Before importing the HA replication pairs, make sure of the
following:
- Both primary and secondary storage systems of the high availability (HA) pairs are onboarded on Ops Center Administrator.
- The data flow for HA pairs is created with the following conditions in
Ops Center Protector:
- The node for the primary storage is Hitachi Block Host.
- The logical devices for the primary volumes are defined in the
Included Logical Devices of the Hitachi Block Host.
The logical device must be defined with the LDEV_ID. Ops Center Administrator cannot use logical devices defined with Host Group ID.
- Specify Use Block Host selections in the Specify Hitachi Block Storage classification attributes of the policy.
- Configure the following in Secondary Volume Host Groups in
the Dataflow:
- Specify Automatically Provisioned Host Group.
- Do not specify any host groups in Optionally specify on or more host groups on the destination storage system.
- Replication is marked as Active Full Copy in Ops Center Protector.
- The HA pair must use a Quorum disk.
Note:
- If you add or remove pairs in the replication group, the logical device range will be regenerated and the updated logical device specification will be listed as a list of single logical device specification and the Excluded Logical Devices specification will be retained.
- Do not specify optional host groups in Secondary Volume Host Groups on Ops Center Protector after you import the replication. If you specify optional host groups, unexpected paths between the hosts and volumes may be created when adding or removing pairs in the replication group.
-
Select the primary storage systems of the HA pair on which you want to import HA
replication.
