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. 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.
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 non-disruptive.
Tip
If a VSAN is in interop mode, you cannot restart the fcdomain for that VSAN disruptively.
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 restart disruptive
option to apply most of the configurations to their corresponding runtime values.
To restart the fabric disruptively or nondisruptively, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fcdomain restart vsan 1
switch(config)# fcdomain restart disruptive
vsan 1
