The I/O between the replicated pairs is suspended, but the replication is maintained.

The I/O between the replicated pairs resumes and out-of-sync data is resynchronized. NOTE: This option is available only for replicated pairs that have been suspended. Changing Remote Replication Roles Changing roles makes the following role changes in the replicated pair: • Promotes the secondary virtual disk to the primary virtual disk and allows read/write access from the remote location. • Demotes the primary virtual disk to the secondary virtual disk and disables writes to the virtual disk from the primary site. To change roles, click Change Replication Roles. Testing Remote Replication Testing remote replication displays the round trip times between the virtual disks in the replicated pair. The times are displayed as average round trip times, shortest round trip times, and longest round trip times. To test remote replication, click Test Replication Communication.

Remote Replication Confirmation
Suspending Remote Replication
To suspend remote replication of a disk pair, click
Suspend Replicating
in the
Commands
area under the
Remote Replication
tab. The I/O between the replicated pairs is suspended, but the replication is maintained.
Resuming Remote Replication
To resume remote replication, click
Resume Replicating
in the
Commands
area under the
Remote
Replication
tab. The I/O between the replicated pairs resumes and out-of-sync data is resynchronized.
NOTE:
This option is available only for replicated pairs that have been suspended.
Changing Remote Replication Roles
Changing roles makes the following role changes in the replicated pair:
•
Promotes the secondary virtual disk to the primary virtual disk and allows read/write access from the
remote location.
•
Demotes the primary virtual disk to the secondary virtual disk and disables writes to the virtual disk
from the primary site.
To change roles, click
Change Replication Roles
.
Testing Remote Replication
Testing remote replication displays the round trip times between the virtual disks in the replicated pair. The
times are displayed as average round trip times, shortest round trip times, and longest round trip times.
To test remote replication, click
Test Replication Communication
