software is installed, including HP Command View EVA and HP Replication

Management Appliance. When there are multiple management servers in a
SAN, two active instances of HP Command View EVA are allowed, but each
array will only b e managed by one instance. The active management server
actively manages the array, while the standby management server takes control
of the
array if there is a failure on the active management server. There is only
one
active management server at a time for any given manag em ent zone in
aSAN.
