  Oracle：  Oracle 10gR2（64）

故障现象：

     smit chfs 扩展 “ /" 时，提示找不到”device “，不能扩展；在rootvg 扩展pv 后，后来pv 被破坏，导致ODM出错

1、查看rootvg

[root@aix216 /]#lsvg -p rootvg

rootvg:

PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION

hdisk0            active            546         161         107..00..00..12..42

0516-304 : Unable to find device id 0000c908116d1325 in the Device

       Configuration Database.

[root@aix216 /]#

----尝试解决

[root@aix216 /]#redefinevg -d hdisk0 rootvg

[root@aix216 /]#lsvg -p rootvg

rootvg:

Reduces volume group size by removing a physical volume.

2、从rootvg 中删除hdisk0

------ reducevg 删除pv 后，hd5 被删除

[root@aix216 /]#reducevg rootvg 0027713e1b5646e5

0516-016 ldeletepv: Cannot delete physical volume with allocated

       partitions. Use either migratepv to move the partitions or

       reducevg with the -d option to delete the partitions.

[root@aix216 /]#reducevg -d rootvg 0027713e1b5646e5

0516-914 rmlv: Warning, all data belonging to logical volume

       hd5 on physical volume 0027713e1b5646e5 will be destroyed.

rmlv: Do you wish to continue? y(es) n(o)?

y

0516-1246 rmlv: If hd5 is the boot logical volume, please run 'chpv -c '

       as root user to clear the boot record and avoid a potential boot

       off an old boot p_w_picpath that may reside on the disk from which this

       logical volume is moved/removed.

rmlv: Logical volume hd5 is removed.

0516-1734 rmlv: Warning, savebase failed.  Please manually run 'savebase' before rebooting.

0516-914 rmlv: Warning, all data belonging to logical volume

       fwdump on physical volume 0027713e1b5646e5 will be destroyed.

rmlv: Do you wish to continue? y(es) n(o)?

yes

0516-1008 rmlv: Logical volume fwdump must be closed.  If the logical volume

       contains a filesystem, the umount command will close the LV device.

0516-1734 rmlv: Warning, savebase failed.  Please manually run 'savebase' before rebooting.

0516-884 reducevg: Unable to remove physical volume 0027713e1b5646e5.

0516-1734 reducevg: Warning, savebase failed.  Please manually run 'savebase' before rebooting.

[root@aix216 /]#savebase

[root@aix216 /]#

[root@aix216 /tmp]#lsvg -l rootvg

rootvg:

lv00                jfs        1       1       1    open/syncd    /var/adm/csd

3、重新建立 hd5

重建hd5 ，出错

[root@aix216 /tmp]#mklv -y hd5 -t boot -a e rootvg 1

mklv -y hd5 -t boot -a e rootvg 1

0516-304 lquerypv: Unable to find device id 0000c908116d13250000000000000000 in the Device

       Configuration Database.

       delete some files and try again.

0516-1734 mklv: Warning, savebase failed.  Please manually run 'savebase' before rebooting.

[root@aix216 /tmp]#bosboot -ad /dev/ipldevice

0516-306 lslv: Unable to find  hd5 in the Device

       Configuration Database.

0301-168 bosboot: The current boot logical volume, /dev/hd5,

       does not exist on /dev/hdisk0.

----- 提示：/tmp空间不足，实际/tmp空间很大，尝试删除tmp 下所有的文件

 

[root@aix216 /tmp]#df -m

[root@aix216 /tmp]#bosboot -ad /dev/ipldevice

bosboot: Boot p_w_picpath is 37908 512 byte blocks.

[root@aix216 /tmp]#

6、故障解决

查看rootvg pv ，问题解决

[root@aix216 /tmp]#lsvg -p rootvg

rootvg:

PV_NAME           PV STATE          TOTAL PPs   FREE PPs    FREE DISTRIBUTION
