I am moving hosts from one SAN to another one. We are using UCS and boot from SAN.
So I zoned everything and installed VMware 5.5 to a new 15 GB LUN, I am booting from that new LUN. The problem is that the old boot from SAN LUN is still there (accessible from the host).
I tried to do the normal Unmount and then Detach but it fails because the device still contains a diagnostic partition (from the original boot from SAN partition).
How can I delete the old coredump partition so I can remove this old, unneeded datastore?
Thank you all,
