Symptoms

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-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.

 

Cause

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.

 

Resolution

Workaround to replace solve procedure task 5 step 3.

  1. 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

  2. As per the procedure: Note the next-cycle value for the SPS modules.

  3. 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'.

  4. 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.
