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.

VxMS and vhd logging on the Hyper-V server

To configure VxMS and vhd logging on the Hyper-V server

  1. Create the VxMS log directory:

    install_path\NetBackup\logs\vxms

    Note: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.

    See NetBackup logs for Hyper-V and how to create them.

  2. In the Windows registry, create the DWORD registry entry VXMS_VERBOSE in the following location:

    HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion > Config

  3. To configure the logging level, set the numeric value of VXMS_VERBOSE to 0 or greater. Larger numbers result in more verbose logs.

    See Table: VxMS logging levels for the available logging levels.

  4. To change the log location:

    • Open regedit and go to the following location:

      HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion

    • Create the registry entry vxmslogdir with 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.

VxMS logging levels

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.
