VMware just changed their VCB multipathing support. Before the KB article stated “Powerpath and other multipathing software.” The KB article has been changed and contains specific version of Powerpath which are officially supported and the “other multipathing” has been removed. Still I’m no fan of multipathing software on the VCB host, I would prefer using 1 HBA for uploading to a holding tank and 1 HBA for downloading the images from the SAN.
