Rescanning Datastores Fails Because Storage Devices are Not Ready

When you start a test recovery or a recovery, some SRAs send responses to VMware Live Site Recovery before a promoted storage device on the recovery site is available to the ESXi hosts. VMware Live Site Recovery rescans the storage devices and the rescan fails.

Problem

If storage devices are not fully available yet, ESXi Server does not detect them and VMware Live Site Recovery 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 VMware Live Site Recovery and a test recovery or real recovery fails.
• The ESXi host is available, but rescanning and disk resignaturing exceed the VMware Live Site Recovery or vCenter Server timeouts, resulting in a VMware Live Site Recovery error.

Cause

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

Solution

To delay the start of storage rescans until the storage devices are available on the ESXi hosts, increase the storageProvider.hostRescanDelaySec setting to a value between 20 and 180 seconds. See Change Storage Provider Settings.
