194Creating and administering disk groups

Handling conflicting configuration copies

The following section, “Correcting conflicting configuration information,” describes how to fix this condition.

For more information on how to set up and maintain a remote mirror configuration, see “Administering sites and remote mirrors” on page 431.

Correcting conflicting configuration information

Note: This procedure requires that the disk group has a version number of at least 110. See “Upgrading a disk group” on page 208 for more information about disk group version numbers.

To resolve conflicting configuration information, you must decide which disk contains the correct version of the disk group configuration database. To assist you in doing this, you can run the vxsplitlines command to show the actual serial ID on each disk in the disk group and the serial ID that was expected from the configuration database. For each disk, the command also shows the vxdg command that you must run to select the configuration database copy on that disk as being the definitive copy to use for importing the disk group.

The following is sample output from running vxsplitlines on the disk group newdg:

#vxsplitlines -g newdgThe following splits were found in disk group newdgThey are listed in da(dm) name pairs.Pool 0.c2t5d0 ( c2t5d0 ), c2t6d0 ( c2t6d0 ),

The configuration from any of the disks in this split should appear to be be the same.

To see the configuration from any of the disks in this split, run: /etc/vx/diag.d/vxprivutil dumpconfig /dev/vx/dmp/c2t5d0

To import the dg with the configuration from this split, run: /usr/sbin/vxdg -o selectcp=1045852127.32.olancha import newdg

To get more information about this particular configuration, run: /usr/sbin/vxsplitlines -g newdg -c c2t5d0

Split 1.c2t7d0 ( c2t7d0 ), c2t8d0 ( c2t8d0 ),

The configuration from any of the disks in this split should appear to be be the same.

To see the configuration from any of the disks in this split, run: /etc/vx/diag.d/vxprivutil dumpconfig /dev/vx/dmp/c2t7d0

To import the dg with the configuration from this split, run: /usr/sbin/vxdg -o selectcp=1045852127.33.olancha import newdg

To get more information about this particular configuration, run: /usr/sbin/vxsplitlines -g newdg -c c2t7d0
