A number of restrictions exist when you use ESXi with an iSCSI SAN.

  • ESXi does not support iSCSI-connected tape devices.

  • You cannot use virtual-machine multipathing software to perform I/O load balancing to a single physical LUN.

  • ESXi does not support multipathing when you combine independent hardware adapters with either software or dependent hardware adapters.

  • ESXi does not support IPv6 with software iSCSI and dependent hardware iSCSI.
