[color="#990000"]HPUX 11.23与11.22版本配置根盘镜像的最大的不同:
[color="#990000"]1. 新增加了HPSP分区
11.22系统根盘只划分了两个分区EFI / HP-UX，在11.23系统中，划分了3个分区，分别为EFI / HP-UX / HPSP相应在使用idisk命令划分硬盘分区时使的 /tmp/partitionfile 文件中的内容也做了相应调整。
[color="#990000"]2. EFI分区大小从原先的100M，增加到500M。
[color="#990000"]下面是HPUX 11.23配置根盘镜像的详细步骤：
[color="#990000"]
[color="#990000"]How do you mirror vg00 on Itanium systems that are running B.11.23 ?
[color="#990000"]RESOLUTION
[color="#990000"]NOTE: There are differences in procedure between 11.22 and 11.23.
[color="#990000"]Please refer to KBRC00011156 for B.11.22.
[color="#990000"]1. From HPUX, use vgdisplay to identify the disk that is in vg00. Use ioscan to find the spare disk.
[color="#990000"]# vgdisplay -v --> vg00 is on /dev/dsk/c2t1d0s2 in this example
# ioscan -efunC disk --> Let's assume c3t2d0 for this example
[color="#990000"]2. Create the system, OS, and service partitions.
# vi /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  c3t2d0 is 0/1/1/1.2.0
[color="#990000"]6. Populate the /efi/hpux/ directory in the new EFI system partition.
# mkboot -e -l /dev/rdsk/c3t2d0
[color="#990000"]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
[color="#990000"]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.
[color="#990000"]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
[color="#990000"]10. Add the new partition to vg00.
NOTE: Using "s2"
# pvcreate -fB /dev/rdsk/c3t2d0s2
# vgextend vg00 /dev/dsk/c3t2d0s2
[color="#990000"]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
[color="#990000"]12. Add the new disk to /stand/bootconf.
NOTE: Using "s2"
# vi /stand/bootconf
l /dev/dsk/c2t1d0s2
l /dev/dsk/c3t2d0s2
[color="#990000"]13. Verify that the new disk was added to vg00, and the lv's are in sync.
# vgdisplay -v vg00
[color="#990000"]14. Verify that the BDRA was updated properly. Take note of the HW paths for
step 15.
# lvlnboot -v
[color="#990000"]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
[color="#990000"]16. Verify that the primary and mirror boot paths are configured properly.
# setboot
[color="#990000"]17. Test the new mirror by booting off of it.
# shutdown -r -y 0
[color="#990000"]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]
[color="#990000"]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
[color="#990000"]21. Remove temporary files.
# rm /tmp/partitionfile /tmp/AUTO*
