V-5-1-663 Duplicate virtual device number(s): issue

[Ajay S]

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 879036 daemon.warning] Volume CDR_JULY_2008_F1 remapped from 244,113004 to 244,131068
Dec 24 08:51:37 olap vxvm:vxconfigd: [ID 904903 daemon.warning] Volume SPPOST_TAB_08 remapped from 244,113001 to 244,131067
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.

sounts like a Minor numbers problem,
are you importing a vg on a other name?

check het minor number that you are importing and see if
ll /dev/* |grep "minor numbre"
is giving a response....

[F Verschuren]

sorry you have a sun OS so maybe the device files are someware els.....

[Ajay S]

the error message is from VxVM not from Solaris.

minor numbers of all the other non conflicting volumes under the same DG are also same on both backup and production server.
