Parameters

-delim delimiter
(Optional) Specify a delimiter to separate data in the output.
-nohdr
(Optional) Suppress the headings in the output.
-drivecount 2 - 128
(Required) Specifies the number of the drives. The value must be a number in the range 2 - 128. The value for distributed RAID-1 arrays must be in the range 2 - 16.
-driveclass drive_class_id
(Required) Specifies the drive class. The driveclass_id value must be a number.
-level raid1
| raid6
(Required) Specifies the RAID level for the array that is being created. The possible values are:
  • raid1
  • raid6
-stripewidth 2 - 16
(Required) Indicates the width of a single unit of redundancy within a distributed set of drives. The value must be:
  • RAID-1: 2
  • RAID-6: 5 - 16
-rebuildareas 0 | 1 | 2 | 3 | 4
(Optional) Specifies the number of rebuild areas in the array. This value must be in the range 1 - 4 for RAID-6 arrays.
For distributed RAID-1 arrays, the value must be either 0 or 1 with these restrictions:
  • 0 is valid only if drivecount is 2.
  • 1 is valid only for drivecount values in the range 3 - 16.
-strip 256
(Optional) Specifies sets the strip size in KiB for the array that is being configured. The value is 256.
mdiskgrp_id | mdiskgrp_name
(Required) Indicates the MDisk array ID or name.

Description

This command displays the size of a potential array for a specified drive count, class, and RAID level.

You can use this command to define potential sizes for distributed arrays. (Distributed array descriptions are triggered by using -rebuildareas.) This command assists with the configuration options that are provided during array creation, and estimates the array capacity if it were to be configured
