UNIX Host on the LAN
When troubleshooting a UNIX host on the LAN, make sure that:
•
The host is booted and functioning properly.
•
The host can communicate with other network nodes using
standard UNIX networking features and utilities.
•
All RAC software is installed properly on the host. Refer to
Installing Remote Access Concentrator Software for UNIX
for procedures to properly install the software.
•
The erpcd daemon or tftp server (which loads the
operational image to the RAC) is running.
In Test mode, erpcd on the load server host displays boot progress reports.
In Monitor mode, the RAC displays boot progress reports. The RAC
displays its reports on the console terminal that invokes its Monitor mode;
erpcd displays its reports on the UNIX workstation that invokes its Test
mode.
When running erpcd, all paths are relative to the /usr/spool/erpcd/bfs
directory for both boots and dumps. The /usr/spool/erpcd/bfs directory
is the default path name and can be changed.
To trouble shoot a UNIX host on the LAN:
1.
Place erpcd on the load server host into Test mode by killing
the erpcd program (requires superuser privileges) and
restarting it using the –D5 option:
# /usr/annex/erpcd –D5
Running erpcd with the -D5 option invokes a very
thorough debug mode that can take a considerable
amount of time to complete.
2.
Put the RAC into Monitor mode. (This resets the RAC, so
warn users before you do this.)
3.
At the monitor prompt, enter:
monitor:: boot -v
