FC Configuration

Shown below is a typical FC configuration with Everpure FlashArray.

1. Determine the WWPN of the servers, issue the following command on the hosts: systool –c fc_host –v | grep port_name.
   Use the WWPN to do the zoning on the SAN switch and create the Pure Storage side host group and host configuration (populate the WWPNs on the Pure Storage GUI).
2. We recommend that you update your multipath.conf file with the settings above in Multipath Configuration. To verify the status, run multipath –ll or multipath status
3. Now enable the multipathing on the server, hop onto your XenCenter, and put the server in Maintenance Mode. Select the server’s properties tab and then select multipathing from the left panel, enable multipathing. Exit from Maintenance Mode, you are all set. The following steps describe in detail how to configure multipathing in XenCenter.
   • Open XenCenter and right-click on the XenServer Host, select Enter Maintenance Mode from the drop-down menu. It will ask you if you want to move the VMs to another host.
     
     
     
     Select Enter Maintenance Mode on the pop-up window.
   • Now the server is in Maintenance Mode.
     
     
   • Select properties and enable Multipathing as shown below.
     
     
   • Exit Maintenance Mode and reboot the server to make the configuration stick.
     
     
4. Repeat these steps for all of the servers in the cluster pool. Note, this can be accomplished by commands like xe CLI commands.
