Can we increase size of SAN LUN already having data on Solaris SPARC system

Dear Team,

We have  Volume of 60 GB inside it LUN of 50GB , this is mapped to Solaris SPARC system and created mount point of /data of size 50GB

now we need to extend this mount point size already having data from 50 GB to  70GB,

so we will fist increase size of volume from 60GB to 80 GB and LUN from 50GB  to 70GB.

so on Solaris OS is this change supported, do we need to do anything special on OS level?

In short, can we extend the size of SAN mount point on Solaris OS which is already having the data?

Thanks
