Using Site Recovery Manager 5.8 and linked mode? Update to SRM 5.8.1 or you are not able to recover!

When you deployed Single Sign On (SSO) in vSphere 5.5 in multi-site configuration (to be able to use linked mode) you are not able to recover your virtual machines using VMware Site Recovery Manager 5.8 when the protected site is not available.

This is a serious bug which appears to be unknown to many SRM customers. Many customers test SRM without disabling the connection to the SSO instance running in the protected site.

While SSO runs in the recovery site deployed as multi-site, this SSO instance is basically for caching, not for high availability.

When performing a recovery when the connection to the protected site is lost, you will not see recovery plans. Errors displayed in the vSphere web client are:

Failed to connect Site Recovery Manager Server(s).
Cause:
Failed to retrieve pairs from Site Recovery Manager Server at https://<vc hostname>:8095/dr.

Solution: 

This is a known issue. Upgrade to Site Recovery Manager 5.8.1 as described in the VMware KB article..

See the 5.8.1 release notes.

Performing a recovery reports the error: Failed to connect Site Recovery Manager Server(s).

If the vCenter Server instances on the protected site and recovery site are configured in Linked Mode and the protected site is offline or the vSphere Web Client server is unable to communicate with the vCenter Server Inventory Service on the protected site, you cannot perform a recovery using the vSphere Web Client because there are no Recovery Plans visible in the user interface. Recovery fails with the error Failed to connect Site Recovery Manager Server(s). Cause: Failed to retrieve pairs from Site Recovery Manager Server at https://vcenter_server_hostname:8095/dr. This has been fixed and resolves the issue described in KB 2093902.
