Use the normal disruptive device configuration procedure in the following cases:
- Fibre: If a new Fibre Channel connection is being installed. New Fibre Channel connections can only be installed when the host system is powered off. New devices under existing Fibre Channel ports can be installed and configured non-disruptively.
- Maxvgs: If the maxvgs parameter needs to be changed. The procedure for changing the maxvgs value in the system kernel requires a system reboot.
