Backup, yes do it. But here is how to do it:

hpacucli ctrl slot=0 ld 1 add drives=allunassigned

This should add the additional drives to your first logical drive and
expand it. Whenever I do this, I reboot now so FreeBSD sees the 
new larger physical disk.

In most cases now you have to update the partition table, either
by addition another slice or changing the size of your FreeBSD slice.

If the file system you want to grow is the last one in disklabel, you
can use disklabel to change the size of it, also the total line (c:)
needs to grow. 

And then finally you can use growfs on the file system.
