Force EFI to detect a LUN in a SAN

[B.Beekmans]

Hello ,
in the folowing post

http://forums11.itrc.hp.com/service/forums/questionanswer.do?admit=109447626+1219845314826+28353475&threadId=1168312

the following is stated : " By default, EFI is not "clever" enough to detect a LUN in a SAN. You can force EFI to do this " .

Can anybody tell me how to force the EFI to detect LUN's on the SAN. ( without having a OS on the internal disks )

Regards ,
Barry

I think that document is for an old version of EFI , because what I get is this :

You need to edit the boot settings.

...
EFI Variable EFIFCScanLevel. Used with Boot Order List Login. The variable EFIFCScanLevel is maintained by EFI in the system NVRAM. If the variable is not defined or set to 0, then only devices in the Boot Order List will be logged in and reported to EFI. If the variable is set to any non zero value, then all devices found on the SAN will be logged in and reported to EFI. The Driver Configuration protocol allows this variable to be created if it does not exist. If the variable does not exist, the menu will display a message asking if it should be created.

After putting the EFIFCScanLevel variable to non zero , I see my SAN disks :
