Solution 2147027.1 : Diameter Signaling Router (DSR) - "Event_Number: 31225 - HA Service Start Failure" Observed On All MP Blades After DSR Upgrade To 7.1.2 From 7.0.1

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 7.0 and later
Information in this document applies to any platform.

Symptoms

After DSR upgrade from 7.0.1 to 7.1.2 below alarm is observed on all C level blades:

Event_number: 31125 - HA Service Start Failure

Instance: DSROAM_Proc

NETWORK_ELEMENT: SOAM SERVER: SBRS-2 EVENT_NUMBER: 31225 SEVERITY: MAJOR PRODUCT: Platform PROCESS: cmha TYPE: HA INSTANCE: DSROAM_Proc NAME: HA Service Start Failure DESCR: The required high availability resource failed to start ERR_INFO:GN_WARNING/WRN Unregistered required subResources(0)^^ [11914:HaResource.cxx:371]

Cause

Upgrade is being done from DSR 7.0 to DSR 7.1.

This was not a fresh install on DSR 7.0.

Any system where DSR upgrade is done from DSR 7.0 to DSR 7.1 or higher, Event Number "31225 - HA Service Start Failure" will be generated for all C level blades.
This alarm has no impact because it gets generated with instance - DSROAM_Proc, which is optional for MP blades (C level).
It is not expected that DSROAM_Proc process runs on MP blades.
Any system that will be upgraded to 7.1 or higher through 7.0 will be having this issue as 7.0 is broken in between.
Since 7.0 was not raising the alarm it got unnoticed in 7.0 but the problem was there in 7.0 also
In DSR 7.1, Comcol has started raising alarm for such conditions.
In DSR 7.0 the upgrade loader file load.dsr.upgrade.7.0.5+BUG19111064 gets executed automatically (RPM 7.0.5) hence this alarm is not generated there.
But when upgrading from DSR 7.0 to DSR 7.1 or higher this loader file does not gets executed automatically.
This loader file gets executed when upgrading from RPM version 7.0.5
When upgrading from DSR 7.0.1 to DSR 7.1.2 the RPM version is 7.0.23 to 7.1.20 as seen in upgrade logs, which does not covers RPM version 7.0.5

From Upgrade logs:

o 1464101482::da01_dsr_app_enable.sh: Executing upgrade loaders...
o 1464101482::Upgrading Idb tables data from '7.0.23' to '7.1.20'...

Solution

Workaround to fix this issue is to execute the below loader file on Active NOAM:

/usr/TKLC/dsr/prod/maint/loaders/upgrade/load.dsr.upgrade.7.0.5+BUG19111064

This loader file will mark DSROAM_Proc process as optional for MP blades hence clear the alarm.

Bug# 23540150 - DSROAM_Proc configured as a required HA resource but not started on MPs". Is opened to fix this issue.
