HPUX 11.23与11.22版本配置根盘镜像的最大的不同:
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。
2. EFI分区大小从原先的100M，增加到500M。
下面是HPUX 11.23配置根盘镜像的详细步骤：
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.
# 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 <-- 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. 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.
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"
# vi /stand/bootconf
l /dev/dsk/c2t1d0s2
l /dev/dsk/c3t2d0s2
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*
