Unable To Start Backup Scheduler In VDP 6.x

You might come across issues, where backup scheduler does not start when you try it from the vdp-configure page or the command line using dpnctl start sched. It fails with:

2017/03/22-18:58:53 dpnctl: ERROR: error return from "[ -r /etc/profile ] && . /etc/profile ; /usr/local/avamar/bin/mccli mcs resume-scheduler" - exit status 1

And the dpnctl.log will have the following:

2017/03/22-18:58:53 - - - - - - - - - - - - - - - BEGIN
2017/03/22-18:58:53 1,22631,Server has reached the capacity health check limit.

If you run the below command you can see there are quite a few unacknowledged alarm that speaks about health check events not being acknowledged.

# mccli event show --unack=true | grep "22631"

1340224 2017-03-22 13:58:53 CDT WARNING 22631 SYSTEM   PROCESS  /      Server has reached the capacity health check limit.
1340189 2017-03-22 13:58:01 CDT WARNING 22631 SYSTEM   PROCESS  /      Server has reached the capacity health check limit.

To resolve this, acknowledge these events using the below command:

# mccli event ack --include=22631
