ipmilan fence type test fails with error for a RHV host that is CISCO UCS server without the Cisco UCS infrastructure.

Solution In Progress - Updated -

Environment

  • Red Hat Virtualization (RHV-M) 4.4.6

Issue

  • The RHV host is a CISCO UCS series server without the Cisco UCS infrastructure (no org-name configured)

  • RHV host configured to use ipmilan type.

  • The test from the RHV-M GUI/Webadmin fails with the following error:

Test failed: WARNING:root:Parse error: Ignoring option 'agent' because it does not have value WARNING:root:Parse error: Ignoring unknown option 'ssl_insecure=1' ERROR:root:Failed: Unable to obtain correct plug status or plug is not available 
2021-07-21 17:54:27,565 ERROR: Failed: Unable to obtain correct plug status or plug is not available

Resolution

  • The options lanplus=1,privlvl=Operator must be set for the fence type

  • In Edit fence agent window, for example set;

    • Address: XXX.XXX.XXX.XXX
    • User Name: user_name
    • Password: ******
    • Type: ipmilan
    • Options: lanplus=1,privlvl=Operator

Root Cause

  • The cisco_ucs fence type does not support the CISCO UCS server that being used stand-alone (without the UCS infrastructure) and the ipmilan fence type must be used instead.

Diagnostic Steps

  • Error reported in the engine logs from the test.
    When fencing a host, RHV will select a proxy host to fence a host.
    In this case, the host rhv-h1.example.com is the proxy host used to fence rhv-h2.example.com.

  • On rhv-h2.example.com, the fence_ipmilan command can be used to troubleshot the problem.
    In this case, the fence_ipmilan utilizes the /usr/bin/ipmitool command and the -L ADMINISTRATOR is set.
