      Hi, when I map Dell storage volumes in XCP-ng, I get "Virtual Disk Not On Preferred Path" error in Dell management software.

      In the link below I posted in the Dell community and from the answer given I understood that it could be some configuration that I didn't do in XCP-ng. But what would it be?

      https://www.dell.com/community/en/conversations/powermax/virtual-disk-not-on-preferred-path-message-on-powervault-storages/67afaa9c86c8e6496312842f

      Volumes mapped to "RAID Controller Module in Slot 0" do not exhibit the issue. However, volumes mapped to "RAID Controller Module in Slot 1" are changed to "RAID Controller Module in Slot 0", which causes the issue.

      Has anyone dealt with this issue?

        The description below appears in the mapped volume in XO:

        I don't know if the image has any relation to the problem.

          The "Multipathing" option was not enabled on the hosts in the pool. So even though there was more than one connection to the Dell Storage, the warning message was displayed. The controller to be used could be 0 or 1. But because "Multipathing" was disabled, the storage automatically switched from 1 to 0 for some mapped volumes because it believed there was only one possible path.

          I consider this issue resolved!
