Setting up the Service Location Protocol Directory Agent SLP discovery startup methods Customize Performance Manager to run San Volume Controller cluster data-collection tasks

You can use these procedures to set up the Service Location Protocol (SLP) Directory Agent (DA) so that MDM can discover devices that reside in subnets other than the one in which MDM resides.

Steps

Perform the following steps to set up the SLP DAs:

  1. Identify the various subnets that contain devices that you want MDM to discover.
  2. Each device is associated with a CIM Agent. There might be multiple CIM Agents for each of the identified subnets. Pick one of the CIM Agents for each of the identified subnets. (It is possible to pick more than one CIM Agent per subnet, but it is not necessary for discovery purposes.)
  3. Each of the identifed CIM Agents contains an SLP service agent (SA), which runs as a daemon process. Each of these SAs is configured using a configuration file called slp.conf. Find the slp.conf file in the CIM Agent installation directory and perform the following steps to edit the file:
    1. Make a backup copy of this file and name it slp.conf.bak.
    2. Open the slp.conf file and scroll down until you find (or search for) the line ;net.slp.isDA = true. Remove the semi-colon (;) at the beginning of the line. Ensure that this property is set to true (= true) rather than false. Save the file.
    3. Copy this file (or replace it if the file already exists) to the the main windows subdirectory for Windows machines (for example c:\winnt), or in the /etc directory for UNIX machines.
  4. Restart the daemon process and the CIMOM process for the CIM Agent (refer to the CIM Agent documentation for your operating system for more details).
    Note:Note: The CIMOM process might start automatically when you restart the SLP daemon.
  5. You have now converted the SLP SA of the CIM Agent to run as an SLP DA instead. The CIMOM is not affected and will register itself with the DA instead of the SA. However, the DA will automatically discover all other services registered with other SLP SAs in that subnet.
  6. Go to the MDM Discovery Preference settings panel, and enter the host names or IP addresses of each of the machines that are running the SLP DA that was set up in the prior steps.
    Note:Note: Enter only a simple host name or IP address; do not enter a protocol and port number.
Result

When a discovery task is started (either manually or scheduled), MDM will discover all devices on the subnet on which MDM resides, and it will discover all devices with affinity to the SLP DAs that were configured.
