Nonstop Database, HiRDB Version 9 Disaster Recovery System Configuration and Operation Guide
When Real Time SAN Replication is used, because the HiRDB systems at the main and remote sites are independent from each other, you cannot simply switch between the systems at the main site and a remote site. Furthermore, using a system switchover facility and Real Time SAN Replication together increases the time it takes to switch systems.
The following subsections describe the paired logical volume groups you need to specify in RAID Manager's configuration definitions when a system switchover facility is used. The following explanations assume that you are using the hybrid method for all paired logical volume groups.
