VSAN Issues
Resolving an Isolated E Port Using Fabric Manager
To resolve VSAN isolation on an E port using Fabric Manager, follow these steps:
Step 1 Choose Switches > Interfaces > FC Physical and check the FailureCause column on the E port to verify
that you have a VSAN mismatch.
Step 2 Choose Switches > Interfaces > FC Physical and use the PortVSAN field to correct a VSAN mismatch.
Resolving an Isolated E Port Using the CLI
To resolve VSAN isolation on an E port using the CLI, follow these steps:
Step 1 Use the show interface command to verify that the port is isolated because of a VSAN mismatch.
switch# show interface fc2/4
fc2/4 is down fc2/4 is down (isolation due to port vsan mismatch)
Hardware is Fibre Channel, WWN is 20:44:00:05:30:00:63:5e
vsan is 4
Beacon is turned off
30 frames input, 682 bytes, 0 discards
0 runts, 0 jabber, 0 too long, 0 too short
0 input errors, 0 CRC, 0 invalid transmission words
0 address id, 0 delimiter
0 EOF abort, 0 fragmented, 0 unknown class
30 frames output, 583 bytes, 0 discards
Received 2 OLS, 2 LRR, 2 NOS, 5 loop inits
Transmitted 5 OLS, 3 LRR, 2 NOS, 4 loop inits
Step 2 Use the show vsan membership command to verify that the ports are in separate VSANs.
switch# show vsan membership
vsan 3 interfaces:
fc2/1 fc2/2 fc2/3 fc2/4 fc2/6 fc2/7 fc2/8 fc2/9
fc2/10 fc2/11 fc2/12 fc2/14 fc2/15 fc2/16 fc7/1 fc7/2
fc7/3 fc7/4 fc7/5 fc7/6 fc7/7 fc7/8 fc7/9 fc7/10
fc7/11 fc7/12 fc7/13 fc7/14 fc7/15 fc7/16 fc7/17 fc7/18
fc7/19 fc7/20 fc7/21 fc7/22 fc7/23 fc7/24 fc7/25 fc7/26
fc7/27 fc7/28 fc7/29 fc7/30 fc7/31 fc7/32
vsan 4 interfaces:
fc2/5 fc2/13
vsan 4094(isolated_vsan) interfaces:
This sample output shows that all the interfaces on the switch belong to VSAN 3, with the exception of
interface fc2/5 and fc2/13, which are part of VSAN 4.
Step 3 Use the vsan database vsan vsan-id interface command to move the ports into the same VSAN.
