G.2.10 Procedure for network device maintenance

If you stop the ping monitoring destination network device for maintenance, GLS may detect a network failure. Also, if a cluster configuration is in use, node failures may occur. When you perform network device maintenance, be sure to notify other persons in charge that you are going temporarily stop monitoring.

Confirmation method

In a cluster configuration environment, if you want to stop all monitoring destinations for network device maintenance, check the maintenance procedure manual to see that the "hanetpoll off" command for temporarily stopping monitoring is set to be executed. Also, check that the "hanetpoll on" command is used to restart the monitoring after change.

Before the network device is changed
# /opt/FJSVhanet/usr/sbin/hanetpoll off
After the network device has been changed
# /opt/FJSVhanet/usr/sbin/hanetpoll on
