Maybe the better plan:

 

Get a new disk and insert in the partner blade or get a LUN from SAN.

 

Clone the OS using DRD. Patch the clone, activate the clone (reboot from clone).

 

In case something goes wrong, just boot the original disk again.


Hope this helps!
Regards
Torsten.

Consider to shutdown, pull a disk and reboot.
