Table3-2. Setup output files (continued)
File Location Description Directory
css.snap.log All nodes Log files created by the switch
support code /var/adm/SPlogs/css
Table3-3. Tuning output files
File Location Description Directory
daemon.stdout All nodes Keeps a detailed account of the
tuning process initiated by the Estart
command. It includes data from
every tuning operation since the
current daemon on the primary node
was initiated.
/var/adm/SPlogs/css
topology.data Primary Arecord of the primary node, how
many nodes were initialized, and the
links between them.
/var/adm/SPlogs/css
daemon.stderr All nodes Arecord of which nodes were not
initialized. /var/adm/SPlogs/css
out.top Primary Reports errors from the last tuning
procedure. It begins as a copy of the
topology file and errors are
indicated to the right of each entry.
/var/adm/SPlogs/css0/p0
out.top.old Primary A copy of out.top from the previous
run. /var/adm/SPlogs/css0/p0
router.log Primary The router log file generated by the
route table generator after
initialization.
/var/adm/SPlogs/css0/p0
router.log.old Primary A copy of router.log from a previous
run. /var/adm/SPlogs/css0/p0
Using the css.snap script
The css.snap script is located in the /usr/lpp/ssp/css directory. When the script runs, it collects log, trace,
and dump files created by SP Switch2 support code (device driver, worm, fault-service daemon, and
diagnostics) into a single compressed package.
Attention: css.snap uses a number of undocumented utilities to collect information. Some of these can
be destructive when used on a running system. After using css.snap to collect diagnostic information, it’s
best to run /usr/lpp/ssp/css/rc.switch in order to reset and reload the switch adapter and eliminate
residual effects of these utilities. This procedure should be used only under the direction of the IBM
Support Center.
When working with a two-plane SP Switch2 system, add the adapter name to the command, as follows:
dsh -a /usr/lpp/ssp/css/rc.switch -a
<adapter_name>
The css.snap script is called whenever a serious error is detected by the switch support code. Youcan
direct the system to create a snapshot by loging into the desired node and manually issuing the command:
/usr/lpp/ssp/css/css.snap with any of the optional flags: [-c | -n] [-s] [-a cssX (where X=0 or 1)] [-p p0]
where:
v-c Flushes the adapter cache and prints the result. This is the default.
