PATHMON Environment Control Commands
NonStop TS/MP System Management Manual—541819-001
11- 4
CONTROL PATHMON Command
11 times, 2 minutes if stopped 12 times, and so forth. However, the PATHMON
process does not delay creating a backup process if any of these occur:
°
The processor in which the PATHMON primary or backup process is executing
fails.
°
A PATHCOM SWITCH command is executed.
°
A CONTROL PATHMON BACKUPCPU command is executed.
In addition to not delaying the creation of a backup process if the preceding
conditions occur, the PATHMON process resets its internal counter.
Consequently, creation of a backup process has to fail again 10 more times before
the PATHMON process delays creating the backup process.
•
It is recommended that DUMP be set to ON for production systems. Having a
DUMP file available greatly enhances your ability to solve system problems, and is
a likely requirement when requesting help from your HP representative.
•
If you encounter system problems and the PATHMON process has not created a
dump (because DUMP was not set to ON), use the DUMPMEMORY option to
force a dump.
Errors
This table lists the most common errors that can occur during the processing of the
CONTROL PATHMON command:
Examples
This command creates a backup PATHMON process in processor 5:
CONTROL PATHMON, BACKUPCPU 5
This command changes the PATHMON DUMP option to OFF:
CONTROL PATHMON, DUMP OFF
This Message… Is Displayed When…
*1093* BACKUP PROCESSOR DOWN For a multiprocessor system, you specified a
backup processor that does not exist or is not
operational.
For a single processor system, you included the
BACKUPCPU attribute.
*1095* ILLEGAL CPU NUMBER You specified for the BACKUPCPU attribute the
same processor in which the PATHMON primary
process is running. The location of the backup
process is not changed in this case.
