45 *
46 * Description of property groups for service: svc:/system/stmf
47 *
48 * Stability: Volatile
49 *
50 * 1. Property Group: host_groups
51 * Properties: group_name-<N> where <N> is an unsigned integer
52 * type: ustring
53 * contains: group name
54 * group_name-<N>-member_list where <N> is an unsigned
55 * integer matching a group_name-<N> property.
56 * type: ustring
57 * contains: list of members
58 *
59 * Description:
60 * Contains the host group names as well as the host group members
61 * for each host group.
62 *
63 * 2. Property Group: target_groups
64 * Properties: group_name-<N> where <N> is an unsigned integer
65 * type: ustring
66 * contains: group name
67 * group_name-<N>-member_list where <N> is an unsigned
68 * integer matching a group_name-<N> property.
69 * type: ustring
70 * contains: list of members
71 *
72 * Description:
73 * Contains the target group names as well as the target group
74 * members for each target group.
75 *
76 * 3. Property Group: lu-<GUID>
77 * where <GUID> is a 32 character hexadecimal string.
78 * Properties: ve_cnt
79 * type: count
80 * contains: the number of current view entries
81 * view-entry-<N>-<GUID> where <N> is an unsigned integer
82 * type: ustring
83 * contains: nothing. Used as reference to the view
84 * entry property group
85 *
86 * Description:
87 * Contains the references to each view entry. One lu-<GUID>
88 * property group will exist for each logical unit with 1 or more
89 * view entries.
90 * Potentially can hold any other data that can be managed on a per
91 * logical unit basis.
92 *
93 * 4. Property Group: view_entry-<N>-<GUID> (matches property in lu-<GUID>
94 * property group)
95 * Properties: all_hosts
96 * type: boolean
97 * contains: when true, the value of host_group is
98 * ignored
99 * all_targets
100 * type: boolean
101 * contains: when true, the value of target_group is
102 * ignored
103 * host_group
104 * type: ustring
105 * contains: host group for logical unit mapping and
106 * masking purposes
107 * target_group
108 * type: ustring
109 * contains: target group for logical unit mapping and
110 * masking purposes
111 * lu_nbr
112 * type: opaque
113 * contains: the 8-byte SCSI logical unit number for
114 * mapping and masking purposes
115 * Description:
116 * One "view_entry-<N>-<GUID>" property group will exist for each
117 * view entry in the system. This property group name maps
118 * directly to the "lu-<GUID>" property group with a matching
119 * <GUID>.
120 *
121 * 5. Property Group: provider_data_pg_<provider-name>
122 * where <provider-name> is the name of the provider
123 * registered with stmf.
124 * Properties: provider_data_prop-<N>
125 * where <N> is a sequential identifier for the data
126 * chunk.
127 * type: opaque
128 * contains: up to STMF_PROVIDER_DATA_PROP_SIZE bytes
129 * of nvlist packed data.
130 * provider_data_count
131 * type: count
132 * contains: the number of provider data chunks
133 * provider_data_type
134 * type: integer
135 * contains: STMF_PORT_PROVIDER_TYPE or
136 * STMF_LU_PROVIDER_TYPE
137 *
138 * Description:
139 * Holds the nvlist packed provider data set via
140 * stmfSetProviderData and retrieved via stmfGetProviderData. Data
141 * is stored in STMF_PROVIDER_DATA_PROP_SIZE chunks. On retrieve,
142 * these chunks are reassembled and unpacked.
