Specifications

4.6.1 INI

Command: Initialize

Description: Initialize restores the MCS-DR to the initial boot-up state in all

regards except for the system log and the contents of internal stor-

age.

Argument Format: <Flags>

Argument Type and Size Description

Flags (ASCII-256-A) To force re-initialization of the system log, spec-

ify the ﬂag “--flush-log” or “-L”. To force re-

initialization of internal RAID storage, specify the ﬂag

“--flush-data” or “-D”. Field need not be padded

with spaces, and order of ﬂags appearance does not

matter.

4.6.2 REC

Command: Record

Description: This command schedules or initiates a recording of output from

the DP subsystem. Upon successful execution of the REC com-

mand, a tag value will be returned which will uniquely identify

the ﬁle. A ﬁle will have been created on the ﬁle-system which is

large enough to accommodate the recording. If an operation is in

progress which prohibits writing to the disk, the ﬁle creation will

only exist in memory until the disk is available for writing. A re-

quest to shutdown with the SCRAM option before such a ﬁle has

been written to the drive will discard the ﬁle.
