4.1 System Topology Check

Procedure 1: System Topology Check

This procedure is part of feature activation preparation and is used to verify the system topology of the DSR network and servers.
  1. Log in to the NOAM VIP GUI, establish a GUI session on the NOAM server by using the VIP address of the NOAM server.
  2. Open the web browser and enter the URL, http://<Primary_NOAM_VIP_IP_Address>
  3. Log in as the guiadmin user.

  11. Analyze and plan the DA-MP re-start sequence. During PCA Activation procedure 6 for activation of PCA on an existing system, it will be necessary to restart the application process on each DA-MP server. This step is to plan the order and level of parallelism for the process restarts such that signaling disruption is minimized.Analyze system topology and plan for any DA-MPs which will be out-of-service during the feature activation sequence.Analyze system topology gathered from Step 5 to 10. Determine exact sequence which DA-MP servers will be restarted (with the expected out-of-service periods).

    Note:

    It is recommended that no more than 50% of the MPs be restarted at once.
