By default VLB health using the information in the VLB Manager object and the UUID as specified by the server

object. If the use_server_port is set, the server object's port is used. Otherwise the probe_port specified in

the health check object is used.

Typically, VLB health check probes are configured in the following manner:

1. Provide VMware login information by creating "VLB Managers".

2. Associate Equalizer servers with virtual machines on VMware.

3. Create VLB health checks.

4. Configure parameters for each health check.

5. Add vlb health check instances to server instances in server pools.

Messages will appear in the Equalizer log (on the global Logging > Event Log tab) when Equalizer

communicates with VMware, and when the state of a VM server changes. Otherwise, VLB works behind the

scenes to provide accurate and detailed VM server status information that Equalizer uses to make well-informed

load balancing decisions.

Enabling/Disabling VLB Health Check Probes

Enable/Disable VLB Health Check Probes in the GUI

VLB probes are enabled as soon as a health check instance is added to a server instance in a server pool. Default

settings for probe parameters are used unless specifically set on the Health Check Configuration screen.

Health checks can be disabled by checking the disable option on the Add Health Check screen as shown on

"Configuring VLB Health Check Probe Parameters" on page 386

Note - Health checks cannot be globally disabled and must be disabled for each health check.

Enable/Disable VLB Health Check Probes in the CLI

VLB probes are enabled as soon as a health check instance is added to a server instance in a server pool. Default

settings for probe parameters are used unless specifically configured on eqcli >.

Health checks can be disabled by entering the following in each server instance context:

eqcli >srvpool sp-spname si siname no hci hci-name

where:

sp-spname is the name of the server pool

si-siname is the name of the server instance in the server pool

hci-name is the name of the health check instance

Note - Health checks cannot be globally disabled and must be disabled for each health check instance.
