Managing System Configuration and Memory
Loading specific module images
from tar files. Using the load and loadmate commands, you can also load an extracted
code image or transfer code images between control modules on redundant systems.
If the Stinger FS, Stinger FS+, Stinger LS, or Stinger RT unit contains two control
modules, you must always load the same version of software to both control
modules. Also, unless you specify otherwise, the system defaults to using the
PCMCIA flash card in slot 1 of each control module.
Using the
load-select
profile
The load-select profile enables you to specify which module images to load to flash
when you use a load tar command. For example:
admin> load tar network IPaddress stgrel.tar flash-card-2
After you reset a system, the system creates the
load-select
profile if it is not
present. Each parameter in the
load-select
profile represents a supported module
image and an intended load action for each module type, when the image is present
in a tar file. It also contains an
unknown-cards
parameter, which represents new
modules that were not supported in the previous TAOS release.
When loading the tar file, the system uses settings in the
load-select
profile to load
only specific module images. For a listing of the parameters in the
load-select
profile, see the Stinger Reference . Each parameter in the profile represents a type of
module installed on a Stinger FS, Stinger FS+, Stinger LS, Stinger RT unit, or port
functions on a Stinger MRT.
The setting of the parameter for each module specifies the action that the system
takes when the code image is present in a tar file. The
load-select
profile does not
list the control module code, because that image is always loaded from the updated
tar file. Specify one of the following settings:
auto (the default)—Load images for modules that are installed in the Stinger unit
and skip images for modules that are not installed.
load
—Load the image for the module, even if no module of that type is installed.
skip
—Skip the image for the module, even if a module of that type is installed.
The system determines a module to be present if a
slot-type
profile exists for that
module type. It creates a
slot-type
profile when it first detects the presence of a
module. If you remove that module, the system does not delete the
slot-type
profile
for that module unless you use the
slot -r
command or clear NVRAM. To ensure
that the system does not load unnecessary images, use
slot -r
to remove
slot-type
profiles for modules that are no longer installed in the system. For details, see
“Removing a module and its configuration” on page 2-17.
Loading images for unknown modules
The
unknown-cards
parameter represents any module that was not supported in the
previous release. If you install a new type of module into the Stinger unit before
loading the tar file, the system loads all code images for all unknown modules, which
can cause an overflow in the PCMCIA flash card or built-in flash memory. To prevent
a flash overflow, use the following procedure:
1 Set the
unknown-cards
parameter in the
load-select
profile to
skip
.
