Red Hat Bugzilla – Bug 126676
WTI NPS STONITH driver doesn't function properly when certain switch parameters are altered
Last modified: 2009-04-16 16:15:04 EDT
Description of problem: If you turn on automated mode and telnet to a TPS/IPS/NPS switch, it drops you to a prompt immediately; the same happens if you turn off "Confirmation". That is, no "status screen" is displayed upon login. The STONITH driver times out waiting for the header from the statu screen describing which product it is connected to (e.g. "Network Power Switch", "Telnet Power Switch", etc.). After it times out, it returns S_BADCONFIG. How to get it working: Log in to the power switch and enter the "General Settings" menu with the "/G" command. (1) Ensure that "Automated Mode" is "Off". (2) Ensure that "Confirmation Confirmation" is "On".
This behavior is not worth fixing, as it can be solved by altering the switch's configuration.
As an additional note for this bugzilla: The "Boot Delay" for each plug should be left at the 5 second default. Cross-reference: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=108393
When configuring the WTI power switch, it's important to note that the "port" field in redhat-config-cluster is the port name on the *power switch*, not the TCP port number. That is, the port name should be "1", "2"... "8", or the corresponding symbolic name, not the TCP port number which telnet uses. The STONITH driver already knows that it needs to connect to port 23.
