Can not install hp-ux11.23 OS on internal HDD

[supen]

Hi,
I am working on a hp rp7440 server with two cell boards and on the cell board-0 two 146 GB hard drives are connected. I have installed HP-UX11.23 on the first drive(/dev/dsk/c0t6d0)successfully and then tried to extend the vg00 with the second hard drive(/dev/dsk/c3t6d0) but getting error.
I have tried to install hp-ux11.23 directly on the second disk (/dev/dsk/c3t6d0) but it is also failed with the error message as attached.pvcreate -v /dev/rdsk/c3t6d0 is passed fine but then not able to extend the vg00 with the PV /dev/dsk/c3t6d0 not able to create a new vg with /dev/dsk/c3t6d0.

Can anybody suggest what might be the issue.

Thanks in advance

sounds like the disk may be faulty, try doing a dd from/to it and see what happens

I second Melvyn's opinion. Run

dd if=/dev/dsk/c3t6d0 of=/dev/null bs=8192

and let it run its course. For 146 GB drive, it will take a loooong time. Let it go thru, checking the output every few minutes. More than likely, you will see a read error at some point, indicating the recordable media is damaged/bad. At that point you can ctrl-c out of the running command and call your h/w support to get it replaced.

That's why you use a larger block size:
dd if=/dev/dsk/c3t6d0 of=/dev/null bs=4096k

Hi,

It might be disk c3t6d0 faulty, try to use dd command on disk c3t6d0 then check it again.

Actually th problem was with the controller back plane. It has been replace with a good one and now OS is installed.
Thanks every body for their supports.
