LSAN zones and fabric-to-fabric communications

Zoning is enforced by all involved fabrics; any communication from one fabric to another must be
allowed by the zoning setup on both fabrics. If the SANs are under separate administrative control,
then separate administrators maintain access control.

Controlling device communication with the LSAN

The following procedure illustrates how LSANs control which devices can communicate with each
other. The procedure shows the creation of two LSANs (called lsan_zone_fabric75 and
lsan_zone_fabric2), which involve the following devices and connections:
Switch1 and the host in fabric75.
Switch2, Target A, and Target B in fabric2.
Switch1 is connected to the FC router using an EX_Port or VEX_Port.
Switch2 is connected to the FC router using another EX_Port or VEX_Port.
Host has WWN 10:00:00:00:c9:2b:c9:0c (connected to switch1).
Target A has WWN 50:05:07:61:00:5b:62:ed (connected to switch2).
Target B has WWN 50:05:07:61:00:49:20:b4 (connected to switch2).
1. Log in as admin and connect to switch1.
2. Enter the nsShow command to list the WWN of the host (10:00:00:00:c9:2b:c9:0c).
NOTE
The nsShow output displays both the port WWN and node WWN; the port WWN must be used
for LSANs.

3. Enter the zoneCreate command to create the LSAN lsan_zone_fabric75, which includes the
host.
switch:admin> zonecreate "lsan_zone_fabric75", "10:00:00:00:c9:2b:c9:0c"
4. Enter the zoneAdd command to add Target A to the LSAN.
FID75Domain5:admin> zoneadd "lsan_zone_fabric75", "50:05:07:61:00:5b:62:ed"
5. Enter the cfgAdd or cfgCreate and cfgEnable commands to add and enable the LSAN
configuration.
switch:admin> cfgadd "zone_cfg", "lsan_zone_fabric75"
switch:admin> cfgenable "zone_cfg"
You are about to enable a new zoning configuration.
This action will replace the old zoning configuration with the
current configuration selected.
