superdome 维修一例

[夏末秋初111]

 环境为：两台superdome+一台XP1024 操作：换上新的FC card, 系统可以启动，但是有新的报错，如下： vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk /c10t0d3": The path of the physical volume refers to a device that does not exist, or is not configured into the kernel. vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk /c10t0d4": The path of the physical volume refers to a device that does not exist, or is not configured into the kernel. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk /c10t0d5": The path of the physical volume refers to a device that does not exist, or is not configured into the kernel. 无法找到原先有的硬盘，系统要挨个检查，主机连着XP上的1200多个硬盘，查完要等到猴年马月。 解决： 1，进MP ，CM， RS，重启主机。 2，启动时进入单用户。（hpux -is) 3, #mount vg00, 把/etc/lvmrc 文件中"AUTO_VG_ACTIVATE=1" 改为“AUTO_VG_ACTIVATE=0” 4，#strings /etc/lvmtab,检查有多少个VG。 5，系统里有的VG都要export vg map 文件出来。（#vgexport -v -s -p -m /tmp/vg01.map /dev/vg01) 6，#export /dev/vg01 (所有VG)，重启。 7，此时启动不会去检查VG的那些硬盘了，可以进系统。 # mkdir /dev/vg01 # mknod /dev/vg01/group c 64 0x040000 # vgimport -s -v -m /tmp/hp/vg01.map /dev/vg01 # vgchange -a y vg01 8，一切OK，不过不要忘了/etc/lvmrc 文件中的“AUTO_VG_ACTIVATE=0”改回来哦，不然用户下次重启就出问题喽。
