Abstract
A technique performs virtual storage processor (VSP) failover. The technique involves accessing, by a first physical storage processor of the data storage apparatus, a VSP to create an operating environment for a host file system from the first physical storage processor. The technique further involves, after accessing the VSP to create the operating environment for the host file system from the first physical storage processor, detecting a failure of the first physical storage processor. The technique further involves accessing, in response to detecting the failure of the first physical storage processor and by a second physical storage processor of the data storage apparatus, the VSP to re-create the operating environment for the host file system from the second physical storage processor.
