Symptoms

Test 'dcism' is a health-check that runs on each VxRail node as part of the VxRail health-checks or How to run the VxVerify tool. This check attempts to validate the status of the Dell iDRAC Service Module (iSM), watchdog service, which VxRail ESXi nodes use. Test ResultResult codeResult InterpretationPass0Dc-iSM Dell-iSM watchdog is running normallyWarning1Dc-iSM Dell-iSM watchdog returns an unknown response.Failure2Dc-iSM Dell-iSM returns a status that the watchdog is not running.Critical3This test has no critical result. Each test that passes is not listed in the summary report, for ease of reading. An example of the health-check output is shown below: #========================#======#=========#====================================================================#==============# | Hostname / Category |Status Dell_KB | Warnings or Failures, unless tests Passed ; Product S.N. | #========================#======#=========#====================================================================#==============# | node03 | Failure 193300 | dcism: iSM is not running .|

Cause

If the hostd is stopped or restarted, then the iSM may not come back into a running state, despite being listed as active.The commands are: On ESXi 7.0: /etc/init.d/dcism-netmon-watchdog status iSM is active (not running) On VxRail 8.0: /etc/init.d/dellism status

Resolution

Auto-correction for 'DC iSM not running' If VxRail Manager or VCF Verify report the 'dcism' test failures, then the corrective actions for restarting iSM, the Platform Service, and iDRAC, are done automatically.To run the iSM auto-correction, VxVerify can be run on VxRM as described in the article How to run the VxVerify tool. Manual restart of DCiSM Restart iSM agent with: On ESXi 7.x: /etc/init.d/dcism-netmon-watchdog restart On VxRail 8.x: /etc/init.d/dellism restart After about 2 minutes the iSM should now report as: /etc/init.d/dcism-netmon-watchdog status iSM is active (running) In some VxRail 4.x versions, an alternative response format could be received: iSM is running
