Great! I also have the SUSE_REMOVE_LINUX_ROOT_PARAM=true as well. And I set the GRUB_CMDLINE_LINUX_ DEFAULT="root=/dev/disk/by-path/ccw-0.0.0101-part1 hvc_iucv=8 TERM=dumb crashkernel=103M vmhalt=LOGOFF vmpoff=LOGOFF"
101 is our boot disk. -----Original Message----- From: Linux on 390 Port <LINUX-390@VM.MARIST.EDU> On Behalf Of Aria Bamdad Sent: Thursday, October 14, 2021 6:10 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] Warning if upgrading SLES12 to SLES15 SP3 Marcy, thank you for pointing that out. I have that in my documentation since SLES12 also but when I checked, I noticed that for the server I upgraded from 12 to 15, this option was commented out! I also add SUSE_REMOVE_LINUX_ROOT_PARAM="true" but this option was still there. So it turns out that this entire thing could be avoided by the GRUB_DISABLE_LINUX_UUID=true. I point to my root device via the root= kernel option and point to the device number by-path. Thank you for reminding me to look for this option. Don't know how it got commented out or perhaps it was never uncommented.

My brain cells that contained why I did that seem to have been reused for another purpose though, so maybe it was something else. I know it had to do with clones.
