•
Missing (MIS)
– The drive was part of a logical drive or was a hot spare drive,
and it is missing. It has been removed or is not responding.
•
Standby (SBY)
– The device is not a hard disk device.
•
Out of Sync (OSY)
– The drive, which is part of a logical drive, is not in sync with
other drives that are part of the logical drive.
•
Degraded (DGD)
– The drive is part of a logical drive and is in degraded state.
•
Rebuilding (RBLD)
– The drive is part of a logical drive and is currently
rebuilding.
•
Optimal (OPT)
– The drive is optimal and is part of a logical drive.
Physical device Drive Type values are as follows:
•
SAS_HDD
– The drive is a SAS hard-disk drive (HDD).
•
SATA_HDD
– The drive is a SATA hard-disk drive (HDD).
•
SAS_SSD
– The drive is a SAS solid-state drive (SSD).
•
SATA_SSD
– The drive is a SATA solid-state drive (SSD).
Physical device Protocol values are as follows:
•
SAS
– The drive supports SAS protocol.
•
SATA
– The drive supports SATA protocol.
HOTSPARE Command
The HOTSPARE command adds a hot spare drive to spare pool 0 or deletes a hot spare
drive. The capacity of the hot spare drive must be greater than or equal to the capacity
of the smallest drive in the RAID volume. You can verify this by using the DISPLAY
command on the drive.
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 only , 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 a solid-state drive hot spare to a volume with hard-disk drives, or
vice versa.
