charray

Parameters

-name new_name_arg

(Optional) Specifies the new name to apply to the array MDisk.

-sparegoal 1-100

(Optional) Sets the number of spares to protect the array members with. The value can be a number between 1 and 100.

Note: This parameter is not applicable for distributed arrays.

-balanced

(Optional) Forces the array to balance and configure the spare goals of the present drives.

-slowwritepriority latency | redundancy

(Optional) Controls array ability to complete write operations that take too long, even if it temporarily compromises redundancy.

The value can be either latency or redundancy:

• latency implies the feature is enabled for normal I/O operations
• redundancy implies the feature is not enabled for normal I/O operations

The default value is latency mode for existing arrays, unless the array is RAID-0 (in which case redundancy mode is required).

Important: Do not change the mode of a RAID-0 array.

Important: An array can cause member drives to become unsynchronized (to preserve response time) if the value is latency. If the value is redundancy, the array cannot cause member drives to become unsynchronized (to preserve time) and I/O performance is impacted.

-rebuildareasgoal 0 | 1 | 2 | 3 | 4

(Optional) Specifies the rebuild areas threshold. The array logs an error when the available rebuild areas drop below this specified threshold. The values are 0, 1, 2, 3, or 4. (If you specify 0, an error is not logged if the system runs out of rebuild areas.)

For distributed RAID-1 arrays, the value for a 2-member drive array is 0 or 0 - 1 for a 3 - 16 member drive array. The values 2 - 4 are not supported on distributed RAID-1 arrays.

Note: This parameter is only applicable for distributed arrays.

mdisk_id | mdisk_name

(Required) Identifies (by ID or user-defined name) which array the MDisk command applies to.
