A Configuration Options
The following list shows all possible configuration settings that can be used to change system behaviour. To
change these, use the file /etc/cm.cfg.
The following list shows all available settings with a short explanation.
Table A-1: CM configuration file settings
Setting Default Description
auto_config_file.N
auto_board_manufacturer.N
auto_board_part_number.N
auto_board_name.N
auto_product_manufacturer.N
auto_product_part_number.N
auto_product_name.N
N/A
Load config file auto_config_file.N if any of the strings set
in auto_board_X.N or auto_product_X.N matches the corre-
sponding board info area or product info area field of the
chassis backplane FRU data or if it is not set in the config file
(i.e. “”)
These settings can be used to create a number of auto con-
figuration settings that are loaded for specific backplanes.
Note that not all settings are valid when auto_config_file.N
gets loaded, as basic initialisation has already been fin-
ished. But selecting chassis implementations (e.g.
pm_om6060) and other settings are possible.
auto_detect_config 1
0=disable autodetection of configuration settings as defined
by auto_config_file.N etc settings.
1=enable automatic loading of configuration files based on
auto_config_file.N etc settings
bg_num_threads 4
Max. number of background threads for BG processing rou-
tines
cli_ro_users “”
list of Unix users that can access only read-only CLI com-
mands using clicm
cli_rw_users root
list of Unix users that can access read-write commands using
clicm
cm_activation_readiness 0
If set overrides the the activation readiness value found in
carrier FRU data information
cm_enable_pcie_clock_when_pcie
_present
1
1=enable PCI Express to slot when AMC that has PCI Express
capability described in FRU data is enabled for payload
power
0=CM does not manage PCI Express clock
Note: This setting only works when MCH is also active carrier
manager. For redundant configurations, PCI Express clocks
should always be managed by AMC Clock E-Keying, which is
not supported in SW version BETA 1.02 and earlier
cm_fake_quiesced.N 0
Do not wait for the module with FRU id N to send a quiesced
event. Assumes that module is quiesced when the response
to the FRUControl(Quiesce) command is received
cm_ignore_fru_merge_err.N 0
Ignore FRU merge errors during module activation for FRU id
N
cm_ignore_handle.N 0
Used to force CM to ignore handle status from this module
with FRU id N. Needed for example for power modules that
have no handle sensor implemented or always report handle
open.
cm_ignore_sens_merge_err.N 0
Ignore SDR merge errors during module activation for this
FRU
