cbr record of re-created disk group

uid60001
Level 2
We have a system which suffered multiple power failures in last 18 months. One of the oracle backup file system,which has it's own disk group, failed to mount in last a few power failures. Further check, the disk group record in the /etc/vx/cbr/* directory hasn't been updated.  Recreated the diskgroup/volume today[used same disk group name, but different volume name], then; deport and import the disk. The deport/import work OK. I am expect to see new record regarding the disk since export and import action took place, but it is not in /etc/vx/cbr/*.  For the record, this server boot up without a lot of the default system processes running[like the script in rc2.d and rc3.d haven't been run]. I start them with for loop manually, but did not trouble shoot further since the system admin function is belong to other team. Without the cbr on the newly recreated disk group on the system, I suspect the system won't able to recognize the disk group again after another power interrupted crash.

How can I forcefully create a cbr record for this disk group named orabkup?

Hello Dean,

are you sure that vxconfigbackupd is running ? If it is running, how long is it been running ?

As  you mentioned that system has booted without many rc scripts, please note, vxconfigackup has relation with S95vxvm-recover script.

/etc/vx/bin/vxconfigbackupd: This daemon is executed automatically on reboot as part of the /etc/rc2.d/S95vxvm-recover script and will monitor changes to the Volume Manager configuration and automatically records any configuration changes that occur.

If you want to take manual backup:

To back up a single disk group manually :

# /etc/vx/bin/vxconfigbackup  oradg
Start backing up diskgroup oradg to /etc/vx/cbr/bk/oradg.1071722106.138.gopal ..

To back up all disk groups :
# /etc/vx/bin/vxconfigbackup

VxVM vxconfigbackup ERROR V-5-2-3694 Configuration Copy for diskgroup rootdg has
not changed since last backup (Thu Jan 8 15:55:20 EST 2004).  Backup is not necessary.
Start backing up diskgroup datadg to /etc/vx/cbr/bk/datadg.1075436149.168.gopal...

VxVM  NOTICE V-5-2-3100 Backup complete for diskgroup: datadg

VxVM vxconfigbackup ERROR V-5-2-3694 Configuration Copy for diskgroup oradg has
not changed since last backup (Thu Feb 12 16:19:59 EST 2004).  Backup is not necessary.

To back up to an alternative location of the configuration database:

# /etc/vx/bin/vxconfigbackup -l  /tmp/orgdgbck  oradg
Start backing up diskgroup oradg to /tmp/oradgbck/oradg.1071722106.138.gopal ...
VxVM  NOTICE V-5-2-3100 Backup complete for diskgroup: oradg

Hope this helps
