- * This file's functions are responsible for all store and retrieve operations
- * against the STMF smf(5) database. The following shows the currently defined
- * schema for the STMF database:
- *
- * Description of property groups for service: svc:/system/stmf
- *
- * Stability: Volatile
- *
- * 1. Property Group: host_groups
- * Properties: group_name-<N> where <N> is an unsigned integer
- * type: ustring
- * contains: group name
- * group_name-<N>-member_list where <N> is an unsigned
- * integer matching a group_name-<N> property.
- * type: ustring
- * contains: list of members
- *
- * Description:
- * Contains the host group names as well as the host group members
- * for each host group.
- *
- * 2. Property Group: target_groups
- * Properties: group_name-<N> where <N> is an unsigned integer
- * type: ustring
- * contains: group name
- * group_name-<N>-member_list where <N> is an unsigned
- * integer matching a group_name-<N> property.
- * type: ustring
- * contains: list of members
- *
- * Description:
- * Contains the target group names as well as the target group
- * members for each target group.
- *
- * 3. Property Group: lu-<GUID>
- * where <GUID> is a 32 character hexadecimal string.
- * Properties: ve_cnt
- * type: count
- * contains: the number of current view entries
- * view-entry-<N>-<GUID> where <N> is an unsigned integer
- * type: ustring
- * contains: nothing. Used as reference to the view
- * entry property group
- *
- * Description:
- * Contains the references to each view entry. One lu-<GUID>
- * property group will exist for each logical unit with 1 or more
- * view entries.
- * Potentially can hold any other data that can be managed on a per
- * logical unit basis.
- *
- * 4. Property Group: view_entry-<N>-<GUID> (matches property in lu-<GUID>
- * property group)
- * Properties: all_hosts
- * type: boolean
- * contains: when true, the value of host_group is
- * ignored
- * all_targets
- * type: boolean
- * contains: when true, the value of target_group is
- * ignored
- * host_group
- * type: ustring
- * contains: host group for logical unit mapping and
- * masking purposes
- * target_group
- * type: ustring
- * contains: target group for logical unit mapping and
- * masking purposes
- * lu_nbr
- * type: opaque
- * contains: the 8-byte SCSI logical unit number for
- * mapping and masking purposes
- * Description:
- * One "view_entry-<N>-<GUID>" property group will exist for each
- * view entry in the system. This property group name maps
- * directly to the "lu-<GUID>" property group with a matching
- * <GUID>.
- *
- * 5. Property Group: provider_data_pg_<provider-name>
- * where <provider-name> is the name of the provider
- * registered with stmf.
- * Properties: provider_data_prop-<N>
- * where <N> is a sequential identifier for the data
- * chunk.
- * type: opaque
- * contains: up to STMF_PROVIDER_DATA_PROP_SIZE bytes
- * of nvlist packed data.
- * provider_data_count
- * type: count
- * contains: the number of provider data chunks
- * provider_data_type
- * type: integer
- * contains: STMF_PORT_PROVIDER_TYPE or
- * STMF_LU_PROVIDER_TYPE
- *
- * Description:
- * Holds the nvlist packed provider data set via
- * stmfSetProviderData and retrieved via stmfGetProviderData. Data
- * is stored in STMF_PROVIDER_DATA_PROP_SIZE chunks. On retrieve,
- * these chunks are reassembled and unpacked.
