Abstract
A unique identifier is stored in shared data storage that is accessible to at least a first virtual storage processor and a second virtual storage processor within a virtual storage appliance. The unique identifier is generated when the virtual storage appliance is first started up, and then used by the first virtual storage processor to obtain at least one Internet Protocol (IP) address for use by a management stack that initially executes in the first virtual storage processor. In response to failure of the first virtual storage processor, the unique identifier is used by the second virtual storage processor to obtain, for use by the management stack while the management stack executes in the second virtual storage processor after the failure, the same IP address obtained by the first virtual storage processor.
