The columns in the previous example are identified as follows: • ID. Physical disk ID, as assigned by the system. For unadmitted disk the ID appears as dashes (--). • CagePos. Position of PD, in the format :.: where is the cage number, is 0 or 1 depending on whether the cage is on the left or right (from the front view) of the disk chassis, is the magazine number (0 through 4) and is the disk number (0 through 3) within the magazine. If the position ends with (?) the current position of the drive is not known (for example, the drive may be missing), and the position shown is the last known position. • Type - Device type of the PD. ◦ FC - Fibre Channel. ◦ NL - Nearline. ◦ SSD - Solid State Drive. • RPM. 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 drives, 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 (*). If disabled, the port location is followed by a 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 (*). If disabled, the port location is followed by a dash (-). The following example displays disk information for the nearline disks on cage 0 and sort the output by the cage position: cli% showpd -sortcol 1 -p -cg 0 -devtype NL ---Size(MB)---- ----Ports---- ID CagePos Type RPM State Total Free A B 0 0:0:0 NL 7 degraded 715008 684288 0:0:1* 1:0:1 2 0:4:0 NL 7 degraded 715008 684288 0:0:1 1:0:1* 4 0:8:0 NL 7 degraded 715008 684288 0:0:1* 1:0:1 6 0:12:0 NL 7 degraded 715008 684288 0:0:1 1:0:1* 4 total 2860032 2737152 showpd 429
