Tips and Tricks

MultiPathMultiPathTips and Tricks

� General Recommendations for MultiPath� General Recommendations for MultiPath� IPv4 should be selected (IPv6 not supported)

� Do not establish multiple connections to one target before MultiPath installation

� For iSCSI boot "spanning tree" must be disabled at the boot NIC's switch port� For iSCSI boot "spanning tree" must be disabled at the boot NIC's switch port

� Check presence and status of all MultiPath Groups� MultiPath status must show Active / Standby� MultiPath status must show Active / Standby� Check Acknowledge Configuration to enable the monitoring of missing paths
