• VSAN reported to be down (Initializing state).
Zones are active.
•
Both host and storage are logged into the SAN.
•
In this failure, the storage port is not logged into the active zone set.
After examining the interface, the error can be seen as in the following example.
Example:
switch(config-if)# show interface fc 2/4 trunk vsan 10
fc2/4 is trunking
Vsan 10 is down (Isolation due to domain id assignment failure)
switch(config-if)# show port internal info interface fc 2/4 | grep Isolation
fc2/4, Vsan 10 - state(down), state reason(Isolation due to domain id assignment
failure), fcid(0x000000)
fc2/4, Vsan 50 - state(down), state reason(Isolation due to vsan not configured on
peer), fcid(0x000000)
Possible Cause
The VSANs might have the same static Domain ID configured.
Example:
switch(config-if)# show fcdomain domain-list vsan 10
Number of domains: 1
Domain ID
---------
0x53(83)
switch(config)# show fcdomain domain-list vsan 10
Number of domains: 1
Domain ID
---------
0x53(83)
Solution
Change the Domain ID on one of the VSANSs.
Example:
switch(config)# vsan database
switch(config-vsan-db)# vsan 10 suspend
switch(config-vsan-db)# no vsan 10 suspend
switch(config-vsan-db)# show interface fc 2/4
Number of domains: 1
Domain ID
---------
0x52(82)
switch(config-vsan-db)# sho interface fc 2/4
Trunk vsans (admin allowed and active) (1,10,50,100)
Trunk vsans (up)
Trunk vsans (isolated)
