text: **Prerequisites for Fibre Channel connections**
  The following prerequisites for Fibre Channel connections must be met: 
  
  (cid:2) Cable this system into the SAN of the external storage that you want to migrate. Ensure 
  that your system is cabled into the same storage area network (SAN) as the external 
  storage system that you are migrating. 
  
  If you are using Fibre Channel, connect the Fibre Channel cables to the Fibre Channel 
  ports in*both*canisters of your system, and then to the Fibre Channel network. If you are 
  using Fibre Channel over Ethernet, connect Ethernet cables to the 10 Gbps Ethernet 
  ports. 
  
  (cid:2) Change VMware ESX host settings, or do not run VMware ESX. If you have VMware ESX 
  server hosts, you must change settings on the VMware host so copies of the volumes can 
  be recognized by the system after the migration is completed. To enable volume copies to 
  be recognized by the system for VMware ESX hosts, you must complete one of the 
  following actions: 
  
  – Enable the EnableResignature setting. 
  – Disable the DisallowSnapshotLUN setting. 
  
  To learn more about these settings, see the documentation for the VMware ESX host.
