SRA command 'discoverArrays' fails with empty response during array pairing in VMware Live Site Recovery

Products

• VMware Live Recovery

Issue/Introduction

Symptoms:

When attempting to configure Array Managers or add an Array Pair in the VMware Live Site Recovery (LSR) user interface, the task fails with the following error: SRA command 'discoverArrays' didn't return a response

Using vSphere Replication with array based replication.

Environment

VMware Live Site Recovery 9.x

Cause

The VMware Live Site Recovery software queries the storage array for a list of active replication connections via the discoverArrays command. If the storage array has no active replication sessions established or is unable to fetch details from the backend, it returns an empty XML list.

Review the SRA logs located at /var/log/vmware/srm/SRAs/ on the LSR appliance. You may observe the following XML validation error indicating an incomplete response:

Resolution

To resolve this issue, ensure that the backend storage replication is correctly configured and active before attempting to pair the arrays.

Engage the storage vendor (e.g., Dell EMC) to confirm that the two backend storage arrays have established a valid replication connection.

Once the connectivity is fixed, the array pair will be successful.
