3.0 OS SUPPORT
--------------

This application has been tested with Windows NT 4.0 SP6,Windows 2000 SP2.

4.0 COMPONENTS
--------------

SANavigator consists of a Client, Server and a Remote Discovery Connector

You can install SANavigator as a client, a server, both client and server, or
as a Remote Discovery Connector. The major benefit of using the Client/Server
feature is that a SAN running on a server can have a number of clients working
simultaneously on the same SAN. Each client can monitor what all other clients
are doing, whether across the room or halfway around the world. Each client can
access all servers for which it is authorized. Clients can set personal preferences;
preferences are saved locally. You install the Remote Discovery Connector on Host(s)
that you want to In-Band manage remotely. In addition the Host(s) must have the
HBA API library installed


· SANavigator Client: 

This is a Java based GUI application that runs on any Windows NT\W2K system.
It allows you to manage a Server connected to the network

· SANavigator Server: 

This is a Java based application running on a system and providing the
discovery engine and maintenance of the SAN database.
For in-band-discovery, the API library needs to be installed on the server
where the Host Bus Adapters are located.  Out-of-band discovery (through the
network)requires that the SAN be connected to a fabric (either switch or
managed hub).

· SANavigator Remote Discovery Connector: 

This is a Java based application running on a remote host. In previous versions
of the SANavigator application, the SANavigator server could only discover a
network using its internal resources. In version 3.x, you can use the Remote
Discovery Connector (RDC) to pool the resources of other hosts in the network
to perform discovery.

5.0 CONFIGURATION
-----------------

The discovery configuration that SANavigator supports can be divided 
into two types: In-band and Out-of-band (Network).

 5.1 In-Band
If your SAN is directly connected to your FAStT Storage Server or to an
un-managed hub (that is no switch or managed hub is present) only in-band
discovery is possible. In-band discovery takes place on the Server where the
Host Bus Adapters are located. Both the client and the server need to be
installed.

 5.2 Out-of-band (Network)
If your SAN is connected to a fabric (switches and\or managed Hubs network
connected to your server) out-of-band management is required. The SAN 
discovery is done through SNMP communication.
You can have both in-band and out-of-band management of your SAN.
It is recommended that both in-band and out-of-band management be enabled
to get the most benefit of SANavigator's discovery and monitoring capabilities.

8.0. INSTALLING the HBA library
-------------------------------
8.1 When the IBM FAStT HBA driver version 8.1.5.6 and above is installed, the API
     library is automatically installed. Therefore there is no need to install
     the library separately. 
  

9.0. INSTALLING SANavigator
---------------------------
9.1 Before you begin, obtain your network information, including the IP address
    and subnets of SAN switches and servers.

9.2 To install SANavigator on your Windows based computer:
    Unzip the downloaded file and run the Setup.exe file. Follow instructions
    displayed on the screen.

    Note:  If the default directory is chosen, SANavigator will be installed
    into C:\Program Files\SANavigator3.1\

10.0 Starting the SANavigator Server and Client and the Remote Discovery Connector
----------------------------------------------------------------------------------

10.1 Once the application has been installed,you can start it. Launch
    SANavigator by clicking on the desktop icon. This will start both
    the Client and the Server.

10.2 To launch only the client, select SANavigator Client by clicking on
    Start-->Programs-->SANavigator Client. 

10.3 The first time the SANavigator server is started the Welcome Wizard is
      displayed. The Wizard allows you to configure SANavigator. 

   Note: The wizard will request a license key. You may bypass the license key
   entry as it is not required for the base version of SANavigator. The full
   version of SANavigator will be in effect for 30 days. Thereafter the premium
   features will be disabled.  Therefore register your SANavigator application
   in order to get the latest updates and to continue to have access to all
   the powerful features of SANavigator.

10.4  In the General tab of the Discovery dialog (Click Discovery--->Setup),
      select in-band and out-of-band. Make sure Discovery is turned on.

10.5  For in-band, select the IBM FAStT HBA(s) that you want to in-band manage.
     It is recommended that you select all of them to enhance the discovery and
     monitoring of your SAN.

10.6  If you installed the Remote Discovery Connector on a remote Host, launch it
       by clicking on Start-->Programs-->SANavigator Remote Discovery. Although
       the process starts, no user interface is displayed.
     
       Note: to run RDC, the server needs to be configured. Please refer to the 
       online help file or Chapter 25 of the HMM - Setting up SANavigator Remote
       Discovery Connection for in-band management of remote hosts.
 
       Please refer to the online help file or the Problem Determination Maps (PD's)
       for more information. PD's  (now part of the HMM)can be found on the IBM
       Support Web site.

11.0  Uninstalling SANavigator
------------------------------
11.1 Before uninstalling SANavigator, the SANavigator Server needs to be
      terminated. Make sure that no other client is using the server prior to ending
      the process. To terminate the server and client, click Server -> Shutdown
      from the menu bar. A dialog is displayed asking you to confirm the Shutdown
      and whether or not you want to also exit the client. If you do not uncheck the
      "Shutdown Client also" box, both the Client and Server (on the local machine)
      will be terminated provided no other remote clients are running. 

11.2 Uninstall SANavigator by clicking:
      Start button-->Programs-->SANavigator3.1-->Uninstall SANavigator

12.0  LIMITATIONS
-----------------
12.1 Discovery

12.1.1 SANavigator defaults to your local subnet for initial discovery. You
       will need to enter the IP and subnet of the SAN you wish to discover 
       in the Out-of-Band tab of the Discover Setup dialog.

12.1.2 It is more efficient to discover a large subnet by using the broadcast
       method rather than the sweep or individual IP method. The individual IP
       method may be faster when discovering a SAN on a subnet that is congested
       or that has long latencies. 

12.1.3 Verify that there is an Ethernet connection to the SANavigator System 
       and all SAN devices (switches and hubs connections are mandatory) before
       doing a discovery. Otherwise, the message "SAN loaded, no devices present"
       will be displayed.

12.1.4 SANavigator Servers can be managed by remote SANavigator Clients.
       To accomplish this, the Client and Server have to be on the same IP subnet
       address. However, if multiple NICs (Network Interface Cards) are present
       in the system where the SANavigator Server is running, a remote SANAvigator
       Client may not be able to connect to the Server unless the common subnet 
       address is assigned to the first NIC in the Server system. Therefore, when
       you want to manage a SAN from a remote Client ensure that the NIC for the
       local subnet is first in the binding order.
     
12.1.5  In the Discovery Setup dialog box General Tab, you can clear the current 
        SAN. This will remove any configuration that you may have previously set
        up. Therefore, MAKE SURE you export your SAN setup prior to clearing it.

12.1.6  When in-band discovery is enabled, storage devices such as the
        FAStT Storage Servers will be discovered by their IBM machine type
        (3526, 3542, 3552, 1742 etc..). However, if no LUNs are present
        during the in-band discovery, the Storage Servers will be reported
        as Symbios devices or IBM Universal Xport.  This is an indication 
        that the Storage Servers have not yet been configured for use.

12.2 Topology Representation and Display

12.2.1  Changing the color depth of the computer display may cause the window
        to turn black. This occurs when changing color depth and also when
        changing from a high resolution to a lower resolution. If your
        resolution is set at more than 1280 x 1024 pixels, some fields in the
        Port and LUN Performance dialogs are outside the boundary of the dialog.
        Increase the size of the dialog manually and they will display properly.

12.2.2  To obtain the best depiction of bridges and routers and the devices
       connected to them, enter the IP address for each(bridge and router) in
       the individual addresses table on the Out-of-Band tab of the Discover
       Setup dialog. 
       Ensure the Ethernet ports of the bridges\routers are connected to the same 
       subnetwork as the switches and associated Hosts.

12.2.3  Delete off line (red) connections and devices from the topology before
        connecting any new devices to the same port. 

12.2.4  Unidentified devices attached to a supported device may display as a
        Storage or Unknown device. To change the icon to the correct device type,
        right-click on the device,select "Properties," and then select the correct
        device type from the drop-down list.
 
12.2.5  In-band reporting of Configured\Supported speed is valid only for HBAs.
        Ignore the speed reporting for other devices (FAStT Storage Servers
        for ex.)

12.2.6 When in a Fabric environment and in-band only is enabled, the in-band
        discovered devices will be displayed as isolated devices with no
        interconnections.

12.2.7 In version 2.7, SANavigator displayed the SAN topology as one single fabric.
        In version 3.x, each switch and associated devices are shown as an individual
        Fabric. If the switches are connected through ISL (Inter-Switch Link)
        SANavigator will then display the topology as a single fabric and assign
        the WWNN of one the switch to the fabric. 

12.3 General

12.3.1  In-band Management is not functional when the FAStT MSJ Diagnostics and
        Configuration application versions below 2.0 rls 32 is running. Ensure
        that you use FAStT MSJ at version 2.0 Rls 32 or above.

12.3.2  When in-band is enabled, the configured and supported speed of the HBA is 
        displayed in the pop-up device tip. The supported speed refers to the HBA
        speed capability (either 1Gbps or 2Gbps). The configured speed is
        dependent on the link connections (1 or 2Gb). To determine the link speed,
        rely on the HBA device tip information rather than that of a device as
        this information may not be accurate.
