Description Dan Yocum 2016-04-25 17:49:18 UTC 
Description of problem:

I would like a way to use ironic to pxeboot an overcloud system into "rescue" mode to do basic things like inspect hardware manually, create gpt partitions, create md devices, etc.

Comment 4 Dmitry Tantsur 2017-01-06 16:51:07 UTC 
This feature is actively worked on mostly by contributors outside of Red Hat. Leaving Lucas assigned just for tracking.
Comment 6 Dmitry Tantsur 2017-01-11 11:51:17 UTC 
Upstream patches: https://review.openstack.org/#/q/topic:bug/1526449. Not making it into Ocata, apparently.
Comment 7 Ramon Acedo 2017-08-10 09:45:07 UTC 
Is the spec initially tracked initially here still valid?

Comment 8 Dmitry Tantsur 2017-08-10 10:46:26 UTC 
Yep
Comment 10 Ramon Acedo 2017-11-02 16:03:48 UTC 
Hi Dmitry, does the rescue mode need TripleO integration (rescue image or other changes)? If it does, is it still reasonable to target this to OSP 13 or should we consider it now for OSP 14?
Comment 11 Dmitry Tantsur 2017-11-02 17:05:34 UTC 
Indeed, it requires updating our IPA image to support rescue. Given the bandwidth, I'd really move it to 14.
