InForm OS Version 2.3.1 Command Line Interface Reference
Relocation of chunklets is considered one step and can take from several minutes to several
hours (depending on number of chunklets) to complete. If
servicemag unmark is issued
during the relocation phase, the spin-down phase will indicate that the
servicemag
start
operation Failed. This can be confirmed by issuing servicemag status -d. If
the intent was to prevent servicemag from completing, issue
servicemag resume to
move the data back onto the drive(s) in this magazine once the
servicemag start
operation reports a failure. The unmark option should not be used without consulting with
3PAR engineering.
status
Specifies that the status of the servicemag command operations on a drive magazine are
displayed.
clearstatus
Clears the log shown by the servicemag command status for the given cage and
magazine.
OPTIONS
–f
Specifies that the command is forced. If this option is not used, the command requires
confirmation before proceeding with its operation.
–wait
Specifies that the servicemag command must be completed before exiting. If not
specified, the
servicemag command automatically exits before service begins and the
remainder of the process proceeds in the background. This option is only valid for the
start or resume operations.
–log
Specifies that write operations to chunklets of valid disks are written to a logging area
when the magazine is out of service (or removed). When the disks return and the
servicemag resume option is issued, the data is written from the logging Logical Disks
(LDs) to those disks. Chunklets are relocated to free or spare space if their failures would
result in a RAID set becoming invalid (for example, if two disks would be missing from a
RAID 5 LD). All other used chunklets are placed in the logging mode. This option is only
valid for the
start operation.
-nodisks
Specifies that the serviced drive magazine’s disk drives are valid and do not need to be
replaced. This option can only be used with the
start subcommand and -log option.
