5 Managing Business Copy Z pairs

Abstract
This chapter provides instructions for completing BC Z pair user tasks using the RWC and information
on ATTIME Suspend using BCM.

Workflow for managing Business Copy Z pairs

During most pair user tasks, the P-VOL remains available to the host for I/O operations. You must
have the Storage Administrator (Local Copy) role to perform BC Z pair user tasks.
Use the following workflow to complete pair user tasks:
1. Check the pair status (see
For more information about the required status for pair user tasks, see
pair user tasks" (page
2. Create the BC Z pairs (see
3. (Optional) Suspend the BC Z pair creation.
For more information about suspending BC Z pair creating, see
creation" (page
4. (Optional) Suppress update copy operations during pair restoration (see
copy operations during pair restoration" (page
5. Split the pairs. You can do the following:
Split BC Z pairs (see
Split BC Z pairs in a CG (see
6. Resynchronize or restore the BC Z pairs (see
57)).
7. (Optional) If you have performed a Quick Resync on the pair ("DUPLEX" status), suppress copy
processing (see
8. Delete the BC Z pairs, which ends the pair relationship between the pair volumes (see
BC Z pairs" (page
In Business Copy Z, it might take a lot of time before a copy operation starts. This is because before
a copy operation starts, differential tables are initialized for the relevant pairs, one pair after
another, within the system. Especially when the pairs use a large volume of data, initialization can
be a very long process.
