Array Manager Ping Failed in VMware Live Site Recovery despite successful discoverArray command

Products

• VMware Live Recovery

Issue/Introduction

• In VMware Live Site Recovery (VLSR), pings to the Array Manager fails.
  
  
• Upon reviewing the Storage Replication Adapter (SRA) logs, the discoverArray command (which is executed during the ping operation) appears to complete successfully, as shown in the following log entries:

[YYYYMMDDHHMMSS ######  #### [e-mail]                ] [Commence]: Discovering Arrays
[YYYYMMDDHHMMSS ######  #### [e-mail]                ] [Complete]: Finished discovering Arrays

Environment

VMware Live Site Recovery using Array-Based Replication (ABR)

Cause

This issue occurs when the discoverArray command execution takes longer than the configured SRA command timeout value (default: 300 seconds). Even if the command eventually completes successfully on the SRA side, VLSR times out the operation and reports a ping failure.

This condition is more likely to occur in larger environments with a high number of storage objects.

Resolution

To resolve this issue, increase the storage.commandTimeout value in the Advanced Settings of VMware Live Site Recovery.

Steps:

1. Log in to the vSphere Client.
2. Navigate to Site Recovery > Open Site Recovery.
3. Select the site pair and click View Details.
4. In the left pane, click Configure > Advanced Settings > Storage.
5. Locate the parameter storage.commandTimeout and increase its value (e.g., from 300 to a higher value).

Note: The optimal timeout value depends on the storage environment. Consult your storage vendor for the recommended value for this parameter.
