Creating asynchronous replication
To create asynchronous replication do the following:
1.
Right-click on the primary storage array and click Configure replication.
2. From the Replication mode drop-down, select Snap-assisted. SMC Manager will
list available storage arrays suitable for asynchronous replication.
3. To use the default backup schedule, select the storage array that is to be
secondary and click Synchronize.
4. To configure a custom backup schedule, click Advanced, edit the fields as
desired, and click Synchronize
5. After the configuration is complete, the secondary storage array will be listed
under the primary storage array.
Note: Even though the link between the two arrays is complete, the
asynchronous replication operation can continue for some time depending on
the number of user volumes that are already created on the primary storage
array.
Manual failover
In the event of a problem with the primary storage array, you can promote the
secondary array to become the primary array.
To promote the secondary array, do the following:
1.
Right-click on the secondary storage array and click Promote to Primary
2. After the process completes, the secondary storage array is now the primary.
The original primary array is no longer provisioned and is removed from the
storage array tree.
3. Reset the DHCP root path to point to the new primary storage array.
4. The original storage array can now be re-provisioned and configured as a
secondary storage array using the steps shown in “Creating synchronous
replication” on page 51.
Note: Before you promote the secondary array, you should check the status of
the replication. Right-click on the secondary array entry under the primary
array in the SMC Manager and select Replication status. The replication
progress window will be displayed showing the overall replication progress as
well as the progress of each image. If the secondary array is promoted before
replication is complete, some images may not be available on the secondary
array once it is promoted.
