SLP directory agent configuration

Review these suggestions when you configure the SLP directory agent.

About this task

Configure the SLP directory agents (DAs) to circumvent the multicast limitations. With statically configured DAs, all service requests are unicast by the user agent. Therefore, it is possible to configure one DA for each subnet that contains storage devices that are to be discovered by IBM Spectrum Control. One DA is sufficient for each of the subnets. Each of these DAs can discover all services within its own subnet, but no other services outside its own subnet. To allow IBM Spectrum Control to discover all the devices, it needs to be statically configured with the addresses of each of these DAs. This operation can be accomplished by using the IBM Spectrum Control Discovery Preference panel.

You can use this panel to enter a list of DA addresses. IBM Spectrum Control sends unicast service requests to each of these statically configured DAs, and sends multicast service requests on the local subnet on which IBM Spectrum Control is installed. Configure an SLP DA by changing the configuration of the SLP service agent (SA) that is included as part of an existing CIM Agent installation. This action causes the program that normally runs as an SLP SA to run as an SLP DA.

Note: The change from SA to DA does not affect the CIMOM service of the subject CIM Agent, which continues to function normally, sending registration and deregistration commands to the DA directly.
