--policy

autofailback|nofailback

The failback action that the virtual host will take following failover to a

backup node. autofailback will fail back when a higher-ranked node

provides equal or greater services than the backup node; nofailback fails

back only if a higher-ranked node provides greater services than the backup

node. autofailback is the default.

--activitytype single|always

Whether, upon server failure, the virtual host will move to an active server if

all associated service and device monitors are inactive or down. If always is

specified, the failover will occur. If single is specified, the failover will not

occur and the virtual host will not be made active anywhere. single is the

default.

<vhost> can be either the hostname or the IP address for the virtual host. If

you specify the hostname, it can include up to 32 characters.

The order in which you specify the network interfaces determines the

ordering for failover. The first network interface is the primary interface;

network traffic for the virtual host goes to the server providing this

interface. The remaining network interfaces are backups. Each network

interface must be located on a different server.

Modify (update) an existing virtual host:

mx vhost update [--application <application>]

[--policy

autofailback|nofailback]

[--activitytype single|always] <vhost>

([<network_interface> ...][ALL_SERVERS <network_interface>])

Use this option to change the arguments or the ordering of the network

interfaces for failover.

Move a virtual host to another server:

mx vhost move [--policy autofailback|nofailback]

[--application <application_name>] [--activitytype

single|always] <vhost> ([<network_interface> ...][ALL_SERVERS

<network_interface>])

Delete a virtual host:

mx vhost delete <vhost>
