Handling Conflicting Configuration Copies in a Disk Group
154 VERITAS Volume Manager Administrator’s Guide
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 169 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
In this example, the disk group has four disks, and is split so that two disks appear to be
on each side of the split.
