Sun Volume management

Thanks to all who helped me get my Sun Blade system on line.
I just purchased a Sun Blade 100 with a 80gig HD running Solaris
v10.00. I have connected my Sun scsi 12 disk "Store edge 711 disk array"
onto the sun Blade 100.  When I go in to SMC to configure the
array I can find the scsi drives on the blade system. and the 2 tape 
drives on the end of the scsi
chain. All is OK.

At this point I need to configure a raid 0 and 1 on my 12 drives in 
the(storedge 711multipack) . Can any one tell me the best free software 
to use, where to get it and how to install it to complete this raid 
configuration.
