HP 9000 11i v1 (11.11) / 11i v2 (11.23)
1. Identify the available disk to mirror the vg00 logical volumes.
# strings /etc/lvmtab | grep dev
/dev/vg00
/dev/dsk/c3t3d0
# ioscan -funC disk
disk 0 1/0/1/0/0/1/3.0.6 sdisk CLAIMED DEVICE HP 36.4GST336607FC
/dev/dsk/c3t6d0 /dev/rdsk/c3t6d0

/dev/dsk/c#t#d# /dev/rdsk/c#t#d#
2. Create and populate the boot disk LIF area. Be sure to use the "-B" flag to allocate space for the BDRA
# pvcreate -fB /dev/rdsk/c#t#d#
# mkboot /dev/rdsk/c#t#d#
3. Change the AUTO file on both boot disks to hpux -lq so the host can boot without quorum if one mirror disk fails.
# mkboot -a "hpux -lq" /dev/rdsk/c#t#d#
# mkboot -a "hpux -lq" /dev/rdsk/c#t#d#
4. Check the boot string in the AUTO file. This command should output: "hpux -lq"
# /usr/bin/lifcp /dev/rdsk/c#t#d#:AUTO -
5. Add the disk to vg00.
# vgextend vg00 /dev/dsk/c#t#d#
6. Mirror all vg00 logical volumes
# lvextend -m 1 /dev/vg00/lvol# /dev/dsk/c#t#d#
7. Verify that the BDRA is up to date.
# lvlnboot -R
8. Add a line to /stand/bootconf so SD-UX knows which disks are boot disks.
# vi /stand/bootconf
l /dev/dsk/c#t#d#
l /dev/dsk/c#t#d#
9. Configure the second disk as an alternate boot path in the system NVRAM.
# setboot -p #/#/#/#/#.#.#
# setboot -a #/#/#/#/#.#.#
10. Check the status of the NVRAM configuration.
# setboot
HP 9000 11i v3 (11.31) with persistent DSF
Mirroing boot disks on HP-UX 11.31 HP 9000 system can been done using
the legacy special devices files or the new persistent devices file of
the new Mass Storage Stack, also know as Agile View. This document
discuses Agile View.

2. Use pvcreate and mkboot to format and populate the disk:
# pvcreate -f -B /dev/rdisk/disk7
# mkboot -l /dev/disk/disk7
3. Change the AUTO file on both boot disks to hpux -lq so the host can boot without quorum if one mirror disk fails.
# mkboot -a "hpux -lq" /dev/rdisk/disk12
# mkboot -a "hpux -lq" /dev/rdisk/disk7
4. Add the disk to vg00. Be sure to use the "-B" flag to allocate space for the BDRA.
# vgextend /dev/vg00 /dev/disk/disk7
5. Starting with the boot, swap, and root logical volumes, run lvextend to mirror each logical volume:
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol1 /dev/disk/disk7
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol2 /dev/disk/disk7
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol3 /dev/disk/disk7
# /usr/sbin/lvextend -m 1 /dev/vg00/lvoln /dev/disk/disk7
6. Run the following lvlnboot commands to reestablish LVM’s knowledge
of the root and boot file systems and primary swap and dump.
# /usr/sbin/lvlnboot -b /dev/vg00/lvol1
# /usr/sbin/lvlnboot -r /dev/vg00/lvol3
# /usr/sbin/lvlnboot -s /dev/vg00/lvol2
# /usr/sbin/lvlnboot -d /dev/vg00/lvol2
# /usr/sbin/lvlnboot -R
7. Add the block device special file of the HP-UX (second) disk to
the file /stand/bootconf. The lower case "l" in the following command
indicates that the disk is managed by LVM or VxVM.
# /usr/bin/echo "l /dev/disk/disk7" >> /stand/bootconf
8. If desired, set the alternate boot path to the mirror_disk using the Lunpath H/W Path. Check step 1.
# /usr/sbin/setboot -a 0/1/1/1.0x0.0x0

2. Use the following commands to determine the size in megabytes of
the (1) EFI, (2) HP-UX, and (3) HPSP partitions on the current boot
disk:
# /usr/sbin/diskinfo -b /dev/rdsk/c0t6d0s1 \
| awk '{print $1 / (1024)}'
# /usr/sbin/diskinfo -b /dev/rdsk/c0t6d0s2 \
| awk '{print $1 / (1024)}'
# /usr/sbin/diskinfo -b /dev/rdsk/c0t6d0s3 \
| awk '{print $1 / (1024)}'
3. Create an IPF partition description file to create the EFI and OS
partititions using your favorite method. Theses two example shows how to
create a IPF description file with an EFI partition of 500 Megabytes
and a HPSP partiiton of 400 Megabytes.
# print '3\nEFI 500MB\nHPUX 100%\nHPSP 400MB' > /tmp/idf
4. Use idisk to setup the disk partitioning using the file created above:
# idisk -wf /tmp/idf /dev/rdsk/c#t#d#
NOTE: There will be a prompt with a message saying the operation may be destructive and asks to continue. Answer yes
for the operation to be successful. If the prompt is answered with only
the 'y' character an error will be received along with a message user aborting.
5. Use the insf command to create device files for all the newly-created partitions.
# /usr/sbin/insf -e -H
6. Use mkboot to format and populate the newly created EFI partition:
# mkboot -e -l /dev/dsk/c#t#d#
7. Change the AUTO file on both boot disks to "boot vmunix -lq" so the host can boot without quorum if one mirror disk fails.
# print 'boot vmunix -lq' > /tmp/auto
# efi_cp -d /dev/rdsk/c#t#d#s1 /tmp/auto /efi/hpux/auto # Primary disk
# efi_cp -d /dev/rdsk/c#t#d#s1 /tmp/auto /efi/hpux/auto # Alternate disk
8. Run the pvcreate command on the character device file for the
HP-UX (second) partition of the mirror disk, using the "-B" flag to make
the disk bootable, and the "-f" flag to overwrite any pre-existing data
on the disk.
# /usr/sbin/pvcreate -f -B /dev/rdsk/c#t#d#s2
9. Extend the root volume group to the HP-UX partition of the mirror
disk, using the block device file of the second EFI partition.
# /usr/sbin/vgextend /dev/vg00 /dev/dsk/c#t#d#s2
10. Starting with the boot, swap, and root logical volumes, run lvextend to mirror each logical volume on the volume group.
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c#t#d#s2
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c#t#d#s2
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c#t#d#s2
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol# /dev/dsk/c#t#d#s2
11. Run the following lvlnboot commands to establish LVM’s knowledge
of the root and boot file systems and primary swap and dump on the
alternate disks.
# /usr/sbin/lvlnboot -b /dev/vg00/lvol1
# /usr/sbin/lvlnboot -r /dev/vg00/lvol3
# /usr/sbin/lvlnboot -s /dev/vg00/lvol2
# /usr/sbin/lvlnboot -d /dev/vg00/lvol2
# /usr/sbin/lvlnboot -R
12. Add the block device special file of the HP-UX (second) partition
of the mirror to the file /stand/bootconf. The lower case "l" in the
following command indicates that the disk is managed by LVM or VxVM.
# /usr/bin/echo "l /dev/dsk/c#t#d#s2" >> /stand/bootconf
13. If desired, set the alternate boot path to the mirror_disk using the hardware path. Check step 6.
# /usr/sbin/setboot -a
# /usr/sbin/setboot -h
14. If the mirror disk includes an HPSP partition, use the efi_fsinit
command on the character device file for the HPSP (third) partition to
initialize it with an EFI file system.
# /usr/sbin/efi_fsinit -d /dev/rdsk/c#t#d#s3
Integrity 11i v3 (11.31) with persistent DSF
Mirroing boot disks on HP-UX 11i v 3 (11.31) Integrity system can
been done using the Legacy device special files or the Persistent device
special file implemented by the new Mass Storage Stack, also know as
Agile View. This document section discuses the newer method.

7. Use mkboot to format and populate the newly created EFI partition:
# mkboot -e -l /dev/disk/disk#
8. Change the AUTO file on both boot disks to hpux -lq so the host can boot without quorum if one mirror disk fails.
# print 'boot vmunix -lq' > /tmp/auto
# efi_cp -d /dev/disk/disk#_p1 /tmp/auto /EFI/HPUX/AUTO
9. Run the pvcreate command on the character device file for the
HP-UX (second) partition of the mirror disk, using the "-B" flag to make
the disk bootable, and the "-f" flag to overwrite any pre-existing data
on the disk.
# pvcreate -f -B /dev/rdisk/disk#_p2
10. Extend the root volume group to the HP-UX partition of the mirror
disk, using the block device file of the second (HPUX) partition.
# vgextend /dev/vg00 /dev/disk/disk#_p2
11. Starting with the boot, swap, and root logical volumes, run lvextend to mirror each logical volume:
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol1 /dev/disk/disk#_p2
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol2 /dev/disk/disk#_p2
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol3 /dev/disk/disk#_p2
# /usr/sbin/lvextend -m 1 /dev/vg00/lvol# /dev/disk/disk#_p2
12. Run the following lvlnboot commands to reestablish LVM’s
knowledge of the root and boot file systems and primary swap and dump.
# /usr/sbin/lvlnboot -b /dev/vg00/lvol1
# /usr/sbin/lvlnboot -r /dev/vg00/lvol3
# /usr/sbin/lvlnboot -s /dev/vg00/lvol2
# /usr/sbin/lvlnboot -d /dev/vg00/lvol2
# /usr/sbin/lvlnboot -R
13. Add the block device special file of the HP-UX (second) partition
of the mirror to the file /stand/bootconf. The lower case "l" in the
following command indicates that the disk is managed by LVM or VxVM.
# /usr/bin/echo "l /dev/disk/disk#_p2" >> /stand/bootconf
14. If desired, set the alternate boot path to the mirror_disk using the Lunpath H/W Path. Check step 1.
# /usr/sbin/setboot -a 0/0/0/0.0x1.0x0
15. If the mirror disk includes an HPSP partition, use the efi_fsinit
command on the character device file for the HPSP (third) partition to
initialize it with an EFI file system.
# /usr/sbin/efi_fsinit -d /dev/rdisk/disk18_p3
Automating LVM mirroring
The following script can be use to automate LVM bootable volume mirroring on HP-UX 11i.
#!/usr/bin/sh
#
# Script mk_mirror.sh adds $1 disk into vg00 if not already added
# and makes $1 mirror boot disk
# It comes with no support and HP makes no representations as to its
# fitness for purpose. It is up to whoever uses this program to ensure
# that whatever functionality it provides is what they require.

Troubleshooting
HP 9000
Use the following procedure to verify the current state of boot data your primary and alternate boot disks.
1. Check that alternate boot path correspond to alternate boot disk
# ioscan -fnkC disk
# setboot
2. Check LVM boot pointers.
# lvlnboot -v
3. Check that LIF area exits and is populated on the alternate boot
disk. Replace c#t#d# with the "dsf" of your alternave boot disk.
# lifls /dev/dsk/c#t#d#
4. Check the AUTO boot flag.
# lifcp /dev/dsk/c#t#d#:AUTO -
5. Check that /stand/bootconf contains both boot disks.
# cat /stand/bootconf
Integrity
Monitor volume group syncronization
If you need to monitor the advance of the volume group
sincronization, you can use this script to quickly monitor extends that
are still "stale". Running this command should give a lower value each
iteration until it reachs zero.
while true
do
for lv in $(vgdisplay -v | grep "LV Name" | awk '{print $3}')
do
lvdisplay -v $lv
done | grep -i stale | wc -l
sleep 10
done
Example:
# while true
> do
> for lv in $(vgdisplay -v vg00 | grep "LV Name" | awk '{print $3}')
> do
> lvdisplay -v $lv
> done | grep -i stale | wc -ldone | grep -i stale | wc -l
> sleep 10

Reference
so it was no more possible via GUI to change it ...
Where client is the username, server is type of service – pptpd for
our example, secret is the password, and IP addresses specifies which IP
address may authenticate.
By setting ‘*’ in IP addresses field, you specify that you would accept
username/password pair for any IP.
