Description Marek Grac 2009-01-26 12:55:55 UTC

+++ This bug was initially created as a clone of Bug #472781 +++

Description of problem:

/sbin/fence_lpar doesn't properly report power status when an lpar is in Open Firmware.

Version-Release number of selected component (if applicable):
cman-2.99.12-1.fc10.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Boot a system into open firmware
2. Run fence_lpar poweroff or reboot ... it thinks it's already powered off.

The following change to /sbin/fence_lpar fixes the problem...

    ## Transformation to standard ON/OFF status if possible
    if status in ["Running", "Open Firmware"]:
        status = "on"
    else:
        status = "off"

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

More information and reason for this action is here:

Update, in order for reboot operations to work properly ...

Without this fix.  I can 

1) Power off
2) It sees the state "Shutting Down" and thinks that means it's off.
3) I then run power on ... and it fails since the machine is still in "Shutting Down" state.

FYI this issue is now fixed in rawhide. Updates to F10 and F9 will come soon.
