It's possible ? Install LVM on Sun Solaris 10 ?
solaris HAS lvm installed... slvm (solaris logical volume manager). and solaris has zfs...
Sorry, but google don't find nothing about SLVM 
You can give link please ?
why do you need slvm? mirror root disk? building volumes for data? maybe you want to use zfs?
always good for solaris docs:
slvm: Solaris Volume Manager Administration Guide
zfs: Solaris ZFS Administration Guide
