在HPUX 11iV3系统中更换已镜像的非根磁盘(原创)

情景 1如果要替换的磁盘已做了镜像，推荐如下步骤：1. 删除该磁盘上所有逻辑卷的复件，使用 rmlvcopy 命令或 unmirrorvg 命令。

2. 从卷组中删除该磁盘，使用 reducevg 命令。

3. 使用 rmdev 命令删除该磁盘定义。

4. 物理移除该磁盘。

如果磁盘不是可热交换的（hot-swappable），可能要求重启系统。

5. 使备用的磁盘可用。

如果磁盘是可热交换的（hot-swappble），可运行 cfgmgr；否则，需要重启系统。

6. 把新加的磁盘放入卷组，使用 extendvg 命令。

7. 重建并同步所有逻辑卷的复件，使用 mklvcopy 命令或 mirrorvg 命令。

HP Integrity server HPUX 11.31 Mirroring boot disks贵阳曾凡宏HP Integrity server HPUX 11.31 Mirroring boot disks (1)扯蛋 (1)Itanium mirroring 步骤 (3)Itanium mirroring 全过程 (4)拆除分区的方法 (15)扯蛋开始正题之前先抱怨一下，HP原厂也真不是东西，提供的文档不详细也就罢了，他们竟然提供的文档还是错误的，我无论如何都没有想到用MKBOOT写AUTO语句的时候用到的竟然会是块设备（当然，我不清楚是只写块设备，还是块设备字符设备都要写，不过百分之五十一是只写块设备），虽然在一老外的贴子中提到这里用的是块设备，但我还是选择了相信原厂的文档，坚持了无数次。

原厂就是故意搞错的，信不信由你，反正我信了。

这是种什么行为，这是一种打压第三方的恶劣行径。

害我这两天死皮赖脸的在联通机房折腾了这台新鲜的RX8640十二个小时，管理员一下班就来催我走，还好今天没走，和他拿了钥匙，坚持到了最后，在我快要绝望的时候，我想到了这一点，终于成功了。

安腾11.31的系统改变挺多的，十秒中断那里也算是一个，这里不再是以前的SEA，然后BO ******，而是一个与SETBOOT相关联的可选择式菜单，如图：这里面有个以前没见过的东西，EFI SHELL [BUILT-IN]，相关文章可以在网上找到。

正常情况下，十秒中断后选择启动项后是这样的：而我呢，无数次看到的是这样的：镜像LV的顺序一定要搞对，要不然会出问题的，我一开始图省事一个FOR循环做所有的LV，因为还有一个LV是不规则的命名，所以我用LV*指定了所有的LV。

结果就是：看到没有，镜像盘上的LV的顺序。

这样就会导致：安腾11.31系统最直观的区别应该就是他的设备文件吧。

用-m参数的IOSCAN命令看看：关于磁盘的分区，后面会提到创建分区以及拆除分区的方法。

HP-UX 更换根盘镜像专题方法一1,拆除设备镜像,踢出坏盘.解除镜像：vgdisplay vg00 //查看vg00中的LV的镜像状态。

# mkboot /dev/rdsk/cXtYd0 //创建BOOT区# mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/cXtYd0# mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/cXtYd0给根盘上的所有逻辑卷做镜像，务必从第一个LV开始，按顺序执行，镜像需要一定时间，请耐心等待。

【HPUX 11.31专题】HPUX 11.31系统镜像HPUX 11.23及以后版本与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。

Rootvg更换mirror硬盘描述：两块盘hdisk0 和hdisk1 属rootvg 且做了mirror，有一块硬盘损坏，需要在线更换硬盘。

步骤：1、备份rootvg2、解镜像mirror3、删除坏掉的硬盘4、添加新的硬盘到rootvg5、做镜像mirror6、做同步1、和客户沟通对rootvg进行mksysb备份。

防止意外。

2、执行smitty vg在volume里选择需要除去镜像的卷组，physical vlume name里选择需要去掉的硬盘hdisk1执行reducevg rootvg hdisk1，将hdisk1从卷组rootvg里删除。

执行boslist –a查看列出结果若报错，执行boslist -ad /dev/hd5 hdisk0执行chpv –c hdisk1 清除hdisk1上的引导记录执行boslist –m normal hdisk0执行完了之后查看rootvg状态lsvg –l rootvg看一下lv state ，有无stale状态的文件系统出现。

其中lg_dumplv变为stale的话可以忽略掉。

3、删除坏的硬盘，执行diag——回车——task··选择hot plug task然后hdisk1硬盘灯会长亮。

更换硬盘4、添加新的硬盘到rootvg执行cfgmgr –v，扫描到新加入的硬盘lspv查看执行extendvg rootvg hdisk1将hdisk1加入到rootvg中。

在执行mirror vg之前要查看rootvg的quroum是否更改，一般建议执行chvg –Qn rootvg，将其设为disabled状态执行smit vg需要更改的选项如下图所示。

完毕之后，执行boslist –m normal hdisk0 hdisk1将引导区加入到hdisk0和hdisk1上。

6、做同步执行syncvg -v rootvg命令可以做rootvg的同步。

关于HP UX 11.31系统更换系统盘的体会贵阳曾凡宏HP UX 11.31系统变化最为明显的是其磁盘设备名的变化。

新的磁盘设备名为永久设备名，其设备名与LUN的WorldWide Identifier (WWID)绑定。

更换交换机，HBA卡等都不会使设备文件名发生改变。

HP UX 11.31 系统更换系统盘的程序不再和11.11、11.23一样。

在拔除故障盘后以及插入新盘前，需要输入一条命令”rmsf –a /dev/disk/disk**”删除与之相关的所有的设备文件，插入硬盘后重新扫描一下就OK了。

在出意外的情况下，你会无法删除原先的设备文件，这时你把新的硬盘插入，虽然能看得到新硬盘的描述，但是硬盘的状态会显示”NO_HW”，这是因为占用了这条LUNPA TH的设备文件名绑定的是被拔除的硬盘的WWID，所以无法识别到新的硬盘，所以呢，我们要做的就是更改一下绑定的WWID，用这个命令“scsimgr replace_wwid –D /dev/rdisk/disk** ds f”好使。

将这个新的WWID绑定到原先的设备文件名上，然后才能正常识别到更换上去的硬盘，但是这样的话，换上去的盘就不能使用原先的设备名。

当然，有解决的办法，后面有提到的。

贵州联通的一块RP7420上的系统盘故障后，我前后去了三次，都没有更换成功，一开始以为是硬盘的原因，结果经过一晚的试验，发现硬盘都是正常的。

今天在刘工的帮助下，终于发现这是WWID的原因。

感谢刘工。

感谢GOOGLE。

归根结底，还是自己学艺不精，没能与时俱进。

这两天因为自己技术的落后，让张和琳增添了不少麻烦，在此向张和琳表示感谢。

下面是更换硬盘的日志：有两种情况，一种是正常的，一种是非正常的。

碰到镜像根盘鬼盘的换盘步骤如下：1. #vgreduce -f /dev/vgXX2. #lvreduce -A n -m 0 -k /dev/vgXX/lvolX /dev/dsk/cXtYdZ3. replace disk4. #pvcreate -B /dev/rdsk/cXtYdZ5. #mkboot -l /dev/rdsk/cXtYdZ6. #mkboot -a "hpux -lq(;0)/stand/vmunix" /dev/rdsk/cXtYdZ7. #vgextend /dev/vgXX /dev/dsk/cXtYdZ8. #lvextend -m 1 /dev/vgXX/lvolX /dev/dsk/cXtYdZ...9. #setboot -v#lvlnboot -v检查并设置启动配置注：1、为保证前后lvmtab 内容不变，最好先对lvmtab 文件进行备份2、在出现鬼盘的情况下，可以尝试备份lvmtab 后，用#lvscan 命令重建lvmtab 文件问：What is a Ghost Disk?答：PV that has failed or not even physically connected but still recorded in the lvmtab. A Ghost Disk is usually indicated by #vgdisplay reporting more Current PVs(recorded in lvmtab) than Active PVs(recorded in kernel).问：鬼盘的换盘步骤？答：一般换盘步骤是在换完硬盘后用命令#vgcfgrestore -n /dev/vgXX /dev/rdsk/cXtYdZ在新盘写入VGRA 和PVRA 信息但是由于lvmtab和kernel里的PV信息不对，会提示“Mismatch between the backup file and the runningkernel！”假如你100%肯定备份的vg信息是对的，可以加参数#vgcfgrestore -R必须先释放pv才能更换#vgreduce -f /dev/vgXXTo remove all PVs that are “free”, i.e. there is no LV having extents on that PV. Otherwise, if the PV is not free, #vgreduce -f reports an extents map to identify the associated LVs.You must free all PEs using lvreduce/lvremove before the PV can be removed.Check LV state#lvdisplay -v /dev/vgXX/lvolX假如lv做了镜像#lvreduce -A n -m 0 -k /dev/vgXX/lvolX /dev/dsk/cXtYdZ删除坏盘镜像假如lv没有做镜像#lvremove -A n /dev/vgXX/lvolX没有做镜像的话，lv的数据会丢失〈参数解释〉--------------------------------------------------------------------------------vgreduce-f vg_name force reduction of missing physical volume(s) in agiven volume group. This option does not requirea physical volume (PV) to be supplied on thecommand line. vgreduce obtains the name of eachphysical volume (PV) belonging to the volume groupfrom the file /etc/lvmtab. It then reads the LVMstructures from each PV and compares these withthat held by the kernel to work out which PVs aremissing. PVs which are missing will be candidatesfor removal. If all the physical extents on themissing PV are free then it will be removed fromthe volume group. Otherwise vgreduce will reportthe physical to logical extent mapping. Formissing PVs, which have extents in use, you mustfree up all the extents by using lvreduce(1M) orlvremove(1M) and re-run vgreduce with the -foption. This option is most commonly used whenthe vgdisplay(1M) command shows "Cur PV" higherthan "Act PV" and all of the PVs belonging to thevolume group are attached. This option only workson PVs and not on links.example: vgreduce -f /dev/vg01--------------------------------------------------------------------------------lvreduce -k This option should be used only in thespecial instance when you want to reduce amirrored logical volume on a physical volumethat is missing or has failed.Use this option with the -m option.example: lvreduce -m 0 -k /dev/vg01/lvol1 /dev/dsk/c1t0d0附：在没碰到鬼盘的情况下，换镜像根盘的步骤如下1.vgcfgrestore -n /dev/vg00 /dev/rdsk/c3t6d02.vgchange -a y -q n vg003.mkboot -l /dev/dsk/cXtYdZ ; lifls -l /dev/dsk/cXtYdZ4.mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c3t6d0 ; lifcp /dev/dsk/cXtYdZ:AUTO -5.lvlnboot -v (check & set lvlnboot)6.pvdisplay -v <replaced disk> | grep current7.vgsync vg008.lvdisplay -v $(find /dev/vg00 -type b) | grep stale | wc -l (check the progress of the sync)。
