Hi,

1. The IIS website binding (go to IIS manager -> Sites -> select Orion website ->in right pane select "Bindings") must be set to All Unassigned or at least shouldn't have set restriction to set of IPs

2. Virtual IP must be routable

3. DNS should point to that VIP according to the client zones

Hi Jan,

Thanks for replying.

I have bind the IPS , how can I change it All Unassigned ?

Jan_Pelousek

Just edit the binding. Select "All Unassigned" or add additional binding for VIP. Potentially you may change it also by the Configuration Wizard, but I personally don't consider this as necessary. Just pay attention next time during the CW run so you won't overwrite the current binding.

Thanks for your comments guys.

let me tell you the configured environment.

Step : 1: First I have installed the NMP/NCM/NTA of Primary Server A and complete the configuration wizard with binding the website to specific IP.

Step 2: Download the HA installer and install it on secondary server B and complete the configration wizard with binding the website to specific IP.

So now If I bind the website to All unassigned on primary, will impact to my secondary environment ?

Please suggest.

Sorry I missed

Step 3 : I have created the pool using Virtual IP

Thanks Jan....

Its working fine now

so now if I installing an additional poller then where i need to point it?

VIP or primary IP or secondary IP?

Jan_Pelousek

When installing the APE you just need to contact some of the active servers to get installed product set, so on initial screen just put some IP where the primary is currently reachable. In the configuration wizard just point this server to the orion database (should be already prefilled by installer, so eventually you'll enter just DB password).

Jan_Pelousek

The configuration wizard is configuring the local IIS, so setting on one server won't impact your second server, however wih respect to hooked features, like report scheduler and so on + the fact you'll probably want to reach your web server the same way prior and after failover, I'd recommend you to set the bindings the same on both primary and secondary server

Thanks Jan...

this is the issue I am getting while installing the additional poller

Jan_Pelousek

This may be caused by various things. Make sure, that:
- Hostnames of the target machine and the primary machine are resolvable to IP (e.g. you can ping each other by ping)

- Ports 17777 and 17778 are opened between machines in both directions (firewalls, antiviruses and similar blocking stuff)

- System time on both machines are in sync. Ideally also timezones match
