V class not booting from alt path

[Bernhard Mueller · Accepted solution]

I'd suggest using rmboot on the alternate boot disk and then redo the all the mkboot steps, just to give it a try. In what you did I cannot find an error, which would imply to use lvreduce, vgreduce, and then restart from scratch with at pvcreate -f -B ....

If you retry, I would omit the ODE stuff (updatediaglif2), to make sure that's not screwing up something, actually you do not need it to have a bootable mirror disk.

Thanks Bernhard!!

I did the rmboot and redid the mkboot commands and was able to bo alt ipl!! Should one always use rmboot before mkboot commands when mirroring a disk?

Thanks again everybody!

Hi,

regarding your latest question, I have mirrored quite a few boot disks and so far I have never had to use rmboot....

However, whatever you want to do with "used" equipment, it is always a good idea to cleanup the arena as far as possible.
