If you see an IO error at this point then it is likely that
you are not able to create any filesystems on that disk.

divvy: could not write new divvy table: I/O error

This could be, for example, because the disk being used
already had an operating system on it and the master boot
record (mbr) ; superblock table needs overwriting with
either a low level format or as root on the OSR6 box run
the "dd" command on to the disk2 (/dev/rhd10):

# dd if=/dev/zero of=/dev/rhd10

After 10 seconds, interrupt this by hitting the <Del> key.

With this command, we have deleted any traces of Partition
table on the first sector on the disk.

This disk will now present itself to the OS as a new
formatted disk. If you are still experiencing problems then
it is possible that the disk may be faulty.
