An LSAN is a Logical Storage Area Network that spans multiple Physical fabrics and allows specified devices from these autonomous fabrics to communicate with each other without merging the physical fabrics. In other word, A logical network that spans multiple physical fabrics. It allows specified devices from the autonomous fabric to communicate with each other using a FC router without merging the physical fabrics.
- A LSAN zone is a traditional zone with a special naming convention.
- Zone names must start with “LSAN_” or “lsan_” or “LSan_”
- LSAN zones are architecturally comaptiable with FOS and M-EOS
- FC Router uses LSAN zones to determine which devices need to be exported/imported into which routed fabrics.
- LSAN zones must be configured in all fabrics where the shared physical devices exist.
- The router performs zoning enforcement for edge fabrics at the ingress Router EX Port.
LSAN Implementation Rules:
- LSAN zone members must be defined using the device Port WWN, Zone members, including aliases, need to be defined using WWPN.
- LSAN zone name on the routed fabrics do not need to be identical, but is recommended for
ease of administration and troubleshooting.
- LSAN zones in routed fabrics sharing devices are not required to have identical membership. Shared devices must exist in both fabrics LSAN zones.
Once the LSAN zones are enabled, you will be able to check status of LSAN zones and members from the FC Router using the command lsanzoneshow –s
Router:admin>lsanzoneshow –s
Fabric ID: 1 Zone Name: lsan_zone1
10:00:00:00:98:23:12:11 Exist
10:00:00:00:98:23:ab:cd Imported
Fabric ID: 2 Zone Name: lsan_zone1
10:00:00:00:98:23:12:11 Imported
10:00:00:00:98:23:ab:cd Exist
The output reveals what devices are “Exported (Exist) and Imported from all the routed fabrics.
