1、环境：系统现有两块磁盘，一块作为主盘，一块作为镜像盘用ioscan-nfCdisk可以查看到两个磁盘/dev/dsk/c0t0d0        //此盘为主盘/dev/dsk/c0t2d0        //此盘将作为镜像盘用swinstall–lbundle查看系统是否安装MirrorDisk/UX镜像的步骤：1、pvcreate -f -B /dev/rdsk/c0t2d0//使用参数“-B”创建一个用于镜像的可引导的LVM磁盘：2、vgextend/dev/vg00/dev/dsk/c0t2d0//将上一步的LVM磁盘添加到根卷组中3、mkboot/dev/c0t2d0 

2、               //将新磁盘制作成为可引导的磁盘4、lvextend -m 1 /dev/vg00/lvol1  /dev/dsk/c0t2d0   lvextend -m 1 /dev/vg00/lvol2  /dev/dsk/c0t2d0   lvextend -m 1 /dev/vg00/lvol3  /dev/dsk/c0t2d0   lvextend -m 1 /dev/vg00/lvol4  /dev/dsk/c0t2d0   lvextend -m 1 /dev/vg00/lvol5  /dev/dsk/c0t2d0   lvextend -m 1 /

3、dev/vg00/lvol6  /dev/dsk/c0t2d0   lvextend -m 1 /dev/vg00/lvol7  /dev/dsk/c0t2d0   lvextend -m 1 /dev/vg00/lvol8  /dev/dsk/c0t2d0   //将VG00中的所有设备都镜像到镜像盘，-m1表示拷贝一份镜像，如果文件系统较大，等待时间可能会长一点，如下：#lvextend-m1/dev/vg00/lvol1            Thenewlyallocatedmirrorsarenowbeingsynchronized.Thisoperationwillt

5、/vg00/lvol2"hasbeensuccessfullyextended.VolumeGroupconfigurationfor/dev/vg00hasbeensavedin/etc/lvmconf/vg00.conf第5步：拷贝正确的AUTO文件到新的LIF区#mkboot-a"hpux-lq(;0)/stand/vmunix"/dev/dsk/c0t0d0#mkboot-a"hpux-lq(;0)/stand/vmunix"/dev/dsk/c0t2d0 第6步：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

6、镜像拷贝更新包含在BDRA中等启动信息：#lvlnboot-b/dev/vg00/lvol1VolumeGroupconfigurationfor/dev/vg00hasbeensavedin/etc/lvmconf/vg00.conf#lvlnboot-r/dev/vg00/lvol3VolumeGroupconfigurationfor/dev/vg00hasbeensavedin/etc/lvmconf/vg00.conf#lvlnboot-s/dev/vg00/lvol2VolumeGroupconfigurationfor/dev/vg00hasbeensavedin/

7、etc/lvmconf/vg00.conf#lvlnboot-d/dev/vg00/lvol2VolumeGroupconfigurationfor/dev/vg00hasbeensavedin/etc/lvmconf/vg00.conf第7步：恢复所有的BDRA信息#lvlnboot-R VolumeGroupconfigurationfor/dev/vg00hasbeensavedin/etc/lvmconf/vg00.conf第8步：确定引导逻辑卷、根逻辑卷、主交换逻辑卷以
