This sub-section describes the procedure when switching the service from the operation system to a disaster recovery system in the event of disasters.
The outline of switching procedure is as follows:
Cancel copying of storage.
When using the copy function per LUN (such as ACM CCM) of storage, restore object configuration information on a disaster recovery system by using the configuration files of the disaster recovery system created in step 2 in "I.1 Building a Disaster Recovery System." (sdxconfig Restore command)
In the sdxconfig Restore command, -e chkps option is set.
After executing the sdxconfig Restore command, reboot the server where the sdxconfig Restore command was executed.
After the server is restarted, set the shared class (change type from local to shared) using (sdxattr -C command) and set using (hvgdsetup -a command) to use the shared class in the cluster application.
When mirroring storage on a disaster recovery system, add a disk to a mirror group on a disaster recovery system. (sdxdisk -M and sdxdisk -C commands)
