Daemon - lsmd DESCRIPTION
libStorageMgmt plug-in daemon. Plug-ins execute in their own process space for fault isolation and to accommodate different plug-in licensing requirements. Runs as an unprivileged user. OPTIONS
--plugindir = The directory where the plugins are located --socketdir = The directory for IPC sockets -v = Verbose logging -d = New style daemon (systemd) non-forking BUGS

picld - PICL daemon SYNOPSIS
/usr/lib/picl/picld The Platform Information and Control Library (PICL) provides a mechanism to publish platform-specific information for clients to access in a platform-independent way. picld maintains and controls access to the PICL information from clients and plug-in modules. The daemon is started in both single-user and multi-user boot mode. Upon startup, the PICL daemon loads and initializes the plug-in modules. These modules use the libpicltree(3PICLTREE) interface to create nodes and properties in the PICL tree to publish platform configuration information. After the plug-in modules are initialized, the daemon opens the PICL daemon door to service client requests to access information in the PICL tree. PICL Tree The PICL tree is the repository of all the nodes and properties created by the plug-in modules to represent the platform configuration. Every node in the PICL tree is an instance of a well-defined PICL class. The name of the base PICL class is picl, which defines a basic set of properties that all nodes in the tree must possess. Two of those properties are name and _class, where name contains the name of the node, and the _class contains the PICL class name of the node. Certain nodes in the PICL tree have well-known names. For example, the name of the root node of the PICL tree is / and the name of the root node of the sub-tree containing platform device nodes is platform. PICL plug-in Modules The PICL plug-in modules are shared objects that publish platform-specific data in the PICL tree. They are located in well-known directo- ries so that the daemon can locate and load them. Plug-in modules are located in one of the following plug-in directories depending on the plaform-specific nature of the data that they col- lect and publish: /usr/platform/`uname -i`/lib/picl/plugins /usr/platform/`uname -m`/lib/picl/plugins A plug-in module can specify its dependency on another plug-in module using the -l or -R linker option. The plug-ins are loaded by the dae- mon using dlopen(3C) according to the specified dependencies. Each plug-in module must define a .init section, which is executed when the plug-in module is loaded, to register themselves with the daemon. See picld_plugin_register(3PICLTREE) for additional information on plug- in registration. The plug-in modules use the libpicltree(3PICLTREE) interface to publish nodes and properties in the PICL tree so that clients can access them. When the PICL daemon invokes the initialization routine of the plug-in module, the plug-in collects the platform information and creates nodes and/or properties to represent the configuration in the PICL tree. A plug-in can create additional threads to monitor the platform configuration and update the PICL tree with any changes. This enables a PICL plug-in to operate as a daemon within the PICL framework. An environmental monitor is an example of a plug-in module that uses a thread to monitor the temperatures and fan speeds of the platform, then publishes the environmental information in the PICL tree so clients can access them. Clients use the libpicl(3PICL) interface to send requests to picld for accessing the PICL tree. picld does not return an exit status. /var/run/picld_door PICL daemon door /usr/lib/picl/picld PICL daemon See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWpiclu | +-----------------------------+-----------------------------+ svcs(1), svcadm(1M), dlopen(3C), libpicl(3PICL), libpicltree(3PICLTREE), picld_log(3PICLTREE), picld_plugin_register(3PICLTREE), attributes(5), smf(5) The picld service is managed by the service management facility, smf(5), under the service identifier: svc:/system/picl Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M).
