Observe the following rules when creating hot spare disks:
You cannot create a hot spare disk unless at least one RAID1, RAID10, or RAID1E
volume already exists.
You cannot create a hot spare and add it to an inactive Integrated RAID volume.
For hard-disk drives, you cannot add a SAS hot spare disk if the existing volumes on
the controller use SATA disks. You cannot add a SATA hot spare disk if the existing
volumes on the controller use SAS disks.
For solid-state drives, you can add a SAS hot spare SSD to a volume with SATA SSDs
and you can add a SATA hot spare SSD to a volume with SAS SSDs, if the Integrated
RAID firmware allows it. This depends on the values in the static fields in
Manufacturing Page 4. For more information, see the Fusion-MPT 2.0 MPI
Specification Guide.
The maximum allowable number of hot spare drives depends on the value of the
MaxGlobalHotSpares field in IOC Page 6. (Normally, the maximum is two global hot
spares per controller.)
You cannot add an SSD hot spare to a volume that has HDDs, or vice versa.
Command Line sas2ircu <controller_#> hotspare [delete] <Enclosure:Bay>
Parameters <controller_#> – The index of the controller on which you want to create the
hot spare disk.
<Enclosure:Bay> – The Enclosure:Bay value for the hot spare disk drive. You can
get these values from the output of the DISPLAY command. DOS does not support
addressing by Enclosure:Bay.
delete – This optional command deletes the hot spare disk at enclosure:bay.
Program Return Value 0x00 SUCCESS: Command completed successfully.
0x01 FAILURE: Bad command-line arguments or operational failure.
0x02 ADAPTER_NOT_FOUND: Cannot find specified adapter.
A.3.6 STATUS Command The STATUS command displays the current status of any existing Integrated RAID
volumes and the status of any operation that is currently in progress on the selected
controller. If an operation is not in progress, the SAS2IRCU prints a message indicating
this condition before it exits.
Command Line sas2ircu <controller_#> status
Parameters <controller_#> – The index of the controller with the volumes whose status
you want to display.
