LU 6.2 Information

Information on LUs is provided in the lu62_info_sect structure as defined below.

typedef struct lu62_info_sect {
    unsigned long  lu62_init_sect_len;
    unsigned short num_lu62s;
    unsigned short total_lu62s;
} LU62_INFO_SECT;

Members

lu62_init_sect_len: Structure length.
num_lu62s: Number of configured LUs displayed.
total_lu62s: Total number of configured LUs.

For each configured LU, an lu62_overlay structure is provided as defined below.

typedef struct lu62_overlay {
    unsigned long  lu62_entry_len;
    unsigned long  lu62_overlay_len;
    unsigned char  lu_name[8];
    unsigned char  lu_alias[8];
    unsigned short num_plus;
    unsigned char  fqlu_name[17];
    unsigned char  default_lu;
    unsigned char  reserv3;
    unsigned char  lu_local_addr;
    unsigned short lu_sess_lim;
    unsigned char  max_tps;
    unsigned char  lu_type;
} LU62_OVERLAY;

Members

lu62_entry_len: Size of this LU entry.
lu62_overlay_len: This value contains sizeof(struct lu62_overlay)–sizeof(lu62_entry_len).
lu_name: LU name (EBCDIC type A).
lu_alias: LU alias (ASCII).
num_plus: Number of partner LUs.
fqlu_name: Fully qualified LU name (EBCDIC type A).
default_lu: For local LU group, an LU equal to the default_lu is used if none is specified. Legal values are AP_NO and AP_YES.
For SNA Server, there is no concept of a default local LU. Therefore, the default_lu flag, which is set to AP_YES for the node in IBM ES for OS/2 version 1.0, is set to AP_NO for SNA Server.
lu_local_addr: NAU address, 0–254.
lu_sess_lim: Configured session limit, 0–255.
max_tps: Maximum number of TPs, 1–255.
lu_type: Always LU type 6.2.

For each configured LU, a plu_62_overlay structure for the partner LU is provided as defined below.

typedef struct plu62_overlay {
    unsigned long  plu62_entry_len;
    unsigned long  plu62_overlay_len;
    unsigned char  plu_alias[8];
    unsigned short num_modes;
    unsigned char  plu_un_name[8];
    unsigned char  fqplu_name[17];
    unsigned char  reserv3;
    unsigned char  plu_sess_lim;
    unsigned char  dlc_name[8];
    unsigned char  adapter_num;
    unsigned char  dest_addr_len;
    unsigned char  dest_addr[32];
    unsigned int   par_sess_supp:1;
    unsigned int   reserv4:7;
    unsigned int   def_already_ver:1;
    unsigned int   def_conv_sec:1;
    unsigned int   def_sess_sec:1;
    unsigned int   reserv5:5;
    unsigned int   act_already_ver:1;
    unsigned int   act_conv_sec:1;
    unsigned int   reserv6:6;
    unsigned int   implicit_part:1;
    unsigned int   reserv7:7;
} PLU62_OVERLAY;

Members

plu62_entry_len: Size of this partner LU entry.
plu62_overlay_len: This value contains sizeof(struct plu62_overlay)–sizeof(plu62_entry_len).
plu_alias: Partner LU alias (ASCII).
num_modes: Number of modes.
plu_un_name: Partner LU uninterpreted name (EBCDIC).
fqplu_name: Fully qualified partner LU name (EBCDIC type A).
plu_sess_lim: Partner LU session limit, 0–255.
dlc_name: DLC name (ASCII).
adapter_num: DLC adapter number.
dest_addr_len: Length of destination adapter address.
dest_addr: Destination adapter address.
par_sess_supp: Bit 15 of a bitfield specifying parallel sessions. Valid values are AP_NOT_SUPPORTED and AP_SUPPORTED.
def_already_ver: Bit 7 of a bitfield specifying whether the configured already verified option is supported. Valid values are AP_NOT_SUPPORTED and AP_SUPPORTED.
def_conv_sec: Bit 6 of a bitfield specifying whether the configured conversation security option is supported. Valid values are AP_NOT_SUPPORTED and AP_SUPPORTED.
def_sess_sec: Bit 5 of a bitfield specifying whether the configured session security option is supported. Valid values are AP_NOT_SUPPORTED and AP_SUPPORTED.
act_already_ver: Bit 15 of a bitfield specifying whether the active already verified option is supported. Valid values are AP_NOT_SUPPORTED and AP_SUPPORTED.
act_conv_sec: Bit 14 of a bitfield specifying whether the active conversation security option is supported. Valid values are AP_NOT_SUPPORTED and AP_SUPPORTED.
implicit_part: Bit 7 of a bitfield specifying whether this is an implicit partner. Valid values are AP_NO and AP_YES.
For partner LU group, implicit_part indicates the partner LU group was configured as an implicit primary logical unit (PLU).

Remarks

SNA Server returns information on all the configured LU 6.2s in the system, including the implicit PLU and all instances of implicit modes. IBM ES for OS/2 version 1.0 only returns information on those that are in use or have been in use.

For partner LU group, implicit_part indicates the partner LU group was configured as an implicit primary logical unit (PLU).

For mode group, implicit_mode bitfield returned in the mode_overlay structure indicates the mode group was configured as an implicit mode.
