6. An IME volume can have three to ten disks, as long as rules 4 and
5 are not violated. An IS volume can have two to ten disks.
7. The the total number of disks combined for two volumes cannot
exceed twelve. In addition, one or two hot spare disks can be created
per controller, making a maximum of 14 disks supported per
controller. (Support for this number of disks requires Integrated RAID
firmware v1.20.00 or above.)
Command Line –
cfggen <controller #> auto <volume type> <size>
[qsync] [noprompt]
Parameters –
•
<controller #> – Number of the SAS controller targeted by this
command.
•
<volume type> – Volume type for the volume to be created. Valid
values are IM, IME, and IS.
•
<size> – Size of the RAID volume in megabytes, or MAX for the
maximum size available.
•
[qsync] – If this optional parameter is specified, a quick
synchronization of new volume will be performed. If the volume type
is IME or IS, a quick synchronization is always performed even if this
option is not specified. A quick synchronization means that the first
32-KB of the drives in the volume are cleared to 0.
•
noprompt – Suppresses display of warnings and prompts.
Program Return Value –
0x00 SUCCESS: command completed successfully.
0x01 FAILURE: bad command line arguments or operational failure.
A.3.11 DISABLEIR Command (EFI Version Only)
The DISABLEIR command, which is currently supported only in the EFI
version of CFGGEN, disables Integrated RAID functionality on the
supported SAS controller chips. This is done by setting the
MPI_IOUNITPAGE1_DISABLE_IR bit in the IO Unit 1 MPT Configuration
Page.
