CUCM 9.1.2 SUB DRF LOCAL IS DOWN

Hello,

I am having a problem backup my cluster  .

When enter the disaster recovery system everything is slow (most of the time )

Some times I get this message

"Unable to process request, master agent is busy"


In addition the service DRF local in the sub is "down"

after restart the service is up only for few minutes .

 

I found this post

https://supportforums.cisco.com/discussion/12070896/drf-local-service-stops-subscriber

 

but I am no sure this is same problem and didn't understand completely. 

Any ideas ?

 

Thank you ,

Hi Ben,

As per my reply on the earlier post as well ( https://supportforums.cisco.com/discussion/12070896/drf-local-service-stops-subscriber )

If the service is failing repeatedly on the subscriber, first please check for any core dumps using the following command on subscriber cli

utils core active list

If no core dumps are found then we need to collect DRF Master and Local traces from the subscriber to look for any known bugs.

How do I collect DRF Master and Local traces from the subscriber?

Cisco Unified Serviceability

Cisco Unified Serviceability > Trace > Configuration > Select any node > Backup and Restore services > Select Master Agent > Make sure that 'Debug Trace Level' is set to 'Debug' > Check 'Apply to all nodes'

Now, do the same for Local Agent service

Now, reproduce the issue and collect the traces for the time stamp through Real Time Monitoring Tool.

When I try to do it I get different error

Local Agent is not responding. This may be due to Master or Local Agent being down

 

 The local and master agent in both sub and pub are running .

This looks to be an ipsec

This looks to be an ipsec cert issue. if this is a production system, i would suggest opening a TAC case to get the exact steps for cert regenration.

Hi Ben, 

 

Ideally, it should show Synchronized and if u check in the GUI, should show Accessible under OS administration ---settings---NTP servers.

 

can u check whether configured NTP are reachable or not?

Hi, Cisco highly recommends

Hi,

 

Cisco highly recommends configuring the publisher to point to a Stratum-1, Stratum-2, or Stratum-3 NTP server to ensure that the cluster time is synchronized with an external time source.

in our case ,it is 9

regds,

aman

Can you restart the DRF

Can you restart the DRF Master/Local services on all nodes after correcting that?

 

May still need to regenerate the IPSec certificates to resolve.
