The disk identified by the first

Enclosure:Bay

on the command line becomes the

primary

disk

drive when you create an Integrated Mirroring (RAID 1) volume.

If the controller

resynchronizes the disk drives, the data on the primary disk drive becomes available

when you access the newly created volume.

When the IR firmware creates a RAID 1 volume, it starts a background initialization

of the volume. You can use the STATUS command to monitor the status of

the initialization.

Observe the following rules when creating Integrated RAID volumes and hot

spare disks:



All disks that are part of a volume, including hot spares for that volume, must be on

the same SAS2 controller.



You can create RAID 0, RAID 1, RAID 1E, and RAID 10 Integrated RAID volumes.



You can create a maximum of two Integrated RAID volumes per controller.



The configuration of the Integrated RAID firmware determines the maximum and

minimum number of drives that you can use in Integrated RAID volumes. The

following fields of IOC Page 6 specify the configuration:

MaxDrivesRAID0, MaxDrivesRAID1, MaxDrivesRAID10, MaxDrivesRAID1E

MinDrivesRAID0, MinDrivesRAID1, MinDrivesRAID10, MinDrivesRAID1E,

MaxVolumes, MaxPhysDisks, MaxGlobalHotSpares, MaxPhysDisks (maximum

number of physical drives combined in

all

volumes on the controller)

For more information, refer to the description of the IOC configuration pages in the

Fusion MPT 2.0 MPI Specification Guide

.



SAS2IRCU does not allow you to create an Integrated RAID volume that combines

SAS and SATA hard disk drives.



SAS2IRCU does not allow you to create an Integrated RAID volume that combines

SSDs (solid-state drives) and hard disk drives.



SAS2IRCU

does

allow you to use both SATA and SAS solid-state drives in a single

Integrated RAID volume, if the Integrated RAID firmware supports it. Support for

such a mixing is specified by values in static fields in Manufacturing Page 4 in the

MPI2 specification and is specific for SSD drives only.

Command Line

sas2ircu <

controller_#

> create <

volume_type

> <

size

>

{<

Enclosure:Bay

>} [

VolumeName

] [noprompt]

Parameters



<

controller_#

>

– The index of the controller for the newly created volume.



<

volume_type

>

– Volume type for the new volume.

Valid values are RAID0,

RAID1, RAID10, or RAID1E.



<

size

>

– Size of the RAID volume in Mbytes, or

MAX

for the maximum size

available.



<

Enclosure:Bay

>

– The Enclosure:Bay value of the disk drive for the new RAID

volume. You can get these values from the output of the DISPLAY command. DOS

does not support addressing by Enclosure:Bay.



VolumeName

–

A user-specified string to identify the volume.



noprompt

– This optional parameter prevents warnings and prompts from

appearing while the command is running.
