CMMVC4043W If you are re-adding this node to the SAN, ensure that you are adding the node to the same I/O Group it was removed from. Failure to do this can result in damaging your data. Use the information that was recorded when the node was originally added to the cluster. If you do not have access to this information, call your support center to add the node back onto the cluster without damaging data. If you are adding the node into the cluster for the first time, please record the node serial number, WWNN, all WWPNs, and the I/O Group to which it has been added.

Explanation

Failure to re-add a node to the same I/O Group it was removed from can result in data damage.

Action

If you are adding the node into the cluster for the first time, please record the node serial number, worldwide node name (WWNN), all worldwide port names (WWPNs), and the I/O Group to which it has been added. This can avoid a possible data damage exposure if the node must be removed from and re-added to the cluster. If you are re-adding this node to the SAN, ensure that you are adding the node to the same I/O Group it was removed from. If you do not have access to this information, call your support center to add the node back onto the cluster without damaging data.
