How to determine if i have spare disks in Solaris?

Hi Guys,
obviously new to SOLARIS SUN SPARC 5.10
I would really appreciate if you help me see how to find free disks available in my system.
Like i am a linux admin. If i want to grow a file system in linux. I would first have a look at my volume groups to see if they have free PEs if not then i will look for another disks.
Does it work same way in Solaris? Any help would be much appreciated

thanks for your answer.
I have been through the guide. The part i did not understand is how to see if i have spare disk available?

I understood the concept of slice and mirror. but did not understand how to see free disk.I am also putting some outputs. below
I am highlighting the file system to be expanded

Code:

bash-3.2# df -h
