-scan

(Optional) Scans the specified MDisk or drive for system metadata.

-dump

-end end_arg

-file filename_arg

(Required) Specifies the file in which you want the results of a scan operation. The file is placed into the node in the directory /dumps, and can be retrieved using Secure Copy (scp). The file can be subsequently cleaned using the cleardumps command.

-start start_arg

(Required) Specifies the following conditions:
