Auto discovery is supported only for tiers that do not have GCO configured. For any tier with GCO configured, virtual IP is the only supported communication mechanism.

Auto discovery is configured in following scenarios:

Configuring auto discovery for fresh installations: This is automatic and no user intervention is required.
Configuring auto discovery for upgrades: The procedure for this is described below.

Caution:

Do not set auto discovery on a tier that has GCO configured.

Before configuring auto discovery, ensure that vbsapp resource is brought offline.

To configure auto discovery of IP address of VBS daemon on a cluster:

Log on to any node of a cluster that is a part of your VBS.
Make the configuration read-writable.
```
# haconf -makerw
```
Delete the IP resource configured for virtual IP of the VBS daemon.
```
# hares -delete csgip
```
Delete the NIC resource configured for virtual IP of the VBS daemon.
```
# hares -delete csgnic
```
Delete the cluster IP address.
```
# haclus -modify ClusterAddress ""
```
Make the configuration read-only.
```
# haconf -dump -makero
```
