cluster network IP

  • Doing first 2012 active/passive cluster install. On the screen which looks the same as 2008 where it needs to validate the cluster network I put in the IP I was give to link to the sql instance name. It fails and tells me it can not validate the ip address. I can't even ping the IP from a command prompt. Am I missing something, I don't think this will work and validate if I can't ping it.

  • Try to figure it out why you even can't ping that IP from command prompt.

    If you can not ping it, SQL cannot validate it.

    For a 2 node single instance cluster,this is what you need

    One IP for the actual Windows Cluster

    One IP for the SQL server instance

    One IP for the MSDTC virtual ip

    One IP for the Public NIC (each node)

    One IP for the heartbeat network

    Are you meeting those requirements? ... also, your public NIC and SQL server instance virtual IP, should be on same subnet.

    Also, you do not mention which Os you are using. But if you are using Windows 2008R2 or similar, please ensure it is fully patched (both nodes). And that you can ping via IP and name to other node. I also like to ping (name and IP) the Domain Controller as well; MS Cluster uses AD a lot, so you need to ensure both nodes can ping the DC too.

  • thanks you are validating what I thought, my network guy thinks the install will create the IP, I always thought the IP had to be setup and valid first. If I can't ping it no way for sql to validate it

    The install will create a clustered resource for the IP address you supply and link it to the Virtual network name. The IP address must be a free address that is not already in use.

  • right but if the ip is invalid (can't ping it) the resource will never be created,

  • Are you saying you have pre created a cluster application and clustered IP address resource and thats why you expect to be able to ping it?

  • no just on the screen where you need to put in the IP address for the network resource during the inital cluster setup, you put in the ip and it won't validate

  • Are you selecting the correct network from the network list?

    Can you post a screenshot of the installer screen with any error messages?

  • here it is I think this is a straightforward issue

  • What is network 1
