I/O erroer when pvcreate
In my D calss server I want to make new vg. Initially pv create and Mknod comman worked well, but next VGcreate command did not go through. the msg is "vgcreate: Couldn't open physical volume "/dev/dsk/c0t8d0":
I/O error.
in my first command MEDIAINIT I got msg I/O error too. Ioscan command shows HD claimed.

Re: I/O erroer when pvcreate
# dd if=/dev/rdsk/c0t8d0 of=/dev/null bs=1024k
This will test your disk.
# diskinfo /dev/rdsk/c0t8d0
This is another way to verify the viability of your disk.

Re: I/O erroer when pvcreate
I think the disk is gone bad..as you can see the diskinfo command is not able to see the size of the disk. I would recommend you to have it replaced.
Best Regards,
