About Playback Mode
In this mode, the ACU reads the contents of the specified script file and
creates arrays based on the keywords specified in the script.
The syntax is
ACU /P
<file>
where
file
is the name of the script file. The
file parameter can include a drive, directory, filename, and extension. If
no drive or directory is specified, the file is placed in the same location
as the ACU executable.
Note:
The script file syntax allows only one hot spare to be assigned to
an array. Therefore, when recording a RAID 10, the ACU can’t map hot
spares assigned to the individual mirror sets in the resulting script file.
Instead, the ACU creates a single list for all hot spares assigned to the
RAID 10. For more information, see
About Record Mode
Note:
You can also create a script file manually (see
In Record Mode, the ACU writes a RAID controller’s existing array
configuration to a specified script file, which lets you create the same
configuration by running the ACU in Playback Mode (/P switch) with
the resulting script.
You can only record one RAID controller at a time with Record Mode.
Record multiple RAID controllers separately using separate script files.
The syntax is
ACU /R
<file>
where
file
is the name of the script file. The
file parameter can include a drive, directory, filename, and extension,
but only the filename and extension are required. If no drive or directory
is specified, the file is placed in the same location as the ACU executable.
The ACU supports only a subset of available array types. If it encounters
an array it can’t create, a warning displays (or is recorded in the log file,
if the /L switch is used); no keywords for that array are recorded in its
script file.
When recording an array, the ACU always uses the default Wait setting
(equivalent to
Wait=Yes
) unless you edit the script file and include
Wait=No
in the array’s definition block. For more information, see
