Mount and vfstab

Question

New to Solaris, be gentle.
I have installed, sliced and built a FS on a new SCSI drive, I then mount this to an empty directory on root using:
mount -F ufs -o logging /dev/dsk/c1t2d0s1 /DirName
All is well, until I reboot and I have to remount this again as it did not 'stick' after the reboot. I can modify the the vfstab file and this seems to have done the trick.
My question is, isn't there a way to use the mount command to make mount points 'stick' after a reboot? Shouldn't my using the mount command place an entry in the vfstab file? Am I missing something or am I going to have to open the vfstab file and modify it everytime I want a new mount to 'stick'?
thanks in advance

As mentioned, yes, you need to edit the vfstab for every new UFS file system. You can make you life a little easier with 'mount -p' which will print out all you existing mounts in a vfstab friendly format:
# mount -p
/dev/dsk/c0t0d0s0 - / ufs - no rw,intr,largefiles,logging,xattr,onerror=panic,suid
/proc - /proc proc - no
mnttab - /etc/mnttab mntfs - no
fd - /dev/fd fd - no rw,suid
/dev/dsk/c0t0d0s5 - /var ufs - no rw,intr,largefiles,logging,xattr,onerror=panic,suid
swap - /var/run tmpfs - no xattr
swap - /tmp tmpfs - no xattr,size=512m
/dev/md/dsk/d2 - /opt ufs - no rw,intr,largefiles,logging,xattr,onerror=panic,suid
Do not just copy the entire output into your vfstab, or redirect the output into your vfstab. Copy only the line pertaining to your new file system. You could maybe do something like:
# cp /etc/vfstab /etc/vfstab.20090510
# mount -p | grep [my new file system] >> /etc/vfstab
# vi /etc/vfstabAnd confirm it looks Ok. Notice the double ">". Very important! E.g., You've created a new file system on c2t0d0s0:
# cp /etc/vfstab /etc/vfstab.20090510
# mount -p | grep c2t0d0s0 >> /etc/vfstab
# vi /etc/vfstabOr, use ZFS everywhere and let it do all the work.
