Automatic 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. In the backup domain, those relevant disks must be described in the Excluded Device List prior to executing the automatic resource registration. For details on the automatic resource registration, see "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration."
1) Creating an application volume
Create a mirror volume used for the services operation on disks (standard devices) emcpower1 and emcpower2. The following settings are necessary on Node1 or Node2 in the primary domain.
1-1) Registering disks
Register disks (standard devices) emcpower1 and emcpower2 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 emcpower1=Disk1,emcpower2=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 emcpower1 to BCV device emcpower3 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 emcpower1 with device group DevGroup, and name it STD001 as a logical device.
|
# symld -g DevGroup add pd /dev/rdsk/emcpower1 STD001 |
2-3) Relating a BCV device
Relate BCV device emcpower3 to device group DevGroup, and name it BCV001 as a logical device.
|
# symbcv -g DevGroup associate pd /dev/rdsk/emcpower3 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 |
