APC Fencing Method "Switch (optional)" param does not default to "1"
Last modified: 2015-04-19 20:47:20 EDT
Description of problem:
Used Conga to configure a cluster. When configuring APC fencing method, leaving
the "Switch (optional)" blank does not default to switch="1". When "Switch
(optional)" is left blank, the cluster.conf file contains no switch="1"
parameter. This causes the fencing to hang. Entering a value in "Switch
(optional)" adds a switch="<n>" parameter.
At first this appeared to be a Conga problem; however it looks like it is a
fence_apc problem. As part of troubleshooting, we used this command first:
fence_apc -a 10.15.90.32 -l apc -p apc -n 1 -v
It did not work.
Running it with the switch number as follows did work:
fence_apc -a 10.15.90.32 -l apc -p apc -n 1:1 -v
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Is this one of your master switch plus units in MSP? I think it is defaulting to
'0' right now, which is obviously the problem. I will jump on this with a fix
today, but please confirm that this is a MSP in Msp that this occurring on ;-)
