Error description
Storage Insights probes for DS8000 devices collect microcode information from the DS8000 device. When the DS8000 device provides an empty microcode version, the probe fails and logs the following: Probe failure messaging is as follows: Error HWNEP0129E The operation failed because the device returned unexpected values. Error HWNEP0134E Following exception occurred: com.ibm.tpc.ep.base.EPHdlrRunException: Retrieved empty MicrocodeLevel for lpars. Error HWNEP0135E External process failed with error code -101. Error HWN021503E The action cannot be completed Information HWN021709I Collection for storage system DS8000-2107-75XXXXX-IBM completed. Error BTADS0102E The probe with the run ID 68332 completed with errors. The LPARs not reporting microcode numbers to Storage Insights are: [EP-SubJob: DS8000-2107-xxxxxxx-IBM-8124] [EP_DS_CLI_Probe.getStorageServers] [ERROR] Retrieved empty MicrocodeLevel for lpar: SF75KXXXXXXXX [EP-SubJob: DS8000-2107-xxxxxxx-IBM-8124] [EP_DS_CLI_Probe.getStorageServers] [ERROR] Retrieved empty MicrocodeLevel for lpar: SF75KXXXXXXXX This happens when the DS8K has a CEC that is down. A CEC being down should not cause a probe to fail, nor should missing microcode level information. DS8K support and development are aware of the issue; possible change to DS8K behavior in this situation is also being analyzed. This APAR addresses the IBM Storage Insights behavior in response to this DS8K condition. ________ ____________________________________________ The defect is against component: Storage Insights Server/Manager build/release (TPC): 5.3.7 Problem as described by customer: Degraded monitoring status for DS8K systems; Initial customer impact (low/med/high): low
