Bug Description

While trying to deploy a ppc64el host on MAAS 1.9 I ended up having odd power issues. It appeared to be sending the right power commands, and would power it on and off, but never seemed to recognise that it was powered off.

I had a bit of a poke around in the code and found something interesting in provisioningserver/drivers/power/ipmi.py:

    def _issue_ipmi_power_command(command, power_change, power_address, env):
    ..... snip ....
            if 'on' in output:
                return 'on'
            elif 'off' in output:
                return 'off'
            else:
                return output

The host I was trying was called cameron, and the output from the ipmipower looked like:

  cameron.1ss.ilo: off

This mean that no matter what happened, once it was turned on it never realised it was off again.

Once I changed the ipmi hostname to the IP address, I could run a power check and it instantly realised it was off.

MAAS Version: 1.9.1+bzr4543-0ubuntu1 (trusty1)

Please let me know if you need any further information.

Hi Brad,

I believe this bug was fixed in MAAS 1.9.2, can you please upgrade to 1.9.2 ? Thanks!

This isn't a dupe of bug 1508741 and it's not fixed in 2.0; I wrote a test this morning that shows it exists; see the linked branch.

@Gavin,

The bug is dupe. This bug here that Brad reported has been fixed in 1.9.2 but not fixed in 2.0. Bug 1508741 was exactly the same issue, it is just described differently.
