specified. If alternate volumes are specified, the dump will be taken on an alternate
volume. If no alternate volumes are specified, TFDS selects the disk drive with the
largest amount of free space and generates the dump.)
ALTERNATE VOLUMES DISALLOWED
does not let TFDS select another drive if the first one does not have the specified
amount of free space. In this case, no dump is taken, and the processor remains
down. You must either issue a new DUMPVOLUME command to specify another
drive or allow alternate volumes, or clear space and use the ANALYZE CPU n
command to restart the process of analyzing and dumping the processor.
Guidelines
•
You can use the abbreviation dv in place of DUMPVOLUME.
•
No volume, percentage, or alternate volume is specified in the default setting.
•
If no volume is specified, the value is reset to Not Assigned. When the volume is
Not Assigned, TFDS searches the ALTERNATE-VOLUMES set for an alternate
volume to dump on. If no alternate volumes are specified with the ALTERNATE-
VOLUMES command, TFDS searches for the disk drive with the largest amount of
free space during run time and uses it to generate the dump.
•
If the volume specified does not exist, TFDSCOM retains the current value and
returns an error message.
•
To determine the current specified volume, use the CONFIG command described
on page 4-14.
Example
This example defines the volume $ALPHA as the volume for TFDS activity:
DUMPVOLUME $ALPHA 10 ALTERNATE VOLUMES ALLOWED
If $ALPHA has less than 10 percent of free disk space, the memory dump is placed in
the volume that has the most free disk space.
ENABLECPUS
The ENABLECPUS command lets you enable the dumping and reloading of specific
processors if a software-related CPU DOWN event occurs.
n
specifies a valid processor number. Processor numbers range from 0 through 15.
ENABLECPUS { n [, n, ... ] | ALL }
