in an IM. You can specify a hot spare at array creation, or after
creation, if the array uses five disks or fewer. This field is grayed out
under the following conditions:
• The device does not meet the minimum requirements for use in an
IM array.
• The array has a hot spare.
• The array is made up of the maximum number of devices (six).
• The device isn't large enough to mirror existing data on the
primary. The hot spare drive must be greater than or equal to the
size of any drive in an IM volume.
Drive Status Disk is online and fully functional.OK
Missing Disk is not responding.
Failed Disk has failed.
Initializing Disk is initializing.
CfgOffln Disk is offline at host's request.
User Fail Disk is marked failed at host's request.
Offline Disk is offline for some other reason.
Inactive Disk has been set to inactive.
Not Syncd Data on disk is not synchronized with the rest of
the array.
Primary Disk is the primary disk for a two disk mirror and
is OK.
Secondary Disk is the secondary disk for a two disk mirror
and is OK.
Wrg Type Device is not compatible for use as part of an IM
array.
Too Small Disk is too small to mirror data.
Max Dsks Maximum number of disks allowed for this type
of array has been reached, or maximum number
of total IM disks on a controller has been reached.
No SMART Disk doesn't support SMART and cannot be used
in an RAID array.
Wrg Intfc Device interface (SAS) differs from existing IM
disks.
Pred Fail Indicates whether device SMART is predicting device failure (Yes, No).
Size(MB) Indicates the size of the device in megabytes (megabyte = 1024 x
1024 = 1,048,576 bytes). If the device is part of a two-disk array,
this field reflects the size of the array, not the size of the disk. If the
device is part of a three or more disk array, this field is the size of the
disk within the array.
When creating a striped array, the usable size of the array is
determined by the number of drives multiplied by the size of the smallest
drive in the array. In arrays consisting of different sized drives, excess
space on larger drives is unusable.
