Access Logix is an optional feature of the firmware code that provides the function that
is known as LUN Mapping or LUN Virtualization.
You can use the software tab in the storage systems properties page of the EMC Navisphere GUI to
determine whether Access Logix is installed.
After Access Logix is installed, it can be disabled but not removed. The following two modes of
operation are available for Access Logix:
- Access Logix not installed: All LUNs are accessible from all target ports by any host.
Therefore, the SAN fabric must be zoned to ensure that only the Storwize V5000 system can access the target
ports.
- Access Logix enabled: A storage group can be formed from a set of LUNs. Only the hosts that are
assigned to the storage group are allowed to access these LUNs.
