Matthew, I don't know how to do that quickly given the current code. When you change the HD node of the device path, the whole thing changes.
The consistent name is designed to accommodate adding or removing devices and not l losing the names of the other devices in the system. This is not really designed to handle moving all the devices at one time. I have a vague memory that we use the sortlib to sort the device paths. Maybe the compare device path function should be optimized to do more detailed analysis of the actual nodes? I wonder if we use alphabetical sorting, but that should catch the numbers and sort the same in both your cases... -Jaben Sent from my iPad. > On Mar 1, 2016, at 8:11 AM, Laszlo Ersek <[email protected]> wrote: > >> On 03/01/16 16:55, Foster, Matthew I wrote: >> Is there an easy to way to force the shell to map certain partitions to FS0: >> and FS1: respectively?
