BTAFM5002E The SMI agents SMIURL returned an error or can no longer contact the switches.
Explanation
When a fabric uses a data source from an SMI agent, the fabric probe uses the data source to try to rediscover the fabrics and switches. A problem was encountered during this step. The SMI agents either returned an error, or the SMI agents can no longer contact the switches.
Action
Check that the SMI agent service is running. Check the SMI agent logs and UI for problems, for example, problems with contacting the switches. Check for any general problems on the SMI agent system. For example, check the memory available on the system, and check that the disk drive space is sufficient. If you cannot resolve the problem, contact IBM Software Support.
