volumes can be...

The following figure depicts the setup window configuration items in theglobal-active device environment:
• Select Storage Systems (see 
 below, this task must be done first)
Note:  When global-active device pairs are allocated, the primary storage
system contains the P-VOLs and the secondary storage system contains the S-VOLs.
The following setup tasks can be performed in any order, but must be
completed before allocating global-active device pairs.
• Configure Remote Paths (see 
)
• Configure Quorum...
