Use the following conventions in command descriptions:
•
Text in italics must be entered exactly as shown on the command line.
•
Text surrounded by
<>
must be replaced with a required parameter.
•
Text surrounded by
[ ]
can be replaced by an optional parameter.
•
Parameters surrounded by
{}
must be entered one or more times, as appropriate for the
command issued.
•
Command line definition characters (
<>
,
[ ]
, and
{}
) cannot be entered on the command
line.
Separate the program name, controller number, command, and parameters fields with the ASCII
space character. The format of the parameters is command specific.
The program return value is returned to the user when the program exits. A value of
0
is returned
if the command is successful. Otherwise, a value of
1
is returned.
Rules for creating IM volumes and hot spare disks
When creating IM volumes and hot spare disks, the following rules apply :
•
All disks that are part of an IM volume or a hot spare for an IM volume must be on the same
SAS controller.
•
IM volumes are supported.
•
Only two IM volumes (plus a global hot spare) per controller can be created.
•
An IM array must have two disks.
•
A hot spare disk cannot be created without at least one IM volume already created.
•
The utility does not allow installing a hot spare disk type different from disk types in the volume.
•
With the
AUTO
command all drives used are the same type as the first available disk found,
and the size is limited to the size of the smallest disk.
CFGGEN Commands
Using the CREATE Command
The
CREATE
command creates IM volumes on the SAS controller. Firmware and hardware limitations
for this family of cards limit the number of configurations that are possible.
Syntax
cfggen <controller #> create <volume type> <size> [qsync] [noprompt]
Parameters
<volume type>
Volume type for the volume to be created. Valid value is IM.
<size>
Size of the IM volume in megabytes, or “MAX” for the maximum size
available.
[qsync]
Quick synchronization of the volume created.
[noprompt]
Eliminates warnings and prompts.
Operation
After a disk is added to an IM volume, its storage capacity might or might not be used, depending
on drive capacity and volume capacity. For example, if you add a 36 GB disk to a volume that
only uses 9 GB of capacity on each disk, the remaining 27 GB of capacity on the disk is unusable.
