Thanks to all who replied: the solution turned out to be related to
metadbs on other disks which had not been reformatted and relabelled.

After repartitioning disk 0 on controller 1 (c1t0d0), during
installation the error message came up:

Could not reinitialize system state

mkdir "a/var/sadm/laucher" Read only filesystem

The cause turned out to be:
metadata dbs on the attached drives (c1t1d0-c1t5d0) caused a metainit
error which caused the above error
Our solution
Pull the 5 drives out during installation

There are probably other solutions but that worked.
