Bind logical disks of the disk array in accordance with the following procedure in terms of each PD group.
(1)
Spare Bind
It is necessary to set Spares in accordance with their applications. For information on Spares, refer to 2.3 "Spare".
(2)
Pool/RANK Bind
After considering the RAID characteristics, bind the RAID type pools suitable to the application.
Refer to Appendix C "RAID" for the types of RAID.
In pool or RANK binding, pay attention to the fact that the maximum capacity of the logical disk is less than the
pool or RANK capacity.
(3)
LD Bind
Bind the logical disk with the most suitable capacity in accordance with its application. It is impossible to set a
pair unless the logical disk capacity is the same; therefore, when using data replications, it is necessary to bind
logical disks of the same capacity beforehand.
