[Pacemaker] howto group resources without having an order

[Bauer, Stefan (IZLBW Extern)]

What do you mean by "alias". The ocf:heartbeat:IPaddr2 adds a secondary IP address to a interface.
-> Alias is he original term used from the ocf:heartbeat:IPaddr2 manpage for the function.

->Description

->This Linux-specific resource manages IP alias IP addresses. It can add an IP alias, or remove one. In addition, it can implement Cluster Alias IP functionality if invoked as a clone resource.

As Lars already noted. Or make a constraint set, as Florian already noted:

colocation c-set inf: (OVPN1 OVPN2 ...) myGroup

-> Can you recommend a documentation about howto specify a colocation? What is the function of the "(" for example.
