perccli /cx show all
This command shows all controller information, which includes basic controller information, bus information, controller status,
advanced software options, controller policies, controller defaults, controller capabilities, scheduled tasks, miscellaneous
properties, foreign configurations, drive groups, virtual drives, physical drives, enclosures, and BBU information.
Input example:
perccli /c0 show all
NOTE: The PCI information displayed as a part of perccli /cx show and perccli /cx show all commands is not
applicable for the FreeBSD operating system. Hence, the PCI information fields are displayed as N/A.
perccli /cx show freespace
This command shows the usable free space on all disk groups in the controller.
Input example:
perccli /c0 show freespace

Rebuild Rate
perccli /cx set rebuildrate=<value>
perccli /cx show rebuildrate
The detailed description for each command follows.
perccli /cx set rebuildrate=<value>
This command sets the rebuild task rate of the specified controller. The input value is in percentage.
Input example:
perccli /c0 set rebuildrate=30
NOTE: A high rebuild rate slows down I/O processing.
perccli /cx show rebuildrate
This command shows the current rebuild task rate of the specified controller in percentage.
Input example:
perccli /c0 show rebuildrate
Patrol Read
The PERC Command Line Tool supports the following patrol read commands:
perccli /cx resume patrolread
perccli /cx set patrolread ={{on mode=<auto|manual>}|{off}}
perccli /cx set patrolread [starttime=<yyyy/mm/dd hh>] [maxconcurrentpd=<value>]
[includessds=<on|off>] [uncfgareas=<on|off>] [excludevd=x-y,z | none]
perccli /cx set patrolread delay=<value>
perccli /cx show patrolread
perccli /cx start patrolread
