Figure 29 LDEV grouping up to and including XP24000/XP20000 Disk Array
For P9500 RAID storage systems, RAID Manager can be used to create a group of multiple LDEVs
by defining device groups. This is accomplished by defining device groups in either the primary
or secondary configuration definition file, but not both. By defining a device group, LDEV information
can be changed or defined in one operation. It is not required to modify LDEV information in both
configuration definition files. For example, referencing LDEVs or creating pools can be executed
at the same time because the whole LDEV in the device group is subjected to the operation.
