/home is a special directory that typically used for auto mount user directories that reside on a NFS server. If you want to take advantage of this convention, try these instructions. If not, you have two ways to disable automount and make /home a regular directory:
Method One:
cd / umount /home svcadm disable svc:/system/filesystem/autofs:default
Method Two:
cd /
Edit /etc/auto_home and comment out the following line:
+/home
Edit /etc/auto_master and comment out the following line:
/home
un-mount /home
umount /home
Special thanks to Laura V. and Tom W. for tips on how to accomplish this.
