HP-UX : How to create an EFI Partition on a Disk

NOTE: The DSF path and HW path. For example: 0/0/2/0.0x0.0x0 maps to /dev/rdisk/disk1
Create the system, operating system, and service partitions.

# cat /tmp/partitionfile
> 3
> EFI 500MB
> HPUX 100%
> HPSP 400MB
> EOF

# idisk -wf /tmp/partitionfile /dev/rdisk/disk1
idisk version: 1.31
********************** WARNING ***********************
If you continue you may destroy all data on this disk.
Do you wish to continue(yes/no)? yes

Create the new partition device files:

# insf -eC disk


Verify that the device files were created:

# ioscan -m lun


Initialize the EFI partition:

#efi_fsinit -d /dev/rdisk/disk1_p1


Populate the /EFI/HPUX/ directory on the new disk and verify the boot files:

# mkboot -e -l /dev/rdisk/disk1
# efi_cp -d /dev/rdisk/disk1_p1 /usr/newconfig/sbin/crashdump.efi /EFI/HPUX
# efi_cp -d /dev/rdisk/disk1_p1 /usr/newconfig/sbin/vparconfig.efi /EFI/HPUX
# efi_ls -d /dev/rdisk/disk1_p1 /EFI/HPUX
