PMP 3.1 license problem

[Ricardo Climent Altable]

A have a problem with two nodes and PMP license.

From the license administrator's windows of PMP I see two nodes like "Unsupported Server". These nodes had a license days ago.

From hpsim menu ---> Deploy ---> License ---> collects Keys the both nodes are seen of the following way:

esmadholdb2 Licensing information error on target system.

esmadholdb1.cesa.red-cesa.es No licensing information found for this system.

it is possible that the PMP database is corrupt?.

The snmp configuration is Ok on both nodes, and other nodes are seen correctly.

Thank in advance.
