I have NW 6.5 SP5 blade server booting off from SAN. SYS on its virtual
disk on the SAN. What is the best way to backup the SYS volume before I
install SP6. I can make a copy of the virtual disk that contains the SYS
volume before installing the patch. In case there is any problem with
patch, I would like to replace the virtual disk on SAN with the previous
copy. However, since I have multiple servers holding the NDS partition,
will I run into eDir problem if I need to put the SYS back to the previous

Or anyone have other suggestion for me to handle the above.
