UEFI altered in a Boot from SAN scenario

[noldi]

I've tried to setup a BFS setup where I enter different boot paths to the OS disk behind an EVA.

The OS disk is replicated and I can alternatively boot 2 servers from this disk.

HP-UX Alternate Boot:                                 Device Path :
0/0/0/9/0/0/0/5/0/0/0.0x5001438011394d5d.0x400100000  PcieRoot(0x30304352)/
PPS EVA2, Con2, FabA                                 
PPS EVA2, Con2, FabB

When I boot HP-UX from one of the EVA OS-disk paths and I reboot the system, it will add some HP-UX boot paths (Alternate boot, etc.) to the UEFI boot menu.

This is not useful, since I already have some possible boot paths defined already and I don't want the UEFI boot menu to be altered (because of documentation purposes).

Any idea how to prevent HP-UX from altering the UEFI boot entries on the system?

Thanks & regards,

Arnold
