About Domain Restart
Fibre Channel domains can be started disruptively or nondisruptively. If you perform a disruptive restart,
reconfigure fabric (RCF) frames are sent to other switches in the fabric and data traffic is disrupted on
all the switches in the VSAN (including remotely segmented ISLs). If you perform a nondisruptive
restart, build fabric (BF) frames are sent to other switches in the fabric and data traffic is disrupted only
on the switch.
If you are attempting to resolve a domain ID conflict, you must manually assign domain IDs. A
disruptive restart is required to apply most configuration changes, including manually assigned domain
IDs. Nondisruptive domain restarts are acceptable only when changing a preferred domain ID into a
static one (and the actual domain ID remains the same).
A static domain is specifically configured by the user and may be different from the runtime domain. If
Note
the domain IDs are different, the runtime domain ID changes to take on the static domain ID after the
next restart, either disruptive or nondisruptive.
If a VSAN is in interop mode, you cannot disruptively restart the fcdomain for that VSAN.
Tip
You can apply most of the configurations to their corresponding runtime values. Each of the following
sections provide further details on how the fcdomain parameters are applied to the runtime values.
The fcdomain restart command applies your changes to the runtime settings. Use the disruptive option
to apply most of the configurations to their corresponding runtime values, including preferred domain
IDs (see the

To restart the fabric disruptively or nondisruptively, perform this task:
Command
Step 1
switch# configuration terminal
switch(config)#
Step 2
switch(config)# fcdomain restart vsan vsan-id
switch(config)# fcdomain restart disruptive
vsan vsan-id
