      Description

      NOTE: vesrion is 7.1 LTSR CU1

      We have a four host xenserver pool connected to two equallogic SAN, each one with two configured iscsi management interfaces. We follow set up procedure as described in https://support.citrix.com/article/CTX138429; we set up two iface tied to each iscsi management iscsi interface, and we get two connections for each host with each SAN as expected. But, after rebooting a host, iscid seems not to use new defined ifaces and only use default one; as a result, there is only one session for SAN.

      The procedure works fine in a standalone CentOS 7 server, but for some reason, with Xenservers 7.1 CU hosts don't, because after rebooting such hosts, iscsid seems not to use the two iface created. It uses only the default iface. This behavior is shown with these commands:

      1 -Just after reboot:

      iscsiadm -m iface -P 1
      Iface: default

      2- Then I do iscsiadm changes and these are things before reboot:

      3 - Rebooting the server, and we are again in point 1
