Thanks to Pat OBrien, Oisin McGuinness and David Nillesen for their suggestions.
The quickest method to change LSM is to use volsave on the old server to save the LSM configuration. Delete the LSM configuration from the disk and edit /etc/sysconfigtab to remove the LSM options.
Boot the disk on the new server using genvmunix in single user mode, then edit the text files (from volsave) in /usr/var/lsm/db to reflect the new server SCSI devices, and use volrestore with the -f option to ignore the checksum error (due to the editing).
This will build the LSM using the new devices. The ASE TruCluster settings seem to ignore the physical devices and are happy that the LSM is all correct after the volrestore for their disk group.
I tried this on a copy of the disk on the new server and it seems to work, so I'll take my chances on the production systems over the weekend.
There was also a similar procedure suggested using vdump and vrestore to achieve the same results.
