Click the Patterns tab and activate the High Availability pattern in the pattern list.

Hi,

prior to that instruction it says:

Have you installed the extension on your server(s)? If not, this can be done via yast add-on.

Hi,

in the link to the docs you mentioned, under the section “Communication Channels” it says:

[QUOTE]At least two TCP/IP communication media per cluster node. The network equipment must support the communication means you want to use for cluster communication: multicast or unicast. The communication media should support a data rate of 100 Mbit/s or higher. For a supported cluster setup two or more redundant communication paths are required. This can be done via:

  • Network Device Bonding (to be preferred).
  • A second communication channel in Corosync.[/QUOTE]

So I guess you’re not forced to, but it’s recommended to bond the interfaces.
