Not able to import a shared DG

[shashi kanth]

I have one shared DG in a 3-node VCS cluster in HP-UX11i v2.

I am not able to import the VG.

# vxdg -s import ocr_vote
VxVM vxdg ERROR V-5-1-587 Disk group ocr_vote: import failed: No valid disk found containing disk group

# vxdisk -o alldgs list | grep -i ocr_vote
EVA30000_6 auto:cdsdisk - (ocr_vote) online


# vxdisk clearimport EVA30000_6
VxVM vxdisk ERROR V-5-1-531 Device EVA30000_6: clearimport failed:
Disk write failure


Any help pleases ?
