<p>I think there might be a bug.. either in the SAP HANA resource or
somewhere, because SUSE Support is still investigating this issue

<pre wrap="">Hi!
I have no specific answer to your question, but since SAP has moved from a command to start the instances to a command that sends another command to a java-based webserver that runs a command to start the instance, the whole mechanism is a joke (maybe that's your problem): It frequently reports "instance started successfully" when in fact it did not. And finding the reason for that is a real challenge. On one machine we have, it fails always after having booted the machine, and works after the SAP hostagent is killed (and restarted). The more SAP thinks they are part of the operating system, the more unreliable the whole system becomes.
It seems to be difficult to add a reliable layer on top of unreliable software...
Regards,
Ulrich

<pre wrap="">is there a bug in SAP HANA resource ? crm_mon shows that cluster started
the resource and keep the HANA resource in slave state, while in actual
cluster doesn't start the resources, we found following events in the logs:
