3.
Select one or more replicated pairs. To select all replicated pairs, click Select All.
4.
Click Resume.
The Resume Replication Pair - Confirmation dialog is displayed.
5.
In the Confirmation text box, type Yes.
The remote virtual disk replication resumes.
NOTE: The Properties panes in the AMW for the local storage array and the remote storage array show the
Replication status as Synchronized for both the primary and secondary virtual disks.
About Resumed Remote Replications
When a remote virtual disk replication is suspended, data continues to write to the primary virtual disk, but is not
replicated to the secondary virtual disk. Writes to the primary virtual disk are persistently logged to the replication
repository virtual disks.
After communications are restored, data transfer between the primary virtual disk and the secondary virtual disk must
be resynchronized.
Depending on which resynchronization method you specify, the following occurs:
•
Automatic resynchronization — Data transfer automatically starts immediately after the virtual disks are
resynchronized.
•
Manual resynchronization — You must manually resume the remote virtual disk replication to restart the data
transfer. A suspended remote virtual disk replication stays in a Suspended status until it is manually resumed.
After the remote virtual disk replication resumes, data is automatically written to the secondary virtual disk. Only the
regions of the primary virtual disk that changed since the replicated pair was suspended are written to the secondary
virtual disk.
CAUTION: Possible loss of data access: When you resume a remote virtual disk replication involving a primary or
secondary virtual disk that is a member of a write consistency group, any other suspended remote replications for
replicated pairs in the write consistency group also resumes.
NOTE: If the write mode is synchronous, you do not need to resynchronize the primary and secondary virtual disk
after resuming a remote virtual disk replication.
Testing Communication Between The Primary And Secondary Virtual Disks
When a resynchronization is manual or during a disaster recovery scenario, you may want to test the communication
between the primary virtual disk and secondary virtual disk in a remote replication. For more information about
synchronization and resynchronization in remote virtual disk replications, go to these topics:

To test the communication between virtual disks in a remote replication:
1.
In the AMW of either the primary or secondary virtual disk, select the Storage & Copy Services tab.
2.
In the Logical pane, right-click the virtual disk.
