Emc VIPR - Scale IO integration error

Hi,

I am working on EMC Vipr- Scleio integration. I am able to provision / deprovision storage directly from the Scale GUI. However I am only able to provision Datastore once if try from Vipr. Afterwards any provisioning  / de provisioning requests from EMC Vipr results in following Error:

Error 1013: Initiator urn:storageos:Initiator:70ac1d10-ebad-4cea-8c0c-f13cf6b9fbbe:vdc1 in Export Group urn:storageos:ExportGroup:3458c05b-d524-4439-9d9f-ae08772dc917:vdc1 does not have valid host name

Any help would be graetly appreciated.
