The Array_Defaults parameter defines
the default values to use for the variance and number of hot-spare
drives when AUTO is specified for Array_Mode.
Description
The Array_Defaults parameter
is not valid if Array_Mode is set to CUSTOM.
The
value of Array_Defaults is expressed in the format: variance:hotspares,
where:
variance specifies the percentage
variance to use when selecting drives to add to the array. This parameter
is useful when you are using drives that may vary slightly in size.
Variance is based on a percentage of the drive's size in MB. Valid
values are:
- 0% Only drives with an equal size in MB are combined
into a single array.
- 5% All drives within 5 percent of the same size
in MB are combined into a single array.
- 10% All drives within 10 percent of the same
size in MB are combined into a single array.
- 100% All drives, regardless of size in MB, are
combined into a single array.
and
hotspares is
an integer that specifies the total number of hot-spare drives to
create. The largest drives are chosen as hot-spare drives first.
If not enough drives are available to create hot-spare drives, then
PRAID does not create any hot-spare drives.
