HPUX更换故障硬盘及系统引导区损坏故障恢复过程

HPUX更换故障硬盘及系统引导区损坏故障恢复过程一、故障前现象

服务器操作系统中VG00卷组中一个磁盘报错，不能识别，信息如下：vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c4t6d0":The specified path does not correspond to physical volume attached to this volume group vgdisplay: Warning: couldn't query all of the physical volumes.

根据该信息查找磁盘路径为：1/0/0/3/0.6.0，对应官方文档图片可知需要该故障硬盘为左上角位置：

并且查看物理服务器外观，可见CELL1板卡上的HBA卡状态灯未亮，初步判断为HBA 卡故障，需要更换。

二、更换步骤

1、关闭主机rac节点

2、关闭HA上的包，先确认包名

scgf-l[/]#cmviewcl

CLUSTER STATUS

GFZF_RAC up

NODE STATUS STATE

scgf-k up running

PACKAGE STATUS STATE AUTO_RUN NODE

gfzf1 up running enabled scgf-k

NODE STATUS STATE

scgf-l up running

PACKAGE STATUS STATE AUTO_RUN NODE

gfzf2 up running enabled scgf-l

关闭包：

#cmhaltpkg gfzf2

再次确认双机运行情况cmviewcl

3、确认/dev/dsk/c4t6d0物理位置：1/0/0/3/0.6.0

#ioscan –funC disk

disk 2 1/0/0/3/0.6.0 sdisk CLAIMED DEVICE HP 146 GST3146707LC /dev/dsk/c4t6d0 /dev/rdsk/c4t6d0

4、根据官方图片确认实际物理硬盘位置为左上。

5、确认pv上的lv,如下：

#pvdisplay –v /dev/dsk/c4t6d0（由于该PV已经故障，不能使用该命令查看）

通过一下命令逐个核对lv信息，确认该lv是否存在镜像在故障PV上：

scgf-l[/]#lvdisplay -v /dev/vg00/lvol*|more

scgf-l[/]#lvdisplay -v /dev/vg00/oracle|more

scgf-l[/]#lvdisplay -v /dev/vg00/swap |more

6、查看引导信息，无法列出

#lvlnboot –v

7、摘除分区

#lvreduce -m 0 /dev/vg00/lvol1 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol2 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol3 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol4 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol5 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol6 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol7 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/lvol8 /dev/dsk/c4t6d0

#lvreduce -m 0 /dev/vg00/oracle /dev/dsk/c4t6d0

-----------------------------------------------------------------------------------------------------------------------------------

由于该PV已经故障，VG无法识别，使用以上命令删除时不能成功，需要用一下强制删除方式进行：

执行一下命令，查看故障磁盘PV的key，然后通过key进行删除：

scgf-l[/bea/bea815]#lvdisplay -v -k /dev/vg00/lvol1|more
