To remove an LLT link

Run the following command to remove a network link that is configured

under LLT:

# lltconfig -u devtag

If the link you removed is configured as a PrivNIC or MultiPrivNIC resource,

you also need to modify the resource configuration after removing the link.

If you have configured the link under PrivNIC or MultiPrivNIC as a failover

target in the case of link failure, modify the PrivNIC or MultiPrivNIC

configuration as follows:

# haconf -makerw

# hares -modify resource_name Device link_name \

device_id [-sys hostname]

# haconf -dump -makero

For example, if the links lan1, lan2, and lan3 were configured as PrivNIC

resources, and you want to remove lan3:

# haconf -makerw

# hares -modify ora_priv Device lan1

0 \

lan2

where lan1 and lan2 are the links that you want to retain in your cluster.

# haconf -dump -makero

Configuring aggregated interfaces under LLT

If you want to configure LLT to use aggregated interfaces after installing and

configuring VCS, you can use one of the following approaches:

■ Edit the /etc/llttab file

This approach requires you to stop LLT. The aggregated interface configuration

is persistent across reboots.

■ Run the lltconfig command

This approach lets you configure aggregated interfaces on the fly. However,

the changes are not persistent across reboots.
