ALTER LU Command
You are limited in the number of attributes you may change when working with dynamic
objects. See the individual ALTER <object-type> commands.
ALTER LU Command
The ALTER LU command changes the attribute settings of the specified LU.
ALTER LU Attributes
The attribute specification for the LU object of the SNAX/APC ALTER command
consists of the following attribute name and value combinations:
LIKE local-lu2
identifies an existing local LU whose attribute values serve as the model for the new
values of the attributes of the local LU being altered.
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 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 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
ALTER [ LU local-lu1 ] [, LIKE local-lu2 ] [, attribute-spec
]
where attribute-spec is:
[ , AUTOSTART { YES | NO } ]
[ , MAXSESSION number ]
[ , SNANAME uninterpreted-lu-name ]
[ , SNAXFILENAME access-method-subdevice-name ]
[ , SNAXMAXRETRYCOUNT number ]
[ , SNAXRETRYTIMER number ]
[ , DYNAMICSUPPORT {YES | NO} ]
[ , LOCAL-LU-SYNC2-SUPPORT { NONE | SYNCPT } ]
