A user space configuration program (asd_ctl) is included in the release package and is 

run automatically as part of the load script.

The configuration file /etc/icp_asd.conf is a simple configuration file containing the 

user-specified system resource variables and the values to be read into / set by the 

kernel in the configuration table.

The syntax for updating the configuration file is as follows:

# comment
token = value 
token = value # comment

Blank lines are ignored and white spaces before and after a token or value are ignored.

Comments are denoted by the ‘#’, any text read after a # symbol is ignored.

If the same system resource variable is specified more than once in the configuration 

file, the last value read will be the one which is set in the configuration table.

A warning message will be printed if invalid syntax in the configuration file is 

encountered. The default values will be applied to all system resource variables that are 

not specified in the configuration file.

If an invalid value is specified for a system resource variable, a warning message will 

be printed and the default value will be applied.

Refer to 

 for a list of system resource variables that can be configured in 

the /etc/icp_asd.conf configuration file.
