Enabling All IP Addresses On A Multi-Homed Pool Host – Zenoss

Applies To

Zenoss 5.x
Control Center 1.x

Summary

If a Resource Manager pool host has multiple IP addresses (multi-homed), there are cases where Control Center does not recognize all of the IP addresses. This KB describes the procedures to enable Control Center to recognize the multiple addresses of a multi-homed pool host. The procedures include those for single server installations and delegate host installations.

Procedures

The following procedures enable all IP addresses on multi-homed pool hosts.

Single Server Installation

Perform the following procedure if the installation is a single server installation. If the installation is a delegate host installation, proceed to the Delegate Host procedure.

Stop Resource Manager:
```
serviced service stop zenoss.resmgr
```
Edit the /etc/default/serviced file to add or uncomment the following line and add the IP address(es), for example:
```
SERVICED_STATIC_IPS=10.90.34.120,10.90.34.121
```
Restart serviced
```
systemctl restart serviced
```
Determine the Host ID:
```
serviced host list
```
Remove the host:
```
serviced host rm <hostid>
```
Re-add the host:
```
 serviced host <hostname or IP>:4979
```
Confirm all IP addresses are now listed and correct for all services assigned an IP address:
```
serviced host list -v
```
NOTE: The IP address(es) can now be assigned in Control Center.
Start Resource Manager:
NOTE: Review and verify that all services with IP addresses assigned to them still have the correct IP addresses before restarting services.
```
serviced service start zenoss.resmgr
```

Delegate Host

Perform the following procedure if the installation is a delegate pool host:

Stop services running on the host:
```
serviced service stop <service name>
```
Edit the /etc/default/serviced file to add or uncomment the line and add all necessary IP addresses, for example:
```
SERVICED_STATIC_IPS=10.90.34.120,10.90.34.121
```
Restart serviced:
```
systemctl restart serviced
```

Perform the following on the Control Center master host:

Determine the Host ID:
```
serviced host list
```
Remove the host:
```
serviced host rm <hostid>
```
Re-add the host:
```
serviced host <hostname or IP>:4979
```
Confirm all IP addresses are now listed and correct for all services assigned an IP address:
```
serviced host list -v
```
NOTE: The IP addresses(es) can be assigned in the Control Center.

On the delegate host, re-start the stopped services running on the host:

NOTE: Review and verify that all services with IP addresses assigned to them still have the correct IP addresses before restarting services.

```
serviced service start <service name>
```
