We installed the Mirror software successfully, and then try to configure the boot mirror.
Here is the sequence we used:
pvcreate -f -B /dev/rdsk/cxtydz: OK
mkboot -l /dev/rdsk/cxtydz: OK
mkboot -a "hpux -lq ($HW_PATH;0)/stand/vmunix" dev/rdsk/cxtydz: OK
vgextend vg00 /dev/dsk/cxtydz : KO with following error message:
vgextend: Warning: Max_PE_per_PV for the volume group (4328) too small for this
PV (4375).
Using only 4328 PEs from this physical volume.
vgextend: Couldn't install the physical volume "/dev/dsk/c2t1d0".
Unable to read the physical volume.
Other information:
#ioscan
0/1/1/0.0.0 disk HP 73.4GST373454LC
0/1/1/0.1.0 disk HP 73.4GMAS3735NC
# dd if=/dev/dsk/c2t1d0 of=/dev/null bs=1024k
70007+1 records in
70007+1 records out
Hard disks aren't the same model, could be the raison of this problem ?

Re: Vgextend failed
==>HP UX 11.23 running on **Itanium** with 2 Hd, the second Hd wasn't used. Due to a crash disk, the main disk has been replaced.
We installed the Mirror software successfully, and then try to configure the boot mirror.
Here is the sequence we used:
==>1st up all, Mirroring in Itanium servers has different procudure, its not same like PA-RISC.
Confirm what is the model of your system, #uname -a
==>2nd check and verify the disk to mirror.
#ioscan -fnC disk
#diskinfo /dev/rdsk/cxtydz
#dd if=/dev/rdsk/cxtydz of=/dev/null bs=1024 count=50
Check through SAM as well,
#sam > Go to Disks and File system>
==>Pls provide the following outputs,
#ioscan -fnC disk
#diskinfo /dev/rdsk/cxtydz
#dd if=/dev/rdsk/cxtydz of=/dev/null bs=1024 count=50
#strings /etc/lvmtab
#vgdisplay -v vg00

Solutionthe problem is about the Max PE per PV setting of the volume group.
The first disk that you added when creating the volume group is smaller than the disk that you're trying to add now.
First disk: number of PEs ---> 4328
Disk adding now: number of PEs ---> 4375
To change this setting you have to use vgmodify with -e option, see man vgmodify and the following link:
http://docs.hp.com/en/5992-4589/ch03s04.html
The link refers to HP-UX 11.31 but the concept is exactly the same.
HTH.
Best regards,
Fabio

Re: Vgextend failed
How do you mirror vg00 on Itanium systems that are running B.11.23?
RESOLUTION
NOTE: There are differences in procedure between 11.22 and 11.23.
Please refer to KBRC00011156 for B.11.22.
1. From HPUX, use vgdisplay to identify the disk that is in vg00. Use
ioscan to find the spare disk.
# vgdisplay -v --> vg00 is on /dev/dsk/c2t1d0s2 in this example
# ioscan -efunC disk --> Let's assume c3t2d0 for this example
2. Create the system, OS, and service partitions.
# cat > /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB
# idisk -wf /tmp/partitionfile /dev/rdsk/c3t2d0
idisk version: 1.31
********************** WARNING ***********************
If you continue you may destroy all data on this disk.
Do you wish to continue(yes/no)? yes <-- Answer "yes" and not "y"
3. Create device files needed for the new partitions.
# insf -eC disk
4. Verify the partition table.
# idisk /dev/rdsk/c3t2d0
5. Verify that the device files were created properly.
# ioscan -efnC disk --> c3t2d0 is 0/1/1/1.2.0
6. Initialize the efi partition for use.
# efi_fsinit -d /dev/rdsk/c3t2d0s1
7. Populate the /efi/hpux/ directory in the new EFI system partition.
# mkboot -e -l /dev/rdsk/c3t2d0
8. Change the auto file for the mirror to boot without quorum.
NOTE: Using "s1"
# echo "boot vmunix -lq" > /tmp/AUTO.lq
# efi_cp -d /dev/rdsk/c3t2d0s1 /tmp/AUTO.lq /EFI/HPUX/AUTO
NOTE: We assume that if we boot from the primary, the mirror is fully
functional and therefore we don't need to override quorum. Your site
might require that both disks override quorum.
9. Verify the contents of the auto file on the primary and the mirror.
NOTE: Using "s1"
# efi_cp -d /dev/rdsk/c2t1d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri
# efi_cp -d /dev/rdsk/c3t2d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.alt
# cat /tmp/AUTO.pri
# cat /tmp/AUTO.alt
10. Add the new partition to vg00.
NOTE: Using "s2"
# pvcreate -fB /dev/rdsk/c3t2d0s2
# vgextend vg00 /dev/dsk/c3t2d0s2
11. Mirror all logical volumes in vg00.
NOTE: Using "s2"
# lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c3t2d0s2
.
.
.
# lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/c3t2d0s2
12. Add the new disk to /stand/bootconf.
NOTE: Using "s2"
# echo "l /dev/dsk/c3t2d0s2" >> /stand/bootconf
13. Verify that the new disk was added to vg00, and the lv's are in sync.
# vgdisplay -v vg00
14. Verify that the BDRA was updated properly. Take note of the HW paths for
step 15.
# lvlnboot -v
15. Add EFI primary and high availability boot path menu entries.
# setboot -p 0/1/1/0.1.0 <-- Set primary disk
# setboot -h 0/1/1/1.2.0 <-- Set mirror disk
# setboot -b on <-- Set autoboot on
16. Verify that the primary and mirror boot paths are configured properly.
# setboot
17. Test the new mirror by booting off of it.
# shutdown -r -y 0
18. Select "HP-UX HA Alternate Boot" to test the mirror.
EFI Boot Manager ver 1.10 [14.61] Firmware ver 2.21 [4334]
Please select a boot option
HP-UX Primary Boot: 0/1/1/0.1.0
HP-UX HA Alternate Boot: 0/1/1/1.2.0
EFI Shell [Built-in]
20. Verify which disk/kernel you booted from.
# grep "Boot device" /var/adm/syslog/syslog.log
vmunix: Boot device's HP-UX HW path is: 0.1.1.1.2.0
21. Remove temporary files.
# rm /tmp/partitionfile /tmp/AUTO*
Done.

Re: Vgextend failed
Here is the procedure for Itanium servers,
Mirroring in Itanium servers
==============================
1) Create partition file
#cat /tmp/partitionfile
>3
>EFI 500MB
>HPUX 100%
>HPSP 400MB
>EOF
2) Create EFI partitions
In this eg. /dev/rdsk/c3t2d0 is disk, you may replace with your disk.
#idisk -wf /tmp/partitionfile dev/rdsk/c3t2d0
3) Create device files needed for the new partitions.
#insf -eC disk
4) Verify with idisk and ioscan command.
#idisk dev/rdsk/c3t2d0
#ioscan -efnC disk
5) Initialize the efi partition for use,
# efi_fsinit -d dev/rdsk/c3t2d0s1
6) Populate the /efi/hpux/ directory in the new EFI system partition.
# mkboot -e -l dev/rdsk/c3t2d0
7) Change the auto file for the mirror to boot without quorum.
NOTE: Using "s1"
# echo "boot vmunix -lq" > /tmp/AUTO.lq
# efi_cp -d /dev/rdsk/c3t2d0s1 /tmp/AUTO.lq /EFI/HPUX/AUTO
NOTE: We assume that if we boot from the primary, the mirror is fully
functional and therefore we don't need to override quorum. Your site
might require that both disks override quorum.
8) Verify the contents of the auto file on the primary and the mirror.
NOTE: Using "s1"
# efi_cp -d /dev/rdsk/c2t1d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri
# efi_cp -d /dev/rdsk/c3t2d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.alt
# cat /tmp/AUTO.pri
# cat /tmp/AUTO.alt
9) Create PV,
NOTE: Using "s2"
#pvcreate -fB /dev/rdsk/c3t2d0s2
10) Extend vg00
#vgextend vg00 /dev/dsk/c3t2d0s2
11) 11. Mirror all logical volumes in vg00.
NOTE: Using "s2"
# lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol5 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol6 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol7 /dev/dsk/c3t2d0s2
# lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/c3t2d0s2
12) Add the new disk to /stand/bootconf.
NOTE: Using "s2"
# echo "l /dev/dsk/c3t2d0s2" >> /stand/bootconf
13) Verify that the new disk was added to vg00, and the lv's are in sync.
#vgdisplay -v vg00
14) Verify that the BDRA was updated properly.
#lvlnboot -v
15) Update NVRAM for the alternate/high availability boot disk and verify,
#setboot -h
#setboot
16) Test the new mirror by booting from that.
# shutdown -r -y 0
17) Select "HP-UX HA Alternate Boot" to test the mirror.
EFI Boot Manager ver 1.10 [14.61] Firmware ver 2.21 [4334]
Please select a boot option
HP-UX Primary Boot: 0/1/1/0.1.0
HP-UX HA Alternate Boot: 0/1/1/1.2.0
EFI Shell [Built-in]
18) Verify which disk/kernel you booted from.
#grep "Boot device" /var/adm/syslog/syslog.log
vmunix: Boot device's HP-UX HW path is: 0.1.1.1.2.0
or
#dmesg|grep -i boot
Boot device's HP-UX HW path is: 0/1/1/1.2.0
19) Remove temporary files.
# rm /tmp/partitionfile /tmp/AUTO*

Re: Vgextend failed
Points 1 to 7 : OK
Point 8: content of /tmp/AUTO.pri: boot vmunix, content of /tmp/AUTO.alt : boot vmunix -lq
Is it serious ?
