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 newdg
The following splits were found in disk group newdg
They 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
