3. Click Next.
The Select Synchronization Settings (Create Remote Replication (Legacy) wizard is displayed. Go to Setting
Synchronization Priority And Synchronization Method.
Setting Synchronization Priority And Synchronization Method
You can set the priority for allocating system resources to synchronizing the remote replication.
• Higher synchronization priorities allocate more resources to the process and might degrade I/O performance.
• Lower synchronization priorities allocate fewer resources to the process and have less impact on normal I/O
performance.
The initial synchronization priority and synchronization method you select can be changed later. For more information
about resynchronizing virtual disks in a remote replication, go to
Resynchronizing Virtual Disks .
To set Synchronization Priority and Synchronization Method:
1. In the Select Synchronization Settings (Create Remote Replication (Legacy) 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(Legacy) wizard is displayed. Go to
Completing The Remote Replication .
Completing The Remote Replication (Legacy)
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 (Legacy) 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 Viewing Information About
A Remote Replication Or Replication Repository Virtual Disk . Each virtual disk is also represented by a status icon in
the Devices tab on the EMW. For a description of each icon, see Virtual Disk Status Icons .
