Rebuild drives commands
The following commands rebuild drives in the PERC Command Line Tool:
perccli /cx[/ex]/sx pause rebuild
perccli /cx[/ex]/sx resume rebuild
perccli /cx[/ex]/sx show rebuild
perccli /cx[/ex]/sx start rebuild
perccli /cx[/ex]/sx stop rebuild
NOTE: If enclosures are used to connect physical drives to the controller, specify the enclosure ID in the command.
The detailed description for each command follows.
perccli /cx[/ex]/sx pause rebuild
This command pauses an ongoing rebuild process. You can run this command only for a drive that is currently being rebuilt.
Input example:
perccli /c0/s4 pause rebuild
perccli /cx[/ex]/sx resume rebuild
This command resumes a paused rebuild process. You can run this command only when a paused rebuild process for the drive
exists.
Input example:
perccli /c0/s4 resume rebuild
perccli /cx[/ex]/sx show rebuild
This command shows the progress of the rebuild process in percentage.
