Access Logix is an optional feature of the
firmware code that provides
the functionality 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 if 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 Lenovo Storage V series 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.
