Error description
Brocade switch probes fail with HWN021899E Switch has not associated fabric. The error is caused by entries in the database associating a particular switch with multiple fabrics due to principal switch changes in the fabric that were not processed correctly. The switch doesn't actually belong to both fabrics at the same time and the incorrect association causes the probe to fail. Principal switch changes can occur with fabrics and should be handled such that Spectrum Control has the correct switch and fabric relationships to continue probing. fabric probe log 2017-09-28 08:24:09.934 BTAFM0614I The probe task is to probe topology and zone. The probe algorithm is CIM association. 2017-09-28 08:24:10.012 BTAFM5003E Requests to an SMI agent did not correctly collect a set of switches for fabric <fabric_WWN>. 2017-09-28 08:24:10.012 BTAFM5002E The SMI agents <agent_IP> returned an error or can no longer contact the switches. 2017-09-28 08:24:12.949 BTADS0102E The data can't be collected by the probe because the data collector or the storage resource that is being probed isn't available.

Problem summary
**************************************************************** * USERS AFFECTED: * * IBM Spectrum Control 5.2.x users monitoring and managing * * Brocade Fabrics. * **************************************************************** * PROBLEM DESCRIPTION: * * Sometimes, when the connection from Spectrum Control Server * * to BNA CIMOM fails and there are multiple CIMOMs used, the * * database data might become inconsistent, regarding Fabric to * * Switch relations. * **************************************************************** * RECOMMENDATION: * * Apply fix maintenance when available * **************************************************************** This fix adds a cleanup procedure that should resolve the issue. This is a 2 step procedure and the cleanup is done when running the Fabric probe the first time, and the Fabric probe will fail. When the Fabric probe is ran the second time it should finish successfully.
