adding additional drive to sco the is xenix

I am taking an old xenix drive and installing it in a recent SCO Build Server. I have gone through the process of running mkdev hd twice since the drive is a SCSI then proceed to run mkdev fs and when I attempt to add one of the shown partitions I get the following:

fsck: cannot determine filesystem type of /dev/drv4.

When I run divvy I get:

Name | Type | New FS | # | First Block | Last Block |
+-------------------+------------+--------+---+-------------+------------+
| boot | EAFS | no | 0 | 0| 15359|
| swap | NON FS | no | 1 | 15360| 209919|
| root | HTFS | no | 2 | 209920| 4442101|
| drv3 | NOT USED | no | 3 | -| -|
| drv4 | NOT USED | no | 4 | -| -|
| drv5 | NOT USED | no | 5 | -| -|
| recover | NON FS | no | 6 | 4442102| 4442111|
| hd0a | WHOLE DISK | no | 7 | 0| 4443119|

Any ideas?

Thanking you in advance.....
