Abstract
A technique handles a VDM failover situation. The technique involves adjusting a configuration file on a first platform to indicate whether data managed by an initial VDM on that platform is being replicated to a second platform. The technique further involves, following a VDM failover event, creating a replacement VDM on the first platform to replace the initial VDM. The technique further involves, after the replacement VDM is created, performing an operation that controls interfaces provided by the replacement VDM. The operation enables the interfaces when the operation determines that the data managed by the initial VDM on the first platform was not being replicated to the second platform at the time of the event, and disables the interfaces when the operation determines that the data managed by the initial VDM on the first platform was being replicated to the second platform at that time of the event.
