Troubleshooting and Miscellaneous Issues

This section contains common troubleshooting information and describes miscellaneous issues that might occur during

your installation.

Rescan During Failover Not Detecting Virtual Disk Mappings

Depending on the type of Fibre Channel cards and iSCSI configuration used in the ESX hosts, you might encounter errors

during the test failover stating that the datastore volumes cannot be located. If issuing a rescan all command from the

Storage Adapters view under the Configuration tab for the ESX host does detect the virtual disk mappings, modify the C:

\Program Files (x86)\VMware\VMware vCenter Site Recovery Manager\config\vmware-dr.xml file to execute two

rescans every time the recovery plan is executed by adding <hostRescanRepeatCnt>2</

hostRescanRepeatCnt>

within the <SanProvider> section.

Removing The Snap-XXX- Prefix On Failed-Over Datastores

To restore the name of the datastores to their original name after a failover, modify the vmware-dr.xml file by locating

<fixRecoveredDatastoreNames>false</fixRecoveredDatastoreNames> and by changing false to

true.

NOTE: When changing XML configuration files, always remember to save the file before exiting.

Debugging SRA Errors

If you encounter an error indicating a problem with the SRA, review the latest vmware-dr-x.log file for indications of the

error condition. These logs are located under C:\ProgramData\VMware\VMware vCenter Site Recovery Manager\Logs.

Errors registered from the SRA have an [#x] (x denoting a number) at the beginning of the line.
