EFI and LFI

Hi Admins,

EFI is an interface between HP-UX and platform firmware.

Please tell me what is difference between EFI and LIF.
As i know LIF comes under BDRA so we are using s2 while listing contents of lif.

But in both the above output of efi and lif i can found HPUX and auto file.

Pavan

Hi,

EFI: Extensible Firmware Interface is the firmware interface for HP Integrity systems.

LIF: Logical Interchange Format is the directory format that contains the information that is needed to boot HP 9000 systems.

Re: EFI and LFI

For RISC systems the HPUX loader in side LIF is used, for Integrites the hpux.efi loader from EFI. Integrities only use the LABEL file from LIF, all others are there for compatibility reasons (same OS - more or less - for both, RISC and Itanium).

Hope this helps!
Regards
Torsten.

Hi,

You will not see an s2 for PARISC servers and it is PARISC servers that have a LIF area. The s2, you see on the device file is a standard slice or section of an integrity boot disk and you will not be able to see an s2 typically on a PA-RISC server. As the other partitions use different file systems, normal unix commands wil not work on HPSP and the system partition.

Please tell me what is difference between EFI and LIF.

==> EFI partition is a FAT filesytem area which is used in Intel platform. This is accessible from EFI shell.

LIF = This is avaialble in PArisc systems and the content are used to boot a PARISC system.

Even the LIF area available in S2 partition in Integrity systems, the boot loaders are used from EFIpartition\EFI\HPUX\ direcotry.
including AUTO and hpux utility.

only LABEL file is used from LIF area.
