed of the physical disk. The 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 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 PD can be one of the following:
◆ normal - PD is normal
◆ degraded - The PD is not operating normally. Use showpd -s to find out the detail
information.
◆ new - The PD is new, needs to be admitted before it can be used (see help admitpd)
◆ failed - The PD has failed.
■ Total. Total size of the disk in MB (1024^2 bytes).
■ Free. Free size of the disk in MB (1024^2 bytes). This includes the size that is available to
use, uninitialized, and unavailable to use.
■ Port_A. The port location for the A port of the physical disk. If the primary path, the port
location is followed by an asterisk (

dash (

■ Port_B. The port location for the B port of the physical disk. If the primary path, the port
location is followed by an asterisk (
