DU[MP] L[DEV]
DU[MP] L[DEV]
Captures data pertaining to a specific logical device number and writes
it to a disk file.
Security level: 2.
Syntax
L[DEV] ldevnum
Parameter
ldevnum The logical device number associated with the device
whose data you want to dump.
Description
Information associated with the logical device number is dumped to a
disk file. Since the ldev is also associated with a port, information
pertaining to the port is also dumped. Therefore, if you have identified a
terminal problem and dump information using the ldev subcommand,
complete information about the terminal connection is dumped; there is
no need to also use the PORT subcommand.
NOTE Dumping information pertaining to a logical device number does not
reset (or otherwise affect) the associated device. If you need to reset the
device, use the RESET command.
When the dump is complete, the following information will be
displayed:
The dump file is TRMdddll.PUB.SYS
where ddd is the Julian day of the year and ll is a two-letter string in
the range:
AA, AB, AC, ..., BA, BB, BC, ..., ZZ
This numbering system allows you to create many dump files in one day
and to later know on what day each dump was created by simply
looking at the file name.
The dump prompt is then repeated so that you may enter another dump
subcommand.
