Pairing vSphere Replication appliances might result in a 404 error message.

Problem

vSphere Replication might fail with a 404 error when you are pairing vSphere Replication appliances.

This problem happens if you paired the Site Recovery Manager Server instances by using a vCenter Server address that differs from the address in the vCenter Server Address entry in the vSphere Replication virtual appliance management interface (VAMI).

Cause

By default, vSphere Replication uses the IP address of the vCenter Server instance to connect to vCenter Server.

If you paired the Site Recovery Manager sites using host names, the vSphere Replication pairing fails with an error.

Unexpected status code: 404

The vCenter Server address value in the VAMI must match the address that you provide when you connect the sites.

  • If you used an IP address to pair the Site Recovery Manager sites, you must use the same IP address to connect vSphere Replication to vCenter Server.

  • If you used a host name to pair the Site Recovery Manager sites, you must use the same host name to connect vSphere Replication to vCenter Server.

Solution

  1. Connect to the VAMI of the vSphere Replication appliance in a Web browser.

    The URL for the VAMI is https://vr-appliance-address:5480.

    You can also access the VAMI by clicking Configure VR Appliance in the Summary tab in the vSphere Replication view of the Site Recovery Manager interface.

  2. Type the same IP address or host name for vCenter Server as you used when you configured the pairing of the Site Recovery Manager sites.
  3. Click Save and Restart Service to apply the changes.
