VDDK Backup and Restore Jobs Stop Responding

Valid on Windows platforms.

Symptom

VDDK-based backup and restore jobs stop responding.

Solution

VMware VDDK 5.1 contains programmatic problems that can cause VDDK-based backup and restore jobs to stop responding. VMware is aware of the problems encountered and confirmed that they will be fixed in the next release of VDDK. When the next release of VDDK is available, download and install the corresponding version of VDDK into your virtual machine environment.

Until the next release of VDDK is available, complete the following steps to correct this behavior:

1. Log in to the computer where VDDK is installed and open Windows Registry Editor.
2. Locate the following key:

   HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCServe Backup\ClientAgent\Parameters\VDDKTransportLogLevel
   

   Note: Create the DWORD VDDKTransportLogLevel if it does not exist.

3. Set the value of VDDKTransportLogLevel to a value of from 1 though 4.

   Setting a value of 1 though 4 can help to minimize the not responding condition.

4. Resubmit the job.
5. If the job stops responding, set the value of VDDKTransportLogLevel to 1.

   The value 1 disables the SAN/HOTADD and NBDSSL transport modes for VDDK backup and restore jobs.

6. Resubmit the job.
7. If the problem persists, contact Arcserve support for online technical assistance and a complete list of locations, primary service hours, and telephone numbers.
