V-5-1-663Group ewic04-o-arch-dg: Duplicate virtual device number(s):
Aug 217:05:08 fwewic03a vxvm:vxconfigd: [ID 702911 daemon.warning]
Volumeewic04-o-arch-v01 remapped from 322,21000 to 322,131070
ERROR CODE/MESSAGE:
-V-5-1-663Group ewic04-o-arch-dg: Duplicate virtual device number(s)
WHY DOESTHIS HAPPEN:
RESOLUTION:
The base minor number for a diskgroup can be modified using
"vxdg reminor " command.
Example: To change the minor number for diskgroup dle.
#ls -l/dev/vx/dsk/dle
brw------- 1root root 75, 27000 Feb 14 11:31 vol1
#vxdgreminor dle 48000
#ls -l/dev/vx/dsk/dle
brw------- 1root root 75, 48000 Mar 9 10:58 vol1
So fore wic04-o-arch-dg :
/dev/vx/dsk/ewic04-o-arch-dg:
total4
drwxr-xr-x 2root root 512 Aug 2 17:05 .
drwxr-xr-x14 root root 512 Aug 2 17:05 ..
brw------- 1root root 322, 21001 Aug 2 17:05 ewic04-o-arch-v01
brw------- 1root root 322, 21001 Aug 2 17:05 ewic04-o-arch-v02
For some reason both luns above had 322, 21001
brw------- 1root root 322, 131070 Aug 2 17:05 ewic04-o-arch-v01
#vxdgreminor ewic04-o-arch-v01 21002
EXAMPLE OF AREMINOR:
I created a diskgroup, file system, and mounted it. I also copied data to the newly created volume.

# ls-l

brw------- 1root root 299, 37000 Aug 13 15:58 timvol01
Now I deported it, and imported timdg.
# umount /timvol01
# vxdg deport timdg
# vxdg import timdg
# ls -l //dev/vx/dsk/timdg
total0
brw------- 1root root 299, 21000 Aug 13 16:21 timvol01
As you can see the diskgroup has the new minor number.
