In the vSphere Web Client, you can check the status of replication tasks for a vCenter Server. The list of outgoing replications is located on the vSphere Replication tab under Monitoring.

Table 1. Replication States

Status

Description

Possible Cause

Solution

Not Active

The replication is not running at the moment.

  • The source virtual machine is powered off.

  • A communication problem might have occurred between the source ESXi host and the target site.

  • Power on the source virtual machine.

  • If all replications for an ESXi host are in Not Active state, verify that the security rule Replication-to-Cloud Traffic is enabled on the host. This rule opens TCP ports 10000 to 10010 for outgoing communication.

Paused

The replication is not running at the moment.

A vSphere Replication user has paused the replication.

In the list of replications, right-click the paused replication and select Resume.

Error

The replication is not running at the moment.

  • A configuration error occurred.

  • A replication error occurred. For example, the target site infrastructure is not accessible.

  • Try reconfiguring the replication.

  • Navigate to the Issues tab to check if some problem occurred on the virtual machine.

Status (RPO violation)

For replication status OK, Sync, or Full Sync, the replication is running, but the RPO that is set for the replication is not met and is violated.

For replication status Not Active or Error, the replication is not running, and the RPO that is set for the replication is violated.

  • The network connection between the source and the target site is dropping.

  • The bandwidth of the connection between the source and the target site is too low.

  • The replication is not running, so data cannot be replicated on the target site.

  • Improve the network connection between the source and target site.

  • Increase the RPO period.

  • For replication status Not Active or Error, fix the cause for the status and wait for the next sync.
