pd
Displays Physical Drives (PDs) with states or conditions that are not optimal:
Checks for failed and degraded PDs
Checks for an imbalance of PD ports, for example, if Port-A is used on more drives than Port-B
Checks for an Unknown Sparing Algorithm. For example, when it hasn't been set
Checks for drives experiencing a high number of IOPS
Reports if a servicemag operation is outstanding (servicemag status)
Reports if there are PDs that do not have entries in the firmware DB file
Reports PDs with slow SAS connections
Reports minimum number of PDs in a cage and behind a node pair
Reports PDs that are not admitted to the system

pd Suggested Action 1

Both degraded and failed drives show up in this report. When an FC path to a drive cage is not
working, all drives in the cage have a state of Degraded due to the non-redundant condition. Use
commands such as showpd, showpd -s, showcage, showcage -d.
