Cisco CVP Call Server - SideB Down When SideA is Up

[ln33147]

Dears,

It's a UCCE environment version 12.0.

We're facing an issue on the CVP servers where Call Server can't be up on both sides at the same time. If SideA is up then CallServer SideB is down and we cannot start it and if SideB is up then we cannot start CallServer SideA.

Any help is greatly appreciated.

Thanks in advance

Are you talking about the CVP servers themselves, or the PGs that the CVP servers talk to?

For instance, if you go into CVP OAMP, do both CVP (and/or VXML) servers show up/partial/down?

The CVP servers themselves should be 100% independent of each other.

Hello Bill,

Currently in OAMP CallServerA is up and CallServerB is down and if I try to start it nothing happens, it doesn't even go tp partial.

If I shutdown CallServerA and start CallServerB, CallServeB goes up but CallServerA stays stuck in "Down".

Could it be a licensing issue?

Hi,

Check the call server services in services.msc

Also, verify in PG setup how you are configuring PIM1 & PIM2 for CVP. VRU connection port will be the same for all the CVP PIM or different ( your wish)

 But for CVP PIM1 IP will be the CVP1 call server and PIM2 for the CVP2 call server IP.

or

If you're facing this issue after Windows 2012 to 2016 Upgrade please check the network adapter interface metric value in PG and Rogger.

Configure Network Cards

Procedure

Step 1 In the virtual machine, open Network and Sharing Center.

Step 2 Click Change adapter settings.

Step 3 Rename Ethernet 0 to public for the Public network card.

Step 4 Rename Ethernet 1 to private for the Private network card.

Step 5 Assign an interface metric value for the network adapter:

1. a) Select the network adapter and right-click Properties.
2. b) In the Networking tab, select the appropriate Internet Protocol version and click Properties.
3. c) In the Internet Protocol Version Properties dialog box, click Advanced.
4. d) In the IP Settings tab, uncheck the Automatic metric checkbox and type a low value in the Interface

metric text box.

A low value indicates a higher priority. Make sure that the Public Network card should have a

lower value compared to the Private Network card.

By default, the value of the Interface Metric property for a network adapter is automatically

assigned and is based on the link speed.

Note

1. e) Click OK to save the settings.

Repeat the steps to assign an interface metric value for the internal/private cluster communication network

adapter.

I would bet it is like Ramamoorthy mentioned, that when this was set up they confused the CVP addresses when they did the PIM setup.

I'm guessing this is a new install and has never worked/been tried in the past?

There shouldn't be any reason that both CVP servers can't be up and of course you'd normally want/need that to provide disaster recovery/redundancy.
