Summary
The config command has two options: Automatic and Express.
Automatic configuration takes all available unconfigured physical drives to create
an optimized disk array following a default set of parameters. There are no
options.
Express configuration takes your input, creates one or two arrays, and spreads
their capacity evenly over all of the logical drives that you specify.
The redundancy option creates redundant logical drives (RAID 1, 10, 1E, 5, 50,
6, or 60).
The capacity option enables optimizes the logical drives for capacity.
The performance option optimizes the logical drives for performance.
If you choose all three options, redundancy gets highest priority and capacity
gets lowest priority.
Options
-a <action> Specifies the action to perform.
auto Automatic configuration with no options.
Creates an optimized disk array. One or more logical
drives are created automatically.
expr Express configuration. RAID level is dependant on the
options chosen.
-r <y|n> Selects the redundancy option.
-p <y|n> Selects the performance option.
-c <y|n> Selects the capacity option.
-m <y|n> Allows mixing SATA and SAS physical drives in the same
array.
-s <y|n> Includes a spare drive in the array.
Note: Requires 5 or more unconfigured physical drives.
-t <AppType> Specifies the intended application for this array.
video Sequential large block reads.
data Random read/write mix, small to medium sized IO.
log Sequential small block write.
other Random read/write mix, small to medium sized IO.
fileserver Random read/write mix, small to medium sized IO.
-l <num of LDs> Specifies how many logical drives to include in the
configuration. Array capacity is divided evenly among the
logical drives.
