Solaris 10: drive type unknow ASL/APM installed

I have the ASL/APM installed for Storage Foundation 4.1 HA Standard and yet I am still getting 'drive type unknown' in my format command. vxdmpadm lists 2 available paths (as expected):

vxdmpadm getdmpnode enclosure=AMS_WMS0

Specify disk (enter its number): ^D


Any ideas? Is this a red herring perhaps?
