dsfmgr -e /dev/dsk/disk14 /dev/dsk/disk0
dsfmgr -e /dev/dsk/disk6 /dev/dsk/disk1
:

See #man dsfmgr

Sometimes -e is handy, but not needed here.

oops, you do need -e, or change the order otherwise you run into conflict for disk0

dsfmgr -e /dev/dsk/disk6 /dev/dsk/disk1
dsfmgr -e /dev/dsk/disk7 /dev/dsk/disk2
dsfmgr -e /dev/dsk/disk9 /dev/dsk/disk3
dsfmgr -e /dev/dsk/disk0 /dev/dsk/disk4
dsfmgr -e /dev/dsk/disk14 /dev/dsk/disk0

DO NOT FORGET that you also have to change links in /etc/fdmns (if using advfs) or edit /etc/fstab if using UFS.

This could be possible as methioned above, you can use dsfmgr -m to "move" one device name to another, and dsfmgr -e to "exchange" between two.

But i'm wondering why are you doing that? You should start to use to see unsorted output in the results of commands. (The sort command could be handy)

Argh... i got my options mixed up.
The command I intended to show was -m,
and the -e is sometimes handy.

Oh well.
