Hi Amit,

Did you do a pvcreate on the physical disk,

pvcreate /dev/rdsk/c16t7d7

Make sure you are able to see the disk in ioscan and can access it,

# diskinfo -v /dev/rdsk/c16t7d7
# dd if=/dev/rdsk/c16t7d7 of=/dev/null bs=1024k

hope this helps.

You need to pvcreate the disk first.

If pvcreate /dev/rdsk/c16t7d7 errors, then use the -f option if you are sure the disk isn't used elsewhere...

Hey;

As mentioned, it's the pvcreate. I've been doing UNIX admin for 14 years and HP admin for 10; and I always forget that damned thing!

pvcreate ${raw_dev}

Do a pvcreate -f

It should work
