There are several ways to do it, but one simple way is:

$ mount/fore $1$DGA11:
$ back/imag dsa0: $1$dga11:

It would of course be better to do it with "mini-VMS". The resulting backup would then be fully consistent. This way there might be lots of open files, which aren't backed up consistently.

Well that is hard to do in a cluster unless it is dismount from all but
one node

When the backup has finished, you dismount the disk $1$dga11: and remount it e.g.

$ mount/clus $1$dga11: common
well, yes, but I also obviously need dismount the originsl disk from the
cluster, and modify the startup mount commands.

Now you can access the disk from the mounting node and the other cluster nodes too. If it is possible - technically seen - you could also mount the disk directly from the other cluster nodes, too. (provided that the other nodes have direct access to the disk also via the SAN).
Otherwise the other nodes access the disk via the MSCP server.

Currently have an ODS-2 file system

$1$DGA7: (HAFNER) ShadowSetMember 0 (member of DSA0:)
$1$DGA8: (HAFNER) ShadowSetMember 0 (member of DSA0:)

This is in on HSG80 and was migrated from a BA356 that had host-based
shadowing
as it does here.

Now I have a new device which is a striped mirror set(raid0+1)
$1$DGA11: (HAFNER) Online

Which I want to be an ODS-5 and to replace DSA0, what steps must i go
through?

Backup DSA0 to $1$DGA11. Then

$ SET VOLUME/STRUCTURE_LEVEL=5 $1$DGA11:
Don't I need to INIT first? What about mounting?
