Running The Test Procedure On A Non-Preconfigured Environment; Running A Reprotect Procedure - IBM DS8000 User Manual

The preconfigured FlashCopy target volumes are resynchronized during the test
procedure.
Ensure that all of the steps that are outlined in "Setting up preconfigured
environments for DS8000 Remote Copy for SRA" on page 18 are completed.
Running the Test procedure on a non-preconfigured
environment
The IBM DS8000 SRA completely automates the Test procedure.
During this procedure, the SRA creates SE FlashCopy target volumes if the SE
volume support feature is enabled and SE storage is defined on the storage array is
specified. If the recovery site DS8000 does not have SE support that is enabled, the
SRA creates fully-allocated volumes for test failover operations. The only
prerequisite that this procedure needs, from the SRA's perspective, is enough free
capacity available in one of the extent pools to accommodate the FlashCopy target
volumes.
During the cleanup procedure, the FlashCopy relationships and FlashCopy target
volumes that are created during the test procedure are deleted.
Prerequisites for the SRA Test procedure
v Have enough free space available on the Extent Pool.
v Complete all the steps that are outlined in "Setting up non-preconfigured
environments for DS8000 Remote Copy for SRA" on page 20.

Running a Reprotect procedure

The IBM DS8000 SRA completely automates the Reprotect procedure.
Before you run the Reprotect action, refresh the Devices window of the SRM Array
Managers to ensure that no error messages occur.
During the Reprotect procedure, the Metro/Global Mirror/Metro-Global Mirror
direction changes from the original recovery (secondary) site to the original
protected (primary) site, and the mirroring action is resumed.
Note:
v Original protected volumes are detached from the host during the Reprotect
procedure for non-preconfigured scenarios.
v For Metro-Global Mirror, the initial direction is Site A (protected site) > Site B
(intermediate site) > Site C (recovery site). After the first reprotect procedure to
initial direction, the direction is changed to Global Mirror: Site C (protected site)
> Site A (recovery site). After the second Reprotect procedure, the direction will
be changed back to Metro-Global Mirror: Site A > Site B > Site C.
Prerequisites for the SRA reprotect procedure
v For non-preconfigured Global Mirror/Metro-Global Mirror, ensure that there is
enough free space available on the Extent Pool of the original remote copy
source volume.
v For preconfigured environments, complete all the steps that are outlined in
"Setting up preconfigured environments for DS8000 Remote Copy for SRA" on
page 18.
