Cannot detect disk

Hi ,

OS : HP-UX Itanium (11.31)

Netapp : 7.3.6

We're facing the problem with netapp disk

Unix machine can detect LUN ID and can read disk without problem but ... I cannot activate the volume group .Please see the error below. There is something wrong with disk that Unix cannot detect them . Can you please help us out ?

Thanks in advance för any advice

[root@stodb25 /tmp/HP]
