efi_fsinit — write an EFI file system header on a device file


efi_fsinit [-d devicefile]


efi_fsinit writes an EFI file system header on a device file.

The EFI file system is based on the FAT file system and used by the Itanium-based system BIOS to locate an HP-UX bootloader. See efi(4).

Before any other EFI commands can be run, efi_fsinit must be run to initialize the file system on a device file.


efi_fsinit recognizes the following option:

-d devicefile

Write the file system header on device devicefile. Without the -d option, efi_fsinit uses the device file specified in the environment variable EFI_PARTITION if it is defined. The -d option overrides the EFI_PARTITION environment variable.


efi_fsinit returns exit code 0 if the EFI file system is initialized successfully. Otherwise it prints a diagnostic message and returns nonzero.


Successful completion.


Error condition occurred.


Write an EFI file system header on device file /dev/rdsk/c1t4d0s1:

efi_fsinit -d /dev/rdsk/c1t4d0s1

Write an EFI file system header on the persistent device file /dev/rdisk/disk7_p1 (see intro(7)):

efi_fsinit -d /dev/rdisk/disk7_p1


efi_fsinit was developed by HP.
