Introduction

This document describes how to use a Q3 Agent in the recovery of a Control and Monitoring Processor (CMP) failure condition that occurs due to corrupt files on a CMP. This document uses the Blue Devil (1.5.1) release of the Q3 Agent.

Note: Do not use this procedure if the CMP has had another agent, or a release other than Blue Devil previously loaded.

Note: The Q3 Agent is NOT the same as the TL1 Agent.

Prerequisites

Requirements

Background Information

Preparation

This document is a continuation of the diagnosis process, and the required tools must be already available. The additional item that you require is Agent Q3 Blue Devil version 1.5.1 package. The distribution is in the companion Zip archive file named Agent_1.5.1_M.tar.gz.

After you diagnose that the problem relates to one or more corrupt files, and not the file system, you can start the recovery process. The Recovery Steps section explains the recovery process.

Recovery Steps

This section describes the recovery procedure in four steps.

Step 1: Extract the Agent Q3 Installation Files

C:\Agent is the target disk to unzip in the distribution archive Agent_1.5.1_M.tar.gz. Complete these steps:

  1. Create the Agent directory under C:\, if the directory does not already exist.

  2. Copy the file Agent_1.5.1_M.tar.gz into the Agent directory (see Figure 1).

    Figure 1 – Copy Agent_1.5.1_M.tar.gz into the Agent Directory

  3. Double-click Agent_1.5.1_M.tar.gz to open the WinZip program (see Figure 2).

  4. Extract all files into the C:\Agent directory, (see Figure 3).

    Figure 3 – Extract the Files

  5. Check whether the C:\Agent directory contains the list of files that appear in Figure 4.

Step 2: Remove the Configuration Files

After you extract the required files, you can remove the configuration files.

  1. Connect with a Telnet session on the CMP.

    You do not receive any prompt for a password or login. Complete these steps:

    1. Click the Start button of the Windows program that you use, then select Run.

    2. Type telnet ip address of the CMP (see Figure 5).

      Figure 5 – Type telnet ip address of the CMP

      15800_cmp_recovery_procedure-5.gif

      A Telnet session opens.

      Figure 6 – Telnet Session

  2. Type these commands at the Telnet prompt:

    Telnet+>rm PERSISTENT
    Telnet+>rm netosi.cfg
    Telnet+>rm genPers.dat
    Telnet+>rm genPers.idx
    Telnet+>rm moPers.dat
    Telnet+>rm moPers.idx
    

    You can ignore any error messages that appear.

Step 3: Ascertain Whether the CMP Card is 16 M or 64 M RAM

Next, you must ascertain the type of CMP card.

Issue this command:

Telnet+>vinfo

The 16 M CMP output appears like this:

Telnet+> vinfo 
Volname 	 Size 	 	Free  		Num files 
9.0.2   	25004  	11611  	104

For the 6 4M cards, the size is equal to 120004.

Note: The vinfo command shows Flash memory dimension in blocks.

Step 4: Install the Q3 Agent Blue Devil Version 1.5.1

Finally, install theQ3 Agent. Complete these steps:

  1. The configuration files of the Agent Q3 reside in C:\Agent.

  2. Connect with a File Transfer Protocol (FTP) session on the CMP. You receive a prompt to enter a login and password.

  3. Click on Start button of your Windows program, and select Run. Type ftp ip address of the CMP (see Figure 7).

    Figure 7 – Type ftp ip address of the CMP

    A Telnet session opens (see Figure 8).

    Figure 8 – Telnet Session

  4. Insert the User = ROOT and Password = WMUX (see Figure 9).

    Figure 9 – Insert the Username and Password

  5. Type these commands at the FTP prompt:

    ftp>binary
    ftp>hash
    
    Figure 10 – Commands to Type at the FTP Prompt

  6. Type this command at the next FTP prompt:

    ftp>lcd C:\Agent
    
    Figure 11 – Next Command at FTP Prompt

  7. Copy the files on the CMP with these commands:

    ftp>put agent.abs
    ftp>put CPT_INFO
    ftp>put timeout.cfg
    

    If the CMP has 16 M RAM memory, you must enter this command:

    ftp>put bpool.cfg
    

    If the CMP has 64 M RAM memory, you must enter this command:

    ftp>put bpool.cfg.64M bpool.cfg
    

    This prompt appears:

    ftp>bye
    

    The installation is complete.

If on site, complete these steps in order to reset the CMP:

  1. Locally press the CMP reset button.

    If you access the node remotely, you can type reset from a Telnet session, and press ENTER.

  2. Check if the recovery procedure is successful. Complete these steps:

    1. CMP display must show a fixed 6.

    2. Cisco Photonics Local Terminal (CPLT) must show the correct Network Element (NE) inventory.

    3. Delete the monitor.abs file with this command:

      Telnet+>rm monitor.abs
      

      This is the end of the procedure.
