Configuring the VDDK logging level
The following NetBackup processes capture VDDK log messages:
bpbkar, bpbkarv, nbrestore
These processes write VDDK messages in the VxMS logs if the VxMS logging level (VxMS_VERBOSE) is 5 or higher. By default, when VXMS_VERBOSE is 5 or higher, the VDDK messages are generated at the highest verbosity.
ncfnbcs, bpVMutil
These processes write VDDK messages in their own log directories if the NetBackup global logging level is 5. By default, when the NetBackup global logging level is 5, the VDDK messages in the ncfnbcs and bpVMutil logs are generated at minimum verbosity.
To change the logging level (verbosity) of the VDDK messages
Check the following on the backup host:
Make sure the VxMS log directory exists and that the VXMS_VERBOSE DWORD is set to 5 or higher.
Make sure the bpVMutil log directory exists and that the NetBackup global logging level is set to 5.
Note: The ncfnbcs process uses unified logging: You do not have to manually create a log directory for ncfnbcs. More information on unified logging is available in the NetBackup Logging Reference Guide.
Enter the following on the backup host:
Windows:
Create the DWORD registry entry VDDK_VERBOSE in the following location:
HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion > Config
Linux:
Add the following to the
/usr/openv/netbackup/bp.conffile:VDDK_VERBOSE=numeric value
- Set the numeric value of VDDK_VERBOSE as follows:
0
Panic (failure messages only).
1
Level 0 + error logging.
2
Level 1 + warning messages.
3
Level 2 + audit messages.
4
Level 3 + informational messages.
5
Highly verbose; level 4 + additional details.
6
Most verbose; level 5 + debug messages.
