mod_kernel += "tunable name value"
mod_kernel += "module name [state]"
The first performs the same as it did previously with the addition of the keyword tunable. The
second describes how kernel modules are added to the client. The optional state argument has one
of four values: static, auto, loaded and best. No syntax checking is performed for this
value. See kcmodule(1M) for more information.
Actions involving mod_kernel are performed before those for both set_kernel and
rm_kernel.
Note: Spaces should only be used within strings associated with *kernel keywords. Tabs are
not acceptable characters.
set_kernel = cplx-string
set_kernel += cplx-string
Setting this keyword is the same for drivers as the mod_kernel keyword in that it adds the
driver to the kernel. For tunables it differs from mod_kernel in that it sets the tunable to an
arbitrary value as defined by cplx-string. No comparisons or checks are performed with prior or
default values. Actions involving set_kernel are performed after those for mod_kernel,
but before those for rm_kernel.
Note: Spaces should only be used within strings associated with *kernel keywords. Tabs are
not acceptable characters.
rm_kernel = cplx-string
rm_kernel += cplx-string
Setting this keyword removes the driver or tunable from the /stand/system file. For drivers,
this implies that the driver is removed from the kernel. For tunables, this implies the tunable
reverts back to its default value. Actions involving rm_kernel are performed after those for
both mod_kernel and set_kernel.
Note: Spaces should only be used within strings associated with *kernel keywords. Tabs are
not acceptable characters.
vxvm_hostid = cplx_string
Setting this identifier writes it to all VxVM disks on a client when they are first added to a disk
group. When a client starts, it looks at all the disks and compares its VxVM identifier to the identi-
fier stored in /etc/vx/volboot. For each disk that matches that identifier, the client enables
access.
vxvm_version = cplx_string
This keyword causes all VxVM disk groups on a client to be created with the on-disk data struc-
tures for the VxVM version specified. The allowable values as well as the defaults in cases where
this keyword is not specified are defined as follows:
HP-UX release Default Allowed
B.11.11 3.5 3.5
B.11.23 3.5 3.5, 4.1, 5.0
B.11.31 4.1 4.1, 5.0
This keyword is applied globally and cannot be set on a per-disk group basis. Valid values for
vxvm_version currently are: "3.5", "4.1", and "5.0".
If vxvm_version is encountered multiple times in a configuration during a cold install, the lowest value
of the keyword will be used as the global value.
The behaviour of this keyword is slightly different during a recovery. The save_config command cre-
ates the configuration file that describes any VxVM disk groups that will be recreated during a recovery.
This command sets vxvm_version
to the highest VxVM version used to create a disk group presented
to the system it is running on.
