[SunHELP] strange boot issue

Just noticed that it is just slice 6 on the same disk as the root, so my
earlier comments were a bit wide of the mark I think.

Did you check that /dev/dsk and /dev/rdsk are all pointing to the same disk
and it is the same as partition 0?

Can only think it is either an issue with the /etc/vfstab or in /dev or
/devices trees.

drive is ref'd separately. From memory delete the /dev/dsk and rdsk ref to the
drive you are having issues with and run devfsadm. There is probably a switch
to do this without having to do the delete the delete, just forget what it is
for now (see man page).......
