Updating the VIOS for a dual configuration

You can update the Virtual I/O Server (VIOS) partition for a dual configuration by using the VIOS command line.

If you configured the first VIOS partition as a single VIOS setup and you need to update it for a dual VIOS setup, complete the following steps:

Log on to the first VIOS partition.
Type cfgdev to configure the virtual Ethernet adapter on the VIOS partition.
List the virtual Ethernet devices that are configured on the VIOS partition:
```
lsdev -vpd | grep Virtual | grep ent
```
Output similar to the following is displayed:
```
ent6 U8233.E8B.061AB2P-V1-C3-T1 Virtual I/O Ethernet Adapter (l-lan)
ent4 U8233.E8B.061AB2P-V1-C2-T1 Virtual I/O Ethernet Adapter (l-lan)
```
Where ent6 device is the virtual Ethernet adapter, which is used as the control channel.
Query the Ethernet device that is the shared Ethernet adapter:
```
lsdev -type sea
```
Output similar to the following is displayed:
```
Name Status    Description
ent5 Available Shared Ethernet Adapter
```
To update the shared Ethernet adapter and to add the shared Ethernet adapter failover functions, enter the following command:
```
chdev -dev ent5 -attr ctl_chan=ent6 ha_mode=auto
```
