Validation Checks for Scalable Services

Whenever you create or update a resource with the scalable property set to TRUE, the RGM validates various resource properties. If you do not configure the properties correctly, the RGM rejects the attempted update or creation.

The RGM performs the following checks:

• The scalable resource must declare a resource dependency on one or more existing shared address resources.

  Every node in the Nodelist for the resource group that contains the scalable resource must appear in the NetIfList property of the SharedAddress resource.

  The Nodelist of the scalable resource group must be a subset of, or the same as, the combination, or union, of the following two node lists:

  • The Nodelist for the resource group that contains the SharedAddress resource.

  • The Nodelist that is listed in the AuxNodeList property for the SharedAddress resource.

  ---

  Note - If you include all nodes in the node list for the scalable resource's resource group in the node list for the shared address' resource group, you do not need to set the AuxNodeList property.

  ---

• The Port_list property must not be empty and must contain a list of port-protocol pairs. You must append a slash (/) to each port number, followed by the protocol that is being used by that port. For example:

  Port_list=80/tcp6,40/udp6

  You can specify the following protocol values:

  • tcp, for TCP IPv4

  • tcp6, for TCP IPv6

  • udp, for UDP IPv4

  • udp6, for UDP IPv6
