Configuration

Configuration files

Configuration is stored in /etc/openlmi/storage/storage.conf and /etc/openlmi/openlmi.conf. storage.conf is parsed first and only missing options are parsed from openlmi.conf.

File format

This file has simple .ini syntax, with # or ; used for comments.

Default configuration:

[CIM]
Namespace=root/cimv2
SystemClassName=PG_ComputerSystem

[Log]
Level=ERROR
Stderr=false
DebugBlivet=false

Section	Option name	Default value	Desciption
CIM	Namespace	root/cimv2	Namespace where OpenLMI-Storage providers are registered.
CIM	SystemClassName	PG_ComputerSystem	Name of CIM_ComputerSystem class, which is used to represent the computer system. It will be used as SystemClassName property value of various classes.
Log	Level	ERROR	Chooses which messages are logged, either to CIMOM and (if configured) to standard error output. Available levels (sorted by severity) are: CRITICAL ERROR WARNING INFO DEBUG TRACE_WARNING TRACE_INFO TRACE_VERBOSE Levels below INFO (= TRACE_WARNING, TRACE_INFO and DEBUG) are useful mainly for debugging and bug reporting.
Log	Stderr	false	Toggles sending of log messages to standard error output of the CIMOM.
Log	DebugBlivet	false	Toggles logging of detailed debug messages in Blivet.
Storage	Tempdir	/tmp	Path to temporary directory. The providers (usually running as root) need read/write access there. When SELinux or other security enhancement mechanism is used, only the provider should have read/write access to this directory.

Persistent setting

OpenLMI-Storage stores persistent data in /var/lib/openlmi-storage/. Typically, various CIM_SettingData instances with ChangeableType Changeable - Persistent are stored here.

Logging

By default, all log messages with level INFO and above are sent to CIMOM using standard CMPI CMLogMessage function. Consult documentation of your CIMOM how to enable output of these messages into CIMOM logs.

With Stderr configuration option enabled, all logs are sent both to CIMOM and to the standard error output of the CIMOM.

Messages with TRACE_WARNING and below are sent to CIMOM using CMTraceMessage and should be visible in CIMOM tracing log. Again, please consult your CIMOM documentation how to enable tracing logs.
