All the disks in the first pool have the same config copies
All the disks in the second pool may not have the same config copies
Number of disks in the first pool: 1
Number of disks in the second pool: 1
To import the disk group with the configuration copy from the first pool, enter
the following command:
# /usr/sbin/vxdg (-s) -o selectcp=1221451925.395.vm2850lx13 import mydg
To import the disk group with the configuration copy from the second pool, enter
the following command:
# /usr/sbin/vxdg (-s) -o selectcp=1221451927.401.vm2850lx13 import mydg
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.
You can specify the -c option to vxsplitlines to print detailed information about
each of the disk IDs from the configuration copy on a disk specified by its disk
access name:
# vxsplitlines -g newdg -c c2t6d0
DANAME(DMNAME) || Actual SSB || Expected SSB
c2t5d0( c2t5d0 ) || 0.1 || 0.0 ssb ids don’t match
c2t6d0( c2t6d0 ) || 0.1 || 0.1 ssb ids match
c2t7d0( c2t7d0 ) || 0.1 || 0.1 ssb ids match
c2t8d0( c2t8d0 ) || 0.1 || 0.0 ssb ids don’t match
Please note that even though some disks ssb ids might match
that does not necessarily mean that those disks’ config copies
have all the changes. From some other configuration copies,
those disks’ ssb ids might not match. To see the configuration
from this disk, run
/etc/vx/diag.d/vxprivutil dumpconfig /dev/vx/dmp/c2t6d0
Based on your knowledge of how the serial split brain condition came about, you
must choose one disk’s configuration to be used to import the disk group. For
example, the following command imports the disk group using the configuration
copy that is on side 0 of the split:
# /usr/sbin/vxdg -o selectcp=1045852127.32.olancha import newdg
When you have selected a preferred configuration copy, and the disk group has
been imported, VxVM resets the serial IDs to 0 for the imported disks. The actual
