A solution that worked, and suggested by a Veritas-bu subscriber, was to 
manually add the tape drives to st.conf and reload the driver.  This 
successfully generated the missing /dev/rmt entries and allowed me to proceed 
with the robot and drive configuration using tpconfig.

Steps:

Added entries to /kernel/drv/st.conf:
name="st" parent="fp" target=0 lun=0 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=1 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=2 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=3 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=4 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=0 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=1 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=2 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=3 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=4 fc-port-wwn="500308c00189780b";

Determine st driver Id and display details:
modinfo | grep st
...

modinfo -i 49
 Id Loadaddr   Size Info Rev Module Name
 49 786e0000  132e4  33   1  st (SCSI tape Driver 1.221)

Reloaded st driver:
modunload -i 49

modinfo -i 49
can't get module information: Invalid argument

devfsadm -i st

tpconfig work.

Backups now working fine to the new tape drives.

Adding the entry to st.conf followed by a boot -r did NOT fix my problem.  The 
missing /dev/rmt entries are still missing.

I've opened another issue with SUN.

The original six drvies in the L700 are still there and usable.

The new four drives in the Scalar i2000 do not exist in /dev/rmt, yet are shown 
in cfgadm.

SUN's response is that my st.conf is missing:

name="st" parent="fp" target=0;

Now to find time and get permission to boot the production server...
