Below are the steps required to follow to configure a particular TAC server to not to participate in NLB in TAC array. This article only applies to a situation where integrated NLB is used for array load balancing.
IMPORTANT: Following steps needs to do before configuring NLB in the TAC array cluster.
- After all array members are joined, open regedit tool on TAC array manager.
- Create this registry key, if one doesn’t exist:
- Create a String value, with key “ArrayMemberIgnoreNlb”.
- Set the string value to FQDN name of server, which should be excluded from NLB, example:
NOTE: Multiple TAC server names can be used, each name should be separated with semicolon (;)
- Now, TAC server member which is excluded from NLB needs to have binding IP address assigned, instead of NLB IP which is used in TAC configuration.
- Open Array Management window:
- Select address override and press “Next”:
- Press “Add” button.
- Select array member that is excluded from NLB and configure re-map of NLB IP and port to dedicated IP and port for the array member:
The source IP is NLB IP and destination IP is dedicated IP on the array member on external NIC.
Do this for port 80 and port 443.
- Press OK to close add dialog.
- Repeat for other required ports and IPs.
- Press Finish.
- Apply configuration
This will exclude the array node from being participated to NLB operation. after apply configuration completed, you may do the NLB configuration for rest of the nodes.
