Failover stops with the error, The parameter is incorrect. (87), during storage preparation on some or all LUNs (2018597)
- SRM test and real failovers stop during storage preparation
- You receive this error:
Failed to create snapshots of replica devices for group 'protection-group-999' using array pair 'array-pair-999': Vmacore::SystemException "The parameter is incorrect. " (87)
- The error occurs before the rescan step. However, if you manually rescan your storage from the ESX host you see that the LUN has been created and presented successfully.
All timestamps earlier than January 1 1970 experience this issue.
If you encounter this issue, check with your SRA vendor for a fix. As a workaround you can change the time zone of your storage.
At the time of writing, GMT and UTC are handled correctly, but Central European summer time (CEST) is not.
