Assign the old drive letter to the LUN to which you copied the data. On a Linux host: a. Unmount the original file system on the device. b. - Dell VNXe2 | Configuring Hosts to Access Fibre Channel FC or iSCSI Storage - Page 86

Setting Up MPIO for a Windows Cluster Using a VNXe System Setting up cluster nodes (hosts) For simplicity, this section shows only the setup for the single target vnxeiscsia. Task 1: Configure the iSCSI initiator with MPIO on each cluster node. On each node in the cluster (exhost1 and exhost2): 1. - Dell VNXe2 | Configuring Hosts to Access Fibre Channel FC or iSCSI Storage - Page 91
in the cluster (exhost1 and exhost2): 1. Click Start and enter MPIO to launch the control panel applet. 2. Click the Discover Multi-Path tab, select Add support for iSCSI devices, and click Add. 3. Reboot the node when prompted to do so. Task 3: Verify the MPIO settings on each cluster node. On - Dell VNXe2 | Configuring Hosts to Access Fibre Channel FC or iSCSI Storage - Page 92
