I think that is it, we have no clue where SLES12 puts the info about
LUNS so don't know what to change where. Found some steps for cloning
SLES11 that would most likely work if we were SLES11.

Hi
What do you mean it still mounts a gold LUN? You boot from from a NEW Lun
but root filesystem ends up beeing mounted from GOLD Lun?
First of I all I would make sure that GOLD lun after clonning is not
accesible in virtual machine anymore. Just to make it simple.
I can't remember how it is done in SLES but in RHEL there is a bunch of
stuff that refers to a specific LUN with a specific scsi_id
For example multipath (/etc/multipath.conf) configuration. In there you
usually you bond scsi_id (wwid) of Lun with friendly name (mpathX for
example).
That multipath configuration is also saved in initrd. So if you boot from
clone, it will end up mounting wrong volume.
Are you using LVM?

All,
We're doing SLES 12 on 100% LUN, with gold copy on a single 60GB LUN.
This is a new cloning approach for us so we're not sure how to make this
work. Our Linux SA got the storage admin to replicate the LUN, but when
we change the server to boot the copy, it still mounts the gold LUN.
99% sure we got the LOADDEV parms right. Does anyone have steps to
clone a LUN-only SLES 12 system?
