Resource Registration
If the backup server resides in a cluster domain (called a backup domain) that is different from the primary domain, those disks which are registered as resources in the primary domain or are to be registered with classes restored in the backup domain may not be involved in the resource registration in the backup domain. For details on the resource registration, refer to "6.3 Shared Disk Resource Registration."
1) Creating an application volume
Create an application mirror volume onto application disks sda and sdb. The following settings are necessary on Node1 and Node2 in the primary domain.
1-1) Registering disks
Register disks sda and sdb with shared class Class1 that is shared on Node1and 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 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 into mirror group Group1.
# sdxvolume -M -c Class1 -g Group1 -v Volume1 -s 1048576 |
2) Synchronizing backup disks
Synchronize application disks sda and sdb, as copy sources, respectively with disks sdc and sdd, as copy destinations, with copy functions of the disk units.
See
For the synchronization methods, see the manuals of disk units for information regarding copy functions.
Note
Backup disks must be equivalent in size application disks to be backed up.
