Comment 9 for bug 1562249

I am able to SSH into the node that shows 'failed deployment' Please let me know if there is any information you need from that machine that might help.

Here us the output of block-devices from maas UI:

and output of LSBLK from the failing node

ubuntu@HpRS1:~$ lsblk

└─cciss!c0d0p5 104:5 0 6G 0 part
cciss!c0d1 104:16 0 33.9G 0 disk

In all the above .. there is an 'sda' virtual drive or something which maybe causing the c0d0 and c0d1 to not get detected.

If this is the case .. please suggest a workaround or solution.
