I'm running RHEL 5 on a few machiens trying to implement clustering.
I'm at the part of getting fencing to work. I have fencing working with
my Brocade Fibre switches and now I'm setting up fencing with my APC
AP7941 PDUs.
I suspect there is a bug in the fence_apc code for my specific AOS & APP
version:
Network Management Card AOS: v3.5.6
Rack PDU APP: v3.5.5
fence_apc shows a version of 2.0.84 with a builddate of Tue Sep 9
16:28:58 EDT 2008
I've attached the log file generate by fence_apc below.
It seems like this specific version of the AOS & APP isn't supported.
What is happening is the script successfully logs into the PDU, then
issues the command "1" correctly. It then determines the FIRMWARE_REV
(as v3) then issues two commands at once "2" followed by "3". Using the
other firmware option, it only submits one command "3". Because of this
on its next step of submitting the outlet number, it thinks its at a
different position than it really is (because it hasn't parsed all the
output of executing both commands) at the same time. It then gets
caught in an endless loop of trying to execute a command.
I can see this in the function do_power_switch in fence_apc. I've
googled around and haven't seen any information related to this, so I
think I found a bug.
Is anyone else using fence_apc with this specific PDU? I have fencing
working with the fibre switches, but not sure if I need a backup fencing
device.
(I know I'm starting to ramble but its really clear in my head, I swear)
