it_tpg_create(3ISCSIT)iSCSI Management Library Functionsit_tpg_create(3ISCSIT)NAME
it_tpg_create, it_tpg_delete, it_tpg_free - create and delete
iSCSI target portal groups
SYNOPSIS
cc [ flag... ] file... -liscsit [ library... ]
#include <libiscsit.h>
int it_tpg_create(it_config_t *cfg, it_tpg_t **tpg,
char *tpg_name, char *portal_ip_port);
int it_tpg_delete(it_config_t *cfg, it_tpg_t *tpg,
boolean_t force););
void it_tpg_free(it_tpg_t *tpg);
PARAMETERS
cfg a pointer t the iSCSI configuration structure
tpg a pointer to the it_tpg_t structure representing the
target portal group
tpg_name an identifier for the target portal group
portal_ip_port a string containing an appropriately formatted IP
address:port. Both IPv4 and IPv6 addresses are per‐
mitted. This value becomes the first portal in the
target portal group. Applications can add additional
values using it_portal_create(3ISCSIT) before commit‐
ting the target portal group. IPv6 addresses should
be enclosed in square brackets ('[', ']').
force boolean value indicating if the target portal group
should be removed even if it is associated with one
or more targets. If not B_TRUE, the operation will
fail if the target product group is associated with a
target.
DESCRIPTION
The it_tpg_create() function allocates and creates an it_tpg_t struc‐
ture representing a new iSCSI target portal group. The new it_tpg_t
structure is added to the global tpg list (cfg_tgt_list) in the it_con‐
fig_t structure.
The it_tpg_delete() function deletes the target portal group repre‐
sented by tpg, where tpg is an existing it_tpg_t structure within the
global configuration cfg.
The it_tpg_free() function deallocates resources associated with an
it_tpg_t structure. If tpg->next is not NULL, this function frees all
members of the list.
Configuration changes as a result of these functions are not instanti‐
ated until the modified configuration is committed by calling it_con‐
fig_commit(3ISCSIT).
RETURN VALUES
The it_tpg_create() and it_tpg_delete() functions return 0 on success
and an error value on failure.
ERRORS
The it_tpg_create() and it_tpg_delete() functions will fail if:
EBUSY The portal group is associated with one or more targets.
EEXIST The portal was already configured for another portal group
associated with this target.
EINVAL A parameter is invalid.
ENOMEM Resources could not be allocated.
