Checks for an Unknown sparing algorithm. For example, when it has not 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 drive enclosure (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 Enclosure (cage) is
not working, all drives in the cage have a state of Degraded due to the nonredundant condition. Use
commands such as showpd, showpd -s, showcage, showcage -d.
