6. Marks the device css0 as defined
There is an undocumented command called
css_restart_node
that runs first the
unconfigure method and then the configure method. This command should only
be run at the request of an IBM engineer as the results can be unpredictable in
certain circumstances.
4.7 Switch Log Files
There are numerous log files associated with the switch, some of which can
provide essential data for resolving switch problems. It is impossible in this
redbook to provide enough information about how to read and interpret these
files. Instead, a brief example is given of what type of data is contained in these
files, along with an example of some typical output. It is not expected that the
reader will be able to resolve all the problems by using these logs, but that the
first level of analysis can be undertaken in most cases prior to contacting the
local IBM Support Center. A utility is provided called
css.snap
which will create
a compressed tar image of all the switch logs in the following format:
/var/adm/SPlogs/css/<hostname>.<date>.css.snap.Z
Run the command:
# dsh -a /usr/lpp/ssp/css/css.snap
Then transfer all the compressed tar images to a single system such as the
Control Workstation to provide the data to the local IBM Support Center.
/var/adm/SPlogs is a specific directory for SP logs. In this directory you will find
the following files:
On the Control Workstation:
•
/var/adm/SPlogs/css/Eclock.log
•
/var/adm/SPlogs/css/Ecommands.log
• /var/adm/SPlogs/sdr/SDR_config.log
•
