212 Configuration: Premium Feature— Remote Replication
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:
• "Normally Synchronized Virtual Disks" on page 204.
• "Unsynchronized Virtual Disks" on page 207.
• "Setting Synchronization Priority and Synchronization Method" on
page 196.
• "Changing Synchronization Priority and Method" on page 205.
• "Resynchronizing Virtual Disks" on page 204.
• "Automatically Resynchronizing Virtual Disks" on page 208.
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
Logical
tab.
2
In the
Logical
pane, right-click the virtual disk.
3
Select
Test Replication Communication
.
The Replication Communication Test Progress message is displayed.
