Starting Cisco WAN Manager

This section provides information about starting CWM. This section includes the following procedures:

•Starting CWM for the first time

•Performing a warm start of CWM

•Performing a cold start of CWM

---

Note These procedures describe CWM startup from a workstation running the Sun Solaris operating system.

---

Starting CWM for the First Time

This section describes how to start CWM for the first time. This procedure is also used to start CWM from a workstation that has been powered off.

---

Step 1 Turn on power to any peripheral devices, such as external disk drives, tape drives, or monitors, then turn power on to the workstation.

Observe the messages that are displayed on the workstation as it boots up, and wait for the login prompt. While the Solaris OS is booting, the HPOV SNMP Agent, the HPOV background processes, and the Informix database are also started.

Step 2 At the Solaris login window, click on Options > Session > CDE.

---

Note This step is necessary only on the first login. If asked during the login process, select CDE again.

---

Step 3 Login to the workstation as user svplus.

Step 4 Left click the TTT icon to launch the Style Manager and perform the following steps to save system resources:

a. Click on Screen, Screen Saver, and Screen Lock Off.

b. Click on Backdrop, select GrayDk, then click Apply.

Step 5 Use the CDE Menu Bar to change to screens Two, Three, and Four, and select the same options for those screens. Return to screen One and close Style Manager when completed.

Step 6 Right click on the desktop and select Programs > Terminal.

Move this window to the upper-right corner of the screen.

Step 7 Right click on the desktop and select Programs > Console.

Reduce the height of this window so it displays at least five lines (to enable you to monitor system messages). Move the window so that it rests on the CDE Menu Bar and all icons are visible.

---

Note Do not use the Console window for any purpose other than monitoring system messages.

---

Step 8 Left click the TTT icon to launch the Style Manager, then select Startup, Set Home Session..., and click OK.

This saves your startup login preferences.

---

Note In a CDE environment, if a Home Session has not been set, any previously opened applications will run. If the console and terminal windows do not open under CDE, right click the mouse on an empty portion of the background and select Programs > Console, then select Programs > Terminal.

---

Step 9 In the terminal window, enter CWM to display the CWM main menu.

---

Note If the error message "Environment Variable DISPLAY not set" is displayed when you attempt to start the main menu and the display is not being xhosted to another workstation, enter the following: setenv DISPLAY machine_name:0.0

---

Step 10 Enter 1 to select the Start Core option and press Return.

Observe the messages that are displayed. Notice the gateway and stand alone nodes socketed messages to the IP-LAN addresses.

A Link0 down message may be displayed, followed by a Link0 up for each gateway node (if communication is established to the gateway node), then a group of Link1 up messages for all nodes, if everything is working correctly.

There will probably be several ILOG RT-Broker messages; disregard these messages and the EMSD dumping message, if it is displayed. This is normal operation. Also disregard any server EMDAEMON not registered messages.

---

Note Additional messages will be displayed for PNNI nodes.

---

After you see the Link 0, Link 1, and gateway node messages indicating the connections are up, continue to the next step. (If there is a problem with a Link connection, you will not see all connections come up.

---

Note Stand alone MGX 8850 switches do not use Link protocol and will not show up in these messages. Feeder MGX 8850 switches act like MGX 8220 switches and do not display Link 1 messages.

---

Step 11 Press Return to redisplay the main menu.

At this point, you can issue other main menu options to start the CWM desktop or the Statistics Manager.

Step 12 Enter 3 to launch the CWM Desktop using your Web browser.

Step 13 From the CWM Desktop Topology, left click on the Statistic Collection Manager icon to launch the Statistics Manager application.

Minimize the Statistic Collection Manager window.

Step 14 Right click on the desktop and select Programs > Terminal to open another xterm window.

Step 15 In the new xterm window, enter ovw & to start the Openview application which opens the Openview graphical user interface (GUI) and the Event Manager.

The IP map contains HPOV's view of the attached IP network and the CWM map contains the CWM nodes which are displayed directly from CWM via the SvOvTopology daemon. Use the buttons in the Event Manager window to view desired event categories.

---

Performing a Warm Start of CWM

A warm start of CWM consists of stopping the application, then restarting it. When you perform a warm start of CWM, the application continues to use data in the existing Informix database.

---

Caution Performing a warm start of CWM can cause database inconsistencies. If possible, performing a cold start of CWM is recommended over a warm start.

---

To perform a warm start of CWM, complete the following steps:

---

Step 1 From the CWM main menu, enter 2 to select the Stop Core option, then confirm that you want to stop core by responding y to the prompt.

It should take less than a minute for all of the processes and messages to end.

Step 2 Press Return to redisplay the CWM main menu.

---

Note Message retrieval will take approximately 3 minutes to complete.

---

Step 3 From the main menu, enter 1 to select the Start Core option.

Step 4 When the CWM main menu is displayed, enter 3 to launch the CWM Desktop.

---

Performing a Cold Start of CWM

You perform a cold start of CWM when you start the application with an empty database. A cold start is typically used following a CWM upgrade or if there were too many database inconsistencies within the network for a warm start recovery to be successful. You use the create_db command to build a new, empty database. The command create_db destroys any existing data in the database including statistics and object comments.

Cold start options include the following:

•coldstart -F

•coldstart

•coldstartSCM

•coldstartSCM -F

---

Caution Performing a coldstart -F will delete Connection Templates, SCT Templates and Connection Descriptors from the database.

---

To perform a cold start of CWM, complete the following steps:

---

Step 1 At the CWM workstation, enter CWM to display the main menu.

Step 2 From the CWM main menu, enter 2 to select the Stop Core option, then confirm that you want to stop core by responding y to the prompt.

It might take several minutes for all of the processes and messages to end, depending upon the number of nodes in the network.

Step 3 Press Return to redisplay the CWM main menu.

Step 4 From the main menu, enter x to exit the CWM application.

Step 5 At the CWM workstation, enter CWM to redisplay the main menu.

Step 6 From the main menu, enter 1 to select the Start Core option.

Step 7 When the CWM main menu is displayed, enter 3 to launch the CWM Desktop.

Restricted Access Users

For Release 11 of Cisco WAN Manager, a new CWM desktop application, CWM Administration, manages user security. CWM Administration allows restricted access logins to enable users to perform tasks based on detailed access privileges. The user svplus still exists and should be used by experienced and trusted system administrators.

---

Note In earlier releases of Cisco StrataView Plus (release 9.1 and below), the svplus-r account was created when the application was installed on the workstation. The svplus-r account has been removed from CWM starting with release 9.2.

---

CWM Administration provides controlled access through the user's Unix userID and password by customizing user-access profiles. The user access profiles comprise a list of Access Privileges for users for a specific function including:

•ConMgr

•NW Topology

•Image Download

•Node Resync

For each action, a user may be given privileges to read, create, modify or delete functions, or a user may have all privileges to manage all or some actions.

---

Note As in previous releases, only user svplus can start and stop the CWM core processes.

---

Starting HP OpenView

This section describes how to start the HP OpenView application. To start the HP OpenView application, complete the following steps:

---

Step 1 From one of the C-shell windows, launch CWM and start the core processes.

Starting Additional CWM GUIs

---

Note To run multiple Cisco WAN Manager GUIs, you must have a multi-user Wingz license.

---

---

Note It's highly recommended that you use the Web Client to start additional CWM GUIs.

---

More than one workstation can run the CWM GUI simultaneously. To run an additional CWM GUI, complete the following steps:

---

Step 1 Log into a workstation other than the one running the CWM core processes.

Step 2 Enter the following command:

xhost +

This is not necessary if both workstations have the other in its /etc/xhost file as a "+."

Step 3 Do a remote login to the CWM workstation.

rlogin -l login_id hostname

---

Note You can also use the telnet command to connect to the remote host.

---

Step 4 Set the DISPLAY environmental variable by entering the following:

setenv DISPLAY ip_address:0.0

where ip_address is the IP address of the workstation from which you have issued the telnet command.

Step 5 Launch CWM by entering CWM, then select Start Desktop from the main menu.

---

Note CWM core processes running on a workstation can be stopped from any other workstation that is running a remote CWM session. For example, when you log into a workstation running the CWM core processes and select Stop Core (Option 2), you are terminating the CWM core processes for not only yourself, but for all others using those CWM core processes. Therefore, you must be careful not to select the Stop Core option when you are through. Take care to close only the windows you have opened remotely, and at the CWM main menu, select X to exit the application.
