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 the LSAN zone status of a device, the port WWN, and the 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.
Do you want to enable 'zone_cfg' configuration (yes, y, no, n): [no] y
zone config "zone_cfg" is in effect

6. Log in as admin to fabric2.
7. Enter the nsShow command to list Target A (50:05:07:61:00:5b:62:ed) and Target B (50:05:07:61:00:49:20:b4).
