4. Enter another port (repeating step 3) for those storage devices that support active/activemulti-pathing. This could be the WWPN that is zoned to the XIV on a separate fabric.5. Connect the XIV and non-XIV storage ports that are zoned to one another. This is done byclicking and dragging from port 4 on the XIV to the port (WWPN) on the non-XIV storagedevice to where the XIV is zoned. In Figure 7-6 the mouse started at module 9 port 4 andhas nearly reached the target port. The connection is currently colored blue and turns redwhen the mouse connects to port 1 on the target.Figure 7-6 Dragging a connection between XIV and migration target194 IBM XIV Storage System: Copy Services and Migration
In Figure 7-7 the connection from module 9 port 4 to port 1 on the non-XIV storage device iscurrently active, as noted by the green color of the connecting line. This means that thenon-XIV storage system and XIV are connected and communicating (indicating that SANzoning was done correctly. The correct XIV initiator port was selected. The correct targetWWPN was entered and selected, and LUN 0 was detected on the target device). If there isan issue with the path, the connection line is red.Figure 7-7 Non-XIV storage device definedTip: Depending on the storage controller, ensuring that LUN0 is visible on the non-XIVstorage device down the controller path that you are defining helps ensure properconnectivity between the non-XIV storage device and the XIV. Connections from XIV toDS4000 or EMC DMX or Hitachi HDS devices require a real disk device to be mapped asLUN0. However, the IBM ESS 800, for instance, does not need a LUN to be allocated tothe XIV for the connection to become active (turn green in the GUI). The same is true forEMC CLARiiON.7.3.2 Define the host being migrated to the XIVPrior to performing data migrations and allocating the volumes to the hosts, the host must bedefined on the XIV. Volumes are then mapped to the hosts or clusters. If the host is to be amember of a cluster, then the cluster must be defined first. However, a host can be movedeasily from or added to a cluster at any time. This also requires that the host be zoned to yourXIV target ports via the SAN fabric.1. To define a cluster (optional):a. In the XIV GUI go to the floating menu Host and Clusters Host and Clusters.b. Choose Add Cluster from the top menu bar.Chapter 7. Data migration 195
