配置mirror for HP-UX

maxz

A．镜像前的情况：
     ．先确定如下情况：
       主磁盘是：     /dev/dsk/c2t1d0
       镜像的磁盘是： /dev/dsk/c3t0d0
            （用命令“ ioscan –fnC disk”可以查看）
       确定系统是否安装MirrorDisk/UX：用“swlist”查看

           
#
# uname -a
HP-UX grainte B.11.11 U 9000/800 283889281 unlimited-user license


# ioscan -fnC disk

                           /dev/dsk/c3t0d0   /dev/rdsk/c3t0d0
#
．使用参数“-B”创建一个用于镜像的可引导的LVM磁盘：
#  pvcreate  -f  -B  /dev/rdsk/c3t0d0
Physical volume "/dev/rdsk/c3t0d0" has been successfully created.

将上一步LVM磁盘添加到根卷组中：
# vgextend   /dev/vg00  /dev/dsk/c3t0d0
Volume group "/dev/vg00" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

．将新磁盘制作成引导磁盘，需要注意的是要使用字符设备：
# mkboot  /dev/rdsk/c3t0d0

# bdf
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg00/lvol3     229376   85056  143232   37% /
/dev/vg00/lvol1     314736   60928  222328   22% /stand
/dev/vg00/lvol8    8388608  433896 7892784    5% /var
/dev/vg00/lvol7    4194304 1221328 2949784   29% /usr
/dev/vg00/lvol9    20971520  478296 20173068    2% /users
/dev/vg00/lvol4    2097152  159736 1922904    8% /tmp
/dev/vg00/lvol10   20971520 9226748 11561404   44% /oracle
/dev/vg00/lvol6    4194304 1689416 2485344   40% /opt
/dev/vg00/lvol5    2097152    2720 2078128    0% /home

将镜像到可引导的磁盘。要确保vg00中的所有设备均已镜像，
要确保lv0l1是镜像的第一逻辑卷。若lvol1不是第一逻辑卷，系统就不能镜像启动。

．拷贝正确的AUTO文件到新的LIF区，注意使用字符设备：
mkboot -a 'hpux -lq(;0) /stand/vmunix' /dev/rdsk/c3t0d0

．指定引导逻辑卷、根逻辑卷、主交换逻辑卷（用swapinfo确定交换逻辑卷在什么地方）、转储逻辑卷,为根和交换镜像拷贝更新包含在BDRA中等启动信息：

# lvlnboot  -b  /dev/vg00/lvol1
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
#  lvlnboot -r /dev/vg00/lvol3
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
#   lvlnboot -s /dev/vg00/lvol2
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
#  lvlnboot -d /dev/vg00/lvol2
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

.恢复所有的BDRA信息：
# lvlnboot  -R
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

．确定引导逻辑卷、根逻辑卷、主交换逻辑卷以及转储逻辑卷的设置：（检查镜像正确与否）

# lvlnboot  -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
        /dev/dsk/c2t1d0 (0/1/1/0.1.0) -- Boot Disk
        /dev/dsk/c3t0d0 (0/1/1/1.0.0) -- Boot Disk
Boot: lvol1     on:     /dev/dsk/c2t1d0
                        /dev/dsk/c3t0d0
Root: lvol3     on:     /dev/dsk/c2t1d0
                        /dev/dsk/c3t0d0
Swap: lvol2     on:     /dev/dsk/c2t1d0
                        /dev/dsk/c3t0d0
Dump: lvol2     on:     /dev/dsk/c2t1d0, 0

  ．显示当前的主引导路径和替代引导路径：

# setboot
Primary bootpath : 0/1/1/0.1.0
Alternate bootpath : 0/1/1/1.0.0　＃这个地方的路径一定要与/dev/dsk/c3t0d0 (0/1/1/1.0.0) -- Boot Disk的一样。否则用下面命令更改

strings /etc/lvmtab

setboot -a 0/1/1/1.0.0
然后重启服务器，在控制台上用选择第二块硬盘重启：
bo alt
n


Autoboot is ON (enabled)
Autosearch is ON (enabled)

这个镜像好象有问题的

fly_sky418

这样重起机器从镜像盘是启动不起来的

fly_sky418

mkboot  /dev/rdsk/c3t0d0要加上-l参数要为新盘写入LIF区

fly_sky418

还要做一步mkboot -a "hpux -lq(;0) /stand/vmunix"为新的物理盘设置内核引导路径及取消引导仲裁机制
