Promote an Inbound Replica Set to a Recovery Volume, Where to Go from Here

Page 270 highlights

4. Click Replicate to partner to open the Replicate Recovery Volume dialog box. 5. Specify the group administrator account name and password. 6. Select whether to perform the replication by using manual transfer replication. 7. Select whether to save the primary group administrator account name and password for future use in the current GUI session. 8. Click OK. Monitor the Replicate to Partner operation to make sure that all tasks complete: 1. Open the Alarms panel at the bottom of the GUI window. 2. Click the Failback Operations tab. If an individual task fails, you must correct the problem and then retry the task. When the volume demote task on the primary group completes, the original volume disappears from the list of volumes, and the failback replica set appears under Inbound Replicas in the far-left panel. Where to Go from Here • To create more replicas, select the recovery volume and click Create replica. You can also configure replication schedules on the recovery volume. • When you are ready, you can fail back to the primary group. Promote an Inbound Replica Set to a Recovery Volume To temporarily fail over a volume (or template or thin clone) to the secondary group, you promote the inbound replica set to a recovery volume (or recovery template or recovery thin clone) and snapshots. Users can connect to the recovery volume and resume accessing the volume data. A recovery volume name is generated automatically, based on the volume name, with a dot-number extension (for example, vol01.1). You can choose to keep the same iSCSI target name as the original volume to facilitate iSCSI initiator connections to the recovery volume. Promoting an inbound replica set does not require any additional space on the secondary group, because it reduces delegated space by the size of the volume's replica reserve. Recovery volumes are thin provisioned. With some exceptions, all volume operations apply to a recovery volume. The following prerequisites and considerations apply: • You cannot convert a recovery template to a standard volume. You must first make the promotion permanent. • Make sure snapshots are offline before you perform this task. • You cannot detach a recovery thin clone. • Some exceptions that apply to volume operations also apply to a recovery volume. • When prompted to keep the ability to demote a replica set, make sure that you keep this ability, unless you are permanently promoting the replica set. To promote an inbound replica set: 1. Click Replication. 2. Expand the replication partner. 3. Expand Inbound Replicas and then select the replica set. 4. Click Promote to volume. 5. Confirm that you want to pause inbound replication from the partner. Replication resumes automatically for all other volumes after the replica set is promoted. 6. In the Promote replica set - Volume options dialog box: • Set the volume online if you want initiators to connect to it. 270 About Data Recovery

4.
Click
Replicate to partner
to open the Replicate Recovery Volume dialog box.
5.
Specify the group administrator account name and password.
6.
Select whether to perform the replication by using manual transfer replication.
7.
Select whether to save the primary group administrator account name and password for future use in the current GUI session.
8.
Click
OK
.
Monitor the Replicate to Partner operation to make sure that all tasks complete:
1.
Open the Alarms panel at the bottom of the GUI window.
2.
Click the
Failback Operations
tab. If an individual task fails, you must correct the problem and then retry the task.
When the volume demote task on the primary group completes, the original volume disappears from the list of volumes, and the
failback replica set appears under Inbound Replicas in the far-left panel.
Where to Go from Here
To create more replicas, select the recovery volume and click
Create replica
. You can also
configure
replication schedules on the
recovery volume.
When you are ready, you can fail back to the primary group.
Promote an Inbound Replica Set to a Recovery Volume
To temporarily fail over a volume (or template or thin clone) to the secondary group, you promote the inbound replica set to a
recovery volume (or recovery template or recovery thin clone) and snapshots. Users can connect to the recovery volume and
resume accessing the volume data.
A recovery volume name is generated automatically, based on the volume name, with a dot-number extension (for example,
vol01.1
). You can choose to keep the same iSCSI target name as the original volume to facilitate iSCSI initiator connections to the
recovery volume.
Promoting an inbound replica set does not require any additional space on the secondary group, because it reduces delegated space
by the size of the volume’s replica reserve. Recovery volumes are thin provisioned.
With some exceptions, all volume operations apply to a recovery volume.
The following prerequisites and considerations apply:
You cannot convert a recovery template to a standard volume. You must
first
make the promotion permanent.
Make sure snapshots are
offline
before you perform this task.
You cannot detach a recovery thin clone.
Some exceptions that apply to volume operations also apply to a recovery volume.
When prompted to keep the ability to demote a replica set, make sure that you keep this ability, unless you are permanently
promoting the replica set.
To promote an inbound replica set:
1.
Click
Replication
.
2.
Expand the replication partner.
3.
Expand
Inbound Replicas
and then select the replica set.
4.
Click
Promote to volume
.
5.
Confirm
that you want to pause inbound replication from the partner. Replication resumes automatically for all other volumes
after the replica set is promoted.
6.
In the
Promote replica set – Volume options
dialog box:
Set the volume online if you want initiators to connect to it.
