Configuring VxMS and vhd logging
The following procedure describes how to configure VxMS logging for NetBackup.
Note:
VxMS logging may require significant resources on the Hyper-V server.
To configure VxMS and vhd logging on the Hyper-V server
- Create the VxMS log directory:
install_path\NetBackup\logs\vxmsNote:For logging to occur, the VxMS folder must exist.
Note:If you have run the NetBackup mklogdir.bat command, the VxMS log directory already exists.
- In the Windows registry, create the DWORD registry entry
VXMS_VERBOSEin the following location:HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion > Config
- To configure the logging level, set the numeric value of
VXMS_VERBOSEto 0 or greater. Larger numbers result in more verbose logs.See Table: VxMS logging levels for the available logging levels.
- To change the log location:
Open regedit and go to the following location:
HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion
Create the registry entry
vxmslogdirwith a string value(REG_SZ). For the string value, specify the full path to an existing folder.
Note:You can use NTFS compression on VxMS log folders to compress the log size. The new logs are written in compressed form only.
Note:If the VxMS log location is changed, the Logging Assistant does not collect the logs.
Table: VxMS logging levels lists the VxMS logging levels.
Note:
Logging levels higher than 5 cannot be set in the Logging Assistant.
Note:
Logging levels higher than 5 should be used in very unusual cases only. At that level, the log files and metadata dumps may place significant demands on disk space and host performance.
Table: VxMS logging levels
Level | Description |
|---|---|
0 | No logging. |
1 | Error logging. |
2 | Level 1 + warning messages. |
3 | Level 2 + informative messages. |
4 | Same as level 3. |
5 | Highly verbose (includes level 1) + auxiliary evidence files (.mmf, .dump, VDDK logs, .xml, .rvpmem). You can set the logging level for the VDDK messages. |
6 | VIX (VMware virtual machine metadata) dumps only. |
7 | VHD (Hyper-V virtual machine metadata) dumps only. |
> 7 | Full verbose + level 5 + level 6 + level 7. |
