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.
