What does this mean? - RESTful error during POST on a ProLiant DL380 Gen9

[AndyChips]

I'm getting the following error after a restart on my ProLiant DL380 Gen9:

Health Status: Configuration Required

- 335-HP RESTful API Error - RESTful API PUT request failed (HTTP Status Code = 405).

BIOS configuration resources may not be up-to-date.

Action: Restore Manufacturing Defaults in RBSU.

What does this mean?

And yes, I've performed a 'Restore manufacturing defaults'  -  no change.

Try updating the system ROM and the iLO firmware

One last suggestion would be to reset the system using mainainance switch 6.  If this doesn't correct the error you need to open a support call with HPE.

power off, switch 6 on, power system on, system will POST and display a message system has been reset. power off, switch 6 off position.

Hi Jimmy. I performed the steps you mentioned but still get the same error, so I'll log a ticket.

Many thanks for your help.

Andy.

Hi Jimmy,

I contacted HPE Support and they sent me instructions on a workaround:

Please Refer to Page 40 : (Heading : 9 Troubleshooting)  : http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=c04423967

I opted for solution 4 as it was far easier than the others:

Procedure 4 Resolution 4: Resetting the HP RESTful API using the iLO SSH CLI

1. Open an SSH connection with iLO, log in using an account with administrator privileges.
2. At the CLI prompt, execute the command oemhp_clearRESTAPIstate. Note that this command might take a few seconds to complete.
3. Restart the server.

I did this and the POST error has now gone.

Thanks for the update, I wasn't aware of that command. I wonder if removing power from the system, or resetting iLO through the web interface would also clear this error

[AndyChips]

Believe me, I lost count of the number of times I removed the power! And yes, I did try the iLO reset too. At least it's all working now. I thought it was going to be a motherboard job.

Had to update to both iLO4 2.50 and v2.30 of System ROM (9/13/2016) on my DL380Gen9 server to be able to successfully clear the POST Message#335 RESTful API Error using the iLO SSH CLI method shown here.
