host# crm ra info ocf:heartbeat:IPaddr2
Manages virtual IPv4 addresses (Linux specific version) (ocf:heartbeat:IPaddr2)
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.
Parameters (* denotes required, [] the default):
ip* (string): IPv4 address
The IPv4 address to be configured in dotted quad notation, for example
"192.168.1.1".
