一、知识准备
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用的/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
二、实验目的
对一台HP rx8640机器的2号分区根盘(146GB)镜像；
三、操作过程
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/c0t6d0s2 vg00卷组中只有一个盘分区c0t6d0s2
# ioscan -efunC disk --> c2t6d0 可以看到另一个磁盘和光驱

2. Create the system, OS, and service partitions.
# vi /tmp/partitionfile 建一个临时文件输入以下内容，名字随便
3 分3个区
EFI 500MB 最上面讲到了11.23的默认大小
HPUX 100% 剩余所有空间
HPSP 400MB 应该是预留替换坏扇区的空间吧！
# idisk -wf /tmp/partitionfile /dev/rdsk/c2t6d0 -w写（默认只读）-f来自于文件
idisk version: 1.31
********************** WARNING ***********************
If you continue you may destroy all data on this disk.
Do you wish to continue(yes/no)? yes
3. Create device files needed for the new partitions.
# insf -eC disk 创建磁盘分区表文件（重启自动创建）

4. Verify the partition table.

5. Verify that the device files were created properly.
# ioscan -efnC disk --> c2t6d0 is 0/0/0/3/0.6.0
6. Populate the /efi/hpux/ directory in the new EFI system partition.
# mkboot -e -l /dev/rdsk/c2t6d0
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/c0t6d0s1 /tmp/AUTO.lq /EFI/HPUX/AUTO -->原作者漏写了
# efi_cp -d /dev/rdsk/c2t6d0s1 /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/c0t6d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri
# efi_cp -d /dev/rdsk/c2t6d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.alt
# cat /tmp/AUTO.pri
boot vmunix -lq -------------------->修改后
# cat /tmp/AUTO.alt
boot vmunix -lq
9. Add the new partition to vg00.
