Reprotect Fails After Restarting vCenter Server

After you restart vCenter Server, when you use vSphere Replication, reprotect operations sometimes fail.

Problem

After you restart vCenter Server, when you use vSphere Replication, reprotect operations fail with the error

Error - Unable to reverse replication for the virtual machine

'virtual_machine'. The session is not authenticated.

Cause

After vCenter Server restarts, it fails to refresh some sessions that Site Recovery Manager uses to

communicate with vSphere Replication and causes reprotect to fail.

Solution

Restart the Site Recovery Manager services on both of the sites.

Rescanning Datastores Fails Because Storage Devices are Not Ready

When you start a test recovery or a recovery, some SRAs send responses to Site Recovery Manager before a

promoted storage device on the recovery site is available to the ESXi hosts. Site Recovery Manager rescans

the storage devices and the rescan fails.

Problem

If storage devices are not fully available yet, ESXi Server does not detect them and Site Recovery Manager

does not find the replicated devices when it rescans. This can cause several problems.

Datastores are not created and recovered virtual machines cannot be found.

ESXi hosts become unresponsive to vCenter Server heartbeat and disconnect from vCenter Server. If

this happens,vCenter Server sends an error to Site Recovery Manager and a test recovery or real

recovery fails.

The ESXi host is available, but rescanning and disk resignaturing exceed the Site Recovery Manager or

vCenter Server timeouts, resulting in a Site Recovery Manager error.

Cause

The storage devices are not ready when Site Recovery Manager starts the rescan.
