GROWFS in solaris

Hi Gurus
Im workin in solaris platform..Actually i just want to kno the procedure that is followed before growing a file system using growfs command.V are having SAP installed in our server and its in cluster..v logged into our storage and created volumes now v need to map the luns and grow the filesystem.So please provide the detailed procedure as how to do it...And also tell me whether there will be any data loss this is done.it will be helpfull if u provide me with commands as well

Thanks in advance

What is being used to build a volume out of the LUNs now, ZFS, Vertas Volume Manager, Solstice Disksuite or something else?
