The EFI (Extensible Firmware Interface) file system is new
type of file system. It provides support for operating system loaders
on Itanium-based systems. The HP-UX OS loader is located on the
EFI file system.
An EFI partition of an IPF bootdisk uses the EFI file
system to store the HP-UX OS loader and is required for booting
an Itanium-based system.The EFI file system commands allow a
user to create, display and access the EFI file system on a given
device.
There are seven commands for accessing the EFI file system.
They are:
- idisk
creates operating system partitions on a disk that
will be used for IPF.
- efi_fsinit
creates new EFI file system on a specified partition.
- efi_mkdir
creates new directory on a specified EFI file system.
- efi_cp
copies a file between any supported HP-UX file system and
a specified EFI file system.
- efi_ls
lists contents of a specified EFI file system.
- efi_rm
removes an existing file from a specified EFI file system.
- efi_rmdir
removes an existing directory from a specified EFI
file system.
EFI File System Compatibility |

EFI file system commands are available for both IPF and
PA systems.
Change the time (using the time command) only in HP-UX, not in the EFI shell. Currently,
changing the time in the EFI shell causes problems with time in
HP-UX. As long as the time in HP-UX is correct, the time should
be consistent. The side effect of this problem is that the time shown
in the EFI shell (using the time command) may not represent the correct time.
