Validation Checks for Scalable Services

Whenever a resource is created or updated with the scalable property set to TRUE, the RGM validates various resource properties. If the properties are not configured correctly, the RGM rejects the attempted update or creation. The RGM performs the following checks:

• The Network_resources_used property must not be empty and contain the names of existing shared address resources. Every node in the Nodelist of the resource group that contains the scalable resource must appear in either the NetIfList property or AuxNodeList property of each of the named shared address resources.

• The RG_dependencies property of the resource group that contains the scalable resource must include the resource groups of all shared address resources that are listed in the scalable resource's Network_resources_used property.

• The Port_list property must not be empty and 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
