条件:
Heartbeating over IP interfaces
•IPAT via IP Aliases
•Any type of non-concurrent resource group
要求:
With IPAT via IP Aliases, HACMP has the following requirements regardless of the resource group type:
•All boot interfaces on any node must be configured on different subnets. This is required for correct operation of heartbeating. (Otherwise, having multiple interfaces on the same subnet would produce multiple subnet routes. This prevents reliable heartbeating and failure detection.)
•All service IP addresses must be configured on different subnets than any of the boot addresses. This requirement prevents any possibility of having multiple routes leading to the same subnet.
•Multiple service IP labels can be configured on the same subnet, because HACMP sends heartbeats only across the boot IP addresses. |
