This document describes further detail about a cluster error.
Why am I not able to add a third node to a cluster when a trial or other temporary license is in place?
In the attempt to add a third node to a cluster whose server nodes use trial or other temporary Cisco Information Server (CIS) license keys, the browser manager's user interface pops up this error: "The license type is incompatible with the remote servers license type".
By design, when trial or other temporary (expiring) server licenses are used, that restricts the cluster to have only two nodes. The error message is not apparent to the user, but this is a known limitation of the trial license mode.
The solution is to install permanent license keys in order to allow the cluster to use more than two nodes.
