Stand by power supply replacement. VPlex Solve procedure for the replacement of an engine Stand by power supply (SPS) fails reporting: Could not obtain the original status for unit engine-X-X|stand-by-power-supply-X. This indicates that the unit is unreachable or unhealthy. Example: Replacement of Engine-2-2 stand-by-power-supply-b which is confirmed to be faulted. As per the Solve procedure: hardware component to replace Power supplies and modules, Power Modules: SPS module for GeoSynchrony release:: 5.1, 5.2, 5.3, 5.4, 5.5, 6.0 task 5 Disabling SPS Conditioning steps 1-3 looks as follows: VPlexcli:/> ll engines/engine-2-2/stand-by-power-supplies/*/conditioning/engines/engine-2-2/stand-by-power-supplies/stand-by-power-supply-a/conditioning: Name Value ---------------------- ---------------------------- enabled true in-progress false manual-cycle-requested false next-cycle Mon May 14 00:00:00 UTC 2018 previous-cycle Mon Apr 09 00:00:01 UTC 2018 previous-cycle-result PASS/engines/engine-2-2/stand-by-power-supplies/stand-by-power-supply-b/conditioning: Name Value ---------------------- ----- enabled - in-progress - manual-cycle-requested - next-cycle - previous-cycle - previous-cycle-result -VPlexcli:/> battery-conditioning disable -s /engines/engine-2-2/stand-by-power-supplies/* battery-conditioning disable: Evaluation of <<battery-conditioning disable -s /engines/engine-2-2/stand-by-power-supplies/*>> failed. cause: Command execution failed. cause: Failed to disable conditioning on backup battery units 'engine-2-2|stand-by-power-supply-a, engine-2-2|stand-by-power-supply-b'. cause: Could not obtain the original status for unit engine-2-2|stand-by-power-supply-b. This indicates that the unit is unreachable or unhealthy.
The Battery-conditioning disable command as per the procedure task 5 step 3 is attempting to disable conditioning on SPS A and B in the engine. Here the problem SPS B is failed to the point that it is not responding to the commands issued. VPlexcli:/> ll engines/engine-2-2/stand-by-power-supplies/*/conditioning Where no Values are provided: /engines/engine-2-2/stand-by-power-supplies/stand-by-power-supply-b/conditioning:Name Value ---------------------- ----- enabled - in-progress - manual-cycle-requested - next-cycle - previous-cycle - previous-cycle-result - Disable command. battery-conditioning disable -s /engines/engine-2-2/stand-by-power-supplies/* When using "/stand-by-power-supplies/*," it applied to both SPS A and B simultaneously and because the problem SPS B is failed to the point it is non-responsive the CLI command fails reporting: battery-conditioning disable: Evaluation of <<battery-conditioning disable -s /engines/engine-2-2/stand-by-power-supplies/*>> failed. cause: Command execution failed. cause: Failed to disable conditioning on backup battery units ' engine-2-2|stand-by-power-supply-a , engine-2-2|stand-by-power-supply-b'. cause: Could not obtain the original status for unit engine-2-2|stand-by-power-supply-b . This indicates that the unit is unreachable or unhealthy.
Workaround to replace solve procedure task 5 step 3. As per the procedure: Check if SPS conditioning is enabled on either SPS module, by issuing the following command: ll /engines/ engine-id /stand-by-power-supplies/*/conditioning As per the procedure: Note the next-cycle value for the SPS modules. Workaround to be applied if you experience the issue documented above: Disable conditioning on the working SPS in the engine [example engine-2-2 stand-by-power-supply-a] VPlexcli:/> battery-conditioning disable -s engines/engine-2-2/stand-by-power-supplies/stand-by-power-supply-a Expected output Battery conditioning disabled on backup battery units 'engine-2-2|stand-by-power-supply-a'. As per the procedure: /engines/engine-2-2/stand-by-power-supplies/stand-by-power-supply-a/conditioning:Name Value ---------------------- ---------------------------- enabled false in-progress false manual-cycle-requested false next-cycle Mon May 14 00:00:00 UTC 2018 previous-cycle Mon Apr 09 00:00:01 UTC 2018 previous-cycle-result PASS/engines/engine-2-2/stand-by-power-supplies/stand-by-power-supply-b/conditioning: Name Value ---------------------- ----- enabled - in-progress - manual-cycle-requested - next-cycle - previous-cycle - previous-cycle-result - Next Steps; Proceed with the remaining replacement steps as per the procedure to complete the faulty SPS replacement.
