Description Hans Middelhoek 2015-09-02 09:49:07 UTC

Description of problem:
We updated the firmware of our APC's (AP8653) to version 6.3.3 but now fencing doesn't work anymore.

Version-Release number of selected component (if applicable):
# fence_apc -V
4.0.10 (built Fri Jun 26 18:24:07 CEST 2015)

How reproducible:
# fence_apc -a xxx.xxx.xxx.xxx -l fenceuser -p pass -x -n 1 --ssh-options="-2 -c blowfish" --power-wait=10 -o status -c "apc>" -vvv

Actual results:
Command doesn't work because old commands are send. The check for firmware version 5.x doesn't match for this newer 6.x firmware and therefore falls back to pre 5.x commands.

Expected results:
Port status should be reported by above command. The olStatus command should be send by fence_apc.

Additional info:
A simple change in fence_apc solves the problem.
Replace this line:
if (firmware_version != None) and (firmware_version.group(1) == "5"):
by this:
if (firmware_version != None) and (firmware_version.group(1) >= "5"):

This will check for firmware version 5.x and newer and solves our problem.

Comment 2 Marek Grac 2015-09-02 12:10:52 UTC

@Hans:

If I understand it correctly, commands are same only checking of firmware has to allow 6.x. Am I right?

Comment 3 Hans Middelhoek 2015-09-02 16:54:44 UTC

@Marek
You're right. Commands are the same for firmware 5 and 6 but firmware 6 can't be detected by fence_apc.
