Troubleshooting the sensor

This topic describes common problems that occur with the EMC ViPR SRM sensor and presents solutions for those problems.

The sensor cannot discover all the Arrays configured in EMC

Problem
The sensor is not able to discover all the arrays, as visible in the EMC ViPR SRM GUI.
Solution
EMC ViPR SRM sensor supports discovery of only VMAX arrays. So only the VMAX arrays configured in EMC will be discovered by EMC ViPR SRM sensor.

The sensor does not discover the host computer systems

Problem
The sensor does not discover the host computer systems.
Solution
The sensor can discover only hosts that have all the parameters configured present against the HOST.api query in emcvipr.config file, present in given below sensor plugin directory:
/dist/osgi/plugins/com.ibm.cdb.discover.sensor.app.srm.emc.vipr_1.0.0
If any of the below parameter is not set in HOST.api, then no hosts will be returned in the REST API response and therefore, no hosts will be discovered. 
HOST.name=HOST
HOST.api=fields=devtype,device,ip,vendor,hostname,model,osarch,virtual,fqdn,devdesc\        
&filter=devtype%3D%27Host%27

The sensor does not populate the capacities

Problem
The sensor does not populate the capacities for Storage Subsystem(Arrays), Volumes or Pools.
Solution
Capacities might not be populated for StorageSubsystems(Arrays), if the value or number of days set for the property “com.ibm.cdg.discover.sensor.app.srm.emc.vipr.conn.period.days” is not set as per the last scan done or last report generated in EMC.
Also, it could be possible that, capacities are discovered only for some volumes, arrays or pools, this could be due to the results getting trimmed in the query result. By default, SRM will trim the REST API response till 500 entries. You can increase the limit of records by increasing the value corresponding to the property “com.ibm.cdg.discover.sensor.app.srm.emc.vipr.conn.limit” present in emcvipr.properties file, present in given below sensor plugin directory:
/dist/osgi/plugins/com.ibm.cdb.discover.sensor.app.srm.emc.vipr_1.0.0
