关于 逻辑卷与镜像基础知识请看 HP文档。
目的：更换一块坏磁盘，恢复1+1镜像；
信息：主盘c2t1d0s2，坏盘c2t0d0s2，新盘c2t3d0，安腾，MIRROR/UX 1.0
# uname -a
HP-UX rx6600a B.11.23 U ia64
处理三个故障：
1、从逻辑卷中删除坏卷遗留信息vgreduce，需要disk_path。
2、对新盘分区时提示操作异外idisk，提示‘User Aborting’，需要加参数q，即静默处理。
3、在设置镜像启动信息时需要写入备盘设备路径。
Tip:确定硬件设备型号与软件版本型，本设备是安腾类型，MIRROR/UX版本是1.0
Vgdiplay -v vg00时报错信息
vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c2t0d0s2":The specified path does not correspond to physical volume attached tothis volume groupvgdisplay: Warning: couldn't query all of the physical volumes.
1、一切从源头开始，vgdisplay导致的错误需要第一个解决，把坏盘的遗留信息删除。
#vgreduce -f /dev/vg00 /dev/dsk/c2t0d0s2 (c2t0d0s2为坏盘，hbh231同学没有跟disk_path,导致我执行时有误)
#rm /etc/lvmtab （删除逻辑卷data文件，可以先保存一份cp /etc/lvmtab /etc/lvmtab.old）
#vgscan -v (重新扫描当前VG)
#vgcfgbackup /dev/vg00 （保存vg00信息，此信息保存在/etc/lvmtab）
#strings /etc/lvmtab (可以查看）
2、对新磁盘分区（此partitionfile文件存在的话，就不需要创建，同时需要依据分区信息进行配置，本次分三个区。）
# vi /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB
+++++
Tip:
有的硬盘只分二个区(我没做啊，注意哦)
# vi /tmp/partitionfile
2
EFI 500MB
HPUX 100%
++++
3、对新硬盘进行分区
# idisk -qwf /tmp/partitionfile /dev/rdsk/c2t3d0 （请注意参数q）
本次中如果没有q,则出现如下报错。q参数表示静默执行
idisk version: 1.32
********************** WARNING ***********************
If you continue you may destroy all data on this disk.
Do you wish to continue(yes/no)? y
User Aborting!
4、在新分区上创建设备文件信息
#insf -eC disk
insf: Installing special files for sdisk instance 5 address 0/0/2/1.0.16.0.0
insf: Installing special files for sdisk instance 3 address 0/4/1/0.0.0.1.0
insf: Installing special files for sdisk instance 7 address 0/4/1/0.0.0.3.0
5、验证分区信息
# idisk -pa /dev/rdsk/c2t3d0
idisk version: 1.32

6、 把/efi/hpux/ 目录移支新的 EFI系统分区上.
# mkboot -e -l /dev/rdsk/c2t3d0 （正常执行是无反馈的）
++++++
因为之前把新盘加过vg00,现在需要卷组中删除物理卷，如果之前新盘没有加入vg00的请略过。
# vgreduce /dev/vg00 /dev/dsk/c2t3d0
Volume group "/dev/vg00" has been successfully reduced.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
+++++++++
7、把新盘创建为新的pv,然后把此卷加入在vg00.因为是根镜像，所以需要B参数
# pvcreate -fB /dev/rdsk/c2t3d0s2Physical volume "/dev/rdsk/c2t3d0s2" has been successfully created. # vgextend vg00 /dev/dsk/c2t3d0s2
Volume group "vg00" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
8、镜像vg00上原来所有逻辑卷lv。镜像前可以用vgdisplay查看一下vg00下有多少个逻辑卷。
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol5 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol6 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol7 /dev/dsk/c2t3d0s2
lvextend -m 1 /dev/vg00/lvol8 /dev/dsk/c2t3d0s2
命令执行情况，根据每个LV里的PE决定mirror时间。
# lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c2t3d0s2
The newly allocated mirrors are now being synchronized. This operation will
take some time. Please wait ....
9、 改变启动文件，镜像自动切换
# echo "boot vmunix -lq" > /tmp/AUTO.lq
# efi_cp -d /dev/rdsk/c2t3d0s1 /tmp/AUTO.lq /EFI/HPUX/AUTO
# efi_cp -d /dev/rdsk/c2t1d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri
# efi_cp -d /dev/rdsk/c2t3d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.alt
# cat /tmp/AUTO.pri
# cat /tmp/AUTO.alt
AUTO.pri,AUTO.alt信息是一致的。
10、核实DBRA已经更新
# lvlnboot –v
11、增加EFI primary/high available
设置引导路径
# setboot -p 0/4/1/0.0.0.1.0 <-- Set primary disk 主盘
# setboot -h 0/4/1/0.0.0.3.0 <-- Set mirror disk 备盘
# setboot -b on <-- Set autoboot on
# lvlnboot -v （查看启动信息）
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c2t1d0s2 (0/4/1/0.0.0.1.0) -- Boot Disk
/dev/dsk/c2t3d0s2 (0/4/1/0.0.0.3.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c2t1d0s2
/dev/dsk/c2t3d0s2
Root: lvol3 on: /dev/dsk/c2t1d0s2
/dev/dsk/c2t3d0s2
Swap: lvol2 on: /dev/dsk/c2t1d0s2
/dev/dsk/c2t3d0s2
Dump: lvol2 on: /dev/dsk/c2t3d0s2, 0
另外做了一下这样的操作，不知道是否必要？？
lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2
lvlnboot -r /dev/vg00/lvol3
12、查看启用信息
# setboot
Primary bootpath : 0/4/1/0.0.0.1.0
HA Alternate bootpath : 0/4/1/0.0.0.3.0
Alternate bootpath : 0/4/2/0
Autoboot is ON (enabled)
13、重新引导并测试
#shutdown –ry 0
在启用菜单中选择备用路径菜单 HA Alternate bootpath |
