1) Setup the disk partitions
Create a partition description file
# vi /tmp/partitionfile
2
EFI 100MB
HPUX 100%
Use idisk command to partition the disk according to this file
# idisk -wf /tmp/partitionfile /dev/rdsk/c3t1d0
idisk version: 1.2
********************** WARNING ***********************
If you continue you may destroy all data on this disk.
Do you wish to continue(yes/no)? yes
...
2) Create the new device files for the new partitions (c3t1d0s1 and c3t1d0s2)
# insf -e –Cdisk
3) Use mkboot to format the EFI partition (s1) and populate it with the EFI files below
/usr/lib/efi/ and to format the LIF volume (s2) and populate it with the LIF
files (ISL, AUTO, HPUX, LABEL) below /usr/lib/uxbootlf
# mkboot -e -l /dev/rdsk/c3t1d0 (e:EFI l:LIF)
# efi_ls -d /dev/rdsk/c3t1d0s1 (to check EFI)
File Name Last Modified Size
EFI/ 5/19/2003 0
STARTUP.NSH 5/19/2003 336
total space 103215616 bytes, free space 100076032 bytes
# lifls -l /dev/rdsk/c3t1d0s2 (to check LIF)
4) Write content of AUTO file to EFI partition:
# mkboot -a \"boot vmunix\" /dev/rdsk/c3t1d0
# efi_cp -d /dev/rdsk/c3t1d0s1 -u /EFI/HPUX/AUTO /tmp/x; cat /tmp/x
(to check it)
NOTE: Specify -a “boot vmunix -lq” if prefer that your system boots up without interruption
in case of a disk failure.
5) Initialize the LVM partition (s2) and add it to vg00
# pvcreate [-f] –B /dev/rdsk/c3t1d0s2
# vgextend vg00 /dev/dsk/c3t1d0s2
Mirror the LVs to the s2 partition
# for i in lvol1 lvol ... lvol8
>; do lvextend -m 1 /dev/vg00/$i /dev/dsk/c3t1d0s2
>; done
Write content of LABEL file, i.e. set root, boot, swap and dump device:
# lvlnboot -r /dev/vg00/lvol3
# lvlnboot -b /dev/vg00/lvol1
# lvlnboot -s /dev/vg00/lvol2
# lvlnboot -d /dev/vg00/lvol2
# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c3t2d0s2 (0/1/1/1.2.0) -- Boot Disk

# mkboot -a \"boot vmunix\" /dev/rdsk/c3t1d0 # efi_cp -d /dev/rdsk/c3t1d0s1 -u /EFI/HPUX/AUTO /tmp/x; cat /tmp/x (to check it)
