I have a lpar installed with ubuntu 15.04. To start IO tests we begin with IO
setup, this setup tool basically creates and mounts file systems which will be
used for IO tests. If lpar is rebooted after IO setup, lpar falls into recovery
mode, so to make lpar up i should remove entry of newly created filesystems
from /etc/fstab. And i am facing this issue with multipath disks. Multipath
disks will be in undefined state, when lpar is in recovery mode.
After reboot:

I did a dump restart yesterday when lpar was coming up, logs showed
kernal panic traces. I will be attaching the log.
