Specifications

4.6.8 FMT
Command: Format
Description: This command formats either internal storage, or an attached ex-
ternal storage device. When formatting an external device, the
operation can require a substantial amount of time, proportional
to the size of the device. To determine whether a format com-
mand completed, poll the OP-INFO MIB entry until it no longer
indicates that an operation is in progress, and then request the
REMOVABLE-DEVICES MIB entry. If the command was suc-
cessful, the available space on the device will reflect the formatted
size. If unsuccessful, the reported size will be 0.
Argument Format: <Storage ID>optional
Argument Type and Size Description
Storage ID (ASCII-64-A) Optional argument specifying an external storage de-
vice’s partition. If omitted, the command will format
internal storage. In both cases, it is a destructive oper-
ation and all data on the target is erased. Formatting
unpartitioned devices is not supported, though it may
be in the future.
4.6.9 DWN
Command: Down (internal storage)
Description: This command prepares the MCS-DR’s internal storage for re-
moval/replacement. The command is executed immediately, but
requires as much as 120 seconds to complete. Storage device must
not be disconnected until a TOTAL-STORAGE request returns 0
as data may be lost.
4.6.10 UP
Command: Up (internal storage)
Description: This command brings internal storage back online, and reports the
amount of free space if successful. If the MCS-DR cannot determine
necessary file system information, no destructive changes will be
made. To override this behavior and force a drive initialization,
specify “-F” as an argument. Otherwise, this command has no
arguments.
Response Format: <Available>
Response Element Type and Size Description
Available (ASCII-15-#) Total size of unused portion of internal storage in
bytes. This numb er does not reflect the number of
bytes unavailable due to formatting and file system
usage.
