CMMVC9304E The command failed because the driveclass does not support the specified number of rebuild areas.

Explanation
The number of rebuild areas is not valid for the drive class. This error can occur when an
attempt is made to expand a thin-provisioned array and to add rebuild areas to the array
simultaneously, which is not supported.

User response
If the error occurred during array creation, retry the command and specify fewer rebuild areas
for the same drive class.

If the error occurred during expansion of a thin-provisioned array, retry the command but do not
attempt to add rebuild areas to the array.
