Myrinet Monitoring Line Card Can Become Unresponsive |
 |
A Myrinet monitoring line card can become unresponsive
some period of time after it has been set up with an IP address with
DHCP. This is a problem known to Myricom. For more information,
see the following:

If the line card becomes unresponsive, re-seat
the line card by sliding it out of its chassis slot and then slide
it back in. You can do this while the system is up; doing so does
not interfere with Myrinet traffic.
The clear_counters Command Does Not Work On The 256 Port Switch |
|
The /opt/gm/sbin/clear_counters command
does not clear the counters on the Myrinet 256 port switch. The web
interface to the Myrinet 256 port switch has changed from the earlier,
smaller switches.
To clear the switch counters, you must open an
interactive Web connection to the switch and clear the counters using
the menu commands. The gm_prodmode_mon script,
which uses the clear_counters command, will not
clear the counters periodically, as it does on the smaller switches.
This problem will be resolved in a future software
update from Myricom.
