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.


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.


In Site Recovery Manager 5.1 and earlier, you might have used the storageProvider.hostRescanRepeatCnt parameter to introduce a delay in recoveries. Use the storageProvider.hostRescanDelaySec parameter instead.
