Dell PowerVault MD3820f - Manual (Page 210)

Only RAID controller modules configured for Remote Replication can communicate with the reserved
ports.
The Remote Replication premium feature must be activated on both the local and storage arrays.
NOTE: Perform the activation steps below on the local storage array first and then repeat them on
the remote storage array.
1. In the AMW of the local storage array, select the Storage & Copy Services tab.
2. Select Copy Services → Remote Replication → Activate.
3. If both Remote Replication and Remote Replication (Legacy) premium features are supported on
your storage array, select Remote Replication.
4. If you had selected standard Remote Replication, click Finish.
The Premium feature activation is complete.
5. If you had selected Remote Replication (Legacy), in the Create Repositories window, select where
the replication repository virtual disks for the Remote Replication (Legacy) feature must reside. Select
one of the following:
– Free capacity on existing disk pool or disk group — If this option is selected, a corresponding disk
pool or disk group must be selected.
– Unconfigured capacity on a new disk pool or disk group — If this option is selected, choose either
Disk Pool or Disk Group.
– Click Next.
The Create Disk Pool wizard or the Create Disk Group wizard is displayed.
6. Click OK.
The Remote Replication Activated window is displayed. The system performs when the Remote
Replication premium feature is activated:
– Logs out all hosts currently using the highest numbered Fibre Channel host port on the RAID
controller modules.
– Reserves the highest numbered Fibre Channel host port on the RAID controller modules for
replication data transmissions.
– Rejects all host communication to this RAID controller module host port as long as the
replication feature is active.
– If the Remote Replication (Legacy) feature has been activated, the two replication repositories are
created.
NOTE: Repeat these steps to activate the remote replication premium features on the remote
storage array.
Deactivating Remote Replication
Deactivating the Remote Replication premium feature removes RAID controller module port restrictions.
NOTE: Before deactivating the Remote Replication premium feature, delete all existing Remote
Replication groups and replicated virtual disk pairs from the local and remote storage arrays.
To deactivate the Remote Replication feature:
1. From the AMW, select Copy Services → Remote Replication → Deactivate.
A message prompts you to confirm if the Remote Replication premium feature is to be deactivated.
2. Click Yes.
