vsphere 5.x unable to re-add the physical RDM

Issue : msa storage had a disk failure and due to the that the VMware had some downtime.
After replacing the faulty disk with a new disk in the storage and physical lun cant be added to the vm as a physical RDM since it throws the error “a general system error occurred disk device path not specified for rdm backing”.
When tried to add the lun as RDM and chose a different datastore for storing the pointer file another error came out stating “add rdm cannot complete the operation due to an incorrect request to the server”

Resolution: A typical vcenter server issue where you will face problems in adding luns to hosts. connected directly to the host and tried adding it as a physical RDM again and it worked.
Issue resolved.
