SCF Commands (G-series only)
SCF Commands (G-series only)
In G-series RVUs, PUP functions are performed by SCF.
SCF is an interactive interface for configuring, controlling, and collecting information
from a subsystem and its objects. SCF enables you to configure and reconfigure
devices, processes, and some system variables while your NonStop S-series server is
online.
SCF ALTER DISK, LABEL
The ALTER DISK, LABEL command erases the existing files and writes a volume label
on a new or previously labeled volume.
SCF RENAME
The RENAME command replaces only the default or alternate name of the volume
(VOLNAME or ALTNAME options). If you use the ALTER DISK, LABEL command to
change both names, all files on the volume are deleted.
SCF INITIALIZE DISK
The INITIALIZE DISK command erases existing files, labels the disk, and starts it.
SCF STOP DISK and SCF START DISK
The SCF STOP DISK command performs an implicit remove. (An implicit remove is
also performed when the system is shut down.)
The SCF START DISK command performs an implicit revive, if needed, to update one
half of a mirrored volume.
SCF STOP and SCF START
The SCF STOP command stops the object in an orderly way. The device is not
stopped until the current activity ends.
The SCF START command starts the object or process if it is in a STOPPED state,
making it available to user processes. START DISK is also used to revive one half of a
mirrored volume that is in a STOPPED state, substate DOWN.
