Chapter 8 Disk Array Configuration Setting (S100/S1100/S1200/S1300/S2100/S2200/S2300)
IV-123
(2) Execution conditions
When batch binding logical disks for all the physical disks, all the existing settings are unset. Therefore, if any
one of the following conditions is met, the batch binding cannot be executed.
(i) Logical disks managed by the Access Control (Port mode) are present.
(ii) Logical disks managed by the Access Control (WWN mode) are present.
(iii) Logical disks that are set in pairs are present.
Execute the batch binding after unset the states above.
(3) Disk relationship
When binding logical disks, it is necessary to understand the relationship between the physical disk, the RANK,
and the logical disk.
Figure 8-22 shows the relationship between the physical disk, the RANK, and the logical disk.

(4) Complement
In the batch binding, it is executed from RANK Bind to LD Bind all at once. In this case, both the RANK and
the LD are bound with the same capacity. Regarding the RANK binding, four patterns based on the
combinations of the PD count and the RAID type can be specified. However, when binding through other
settings, refer to 8.2 “Method of Binding Logical Disks”.
The screen displayed when binding logical disks in a batch and the details are described below.
Physical Disks (PDs)
RANK
Logical Disks (LDs)
The unit of physical disks comprising a
RAID is called RANK. The capacity of a
RANK is not a simple total of physical disk
capacities but varies with the RAID type.
Logical disks are bound in the RANK.
Multiple logical disks can be created in a
single RANK.
