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 stripe volume used for the services on disks sda, sdb, sdc, and sdd. The following settings are necessary on Node1 or Node2 in the primary domain.

1-1) Registering disks

Register disks sda, sdb, sdc, and sdd with shared class Class1 that is shared on Node1 and Node2, and name them Disk1, Disk2, Disk3, and Disk4 respectively.

# sdxdisk -M -c Class1 -a type=shared,scope=Node1:Node2 -d sda=Disk1,sdb=Disk2,sdc=Disk2,sdd=Disk4

1-2) Creating a stripe group

Connect disks Disk1, Disk2, Disk3, and Disk4 to stripe group Group1.

# sdxdisk -C -c Class1 -g Group1 -d Disk1,Disk2,Disk3,Disk4 -a type=stripe,width=256

1-3) Creating a stripe volume

Create stripe volume Volume1 to stripe group Group1.

# sdxvolume -M -c Class1 -g Group1 -v Volume1 -s 1048576 -a pslice=off
