APIC-EM GUI access hangs after reboot

This behavior is very consistent - to recover out of the condition need to do every time a "reset_grapevine backup_restore".

I am sure I am missing something but I haven't found anything in documentation of by googling it - on the surface all seems fine.

Any help / advice greatly appreciated - can't really do my POC if I have to reset it every time

Running w/ 22G RAM, 6vCPU. This is what I am doing (after fresh install or after reset_grapevine backup_restore")

- login to GUI

- growing a few more services (task_service, topology, network_poller, etc) - making sure in "host" tab resource consumption is "green"

- then in CLI "gracefully" shut down

   grape host display : obtain host_id

   grape host evacuate <host_id>  (then checking task for completion)

   grapectl shutdown

   sudo shutdown -h now

After shutdown & poweroff I start VM again

   grape host display : obtain host_id

   grape host enable <host_id>

Get in CLI to check services - once the core services are running

Trying to login in GUI (e.g. developer console https://<apic-em-ip>:14141)- no luck - the waiting wheel spins forever

Then I manually grow a few more services I assume should run (postgres, rbac, etc) - tough luck, same behavior, cannot login in GUI.

Here are my running services at this point  ( grape instance status)

Resource consumption is absolutely minimal at this point

From multiple tries at this point only way out is either reinstall or "reset_grapevine backup_restore"

Re: APIC-EM GUI access hangs after reboot

Answered my own question - I was using an older shutdown / restart procedure - now with 1.3.3 the right sequence is the following

Power Down

sudo /home/grapevine/bin/harvest_all_clients

sudo shutdown -h now

Power On

grape config update enable_policy true

That's it and it kind of works just that it starts ALL the clients and I probably do not need all for a lab POC

Now the "grape config update" has other options like "enable_dev_mode" or "low_memory_install"  - but haven't been able to find anywhere any documentation or thread on how to use these. Any suggestion?

Thanks

Re: APIC-EM GUI access hangs after reboot

Hi Ro,

the other commands are not for general use.

As you know, the commands for shutdown/restore are here: Cisco Application Policy Infrastructure Controller Enterprise Module Deployment Guide, Release 1.3.x - Deploying the …

There are interdependencies between the services, so this is why they are all started.  You can turn off some services-bundles (IWAN - which is it's own bundle post 1.3.2) and Pnp.  You can do this from the admin/app-management menu.
