My question is tho, since I can boot into either OpenSolaris or Solaris (but not both at the same time obviousvly :) i'd like to be able to mount the other disks into whatever host OS i boot into.
Is this possible& recommended?
Definitely possible. Where do you keep your user data? It isn't clear that there is much utility in cross mounting rpools from Solaris/sxce to Open Solaris; better to keep your user data in one or more separate data pools and to just mount them. That simplifies backups, too.
Is there any scope for inconsistency if say i upgrade OpenSolaris with new ZFS versions but continue mounting a mirror in Solaris with old versions?
You have to watch out for the gratuitous update-archive problem http://defect.opensolaris.org/bz/show_bug.cgi?id=11358 at reboot. Otherwise AFAIK you just have to be careful. So far ZFS seems to have kept backwards compatibility. Just don't accidentally do a zpool upgrade :-). Because of 11358, I would not recommend cross mounting the rpools. But it isn't clear that that is what you really want to achieve...
Many thanks, cam
