Completing The Remote Replication; Raid Controller Module Ownership/Preferred Path - Dell PowerVault MD3260i Administrator's Manual

To set Synchronization Priority and Synchronization Method:
1. In the Select Synchronization Settings (Create Remote Replication) wizard, select the synchronization priority on
the slide bar.
2. Select either Manual or Automatic resynchronization.
– Automatic resynchronization — Resynchronization starts immediately after communication is restored
between unsynchronized replicated virtual disks.
– Manual resynchronization (recommended) — The replicated pair must be manually resynchronized each
time communication is restored between unsynchronized replicated virtual disks.
3. Click Next.
The Preview (Create Remote Replication) wizard is displayed. Go to

Completing The Remote Replication

CAUTION: Creating a replicated virtual disk pair starts a process between the primary and secondary virtual disks
that overwrites ALL existing data on the secondary virtual disk and set the disk to read-only access. If you have
existing data on your secondary virtual disk: (1) stop all I/O to the disk, (2) back up the data and (3) unmount any file
systems mounted to the secondary virtual disk before creating the replicated virtual disk pair.
After selecting the synchronization settings, perform these steps to complete the remote replication:
1. In the Preview (Create Remote Replication) wizard, type Yes to confirm the synchronization and click Finish.
The following confirmation message is displayed:
Creation Successful (Create Remote Replication)
2. If you want to create another replication pair, click Yes and repeat the steps. Otherwise, click No to exit.
– In the AMWs of both the local storage array and the remote storage array, the Logical panes show the
replicated virtual disk pairs as members of their disk groups.
– In the local storage array, the Properties pane displays the Replication status as Synchronizing and the
Synchronization – Progress bar shows estimated time to completion.
To view detailed information about the virtual disks in a remote replication, go to either

RAID Controller Module Ownership/Preferred Path

During a remote replication operation, the RAID controller module that owns the primary virtual disk must correspond to
the RAID controller owning the secondary volume on the remote array. If both virtual disks do not have the same
preferred RAID controller module when a remote replication begins, the ownership of the secondary virtual disk is
automatically transferred to the preferred RAID controller module of the primary virtual disk.
• When the remote replication is completed or is stopped, ownership of the secondary virtual disk is restored to
its preferred RAID controller module.
• If ownership of the primary virtual disk is changed during the remote replication, ownership of the secondary
virtual disk is also changed.
If any of the following conditions apply to your RAID controller module, you must manually change module ownership to
the alternate RAID controller module to allow the remote replication to finish:
• The status of the remote replication is In Progress.
• The preferred RAID controller module of the primary virtual disk fails.
