Chapter 7 Disk Array Configuration Setting
(S400/S1400/S2400/S2800)
This chapter describes how to set the configuration of the disk array in S400/S1400/S2400/S2800. For configuration setting in
S100/S1100/S1200/S1300/S2100/S2200/S2300, refer to Chapter 8.

Specify the physical disks of the disk array to be put in the RAID configuration and assign the RAID type to bind a
pool. Then, bind the logical disks to the pool to bind the logical disks. In addition, bind a control volume
individually. A control volume is a volume for control over snapshot operation. (For the details of control volumes,
refer to "Snapshot User’s Manual (Function Guide)" (IS030).)
After adding physical disks, take the steps stated above to the added physical disks to bind the logical disks. Adding
physical disks puts no influence on any existing logical disks, which belongs to the pool and already in use. Adding
and binding logical disks to the pool also puts no influence on any existing logical disks.
Pools are classified into two types; the dynamic pool allows expanding the capacity of the pool and the logical disks,
and the basic pool does not allow expanding the capacity of the pool and the logical disks.
The logical disk configurations selectable by the pool are as follows:
Logical disk configuration: Dynamic pool RAID6 (4+PQ)/(8+PQ)
Basic pool RAID1 (1+1)
Basic pool RAID5 (4+P)
Basic pool RAID10 (1+1) × 2/(1+1) × 4/(1+1) x 8
Basic pool RAID50 (4+P) × 2/(4+P) × 4
Bind logical disks in accordance with the following procedure.
(1) Pool Bind
(2) LD Bind
