USB Drive for Solaris

I have a T2000 server running solaris 10, it has 4 USB ports. I want to extend the storage capacity by attaching an external USB drive and mounting it as an other mount point.
How do I do that, the following link gives information about USB in Solaris OS,

but I was wondering do I have to run newfs command on the newly discovered drive.
Can someone pls ellaborate on that please.

Thanks

if the drive is found as a new disk and you want to write on this disk, you have to give it a filesystem... this could be zfs or ufs. and in case of ufs you need newfs to build the filesystem!
so yes, if you like to use ufs, you have to run newfs.
