'devfsadm' on Sol8 will work too. In Sol8,
drvconfig/devlinks/disks/tapes commands are symlinks to devfsadm. 

% ls -li /usr/sbin | grep 68968

I've found that 'devfsadm -c disks' doesn't always rediscover
changed/added fibre channel disks, whereas 'devfsadm' without parms does.

You can, I believe, "stop" a disk in Solaris with the Solstice Disksuite
"metatool" ... might be CLI-possible too but I don't know for sure.
