Hi Julia and Arne,
> Did cleaning fail at any given point with these machines?
Sorry that I didn't describe it clearly. Actually, clean is alway
success in ironic log, deploying is failed. I just wonder if the
cleaning phase did something that caused disk identification problems.
And I have found the RAID config menu. In my machine, I need to prase
"Ctrl + R" when RAID interface appear in machine boot.
Thank you very much~! In RAID config menu, I found that the state of
three disk is UB(unconfig bad).
So, if I use the Ironic service to install an operating system for a
server that has three hard disks in the 'JBOD' state, is there
anything I should pay attention to or operate? If I don't do something
for this, deploying stage give me an error 'No suitable device was
found for deployment' and 'lslbk' is empty. After clean successed and
deploy faided, the disk state is "Unconfigured bad".
best wishes to you,
Han Guangyu
