The following example shows usage of the
xtdumpsys
command:
crayadm@smw>
xtdumpsys --add r0s2c1
The
xtdumpsys
command is written in Python and supports plug-ins written in Python. A number of plug-in
scripts are included in the software release. Call
xtdumpsys --list
to view a list of included plug-ins and their
respective directories. The
xtdumpsys
command also now supports the use of configuration files to specify
xtdumpsys
presets, rather than entering them via the command line.
For more information, see the
xtdumpsys(8)
man page.
3.4.15 Collect Debug Information From Hung Nodes Using the xtnmi Command
CAUTION: This is not a harmless tool to use to repeatedly get information from a node at various times;
only use this command when debugging data from nodes that are in trouble is needed. The
xtnmi
command output may be used to determine problems such as a core hang.
xtnmi
will stop a running
node. It is best used when a node is not running correctly and debugging information is needed, or to stop
a node that is running incorrectly.
The sole purpose of the
xtnmi
command is to collect debug information from unresponsive nodes. As soon as
that debug information is displayed to the console, the node panics.
For additional information, see the
xtnmi(8)
man page.
An example of using the
xtnmi(8)
command is:
smw$
xtnmi r0s1c0n4,r0s0c1s2
The following ID(s) will be NMI'd: r0s1c0n4,r0s0c1s2.
All expected responses (1) were received.
3.4.16 Find Node Information
Translate Between Physical ID Names and Integer NIDs
To translate between physical ID names (rnames) and integer NIDs, generate a system map on the System
Management Workstation (SMW) and filter the output, enter the following command:
crayadm@smw>
rtr --system-map | grep rname | awk '{ print $1 }'
For more information, see the
rtr(8)
man page.
Find Node Information Using the
xtnid2str
Command
The
xtnid2str
command converts numeric node identification values to their physical names (cnames). This
allows conversion of Node ID values, ASIC NIC address values, or ASIC ID values.
For additional information, see the
xtnid2str(8)
man page.
