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 an application volume

Create a mirror volume used for the services operation on disks (standard devices) emcpowera and emcpowerb. The following settings are necessary on Node1 or Node2 in the primary domain.

1-1) Registering disks

Register disks (standard devices) emcpowera and emcpowerb with shared class Class1 that is shared on Node1 and Node2, and name them Disk1 and Disk2 respectively.

# sdxdisk -M -c Class1 -a type=shared,scope=Node1:Node2 -d emcpowera=Disk1,emcpowerb=Disk2

1-2) Creating a mirror group

Connect disks Disk1 and Disk2 to mirror group Group1.

# sdxdisk -C -c Class1 -g Group1 -d Disk1,Disk2

1-3) Creating a mirror volume

Create mirror volume Volume1 to mirror group Group1.

# sdxvolume -M -c Class1 -g Group1 -v Volume1 -s 1048576

 

2) Synchronizing a BCV

Relate standard device emcpowera to BCV device emcpowerc that will be the copy destination. The following settings are necessary on both nodes Node1 and Node2 in the primary domain.

2-1) Creating a device group

Create device group DevGroup.

# symdg create DevGroup

2-2) Registering a standard device

Register standard device emcpowera with device group DevGroup, and name it STD001 as a logical device.

# symld -g DevGroup add pd /dev/emcpowera STD001

2-3) Relating a BCV device

Relate BCV device emcpowerc to device group DevGroup, and name it BCV001 as a logical device.

# symbcv -g DevGroup associate pd /dev/emcpowerc BCV001

2-4) Establishing a BCV pair (synchronized)

Synchronize standard device STD001 with BCV device BCV001.

# symmir -g DevGroup -full establish STD001 bcv ld BCV001
