Error when coming out of standby: hdbdaemon HDB Daemon not running

This document (7021376) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server for SAP Applications 11 Service Pack 3
SUSE Linux Enterprise Server for SAP Applications 11 Service Pack 4
SUSE Linux Enterprise Server for SAP Applications 12 Service Pack 1
SUSE Linux Enterprise Server for SAP Applications 12 Service Pack 2
SUSE Linux Enterprise Server for SAP Applications 12 Service Pack 3

Situation

After upgrading to some versions of SAP, a bug is introduced which causes an error when trying to bring a node out of standby.

Examples of the bug seen in messages or cluster logs:-

     <date+time> <node> SAPHana(<resource>)[11752]: ERROR: ACT: SAPHANA Instance <instance> start failed:  08.05.2017 09:58:12 WaitforStarted FAIL: process hdbdaemon HDB Daemon not running.

Also seen at the same time:

     <resource>  on <code> 'unknown error' (1): call=69, status=complete, exit-reason='none', last-rc-change='Mon May  8 09:57:52 2017', queued=0ms, exec=19762ms



Resolution

1: Ask SAP to provide a patch for the version of SAP software being used

2: Upgrade to a version of SAP where the problem is already fixed

3: Live with the inconvenience of the issue and manually re-start the SAP instance (after coming out of standby and the error is encountered, the slave node must be re-registered and any problem resources must be cleaned up).

The issue is known to be present in (at least) these 2 SAP versions:-

     1.00.111.00.1454183496
     1.00.112.00.1457525470


The issue appears to be fixed/not present in version:

    1.00.121.00.1466466057


It is assumed that any SAP software versions later than 1.00.121.00.1466466057 will also not suffer from the issue.



Cause

SAP introduced a bug which is triggered when the SAPHanaSR resource agent executes specific 'legal' SAP commands. This is not a SUSE OS or SUSE clustering issue, it is a bug in some versions of the SAP software.
