V-5-1-663 Duplicate virtual device number
hi folks here is my case
Storage XP24K
Business copy setup
OS Solaris 10
Verital 4.1
Business copy is running between a production server and backup server using xp24k
when the disk groups are imported back on backup server after BC from the prduction server
following error is reported everytime from veritas on one of the DGs and only for some five volumes everytime.
Dec 24 08:51:37 olap vxvm:vxconfigd: [ID 401873 daemon.warning] Volume SYSTEM remapped from 244,113000 to 244,131070
Dec 24 08:51:37 olap vxvm:vxconfigd: [ID 732237 daemon.warning] Volume ACCHEAD_2002 remapped from 244,113003 to 244,131069

Dec 24 08:51:37 olap vxvm:vxconfigd: [ID 323854 daemon.warning] Volume USERS remapped from 244,113002 to 244,131066
Some more usefull outputs are as following
ON Backup Server:
root@olap # grep vxio /etc/name_to_major
vxio 244
vxprint -g post_master15k_dg -mpvsh SYSTEM|grep minor
root@olap # vxprint -g post_master15k_dg -mpvsh SYSTEM|grep minor
minor=113000
forceminor=off
minor=-1
minor=-1
minor=-1
minor=-1
vxprint -g post_master15k_dg -mpvsh ACCHEAD_2002|grep minor
root@olap # vxprint -g post_master15k_dg -mpvsh ACCHEAD_2002|grep minor
minor=113003
forceminor=off
minor=-1
minor=-1
ON Production server:
root@sp6800a # grep vxio /etc/name_to_major
vxio 265
root@sp6800a # vxprint -g post_master15k_dg -mpvsh SYSTEM|grep minor
minor=113000
forceminor=off
minor=-1
minor=-1
minor=-1
minor=-1
root@sp6800a # vxprint -g post_master15k_dg -mpvsh ACCHEAD_2002|grep minor
minor=113003
forceminor=off
minor=-1
minor=-1
Minor numbers are same on both the servers for all hte other volumes( more then 100) in the DG.
