vxvm对UNKNOWN ERROR WHILE WRITING VTOC得处理

westlife521

在VERITAS Volume Manager更换硬盘时，使用vxdiskadm  #4  和 #5选项报：

UNKNOWN ERROR WHILE WRITING VTOC

Continue with operation? [y,n,q,?] (default: y)

     UNKNOWN ERROR WHILE WRITTING VTOC
     dd: /dev/rdsk/c0t0d0s0: open: I/O error
     UNKNOWN ERROR WHILE WRITTING VTOC
     UNKNOWN ERROR WHILE WRITTING VTOC

     /etc/vx/bin/vxbootsetup rootdisk
     UNKNOWN ERROR WHILE WRITTING VTOC
     dd: /dev/rdsk/c2t0d0s0: open: I/O error
     UNKNOWN ERROR WHILE WRITTING VTOC

解决办法：

This example shows the procedure for replacement of system disk c0t0d0. The operation is to initialize disk device c0t0d0 and to then use that device to replace the removed or failed rootdisk.

Make sure system is bootable off mirrored disk.

1. Disassociate all mirrors located on c0t0d0:

     # vxplex dis opt-01 rootvol-01 swapvol-01 usr-01 var-01

2. Remove disassociated plexes:

     # vxedit -rf rm opt-01 rootvol-01 swapvol-01 usr-01 var-01

3. Remove disk from rootdg:

     # vxdg rmdisk rootdisk

4. Remove disk out of Volume manager control:

     # vxdisk rm c0t0d0s2

5. Format disk, zero out all partitions except partition 2 and write new label:

     # format
         -> c0t0d0s2
           -> partition
             -> zero out all partitions except partition 2.
               -> label

6. Check newly written partition table with prtvtoc /dev/dsk/c0t0d0s2:

       Only partition 2 [s2] should be visible.

7. Bring c0t0d0 under volume manager control:

     # /etc/vx/bin/vxdisksetup -i c0t0d0

8. Add disk to rootdg:

     # vxdg -g rootdg adddisk rootdisk=c0t0d0s2

9. Check that c0t0d0 is member of rootdg:

     # vxdisk list

10. Mirror rootvol:

      # /etc/vx/bin/vxrootmir rootdisk

11. Check result:

      # vxprint -ht

12. Check that all Volume manager tasks have finished:

      # vxtask list

13. Make certain that the new disk is bootable by running the command

      # vxbootsetup -g rootdg rootdisk

13. Shutdown system

14. Boot off c0t0d0

15. If successful, mirror the rest of system disk one partition at a time: [swapvol, usr, var, opt]

      # vxassist -g rootdg mirror swapvol rootdisk

16. Check result:

      # vxprint -ht and vxtask list

17. Once all volume manager tasks have finished, shutdown the system and boot off c0t0d0.

之前在换根盘时，遇到过这个问题，现在拿出来跟大家分享，希望对您有帮助



后来得知是vxvm 3.0.x 得一个BUG 打相应得补丁就可以解决

不错，步骤很清析。
