Openhpi reports Server in slot # is removed / added during OA switchover

[openhpi2]

During OA switchover for some of the blades (already present in the enclosure) ‘Server in slot # is removed/ added’ is getting reported as below: Snippet of /var/log/messages oa_soap_re_discover.c:164: Re-discovery started Oct 8 06:29:08 localhost openhpid: oa_soap: oa_soap_re_discover.c:848: Server in slot 16 is removed Oct 8 06:29:10 localhost openhpid: oa_soap: oa_soap_re_discover.c:865: Server in slot 16 is added Oct 8 06:29:23 localhost openhpid: ssl: oh_ssl.c:531: Socket connect failed with error: Connection refused Oct 8 06:29:23 localhost openhpid: oa_soap: oa_soap_callsupport.c:652: oh_ssl_connect() failed Oct 8 06:29:23 localhost openhpid: oa_soap: oa_soap_callsupport.c:1098: failed to communicate with OA during soap_call() Oct 8 06:29:51 localhost openhpid: oa_soap: oa_soap_re_discover.c:253: Re-discovery completed

With further analysis found that during switchover getBladeInfoArrayResponse has partNumber and serialNumber as [Unknown] for some of the blades. When these fields are absent in the response structure we go ahead remove and add that particular blade. As OA response does not have data for these fields we are getting these messages during OA switchover. We need to modify our logic in code to take care of this scenario.

OA xml response during switchover having partNumber and serialNumber as [Unknown] for that particular blade are as below:

There is a situation where a blade with normal serial number could be replaced with a blade with unknown or wrong serial number. So it is better to replace the blade during re-discovery if the blade comes out as unknown even if the blade that is already there has a proper serial number. In our testing we found that if we do not replace, we could end up with two blades with same serial number, if we swap two blades during a switch over (one good and one bad). We could make a code change where we could give a message to user if an improper serial number (non-alphanumeric) is present.

• summary: Openhpi reports Server in slot # is removed/ added during OA switchover --> Openhpi reports Server in slot # is removed / added during OA switchover Single quotes removed before Server and after added as xmlfile.write is unable to parse it We need to avoid the quotes and double quotes as they are used in the formatting.
