Chapter 2: mx Commands 65

mx snapshot – snapshot commands

Use the following commands to create or destroy hardware snapshots.

Show snapshot options for the storage array associated with a volume:

mx snapshot showcreateopt <volume>

Create a snapshot:

mx snapshot create [--terse] [<options>] <volume>

The --terse option causes only the name of the snapshot volume to be

printed on success.

Destroy a snapshot:

mx snapshot destroy <volume>

mx vhost – virtual host commands

Use the following commands to configure virtual hosts or to display their

status.

Add a new virtual host:

mx vhost add

[--policy autofailback|nofailback]

<vhost>

<network_interface> ...

The --policy option specifies 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.

<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.
