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 on disks sda and sdb. The following settings are necessary on Node1 or Node2 in the primary domain.
1-1) Registering disks
Register disks sda and sdb 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 sda=Disk1,sdb=Disk2 |
1-2) Creating a mirror group
Connect 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 |
