cluvfy : "The following storage type is not supported: DISK"

Hello,

Installing Clusterware 10.2 on HP-UX Itanium.  I'm placing the OCR and voting disk on shared raw devices, but cluvfy errors with the following when verifying storage:

     $ runcluvfy.sh comp ssa -n <node1>,<node2> -s /dev/rdsk/ora_ocr_raw_2g,/dev/rdsk/ora_voting_raw_1g
     Verifying shared storage accessibility
     Checking shared storage accessibility...
     ERROR:  /dev/rdsk/ora_ocr_raw_2g
     The following storage type is not supported:
      "DISK"
     ERROR:  /dev/rdsk/ora_voting_raw_1g
     The following storage type is not supported:
      "DISK"
     Shared storage check failed on nodes "<node1>,<node2>".
     Verification of shared storage accessibility was unsuccessful on all the nodes.
