HP11.31磁盘镜像制作过程

原创 Linux操作系统 作者：tonyzhou_cn 时间：2012-12-02 16:00:54 0 删除 编辑

1、查看vg00：
   vgdisplay -v /dev/vg00 ;
VG Name                     /dev/vg00
VG Write Access             read/write    
VG Status                   available           
PE Size (Mbytes)            32             
Total PE                    4347   
Alloc PE                    1134   
Free PE                     3213  
   --- Logical volumes ---
   LV Name                     /dev/vg00/lvol1
   LV Name                     /dev/vg00/lvol2
   LV Name                     /dev/vg00/lvol3
   LV Status                   available/syncd          
   LV Name                     /dev/vg00/lvol4
   LV Name                     /dev/vg00/lvol5
   LV Name                     /dev/vg00/lvol6
   LV Name                     /dev/vg00/lvol7
   LV Name                     /dev/vg00/lvol8
    --- Physical volumes ---
   PV Name                     /dev/disk/disk3_p2

2、查看磁盘：
# ioscan -m lun | grep disk
disk      3  64000/0xfa00/0x1   esdisk  CLAIMED     DEVICE       online  HP 146 GST3146707LC      
                      /dev/disk/disk3      /dev/disk/disk3_p2（已用）   /dev/rdisk/disk3     /dev/rdisk/disk3_p2
                      /dev/disk/disk3_p1   /dev/disk/disk3_p3   /dev/rdisk/disk3_p1  /dev/rdisk/disk3_p3
disk      5  64000/0xfa00/0x3   esdisk  CLAIMED     DEVICE       online  HP 146 GST3146707LC      
                      /dev/disk/disk5   /dev/rdisk/disk5
        即：
根盘是：/dev/rdisk/disk3
镜像盘是：/dev/rdisk/disk5
即我安装OS是，只用了/dev/disk/disk3，没有使用/dev/disk/disk5。

3、# ioscan -kfnC disk
Class     I  H/W Path       Driver S/W State   H/W Type     Description
=======================================================================
disk      0  1/0/0/3/0.6.0  sdisk   CLAIMED     DEVICE       HP 146 GST3146707LC
                           /dev/dsk/c0t6d0     /dev/dsk/c0t6d0s2   /dev/rdsk/c0t6d0    /dev/rdsk/c0t6d0s2
                           /dev/dsk/c0t6d0s1   /dev/dsk/c0t6d0s3   /dev/rdsk/c0t6d0s1  /dev/rdsk/c0t6d0s3
disk      1  1/0/0/3/1.2.0  sdisk   CLAIMED     DEVICE       _NEC    DVD_RW ND-3550A
                           /dev/dsk/c1t2d0   /dev/rdsk/c1t2d0
disk      2  1/0/1/1/0/1/1.6.0  sdisk   CLAIMED     DEVICE       HP 146 GST3146707LC
                           /dev/dsk/c3t6d0   /dev/rdsk/c3t6d0

4、# ioscan -kfNC disk
Class     I  H/W Path  Driver S/W State   H/W Type     Description
===================================================================
disk      3  64000/0xfa00/0x1  esdisk   CLAIMED     DEVICE       HP 146 GST3146707LC
disk      4  64000/0xfa00/0x2  esdisk   CLAIMED     DEVICE       _NEC    DVD_RW ND-3550A
disk      5  64000/0xfa00/0x3  esdisk   CLAIMED     DEVICE       HP 146 GST3146707LC
5、编写磁盘的table文件，并导入到mirror盘：
   # mkdir /tmp/mirror/  
# vi /tmp/mirror/table  输入以下内容：
 3
EFI 500MB
HPUX 100%
HPSP 400MB
 
6、#idisk -wf /tmp/mirror/table /dev/rdisk/disk5
idisk version: 1.44
********************** WARNING ***********************

7、查看是否导入成功：
#idisk /dev/rdisk/disk5
 idisk version: 1.44

        Ending Lba Hi              = 0x0

Legacy MBR (MBR Signatures in little endian):
   MBR Signature = 0x40497d99

8 、安装分好区的设备文件；
# insf  -eCdisk

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 -e -l /dev/rdisk/disk5
9、修改两块磁盘的引导模式：
（-lq 不进行quorum 检查，当一个VG 只有少于等于50%的硬盘可以正常访问时，默认情况下就不能被激活，加这个参数以后就可以强行激活，在配置了根盘镜像的情况下经常会用到这个参数）。
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk3;  根盘。
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk5;  镜像盘。
# efi_cp -d /dev/rdisk/disk3_p1 -u /efi/hpux/auto /dev/tty;    --查看是否修改成功；
    
# efi_cp -d /dev/rdisk/disk5_p1 -u /efi/hpux/auto /dev/tty;    --查看是否修改成功；
            
10、 将新盘（镜像盘）的p2分区格式化成PV：
# pvcreate -fB /dev/rdisk/disk5_p2;
          Physical volume "/dev/rdisk/disk5_p2" has been successfully created.
11、 将新盘的p2分区加入到VG00中：
# vgextend vg00 /dev/disk/disk5_p2  ;
 
12 、镜像VG00中的所有LV；
# for lv in /dev/vg00/lvol*
> do
> lvextend -m 1 $lv /dev/disk/disk5_p2;
> done
注意：这里 > 是命令符合，回车后自动产生的。
       
13、恢复所有的BDRA信息：
# lvlnboot -R
           Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
14、 查看镜像情况：
      # lvlnboot  -v 
          
15、修改引导配置文件：
# vi /stand/bootconf
l  /dev/disk/disk3_p2         字母“l”（L 的小写形式）代表 LVM 。
2  /dev/disk/disk5_p2

16、设置系统引导的设备及顺序：
# ioscan -fnCdisk
Class     I  H/W Path       Driver S/W State   H/W Type     Description
=======================================================================
disk      0  1/0/0/3/0.6.0  sdisk   CLAIMED     DEVICE       HP 146 GST3146707LC
                           /dev/dsk/c0t6d0     /dev/dsk/c0t6d0s2   /dev/rdsk/c0t6d0    /dev/rdsk/c0t6d0s2
                           /dev/dsk/c0t6d0s1   /dev/dsk/c0t6d0s3   /dev/rdsk/c0t6d0s1  /dev/rdsk/c0t6d0s3
disk      1  1/0/0/3/1.2.0  sdisk   CLAIMED     DEVICE       _NEC    DVD_RW ND-3550A
                           /dev/dsk/c1t2d0   /dev/rdsk/c1t2d0
disk      2  1/0/1/1/0/1/1.6.0  sdisk   CLAIMED     DEVICE       HP 146 GST3146707LC
                           /dev/dsk/c3t6d0     /dev/dsk/c3t6d0s2   /dev/rdsk/c3t6d0    /dev/rdsk/c3t6d0s2
                           /dev/dsk/c3t6d0s1   /dev/dsk/c3t6d0s3   /dev/rdsk/c3t6d0s1  /dev/rdsk/c3t6d0s3
         # ioscan -m lun | grep disk
 
         # ioscan -m lun /dev/disk/disk3
         # ioscan -m lun /dev/disk/disk5
# setboot -p 1/0/0/3/0.6.0    ,p表示主引导设备
# setboot -h 1/0/1/1/0/1/1.6.0     ,h表示备用引导设备
17、重新启动系统，验证镜像是否成功，查看是否从设定的设备磁盘引导：
        # shutdown -ry 0     重启时选择所要启动的路径。
# grep "Boot" /var/adm/syslog/syslog.log
