- PDG No.
Type the RANK to be expanded and number of the PD group to which the PD belongs.
- RANK No.
Type the number of the RANK to be expanded.
* The RANK capacity can be expanded only for the RANK of which RAID type is 5.
- PDN
Type the number of a disk to be added to the RANK.
- Expansion Time
Specify a RANK expansion time. As the numeric value is lower, the expansion priority level gets higher;
oppositely, as the numeric value is greater, the expansion priority level gets lower. When 0 is specified,
however, expansion is performed preferentially.
* Be sure to confirm the disk configuration by selecting "0. View Current Settings" on the menu before executing
the RANK capacity expansion.
* When expanding multiple PDs, execute RANK capacity expansion for each PD. In this case, confirm that a
PD is expanded normally, then expand the next one.
