9) Stopping services
Stop applications using application volume Volume1 on nodes Node1 and Node2 in the primary domain.
When using Volume1 as a file system, unmount the file system.
10) Stopping the application volume
On Node1 and Node2 in the primary domain, stop application volume Volume1. Execute the following command on Node1 or Node2
|
# sdxvolume -F -c Class1 -v Volume1 -e allnodes |
11) Deleting the class
In the primary domain, delete class Class1 to which application volume Volume1 belongs. Execute the following command on Node1 or Node2 in the primary domain.
|
# sdxvolume -R -c Class1 -v Volume1 |
12) Restoring data back from the backup disks
Restore data from backup disks c3t1d1 and c4t1d1, copy sources, as respectively back to application disks c1t1d1 and c2t1d1, as copy destinations, with disk unit's copy functions.
For the restore methods, see the manuals of disk units for information regarding copy functions.
13) Parting the backup disks (suspending synchronization)
After the restore process is completed, part backup disks c3t1d1 and c4t1d1 from application disks c1t1d1 and c2t1d1.
For the methods for suspending synchronization, see the manuals of disk units for information regarding copy functions.
14) Restoring the object configuration of the class
On Node1 or Node2 in the primary domain, according to the configuration table in the configuration file "/var/tmp/Class1.conf" created in step 3) of "Backing Up," restore the object configuration of Class1.
After restoring the object configuration, reboot the restored node.
|
# sdxconfig Restore -c Class1 -i /var/tmp/Class1.conf |
15) Changing the class type and expanding the class scope
If the backed up class, Class1, is a shared class, change the type and scope attributes of Class1. For the scope of backed up class Class1, check the SCOPE field of the class information output by the sdxinfo command and saved in step 3) of "Backing Up." In this example, the scope of backed up class Class1 is Node1:Node2.
15-1) Stop the volume in the class.
|
# sdxvolume -F -c Class1 |
15-2) Change the class type and expand the class scope.
|
# sdxattr -C -c Class1 -a type=shared,scope=Node1:Node2 |
16) Starting the application volume
On Node1 or Node2 in the primary domain, start application volume Volume1. Execute the following command on Nore1 or Node2.
16-1) Starting the application volume
Start application volume Volume1.
|
# sdxvolume -N -c Class1 -v Volume1 |
16-2) Reconfiguring the partition information of the GFS Local File System
When using application volume Volume1 as the GFS Local File System, reconfigure the partition information.
|
# sfxadm /dev/sfdsk/Class1/rdsk/Volume1 |
17) Resuming the services
When the file system on application volume Volume1 was unmounted in step 8) of "Backing up," unmount it again.
Start the applications using Volume1.
