You might encounter the following issues during installation or operation.
Agent registration
On Windows, if the agent fails to establish a connection with the
PowerProtect Data Manager server, agent registration might fail with the following error message:
During a network connectivity test, the agent is unable to reach the PowerProtect Data Manager server by using ping.
1. If the ping command is blocked in the environment, the agent registration can still complete successfully.
Review the agent service logs at INSTALL_DIR\DPSAPPS\AgentService\logs to verify that the registration is successful. If the registration is successful, the status of the agent host indicates Registered in the PowerProtect Data Manager UI.
2. If the ping command is not blocked in the environment, the agent registration might not complete successfully because a network connection cannot be started. If this occurs, complete the following steps to troubleshoot the issue:
On Linux or AIX, if the agent fails to establish a connection with the
PowerProtect Data Manager server, agent registration might fail with the following error message:
During a network connectivity test, the agent is unable to reach the PowerProtect Data Manager server by using ping and curl.
1. If the ping command is blocked in the environment and curl is not installed, the agent registration can still complete successfully.
Review the agent service logs at /opt/dpsapps/agentsvc/logs to verify that the registration is successful. If the registration is successful, the status of the agent host indicates Registered in the PowerProtect Data Manager UI.
2. If the ping command is not blocked in the environment, the agent registration might not complete successfully because a network connection cannot be started. If this occurs, complete the following steps to troubleshoot the issue:
If agent registration fails with these error messages, complete the following operation:
Use any network packet tracing tool to trace the packets from the agent system to
PowerProtect Data Manager.
Start the packet tracing between the source IP of the agent system and the destination IP of
PowerProtect Data Manager.
Start the network traffic between the agent system and
PowerProtect Data Manager.
Wait 10 to 15 seconds.
Analyze the captured packets.
Look for SYN and SYN_ACK packets to see if a 3-way handshake is being performed.
Determine whether the source agent or the destination
PowerProtect Data Manager is blocking the connection.
If network traffic is blocked, contact your network security team to resolve the port communication issue.
Agent host is registered with short name instead of FQDN
Application agent registration using the short name of the agent host is not supported after updating to
PowerProtect Data Manager 19.11 or later versions.
If the agent host was previously registered with the short name, and you attempt to re-register the host with the short name after updating
PowerProtect Data Manager to version 19.11 or a later version, registration fails with the following error:
Unable to register the agent host <hostName> because short name is not allowed for agent registration.
To resolve the issue, do not remove the host. Configure the host with the Fully Qualified Domain Name (FQDN), and then retry the registration.
If you try to register a new host with the short name after updating
PowerProtect Data Manager to version 19.11 or a later version, registration fails with the following error:
Unable to register the agent host <hostName> because short name is not allowed for agent registration.
To resolve this issue, remove the application agent host in the
PowerProtect Data Manager UI:
Go to
Infrastructure > Application Agents.
Select the entry for the application agent host and click
Remove.
After the removal, the host is in a "Deleted" state.
NOTE: The application agent host is automatically removed from the
Application Agents window within 24 hours after the deletion.
After the removal process is complete, configure the host with the Fully Qualified Domain Name (FQDN), and then retry the registration.
PowerProtect agent service operations
To troubleshoot PowerProtect agent service operations, you can check the PowerProtect agent service log file
OpAgentSvc-<timestamp>.log, which is created in
<agent_service_installation_location>\logs on Windows and
<agent_service_installation_location>/logs on AIX or Linux. To modify the log level and retention of temporary files, you can modify specific parameter settings in the
config.yml file.
To modify the log level and retention of temporary files, you can perform the following steps:
Stop the agent service.
Open the
config.yml file in an editor.
Modify the log-level settings in the following parameters, as required:
DEBUG
INFO
WARNING
ERROR
CRITICAL
NOTE: These parameters are listed in order of decreasing number of messages in the debug information output. The default log-level is
INFO.
To retain the temporary files, set the
keepTempFiles parameter to True in the
config.yml file.
NOTE: The agent service and application agent communicate through the temporary files, which are typically deleted after use but can be useful for troubleshooting purposes. Do not leave the
keepTempFiles parameter set to True permanently, or the temporary files can use excessive space on the file system.
Start the agent service.
PowerProtect Data Manager UI display of localhost.localdomain hostname
In the
PowerProtect Data Manager UI, the
Application Agents,
Asset Sources, and
Protection Jobs windows might list the asset primary hostname as localhost.localdomain instead of the expected FQDN.
The display of localhost.localdomain as the hostname in the
PowerProtect Data Manager UI windows might occur when you specify the host's actual FQDN setting for the loopback address in the
/etc/hosts file. For example, when you add the following settings in the
/etc/hosts file, the first setting value, localhost.localdomain, appears as the hostname in the
PowerProtect Data Manager UI windows, instead of the actual FQDN:
Ensure that the host's actual FQDN is not specified for the loopback address and do not specify hostnames that start with "local" in the
/etc/hosts file.
PowerProtect agent service installation failures
A PowerProtect agent service installation might fail with the following error message:
Service 'PowerProtect Agent Service' (AgentService) could not be installed. Verify that you have sufficient privileges to install system services.
Possible causes of the installation failure are as follows:
The installation was attempted on a passive node of a Failover Cluster Instance (FCI).
The installation was canceled and a rollback left some stale entries of PowerProtect agent services.
As a workaround, clean up the PowerProtect agent service entries, and retry the installation.
Failure of PowerProtect agent service to start on Windows
After the application agent is installed, the PowerProtect agent service might fail to start on the Windows operating system.
Check for the following timeout error messages in the event viewer logs:
A timeout was reached (30000 milliseconds) while waiting for the PowerProtect Agent Service service to connect.
The PowerProtect Agent Service service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion.
Asset discovery failure causes databases to not appear in
PowerProtect Data Manager UI
Asset discovery by
PowerProtect Data Manager might fail with the following error message, which causes the Microsoft SQL Server databases to not appear in the
PowerProtect Data Manager UI:
agent-id is missing in the Agentsvc logs
As a workaround, confirm whether the
agent-id.yml file exists under the
\DPSAPPS\AgentService\ directory and then perform the appropriate action:
If the
agent-id.yml file does not exist under the
\DPSAPPS\AgentService\ directory, run the Microsoft application agent installation with the
Change option and then run a discovery operation.
If the
agent-id.yml file exists under the
\DPSAPPS\AgentService\ directory, run a manual discovery operation on the Microsoft SQL Server hosts. Then if the databases still do not appear in the
PowerProtect Data Manager UI:
Delete the existing
agent-id.yml file.
Run the Microsoft application agent installation with the
Change option.
Run a discovery operation on the Microsoft SQL Server hosts.
Asset discovery failure in an FCI environment
If reverse DNS lookup is not configured for the Microsoft SQL Server virtual server name used in a Failover Cluster Instance (FCI), asset discovery can fail and leave the assets unprotected.
As a workaround, configure the reverse DNS lookups for the Microsoft SQL Server virtual server names used in all Failover Cluster Instances.
Error during configuration of Microsoft SQL Server application-aware protection
When you configure the support for Microsoft SQL Server application-aware protection, the configuration job might fail with the following error message:
Unable to register PowerProtect Agent Service. SSL certificates are not present.
After this error message is displayed, restart the configuration job.
Deletion compliance for SLA validation job marked as "Failed" in
PowerProtect Data Manager UI
Due to a cancel request and create-new-copy deletion request occurring simultaneously, deletion compliance for an SLA validation job is incorrectly shown as "Failed" in the UI, even though the copy deletion has succeeded. This issue can occur if replication copies exist, but the corresponding backup copy has been deleted. In this case, the retention time of the replication copies is greater than the retention time of the backup copy. Once the replication copies expire or are manually deleted, it triggers the catalog deletion request, which marks the copy as "Deleted."
Deletion compliance for SLA validation job marked as "Failed" due to copy deletion delay
When the deletion of backup copies is delayed, the deletion compliance for an SLA validation job might be shown as "Failed" in the
PowerProtect Data Manager UI. The following error message also appears:
One or more copies have exceeded their Retention Window.
This issue can occur when the deletion of specific backup copies is delayed due to a large number of backup copies being deleted at the same time. As a result, when the compliance check job runs at a preset time, the specific backup copies are not yet deleted. You can ignore the error message, and confirm at a later time that the specific backup copies have been deleted.
Issue with trailing spaces in Microsoft SQL Server database names
Due to a VSS limitation, you cannot use trailing spaces within the names of Microsoft SQL Server databases protected by an application-consistent data protection policy.
Incorrect database size in
PowerProtect Data Manager UI
If a file stream Microsoft SQL Server database is offline, the database size might be displayed incorrectly in the
PowerProtect Data Manager UI.
The incorrect database size is displayed when you go to
Infrastructure > Assets in the
PowerProtect Data Manager UI and select the
SQL tab.
If the database comes online later, the database size is displayed correctly after the next assets discovery operation.
Uninstallation issue in a UAC enabled environment
In a UAC enabled environment, an issue occurs when a domain user or local user that is added in the "Administrators" Active Directory group performs a manual uninstallation of the VM Direct agent. The
User Account Control window appears with the following prompt about the
XXXXXX.msi program:
Do you want to allow the following program to update software on this computer?
This prompt message can be ignored.
Exit of agent service
register.bat with error code 2
When you try to add a host to an existing virtual machine application-aware protection policy, the agent service
register.bat script might exit with error code 2:
Unable to register PowerProtect Agent Service. Registration script returned with exit code 2.
To resolve this issue, complete the following steps.
Edit the
PowerProtect Data Manager protection policy, and remove the Microsoft SQL Server client.
On the Microsoft SQL Server client, uninstall the Microsoft application agent and vProxy agent:
In the
PowerProtect Data Manager UI, edit the protection policy, add the Microsoft SQL Server client to the policy, and wait for the configuration job to finish.
Confirm that the PowerProtect agent service is running on the Microsoft SQL Server client. Check the PowerProtect agent service status from the Services Manager.
VM Direct support issue with an AAG cluster in an IPv6 environment
In an IPv6 environment, registration with
PowerProtect Data Manager might fail for a node in a clustered Always On availability group (AAG) that is configured for VM Direct operations. The following error message might be displayed:
Unable to register PowerProtect Agent Service. Registration script returned with exit code 13.
In an IPv6 environment with VMware Tools version pre-12.0.5, Microsoft SQL Server VM Direct operations are not supported for an AAG cluster that is configured with file share witness in
PowerProtect Data Manager.
As a workaround, upgrade the VMware Tools to version 12.0.5 or later and then register the clustered AAG node with
PowerProtect Data Manager.
Multiple virtual networks (MVLANs) for Microsoft SQL Server application-aware protection
PowerProtect Data Manager cannot automatically configure a virtual network connection between an agent in a virtual machine and
PowerProtect Data Manager when
PowerProtect Data Manager is configured with multiple virtual network connections.
If you use multiple virtual networks, the virtual machine asset must have a connection to the default interface for
PowerProtect Data Manager. Manually configure the VLAN to provide access to the virtual machine before you add the virtual machine to the protection policy.
Edit Retention button is disabled for asset copies
On the
Infrastructure >
Assets page >
Asset <asset name> page, the
Edit Retention button is disabled.
The
Edit Retention button is enabled only when the copy status of the asset source is
Available. In detail, if deleting a copy of a protected asset fails, the
Copy Status will be updated to another state from
Available, and the
Edit Retention button is disabled.
Workarounds are:
Edit the retention period of an asset copy if its status is
Available.
Do not try deleting an asset copy before its retention period.
Non-English asset names appear as question marks
On an English OS, when you add databases with non-English names as assets in
PowerProtect Data Manager, the asset names appear as question marks (??) in the
PowerProtect Data Manager UI. The asset names appear in the
Infrastructure > Assets > SQL window.
As a workaround, ensure that the OS and the asset names that you create in Microsoft SQL Server are of the same language.
