IBM power8 hmc console disconnects at root prompt for rear rescue #1764
Comments
|
Hi @pspatola101, /dev/hvc0 is not only used by XEN. It is also the default console for POWER when using HMC virtual console (in PowerVM). How do you use your system? :
|
|
I'm using the PowerVM. |
|
Somewhere I read that I need the mingetty package on the linux lpar for the restore to work properly? |
|
@pspatola101, If you are on PowerVM, then you should stay with If you still have errors with your console, you should also give a try to the current master branch (some patches regarding dbus could help to detect the console during boot on rescue media #1743) @jsmeix , What do you think about the following message: |
|
I downloaded the latest rear and created an rpm package with it: I ran the rear rescue again and recovered the system on another lpar and it worked! Many thanks! |

Are you using legacy BIOS or UEFI boot?BIOS
Brief description of the issue: The hmc console vterm disconnects when I get to the root prompt for recovery.
sssxfs03 login: root
-bash: cannot set terminal process group (-1): Inappropriate ioctl for device
-bash: no job control in this shell
At this point I cant type anything in. I tried setting the TERM but that didnt work. I did notice during the recovery the message.
[ 0.000103] console [hvc0] enabled, bootconsole disabled
[ 0.000103] console [hvc0] enabled, bootconsole disabled
The hvc is for a XEN and not for IBM Power. Is there a way to change this?
This is the full recovery:
