Troubleshooting

The following pages present typical problems and solutions as well as suggested testing methods.

Checking logs

Checking event logs is often the first step when trying to identify problems.

Error messages in the logs may indicate the problem.

Check application event logs associated with Exchange, FRS, and HP VSS Hardware Provider.

Check Windows system event logs.

Common problems and solutions are also listed below.

Troubleshooting checks

The following checks may help you isolate and resolve issues with FRS or associated systems and software.

1.Ensure the HP Business Copy license and the HP VSS Hardware Provider were installed and correctly configured.

A simple way to verify the HP VSS HWP is installed correctly, is to see if it is running. At the command line, enter:

vssadmin list providers

Look for the HP VSS HWP in the resulting list.

2.In order for the production and recovery servers and their applications to communicate, the Windows DCOM distributed communication process must be able to communicate among all FRS servers. This requires that you be logged into all FRS-related applications and all FRS servers (including Command View) as an administrator and requires connectivity without a firewall between servers. You can check for DCOM errors in the system event logs.

3.Check that the Exchange server is online.
