Abstract: Examples of techniques for failure detection for central electronics complex (CEC) group management are described herein. An aspect includes issuing a first virtual input/output server (VIOS) probe to a hardware management console (HMC) of a central electronics complex (CEC) group. Another aspect includes receiving a first response packet that includes health data corresponding to a plurality of VIOSes. Another aspect includes determining, based on the first response packet, that cluster down is indicated on a first VIOS. Another aspect includes, based on determining that cluster down is indicated on the first VIOS, getting a VIOS state for the first VIOS from the HMC. Another aspect includes determining based on the VIOS state that the first VIOS is in a down state and determining that the first VIOS is unhealthy. Another aspect includes updating a health data entry corresponding to the first VIOS to indicate that the first VIOS is unhealthy.

Abstract: Examples of techniques for failure detection for central electronics complex (CEC) group management are described herein. An aspect includes issuing a first logical partition (LPAR) probe to a hardware management console (HMC) of a central electronics complex (CEC) group, wherein the CEC group comprises a plurality of LPARs. Another aspect includes receiving a first response packet from the HMC corresponding to the first LPAR probe, wherein the first response packet comprises health data corresponding to a first LPAR of the plurality of LPARs. Another aspect includes storing the health data corresponding to the first LPAR in a first health data entry corresponding to the first LPAR. Another aspect includes, for a second LPAR of the plurality of LPARs that was not included in the first response packet, updating a second health data entry corresponding to the second LPAR to indicate that the second LPAR is healthy.
