Step 1
Map all the primary and secondary LUNs in the consistency group to the host.
1.
Log in to DeviceManager. Choose
Provisioning
>
LUN
>
LUN Group
. Click
Create
to create LUN groups and add the primary and secondary LUNs of the remote
replication task to corresponding LUN groups.
2.
Choose
Provisioning
>
Mapping View
. Choose the mapping view that the host
group which holds the application servers belongs to. Then add the newly created LUN
group to this mapping view.
NOTE
To check on a standby server whether data replication succeeds, you need to mount the secondary LUN to the
standby server. Before mounting the secondary LUN, split the LUN and set
Status of Secondary Resource
Protection
to
Read/Write
.
Step 2
Check whether data replication succeeded.
1.
Log in to the application server at the primary site and write file X1.txt to all primary
LUNs of the consistency group. When
Running Status
of the consistency group is
Normal
, go to the next step.
2.
Log in to DeviceManager at the primary site. Choose
Data Protection
>
Remote
Replication
>
Remote Replication Consistency Group
. Click the remote replication to
be synchronized. Choose
More
>
Synchronize
to perform the synchronization manually.
3.
Log in to the standby server at the secondary site to check whether data file X1.txt exists
on the secondary LUNs of the consistency group.
–
If yes, data replication succeeded.
–
If no, log in to DeviceManager at the primary site. Choose
Data Protection
>
Remote Replication
>
Remote Replication Consistency Group
. Click the
consistency group to be synchronized. Choose
More
>
Synchronize
to perform the
synchronization manually.
Step 3
Check whether a primary/secondary switchover can be performed on the secondary site.
1.
Log in to DeviceManager at the secondary site, choose
Data Protection
>
Remote
Replication
>
Remote Replication Consistency Group
, and perform the following
operations.
a.
Right-click the consistency group to be split and choose
More
>
Split
.
b.
Right-click the consistency group for which you want to disable secondary resource
protection. Choose
More
>
Disable Protection for Secondary Resource
to set
secondary LUNs of all remote replication pairs in the consistency group to readable
and writable.
c.
Right-click the consistency group for which you want to perform a primary/
secondary switchover. Choose
More
>
Primary/Secondary Switchover
to switch
secondary LUNs of all remote replication pairs in the consistency group to primary
LUNs.
2.
Log in to the standby server at the secondary site and write file Y1.txt to the new primary
LUNs. Check whether the primary LUNs are readable and writable.
–
If yes, a primary/secondary switchover can be performed on the secondary site.
–
If no, a primary/secondary switchover cannot be performed on the secondary site.
Check whether an alarm about remote replication exists on DeviceManager at the
primary and secondary sites. If yes, solve the fault based on the alarm information
and repeat the previous operations. If no, contact technical support engineers.
