Hi raid-zero,  Welcome to EMC Community  If the local SYMAPI DB does not list the other array as remote (if SRDF is not implmented between the 2 arrays) then only the local array will be visible in Unisphere, You cannot have UNIVMAX manages 2 seperates arrays via 2 seperate SYMAPI DBs. Only one SYMAPI DB is used either local or remote.  So the answer to your question, You need 2 seperate instances of unisphere.  Hope this helps Mohammed Salem
Is it possible to point Unisphere for VMAX at two different SYMAPI instances, one local and one remote?  We have a situation where there is a VMAX at two different data centers, but we would like to manage them with a single Unisphere instance.  So the idea would be a SYMAPI server at both locations, but only one Unisphere install.  Currently we can view local or remote, but not both at the same time via Unisphere.  
Unisphere for VMAX - local AND remote
