NAME

it_config_load, it_config_commit, it_config_setprop, it_config_free - set and retrieve configuration data for the iSCSI Target Port Provider
 

SYNOPSIS

cc [ flag... ] file... -liscsit [ library... ]
#include <libiscsit.h>

int it_config_load(it_config_t **cfg);

int it_config_commit(it_config_t *cfg);

int it_config_setprop(it_config_t *cfg, nvlist_t *proplist,
    nvlist_t **errlist);

void it_config_free(it_config_t *cfg);

PARAMETERS

cfg

a pointer to the iSCSI configuration structure

proplist

a pointer to an nvlist_t containing the global properties to be set

errlist

an optional pointer to an nvlist_t that will be used to store specific errors (if any) when validating global properties

DESCRIPTION

The it_config_load() function allocates and creates an it_config_t structure representing the current iSCSI configuration. This structure is compiled using the "provider" data returned by stmfGetProviderData(3STMF). If there is no provider data associated with iscsit, the it_config_t structure is set to a default configuration.

The it_config_commit() function informs the iscsit service that the configuration has changed and commits the new configuration to the persistent store by calling stmfSetProviderData(3STMF). This function can be called multiple times during a configuration sequence, if necessary.

The it_config_setprop() function validates the provided property list and sets the global properties for iSCSI Target. If errlist is not NULL, this function returns detailed errors for each property that failed. The format for errorlist is key = property, value = error string.

The it_config_free() function frees resources associated with the it_config_t structure.

Global nvlist properties are as follows:

nvlist Key	Type	Valid Values
alias	string	any string
auth
isns
isnsserver
radiusserver
radiussecret

RETURN VALUES

The it_config_load(), it_config_commit(), and it_config_setprop() functions return 0 on success and an error value on failure.  

ERRORS

The it_config_load(), it_config_commit(), and it_config_setprop() functions will fail if:

EINVAL

A parameter or property is invalid.

ENOMEM

Resources could not be allocated.

The it_config_commit() function will also fail if:

STMF_ERROR_SERVICE_DATA_VERSION

The configuration was updated by another client. See stmfSetProviderData(3STMF).
