This command requires that there is sufficient free memory available for the specified I/O group to allocate the memory that is required for the new array.
Ensure that there is sufficient memory available to the I/O group, and resubmit the command. You can increase the amount of memory that is allocated to the I/O group. You can also reduce the amount of memory that is used by reducing the number VDisk mirrors or Copy Services relationships in the IO Group.
