About the disaster recovery plan
The disaster recovery plan (DR plan) provides the sequence of operations that will be performed at the DR site, in the event of a disaster. To view the Virtual Business Services DR plan, use the vbssvc -showplan command. You can run this command from the production site or from the DR site.
The command output might resemble the following:
# vbssvc -showplan FinanceVBS
VCS NOTICE V-16-25-40234 virtual business service FinanceVBS
cannot be started.
Note: |
This prediction is based on the last discovered state of the service groups. The actual start operation can still fail if the underlying high availability technology is not available or due to external factors like network outages. |
Table: DR plan examples lists a few scenarios and possible DR plan command outputs.
