SAN HQ requires all ports on active controller to be up in order to work properly
Thank you for contacting Dell / EqualLogic about this issue.
Yes, you are absolutely correct.
For SanHQ to work properly the host running the SANHQ software must be able to ping each interface on the array. The reason each port on the array needs to be accessible is due to the fact that the array will respond to snmp request on any randomly selected port on the array.
Thus, if one or two network ports on your array goes offline for network related issue, SanHQ may or may not receive SanHQ updates during the expected interval if the problematic network ports are selected.
