If you want a single 180GB volume, you will have to use the volume
management facilities in your operating system to combine the two
drives.  AFS can't combine volumes/partitions to produce a larger
volume.  Assuming you are using Linux, first use LVM2 to create a volume
group on the second drive with one logical volume in it and format it as
Ext3.  You can then mount it as /vicepb and move volumes from /vicepa.
Once vicepa is empty, you can unmount it and add it to the volume group.
Finally, you can extend the existing logical volume and filesystem to
use all 180GB.  Solaris/ZFS and *BSD/Vinum can do similar volume
management underneath OpenAFS.
