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

Name

Global

CanBeOnline

Reason

PuneWeb:FinanceApacheWeb

No

Yes

Already online

PuneWSphere:FinanceWebSphere

No

Yes

PuneDB:FinanceDB

Online on remote cluster MtViewVBS. At least one service group in virtual business service is not global

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.

Table: DR plan examples

Scenario

DR plan output

Global service group is faulted.

The plan shows that the global service group at the production site is FAULTED. The -force option will be used to bring the global service group online at the DR site.

Global service group is offline.

The plan shows that the global service group is offline at the production site. You can start the virtual business service at the DR site.

Production cluster is faulted.

The plan shows that the service group is global and that the production cluster is FAULTED or DOWN. When you start the virtual business service on the DR site, the -force option will be used to bring the global service group online at the DR site.

Global service group is online at the production site and there are one or more non-global service groups in the virtual business service.

The plan shows that the production cluster is up and the global service group is online on the production cluster. You cannot start the virtual business service at the DR site.

Global service group is online at the production site and all service groups are global.

The plan shows the status of each service group on the production site. The -switch option will be used to bring the global service groups online at the DR site for the global service groups that are online at the production site.
