Failing Over a Failover Package
Note: Applies to high-availability NAS solutions only.
The specified package fails over to another server in the cluster. The failover
consists of stopping the package on the primary server (node), then starting the
package on the secondary server. This action does not affect the designated
ownership of the package. In other words, the primary node specified in the
package configuration doesn’t change. If the cluster were stopped and restarted,
the package would automatically migrate back to its primary node. This action
provides a mechanism for manually failing over packages without requiring a
failure condition. One use of this functionality is to allow manual load-balancing
without requiring the cluster or individual nodes to be reconfigured and/or
rebooted.
A package failover involves both stopping the existing package on one node and
starting the new instance of the package on the other node.
You would manually fail over a package when:
■
You need to take the primary server down for moving, cleaning, or service.
■
You want to transfer a package to the secondary server.
To fail over a package:
1. In Command View NAS, click the Storage tab.
2. Under Failover Packages, select the package you want to fail over by
clicking the row.
3. Select Actions > Manually Fail over/Back Selected Package.
