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 permitted. This value becomes the first portal in the target portal group. Applications can add additional values using it_portal_create(3ISC- SIT) before committing 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 structure 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_config_t structure. The it_tpg_delete() function deletes the target portal group represented 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 instantiated 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. ATTRIBUTES

NAME
it_tgt_create, it_tgt_setprop, it_tgt_delete, it_tpgt_create, it_tpgt_delete, it_tgt_free, it_tpgt_free - create, modify and delete iSCSI Targets SYNOPSIS
cc [ flag... ] file... -liscsit [ library... ] #include <libiscsit.h> int it_tgt_create(it_config_t **cfg, it_tgt_t **tgt, char *tgt_name); int it_tgt_setprop(it_config_t *cfg it_tgt_t *tgt, nvlist_t *proplist, nvlist_t **errlist); int it_tgt_delete(it_config_t *cfg, it_tgt_t *tgt, boolean_t force); int it_tpgt_create(it_config_t *cfg, it_tgt_t *tgt, it_tpgt_t **tpgt, char *tpg_name, uint16_t tpgt_tag); void it_tpgt_delete(it_config_t *cfg, it_tgt_t *tgt, it_tpgt_t *tpgt); void it_tgt_free(it_tgt_t *tgt); void it_tpgt_free(it_tpgt_t *tpgt); PARAMETERS
cfg a pointer to the iSCSI configuration structure tgt a pointer to an iSCSI target structure tgt_name the target node name for the target to be created. The name must be in either IQN or EUI format. If this value is NULL, a node name will be generated automatically in IQN format. proplist a pointer to an nvlist_t containing the target properties to be set errlist an optional pointer to an nvlist_t that will be used to store specific errors (if any) when validating target properties force a boolean value indicating if the target should be set to offline before removing it from the configuration. If not specified, the operation will fail if the target is determined to be online tpgt a pointer to a target portal group tag structure tpgt_name the name of the target portal group to be associated with this target portal group tag tpgt_tag a 16-bit numerical identifier for this target portal group tag. Valid values are 2 through 65535. If tpgt_tag is '0', it_tpgt_create() will assign an appropriate tag number. If tpgt_tag is != 0, and the requested tag number is unavailable, another value will be chosen. DESCRIPTION
The it_tgt_create() function allocates and creates an it_tgt_t structure representing a new iSCSI target node. If tgt_name is NULL, then a unique target node name will be generated automatically. Otherwise, the value of tgt_name will be used as the target node name. The new it_tgt_t structure is added to the target list (cfg_tgt_list) in the configuration structure. The it_tgt_setprop() function validates the provided property list and sets the properties for the specified target. If errlist is not NULL, this function returns detailed errors for each property that failed. The format for errlist is key = property, value = error string. The it_tgt_delete() function removes the target represented by tgt from the configuration. The tgt argument is an existing it_tgt_t struc- ture within the configuration cfg. The it_tpgt_create() function allocates and creates an it_tpgt_t structure representing a new iSCSI target portal group tag. The new it_tpgt_t structure is added to the target tpgt list (tgt_tpgt_list) in the it_tgt_t structure. The it_tpgt_delete() function removes the target portal group tag represented by tpgt, from the configuration. The tpgt argument is an existing is_tpgt_t structure within the target tgt. The it_tgt_free() function frees an it_tgt_t structure. If tgt->next is not NULL, this function frees all structures in the list. The it_tpgt_free() function deallocates resources of an it_tpgt_t structure. If tpgt->next is not NULL, this function frees all members of the list. Configuration changes as a result of these functions are not instantiated until the modified configuration is committed by calling it_con- fig_commit(3ISCSIT). Target nvlist properties are as follows: nvlist Key Type Valid Values ------------------------------------------------------------------- targetchapuser string any string, or none to remove targetchapsecret string string of at least 12 characters but not more than 255 characters. secret will be base64 encoded when stored. alias string any string or none to remove auth string radius, chap, or none RETURN VALUES
The it_tgt_create(), it_tgt_setprop(), it_tgt_delete(), it_tpgt_create(), and it_tpgt_delete() functions return 0 on success and an error value on failure. ERRORS
The it_tgt_create(), it_tgt_setprop(), it_tgt_delete(), it_tpgt_create(), and it_tpgt_delete() functions will fail if: E2BIG All tag numbers are already in use. EBUSY The target is online. EEXIST The requested target node name is already configured. EINVAL A parameter or property is invalid. ENOMEM Resources could not be allocated. ATTRIBUTES
