ADD LU Command
If you are using the SNAX/XF access method, enter the name of the associated
SNAX/XF LU. The name you specify must include the SNAX/XF device name.
The form of the name must be:
$snax/xf-name.#lu-name
AUTOSTART { YES | NO }
YES specifies that the local LU is started automatically during the SNAX/APC
process initialization. When SNAX/APC is started and a non-empty configuration
file is specified, all LUs referenced in the file and listed as AUTOSTART will be
automatically started.
Note, however, that an LU is not automatically started when it is first added, even if
the value is YES. The configuration file is updated when an LU is added, but the
value of AUTOSTART is not referenced until subsequent restarts. Therefore, when
an LU is first added, it must be explicitly started with the START LU command.
NO, the default, specifies that the local LU is not started automatically during the
SNAX/APC process initialization. The START LU command must be explicitly
issued.
MAXSESSION number
specifies the maximum number of sessions that the local LU can have, where
number is an integer in the range of 1 to 1024. If the value of MAXSESSION is 1
(the default), the local LU is treated as a single-session LU (an LU that does not
support parallel sessions). If the value of MAXSESSION is greater than 1, the local
LU is treated as a parallel-session LU, and the TPN object named %06F1% and the
PTNR-MODE object named SNASVCMG are added automatically.
You can configure all 32 LUs to have MAXSESSION set to 1024, but no more than
1024 sessions are allowed to be active.
SNAXMAXRETRYCOUNT number
specifies the maximum number of times that SNAX/APC will attempt to open the
access method file after an error occurs. The valid values are from 0 through 32767.
The default value is zero (0), which specifies that no retry will be attempted.
If the specified number of attempts is reached without a successful open of the
SNAX access method, the SNAX/APC LU and its subordinate objects stay in the
STARTING state. SNAX/APC does not attempt to open the underlying SNAX
access method again until a START LU command or a TP-READY verb for that LU
is received.
SNAXRETRYTIMER number
specifies the amount of time in milliseconds before SNAX/APC attempts to reopen
the underlying SNAX access method file (which is the file specified in the
SNAXFILENAME attribute) after an error occurs. The valid values are -1, and from
1 through 86,400,000 (24 hours). The default value is -1, which specifies that the
timer will wait indefinitely (SNAX/APC will not attempt the retry).
