HANA DB resource failed to start

This document (000020948) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server for SAP Applications 15

SUSE Linux Enterprise Server for SAP Applications 12

Situation

Starting the HANA DB cluster resource (for ex: rsc_HA0_HDB00) consumed a long time, and failed with a timeout error. However, it can be successfully started manually (outside the cluster control) while the cluster was in maintenance mode.

Resolution

Extend the timeout parameter for the HANA DB resource for both stop and start, for example, from exiting one (3600 sec.) to a new one (ex:7200 sec.).

1. Enable cluster maintenance mode

# crm maintenance on

2. In case the cluster reports an error due to failure to start, then "cleanup" any failures before disabling the cluster maintenance mode. This will avoid restarting the HANA DB by the cluster

# crm resource cleanup

3.Edit the cluster configuration to update the timeout parameter of the start and stop operations.

# crm config edit

Before

primitive rsc_HA0_HDB00 ocf:suse:SAPHana \
        op start interval=0 timeout=3600 \
        op stop interval=0 timeout=3600 \

After

primitive rsc_HA0_HDB00 ocf:suse:SAPHana \
        op start interval=0 timeout=7200 \
        op stop interval=0 timeout=7200 \

4. Disable cluster maintenance mode

# crm maintenance off

Cause

The HANA DB failed to start by the cluster within the designed start timeout. The start timeout needs to be extended.
The below errors will be reported in the logs, which show the start operation for the HANA DB resource for this node ended with the failed status due to time out.

pacemaker-execd[xxx]:  warning: rsc_HA0_HDB00_start_0 process (PID xxx) timed out
pacemaker-execd[xxx]:  warning: rsc_HA0_HDB00_start_0:xxx - timed out after 3600000ms
pacemaker-execd[xxx]:  notice: finished - rsc:rsc_HA0_HDB00 action:start call_id:25 pid:xxx exit-code:1 exec-time:3604053ms queue-time:0ms
pacemaker-controld[xxx]:  error: Result of start operation for rsc_HA0_HDB00 on xxx: Timed Out
