Resource Registration
If the backup server resides in a cluster domain (called a backup domain), those disks that are registered as resources in the primary domain or are to be registered with a shadow class in the backup domain may not be involved in the resource registration in the backup domain. For details on the resource registration, see "Shared Disk Unit Resource Registration."

 

1) Creating a master volume

In the primary domain, create the master volume that is used for the services operation.

The following example creates mirror group Group1 that consists of disks sda and sdb to shared class Class1 that is shared on nodes Node1 and Node2 and creates mirror volume Volume1.

# sdxdisk -M -c Class1 -a type=shared,scope=Node1:Node2 -d sda=Disk1,sdb=Disk2
# sdxdisk -C -c Class1 -g Group1 -d Disk1,Disk2
# sdxvolume -M -c Class1 -g Group1 -v Volume1 -s 1048576

 

2) Creating and joining a proxy group

Create a proxy volume as the copy destination of the master volume and join it to the master volume in the primary domain. The following settings are necessary on Node1 or Node2 in the primary domain.

2-1) Creating a proxy volume

Create a proxy volume in the same size as master volume Volume1 to shared class Class1 to which Volume1 belongs.

The following example creates mirror group Group2 that consists of only disk sdc and creates mirror volume Volume2.

# sdxdisk -M -c Class1 -d sdc=Disk3
# sdxdisk -C -c Class1 -g Group2 -d Disk3
# sdxvolume -M -c Class1 -g Group2 -v Volume2 -s 1048576

2-2) Stopping the proxy volume

Stop proxy volume Volume2 on all nodes.

# sdxvolume -F -c Class1 -v Volume2 -e allnodes

2-3) Joining the proxy volume

Relate and join proxy volume Volume2 to master volume Volume1.

# sdxproxy Join -c Class1 -m Volume1 -p Volume2

After returning from the command, synchronization copying from Volume1 to Volume2 is executed, and as a result, they become synchronized.
