HP XP P9500 Storage - Manual (Page 124)

D Configuration operations (secondary window)
This appendix provides instructions for configuring BC Z using the previous RWC GUI, which opens
in a secondary window.
Configuration workflow
Setup for BC Z consists of the following:
1. Ensuring that source and target volumes are set up correctly.
2. (Optional) Reserving volumes for use as T-VOLs.
3. Setting the HOST I/O Performance option, which boosts I/O performance, though copy time
slows as a result. (Optional.)
Setting up source and target volumes
Set up the source and target volumes before making copies. Ensure that the volumes you plan to
use meet the requirements for pair volumes in
“Planning pair volumes” (page 15) .
Reserving T-VOLs
This is an optional feature you can use to reserve volumes that are not assigned to a pair (SIMPLEX
status) for use as T-VOLs. The storage system rejects write I/Os to reserved volumes except those
that are split (Split/SUSPOP status).

•
Not assigned to a pair (“SIMPLEX” status)

3. Change to Modify mode by clicking the icon.
4. In the tree in the Pair Operations window, select the appropriate port or host group CU image
for the volumes you want to reserve.
