Chapter 1: Introduction

This chapter describes the SNC. It provides the followi ng in formation:
•Overview
Configuration Support
Hardware Product Description and Features
Supported Platforms
Supported Devices
Operating Specifications
Introduction to the ADIC Management Console
Features

Overview

The SNC is the interface between storage and Open System Host interfaces and provides Fibre Channel to SC SI connectivity as we ll as the ability to mana ge the library and other devices within the storage network. One possible configuration is illustrated in Figure 1-1.
Introduction
Figure 1-1: Configuration Overview
page 9

Configuration Support

The SNC provides two Fibre Channel interfaces. The FC interfaces are configured with Giga Bit Interface Converter (GBIC) modules. In addition, the SNC has four Ultra2 SCSI interfaces. The Ultra2 interfaces are Low Voltage Differential (LVD). See Figure 1-2:
Figure 1-2: Configuration Detail

Address Mapping

The SNC maps addresses across and between these different interfaces and preserves the persistency of the address maps across power ups of systems, devices, and the SNC. The SNC supports the attachment of up to 2048 unique devices across multiple interfaces.

Interface Protocol Awareness

The SNC processes SCSI-3 and SCSI-2 protoc ols for disk, tape , and tape medium changer devices. It can report the host and devices that are attached to its interfaces. The SNC has the capability to manage the access security between end points on the Fibre Channel interfaces and the SCSI channels.

ADIC Management Console

The ADIC Management Console offers full capability for remote management, configuration, and event notification. Each SNC has internal Event Logging, Event Analysis, and periodic Health Checks for predictive failure analysis. All of these management, configuration, and notification capabilities are accessible via standard SNMP protocol for use with major network management applications. The ADIC Management Console is a value-added software application for remote management and configuration.
page 10
Configuration Support

Access Security Capabilities

The SNC is aware of the hosts and devices that are attached to its interfaces and provides access security between hosts and devices. Access security between different hosts and devices is a requirement for m ulti-initiator SAN solutions. Using the ADIC Management Console you can partition the SAN for different levels of access and performance.
The SNC provides two tools for managing access security: Channel Zoning and Scalar Firewall Manager. Depending upon the unit you have purchased one or both of these options will be available.

Scalar Firewall Manager Option

Scalar Firewall Manager (SFM) technology e nabl es Storage Area Networks with multiple users to share the same connectivity channels or pipes to access the same or different storage elements or resources. Therefore, multiple virtual private connections can be created on the same Storage Networking infrastructure.
SFM is a Virtual Private connection or channel between a storage element and the user of that element in a Storage Area Network. Scalar Firewall Manager is a method of Access Security that manages the access between an Initiator (user, host, system, ..) to Target/ LUN (Device, Disk or Tape, ...) and also protects and preserves such permission.
SFM is completely host independent and requires no software components on the host.
SFM has no interface dependencies and supports Fibre Channel, SCSI or any other SAN interface.
SFM supports SAN connectivity/fan-out products such as hubs and switches.
SFM is independent of the storage elements and requires no change in legacy or new storage devices.
An optional automatic host registration service that sends periodic host status information to SFM is provided.
SFM is an optional software capability for the SNC tha t re quires a license key to be enabled.

Channel Zoning

Channel Zoning is a mean s of managing the access se curity between SAN connections a nd SCSI channels on a channel by channel basis.
Channel Zoning can be used to secure access between a server and its storage, segregating them, for example, from other servers and their respective storage.
The default settings allow all SAN connections to access all SCSI Channels.
Configuration Support
page 11
The Channel Zoning capability is always available to users of the SNC.

Data Mover Module

The SNC can move data directly between storage devices that are attached to it. This direct movement of data can be f rom disk to disk, disk to ta pe , t ape to di sk or t ape t o t ape . The Data Mover Module frees-up valuable system resources on the server and substantially increases the speed of backup and restore operations.
The Data Mover Module is the engi ne for Ser ver-F ree backup and r estore and HSM applications that support the Extended Copy Specification (ANSI T10/99-143r1).
The Data Mover Module capability is always available to users of the SNC.

LED Indicators

The User panel of the SNC provides LEDs t hat i ndicat e the statu s and act ivi ty of t he SNC and its interfaces.
Figure 1-3: LEDs
page 14
Hardware Product Description and Features
When the SNC is first turned on, some of the LEDs will be on and others will flash while it is booting.
The following list brie fly describes how to interpre t the LED signals. See also “POST Error Codes” on page 255.
FC 1-2
For each FC Channel, the LED will be OFF when the Channel is not connected. It will be ON when the Channel is connected to a live Fibre Channel device. It will flash when there is activity on the Channel.
SCSI 1-4
For each SCSI channel, the LED will be OFF when no devices have been detected on the port. It will be ON when a target has been found on the channel. It will flash when there is activity on the channel. The LED will re turn to the OFF state if th e channel is reset.
PWR
•The PWR (Power) LED will be ON when the SNC has power. It will flash if the on-board power sensors determine that any of the required supply voltages are out of range.
RDY
•The RDY (Ready) LED indicates status of Ready. Normally the RDY LED flashes when the SNC has finished booting. If the RDY LED remains ON or OFF for more than a few seconds, it means there is a problem.
•The RDY LED will flash rapidly, 4 times per second, when the SNC is runnin g in diagnostic mode.
ERR
•The ERR (Error) LED indicates that an error condition exists. This may indicate such errors as over-temperature conditions, fan stalled or other internally detected error conditions. See “POST Error Codes” on page 255.

Supported Platforms

The SNC is a platform-independent product. You can connect a host to the SNC after you have installed the appropriate host bus adapter and drivers. You can also connect host systems with different operating systems to the SNC through either SCSI or Fibre Channel.

Supported Devices

Introduction to the ADIC Management Console

The ADIC Management Console uses a combination of industry-stand ard Simple Network Management Protocol (SNMP) requests and a method or techn olo gy known as SCSI over TCP, which encapsulates SCSI commands and/or data in TCP packets.

Client/Server Model

Figure 1-4: Client Server Model
The ADIC Management Console is part of a three-part client/server model.

Agent

Each SNC is a stand-alone, SNMP-manageable host. The ADIC Management Console uses SNMP as the primary method of communication with the agents. This allows you to set and retrieve information that controls the operation of the agent. It also provides alerts (traps) when an event has occurred that requires intervention. The SCSI/TCP component allows you to update firmware on the SNCs and target devices and manipulate device operating parameters. The agent component is embedded in the operating software of the SNC.

Server

The Server component is a Java application that runs on a host computer system (see “Installation Requirements” on page 39). The server is respo nsible for maintaining communication with the managed agents, and acts as an intermediary between the agent running on the SNC and multiple Clients. It provides security features by mainta ining account names and passwords on behalf of the Client application. By keeping track of different Client views, a user can recall a saved view from any Client.
The Server coordinates the requests from multiple clients to manage multiple SNCs. Communication between the Server a nd t he agent s i s carri ed o ut ei th er by SNMP or SCSI/
Introduction to the ADIC Management Console
page 17
TCP, as required. Specifically, the Java Management Application Programming Interface (JMAPI) is used where possible to provide an industry standard and transportable interface. All communication between th e Clients and the Server is i mplemented usin g the Java Remote Method Invocation (RMI), a form of remote procedure call (RPC).
The Server is written to be both transportable and efficient . Multiple Clients can share data the Server already knows about rather than having to request the data again. In addition, the Server receives all traps from the agents and forwards them to the Clients that have registered to receive them.

Client

The Client is a Java application. One or more Clients connect to a Server in order to manage SNCs. The Client operates from any compatible computer, as long as a TCP/IP connection is established to the Server component. This allows for dial-in configurations using Point-to-Point Protocol (PPP), intranet, or Internet access (where allowed by local network policy and firewall configurations). If the client is started on the same host as the server, the connection will automatically be established.
The Client is the application that provides the user interface and allows viewing and manipulating of all SNCs and device parameters. Each Client can be configured by the individual user to show on ly the SNCs of interest. Con s e qu ently, one Client can monitor one set of SNCs and other managers can be responsible for totally different SNCs, without interfering with each other.
For some operations the Client uses Java RMI calls to communicate with the server, and SCSI over TC P to communicate with the SNC.

Features

SNMP

SNMP community strings are a part of the software agent’s messaging functionality that serve to group network devices into logical collections for management purposes. The community strings on the Server must match those on the SNC you wish to manage.
There are three different strings defined for the SNC:
Read for querying the SNC Write for controlling the SNC Trap for receiving event messages from the SNC
The SNC can maintain 32 Read and 32 Write community strings and 1 Trap community s tring.
page 18
Features

SNMP Community Support

A set of commands is provided for manipulating the SNMP Community strings. These strings act as passwords for authenticating requests made from managing applications such as the ADIC Management Console.
There are three different communities defined: Read (allows “Gets” only), Write (allows “Sets”, i.e., changes to be made) and Trap (defines the Community string that a trap recipient will allow). In order for a managing application to view or control an SNMP agent (such as the SNC), it must provide the correct community string for each request. The SNC allows up to 32 community strings for each of the Read and Write communities. There is only a single Trap community string.

Security

Logging on to a serv er is r equired to manage t he SNC via the ADI C Mana gement Conso le application. Two levels of privilege control what type of access is allowed:
Administrator
Allows full access, including changing parameters
User
Allows viewing of data and parameters only
Service Port access is managed with User ac counts cre ated via tel net or the seria l interface on the SNC.

SAN Access Control

Access control features include Channel Zoning and optional Scalar Firewall Manager (SFM).
Channel Zoning allows selected SCSI channels to be available to selected SAN connections.
The SFM option requires a software license key t o enabl e t he Init iator-Target/LUN access control feature. SFM manages access permission between any host attached to an SNC SAN connection and any storage element attached to the SNC. This includes storage devices attached to any SCSI Channel and storage devices attached to any other SAN Connection on the SNC.

Host Registration Service

The Host Registration Service is software that installs on the host from the CD-ROM or it can be downloaded from www.adic.com. It simplifies SFM configuration for the system administrator . It removes the burden of ph ysical ly tr acing each connection to correlate t he HBA World Wide Name (WWN) with a specific host.
The registration service installs on most host platforms and it provides the SNC with periodic host status information including the host name, host type and type of HBA installed. Host information is sent over the host Channel connection to the SNC.
Once installed, the service runs automatically and does not require further system administrator interaction. From the ADIC Manag ement Console, you can see the Channel that the host is connected to and you can tell whether the host is on or offline.

Saved Views

Each user can store their own preferred views on the server. Loading a previous view automatically connects the user to one or more SNCs in a single step rather than specifying connections to SNCs individually. Because they are stored on the server, the same views are available to the user from any client.

Network Discovery

Network discovery allows you to locate any SNC based on network addresses and network masks. This allows management of an SNC without knowi ng the specific Internet Protocol (IP) address beforehand. Alternatively, the IP address (or name, if it can be resolved through DNS) of an SNC can be entered directly for instant access.

Configuration Options

You can set up an SNC with a number of non-default parameters, channel settings, and event management variables. For more informatio n, see the “Controls Menu Gro up” on page 72.

Software Updates

You can update the SNC firmware from the client. For more information, see “Update Firmware” on page 90. You can also send device micro-code to individual target devices as a means to update their firmware using the same method that you use to update SNC firmware.

Features

Event Logging

You can retrieve and view the SNC event logs in a table. Filtering based upon the significance of events simplifies fault isolation. For more information, see “Events” on page 65.

Health Checks

Instantaneous and periodic health checks allow monitoring of each SNC and the devices attached to it. The level and interval of the health check is selectable to obtain greater confidence or minimize the impact on system performance. For more information, see “Health Check” on page 63.

Views

Two different viewing modes are available. Tree View shows all available SNCs and can be expanded to show greater levels of detail.
For more information, see “View Menu Group” on page 55. Figure 1-5 shows the Front Panel vie w, which shows the status of the LED indicators for a
selected SNC.

Other Installation Issues

Host Bus Adapter Setup

Hosts are connected to the SNC through specific Host Bus Adapters (HBAs). The installation procedure varies slightly, depending on which adapter you will be using. The procedure involves these steps:
1. Install the adapter in the host system, following the manufacturer’s recommendations.
2. Power on the host system and update the adapter firmware, if necessary.
Other Installation Issues
3. Boot the operating system and install the device driver for the HBA.
4. Reboot and verify that the device driver has started and that expected target devices are seen by the operating system.
5. Install optional utility so ftwa re, if desired.
Perform steps 4 and 5 after the SNC is installed and connected to the host system.

Installing the SAN Explorer and Host Registration Service

The SAN Explorer software is only available for hosts running the Windows NT or Windows 2000 operating systems. It allows viewing all connected Fibre Channel and SCSI devices. In addition, you can update the code on all devices and view the LUN mapping through switches to which your SNC may be attached. The software also has an option that lets you choose to install the Host Registration Service for the Scalar Firewall Manager.
See the readme file on the CD-ROM for installation instructions. For software updates, visit “Service and Support” at www.adic.com
Installing the Host Registration Service
The Host Registration Service for
Scalar Firewall Manager provides the SNC with periodic
host status inform ation inclu ding th e host name, ho st typ e and H BA. I t is a vaila ble wit hout the SAN Explorer software for host operating systems other than Windows NT or Windows 2000. Host information is sent over the host connection to the SNC. Once installed, the service runs automatically and does not require further system administrator interaction. From the ADIC Management Console, you can see the Fi bre Channel or SCSI port that the host is connected to and you can tell whether the host is on or offline.
The default period is set to send host st atus ever y 15 minutes. I f you want, you can change the period to any v alue between 1 and 255 minutes. See the readm e file on the CD-ROM in the HOSTSW folder for the specific host platform you are using. The readme file contains the installation procedure and information about changing how often host status information is sent.
For Windows NT and Windows 2000: See the readme file in the NT/HOSTSW folder on the CD-ROM. The Host Registration Service installs as part of the SAN Explorer executable. For software updates, visit “Service and Support” at www.adic.com.
For Solaris: A single program is provided for Solaris that runs from the command line or by inclusion in a startup script. Installation is through a Solaris "package". See the readme file in the SOLARIS/HOSTSW folder on the CD-ROM. For software updates, visit “Service and Support” at www.adic.com.

Power-Up and Boot Sequence Guidelines

The SNC scans the SCSI buses after it boots. If you add or remove SCSI devices after the SNC has booted, it will not detect the changes. You can invoke a SCSI rescan or reboot from the ADIC Management Console client or from the service terminal.
Before you turn on or restart the hosts that are connected to the Scalar 100 tape library, you must wait until the SNC has finished booting. You will know that the SNC has finished booting when the RDY LED on the user panel blinks at intervals of one second.
Some operating systems provide you with software methods that allow you to add or remove SCSI devices dynamically after the host has booted. To ensure reliable operation, reboot the host.
If you update SNC firmware you must reboot in order to use the new firmware. To ensure compatibility between the firmware features or functions and the host, reboot the host.
If you update SCSI device firmware, the SAN Explorer application does not display the new firmware version until the SNC has issued a SCSI Inquiry. The SCSI Inquiry occurs when it rescans the SCSI buses. The same is true for the ADIC Management Console client application and the service terminal.

Install the ADIC Management Console Software

The ADIC Management Console allows you to manage multiple SNCs from any location on your network. The system consists of two Java applications. You should install the Server on a single system on yo ur network t o manage multi ple SNCs f rom multip le ADIC Management Console Clients.
This section describes the installation and initial configuration of the Server and Client components. The installation for the ADIC Management Console consists of three components, as described in “Client/Server Model” on page 17. The agent component is provided as part of the operating software already installed on the SNC hardware.
The installation program installs the ap propri ate soft ware co mponen ts on y our Server and Client system. It also installs the required Java Runtime Environment.
page 38
Other Installation Issues
SERVER
The system used for the Server do es not need to be used as a Client and can be placed in a locked closet. It does need networ k access to the SNCs it will be managing, so ap propri ate routes will have to be set on that system and on the SNCs.
CLIENT
The Client system can be located anywhere, as long as it can connect to the Server system using TCP/IP.

Installation Requirements

Minimum configuration guidelines are presented for each system platform in the readme file located in the SANMGMT folder on the CD-ROM. For an updated list of supported platforms and installation instructions, visit “Service and Support” at www.adic.com.

Figure 3-3: Initial Tree View

Tree View

The ADIC Management Console's main screen is made up of two panels, the Tree View panel on the left and the Data Panel on the right. The Tree View in Figure 3-3 is an unexpanded Tree V iew for a single SNC in a single Scalar 1 00 . For an expanded view, see Figure 3-4. Because the SNC wit h IP address 192.16 8.1.182 is sel ected, it i s shown in T r ee View with blue highlighting. Its Name is “SN600007” and its Genre is ”SNC 5101”.
On the right hand side of the screen, at the top of the Data Panel, is a representation of the SNC’s Channel configuration as it appears on the back of the unit.
Product data for t he selected SNC is displayed textually below the Channel configuration graphic.
Near the bottom of the screen, the Up Time for the selected SNC is displayed. Up Time indicates how many hours, minutes and seconds have elapsed since the SNC was last booted.
The area at the very bottom of the screen is used to display status messages. See “View Menu Group” on page 55 for further information.
Tree View
page 45
Tree View is the default view and is selected when the SNC Front Panel option is unchecked. In Tree View, you see icons representing one or more SNCs in a hierarchical tree structure.
When you click the node symbol at the left of the ADIC icon, the tree expands to show connected elements represented by other icons. The ADIC node expands to show channels, and channels expand to show attached hosts and devices. In Tree View, when you click the node sy mbol of an expanded element , its tr ee collapses. Fi gure 3-4 shows the Tree View of an SNC with three tree elements expanded.
page 46
Figure 3-4: Expanded Tree View
Tree View
The icons used in the Tree View carry specific meaning, both in their design and in their color. See Figure 3-5.
Figure 3-5: Icons for Channel Modes and Channel Type
In Figure 3-4, Tr ee View shows Fibre Channel 2 in blue, SCSI Channels 1-4 in green, and Fibre Channel 1 in purple. Blue indicates that the channel is in Target mode. Target is the default mode for Fibre Channels. When channels are set to Target, you are able to see attached hosts, and switches like the Brocade® switch, which broadcasts a World Wide Name, if you are using Scalar Firewall Manager.
Green indicates that the channel is in Initiator mode. Initiator is the default mode for SCSI Chan nels. When chann els are set to Initiator you will be able to see attached devices.
In addition to Target mode and Initiator mode, Fibre Channels can function in Target and Initiator mode. When that is the case, the Fibre Channel icon is purple. Fibre Channel 1 in Figure 3-4 is set to Target and Initiator mode. You will be able to see hosts and devices, as well as cascaded SNCs when a channel is set to Target and Initiator. If there is no node symbol preceding a Channel, as for example Fibre Channel 2 in Figure 3­4, there are no attached elements to display. The ADIC Management Console will not display an icon for a switch that does not broadcast a WWN. The ADIC Management Console displays both SCSI hosts and Fibre Channel hosts that are running the Host Registration Service software.
In Figure 3-4, the SNC is selected. Product information about it appears in the Data Panel, which is in the lower right half of the ADIC Management Console main screen. The information in the Data Panel presents a variety of information, including the unit's WWN, IP Address, Firmware Revision, Serial Number, and Ethernet Speed.

Fibre Channel Port Modes and Connection Options

The Fibre Channel ports support Private and Public Fibre Channe l attachments. Both Loop and Point-to-Point connection options are available. The default Port Mode setting is
Tree View
page 47
Public Target and the default connection setting is Loop. From the ADIC Management Console, you can view the settings and change port parameters.
Port Mode Options
TARGET
In this mode, the port operates as a Target allowing a Fibre Channel Initiator (Host or FC switch) to attach to it.
INITIATOR
In this mode, the port oper ates as an Initiator allowi ng Fibre Channel Targets (disks, tape devices, or FC switch) to attac h to it.
TARGET AND INITIATOR
In this mode, the SNC has access to target devices on the Fibre Channel, and Initiators on the Fibre Channel have access to Targets attached to the SNC. The port operates simultaneously as a Target and Initiator.
PRIVATE
With this option, the SNC scans the local loop for devices but does not check for Fabric devices. You can select this option if you are connecting target devices directly to the port .
PUBLIC
With this option, the SNC scans the loop for Fabric devices. If it finds a Fabric device, it logs-in and queries the Name Server for tar get devices t hat are available o n the Fabric. If it finds Targets attached to the Fabric, it adds all of them to the device map. You can select this option if you are conne cting a Fibr e Channe l switch t o the port and you wan t the SNC to have access to all of the available target devices attached to the switch. Otherwise, if target devices a re co nnect ed di rect l y to t he port , i t a utomat ica lly switches to Private mode.
Connection Type Options
LOOP
With this connection option, the port operates with attached loop-capable devices. If a point-to-point device is attached, the SNC will not be able to communic ate with it.
POINT-TO-POINT
With this connection option, the port supports point-to-point fabric connection (F_Port Login). It also operates in “old port mode” for compatibility with N_Port devices that do not support Loop. If loop-capable devices are attached, the SNC will not be able to communicate with them.

Tree View
When a host is selected, information about its WWN, Network Name, Operating System and HBA attachment is all included in the lower portion of the Data Panel . See Figure 3-9.
Figure 3-9: Information About a Selected Host
No matter what component in Tree View is selected--host, channel, device, or the SNC itself--the top "paragraph" of the Data Panel states the IP address, Name, WWN, and Firmware revision level of the current SNC.
Some information that is presented in the Tree View panel is also presented in the Data Panel. For example, both Tree View and the Data Panel display the Channel Number, Target ID, Device LUN and Assigned LUN of a device. A LUN (Logical Unit Number) is a 3-bit identifier used on a SCSI bus to distingui sh between u p to eight devices wit h the same SCSI ID. Tree View graphically specifies the device type. The Data Panel displays textual information about the Vendor ID, Product ID, Serial Number, as well as other information about the size and capacity of the device.
At the top of the Data Panel there is a graphic showing the front of the SNC. In Figure 3-8 on page 50 for example, the slot where the selected device attaches is show n in green. The slot is connected by a black line to an icon appropriat e to the device being represen ted. For FC-connected hosts, the slot is connected by an orange line to an icon representing the Host. See Figure 3-9 on page 51. Note that when the Channel itself is selected neither the Host nor the device icon appears in the SNC front view graphic.

File Menu Group

The File Menu Group offers commands for loadin g, manipula ting, and saving v iew files. See Figure 3-10.
Figure 3-10: File Menu
A view file is a list of SNCs viewed at any one given time. Each user can save preferred views on the server. Loading a previous view automatically connects the user to one or more SNCs in a single step rather than specifying connections to them individually. Because they are stored on the server, the same views are available to the user from any client.
You can have many views. At the beginning of a session, you can choose to load a view from the Open a Previous View menu, which displays all the views tha t y ou sa ved previously (for your logon account only) so that you can recall an earlier viewing environment.
page 52

Save Current View

A view is defined by the current collection being viewed. For this option to be available (not grayed-out), the current view name must be known either from a previous loading or a Save Current View as o peratio n. F or ex ampl e, if you i nitial l y load a vi ew t hat i ncl ud es the SNCs in Scalar 100s that are being used to store data for Floor 2, Floor 3, and Basement, and then during the course of the session decide to disconnect from the SNC handling Floor 2’s storage, performing a Save Current View only saves a view of the SNCs handling storage connections for the Floor 3 and Basement Scalar 100s. The original view is overwritten by the new view. If you did not perform a Save Current View, the ori ginal view of the thr ee SNCs managing F loor 2, Fl oor 3, and Basement SANs is still valid for the next t im e that view is loaded.

Tools Menu Group

The Tools Menu Group provides options for finding and connecting to SNCs and controlling SNC status reports.
Figure 3-24: Tools Menu

Discover Net

With Discover Net, you can discover all SNCs on the network. When you select this option, you are prompted to enter the Network Address and the Network Mask. See Figure 3-25. These parameters tell the ADIC Management Console which subnet addresses to check.
Figure 3-25: Discover Net
page 60
Tools Menu Group
In the Network Address box enter “0” in the place o f the subnet you wish to explore, e.g. the entry “192.168.22.0” searches for IP addresses between “192.168.22.0” and “192.168.22.255”.
In the Network Mask box enter a subnet mask that matches the class of network you are searching, e.g. for a Network Address entry of “192.168.30.0” leave the default entry “255.255.255.0” as the Network Mask. For a Network Address entry of “192.168.0.0” change the Network Mask to “255.255.0.0”.
You must enter a Timeout value in milliseconds to limit how long to wait for a response from each IP address that is checked. You may set the Timeout value considerably lower than the default (1000 milliseconds) in order to speed discovery. Before starting the discovery process, you are given an estimate of how long the discovery will take and you have an opportunity to abort the process or continue. The default Timeout value is intentionally set to a high number in order to make certain that all devices on a slow network are discovered.
When the discovery is finished, each SNC that was found is displayed in the tree. The collection displayed defines the cu rrent vie w. If a view was already loaded, the new SNCs that were discovered become part of that view only if you perform a Save Current View. T o create a new view with a different name, perform a Save Current View As. See Figure 3-11 on page 53.

Connect

If you want to connect to a specific unit via its SNC you are prompted t o enter it s name or IP address. See Figure 3-26. To use a name, the name must be resolvable to an IP address by the server system. Contac t your networ k administra tor for assist ance. If found, the SNC is added to the tree display. If a view was already loaded, the new SNC becomes part of that view only if you perform a Save Current View. To create a new view with a different name, perform a Save Current View as. See Figure 3-11 on page 53.

Set Event Trap Threshold displays the list of the events and their current trap threshold
level settings for the sele cted SNC. The Trap Threshold Level deter mines how many times the event can occur before a trap is issued which sends a message to all users monitoring the SNC. See Figure 3-38. If you have administrator privilege s, you can modify a threshold level by selecting an event (clicking on it), and then pressing the Change button. See Figure 3-39. You are then prompted to enter a new value for the Trap Threshold Level.
Attention: Do not change trap thresholds unless recommended by your service representative.
page 67
Figure 3-38: E vent Trap Thresholds
A threshold level of zero disables traps for that event. A threshold level of one mean s that a trap is sent each time the event occurs. Any other value (up to 255) specifies how many times the event can occur in a ten-minute period; that is, the specified number of events
page 68
Tools Menu Group
must occur within a ten-minute period or no trap will be issued. The Fibre Channel LIP is the only event that has its threshold level set to something other than 1.
Figure 3-39: Change Event Threshold Dialog Box
Receive Event Traps is the last option on the Events submenu. It controls whether your
ADIC Management Console client receives trap notifications for the SNCs you are monitoring in your current view. By default, event traps are enabled (indicated by the check mark). Select this option to disable receiving traps (the check mark will be removed).
Tools Menu Group
When a trap is received, the symbol is displayed in the status/message area on the bottom of the main screen. You can look in the Received Event Traps window to see the trap message. The message identifies the SNC by its IP address. It includes a date and time stamp, an event code and a description of the event that caused the trap.
Figure 3-40 is an example of the Event Traps window. The Event Traps window is a separate window that is always present when the ADIC Management Console application
page 69
is connected to a server. You can Minimize the window but you cannot close it. You can double-click on an event in the window to display more detailed information.
Figure 3-40: Event Trap Window
In the example above, the Event Trap window contains some typical Healt h Check events. You can see, for example, that the server at 192.168.30.200 was not online on August 2, 2001 at 4:46 p.m. (“failed heartbeat occurred”), but that it came back up (“revived heartbeat occurred”) at 5:15. For more information, see “Remote Events and Notifications” on page 92.

Save SNC 5101 Configuration

Save SNC 5101Configuration copies vital configuration information from the selected
SNC to a file on the ADIC Management Console server or to a file and location you specify in the browser dialog. Files that are saved when this opt i on are cho sen i nclude t he device map, Fibre Channel and SCSI port settings, Scalar Firewall Manager settings and Channel Zoning settings. Figure 3-41 shows the Save ADIC SNC Configuration dialog.
Figure 3-41: Saving a Configuration

Use this menu if you want to enable the SFM or the Da ta Mover Module for the selected SNC. If these features are already enabled or unavailable they will be grayed out on the menu.
Figure 3-46: Enabling Optional Features

Feature Enable: Scalar Firewall Manager

Scalar Firewall Manager allows you to control access permission between FC hosts (HBAs) and storage devices (T arge t LUNs) attached to the SNC. If you need to enable this feature, you must have the License Key that corresponds to the serial number of your SNC. If the feature has been factory-enabled, you can just type enable.
When you choose this menu item you are presented with the dialog box shown in Figur e 3-
47.
Figure 3-47: Enter License Key to Enable SFM
Controls Menu Group
Attention: When you enable SFM, it takes full control of the SAN connections. By default, SFM inherits access permissions for hosts that are currently attached and online. If you ad d a host to a SAN connection the new host will not have access to any LUNs until you assign L UNs to it. Please se e “Scalar Firewall Manager” on page 99 before enabling SFM.
Note: If this feature is factory enabled, yo u can act ivat e it by si mply en tering the word enable rather than an actual license key.

Controls Menu Group
See Figure 3-49. Channe l Zoni ng is the fifth option on the right-click menu. Channel Zoning does not need to be Enabled before you use it.
Figure 3-49: Right-Click Menu: Channel Zoning
Channel or “Port” zoning configures access to all the LUNs on a particular SCSI channel for the exclusive use of a host or group of hosts on a single Fibre Channel. In a situation where the SCSI devices are tape devices and more than one host is connected to the Fibre Channel, the tape appli cation’s software will typically manage ho st requests to the zoned SCSI Channel. Channel Zoning permits or denies access to an entire Channel (and every device on that Channel) for the selected host(s).
Channel Zoning allows you to configure zones to restrict access between SAN connections and SCSI Channels. The defau lt settings allow all SAN connections to acce ss all SCSI Channels.
When you select this menu option, a dialog box displays the current Channel Zoning settings. If you have administrator privile ges, you can change the settings. Figure 3-50
Controls Menu Group
page 75
shows the default settings for an SNC. Refer to “L ib rary and Controller Cabling to Drives” on page 28.
Figure 3-50: Default Channel Zoning Settings
Remove check marks in the boxes to create restricted access zones for the desired SAN connections and SCSI Channels. All combinations are possible. Bear in mind that an entire channel is zoned when the box is clicked.
Attention: If you make changes to the Channel Zoning settings you must reboot the SNC for the new settings to take effect.

Access Options: Scalar Firewall Manager

Scalar Firewall Manager provides you with a finer degree of access control between host bus adapters in individual systems and Target LUNS on storage devices. SFM can be used to allow multiple Fibre Channel hosts connected directly or via switches and hubs to be able to share the same SCSI or Fibre Channels while restricting their access to selected LUNs.
Once you have Enabled Scalar Firewall Manager, you can open the Scalar Firewall Manager settings box by selecting the SNC in Tree View, and then going to Controls > Access Options >Scalar Firewall Manager. You may also choose to use the right-click

Bus Reset on Power Up is typically enabled. Removing the check mark from this box disables SCSI bus reset on power-up.
Enable Termination is typically enabled. Removing the check mark from this box disables the internal termination circuits.
The default Alternate Initiator ID is set automatically by the SNC. When the SNC scans the SCSI Bus, it determines which IDs are currently being used by target devices and sets the Alternate ID to the highest ID not in use. You can change the Alternate ID using the pull-down or typing a new number. To restore the automatic default selectio n, choose “-1” from the drop down list. This o ption is grayed out when the SCSI channel is being se t to Target Mode.
You can press the Rescan SCSI Bus button to rescan the SCSI bus so the SNC can discover devices that have been added or removed. It also refreshes the data for the devices on the SCSI channel and updates the display.
Pressing the Reset button reinitializes the SCSI Channel. This will cause the SNC to abort all pending commands, reset the channel, and perform a rescan.
Attention: Use Reset carefully because it causes pending I/O commands to return failed status back to the host operating system and may have unexpected results. Make sure all I/O is stopped before issuing this command.
Attention: when a SCSI channel is changed from Target to Initiator mode, the values that appear in the Host Id and Alternate Host Id combo boxes do not default to 0. They default to values that the SNC has most recently used.
When you are finished viewing or setting SCSI Channel parameters, you may press Cancel to abort all changes and return to the main screen or you may press OK to keep your changes and return to t he main screen.

Host Type has twelve possible valu es: AIX, AS400, Gateway, ADIC SNC, HP-UX, Linux, NT (includes Windows 2000), Netware, Generic, Solaris, Autosense/NT or Dell PV-136T-FC. Hosts running other operating systems use the setting Generic.
Choosing Linux sets the d efault setting to the Sola ris host type. The default setting is NT. The host type is either the name of the host Operating System or the type of appliance attached to the port. This setting controls the way the SNC translates SCSI commands, such as the format of SCSI sense data, which needs to be presented differently for some hosts. If the SFM option is enable d, the host type setting in the SFM control panel will be used rather than this setting .

The default Loop ID setti ng is Soft and should typically not be changed. (It may be appropriate to use another Loop ID setting when using Fibre Channel switches). If you remove the check mark from the box, you can enter a loop ID value from 0 to 125.
Frame Size has three possible values: 5 12, 1024, and 2048. The Fibre Channel frame si ze is specified by each receiving node and need not match any other node. The frame size should typically be set to 2048. (It may be appr opriate to us e another frame size if required by a particular software application.)
Figure 3-59: Fibre Channel Default Settings
Figure 3-59 shows the default Port Mode setting for the QLogic ISP2300 Fibre Channel interface controller. You have options for changing the port mode and connection. For more information on default modes, see the discussion following “Fibre Channel Port Modes and Connection Options” on page 47.
When you are finished viewing or setting Fibre Channel parameters, you can press the Reset button to make your changes take effect immediately. If you press the OK button, you will be reminded that a Reset or Reboot are required for the changes to take effect. Press OK to keep your changes and return to the main screen. Press Cancel to abort your changes and return to the main screen.

Device Mapping

Using the ADIC Management Console, you can edit the SNC’s persistent address map database and customize the LUN assignment for each target device. Select the SNC in Tree View and then select Device Mapping from the Controls pull-down menu. You may also access the Device Mapping dialog box via the right-click menu. See Figure 3-60.
Device Mapping is the third choice from the bottom.
Figure 3-60: Right-Click Menu: Device Mapping
Attention: Making changes to LUN assignments in the persistent address
map database can affect
Scalar Firewall Manager access settings. If you assign
different LUNs to devices that were under SFM access control, the same LUN could become associated with different devi ces and data would be lost. After you have finished editing the d evice map, yo u must reboot the SNC for any changes to take effect.

Figure 3-61: Devices Available for Mapping
In Figure 3-61, several SCSI devices are displayed, one of which is on SCSI Channel 4 of the SNC at 192.168.1.182. The Target ID of the selected tape device is 4, its Device LUN is 0, and its Assigned LUN is 10. The Da ta Panel uses textual label s to specify this information. Tree View uses the format [Target ID:Device LUN] - Assigned LUN. The Assigned LUN is the LUN number that the SNC has assigned to this device in its persistent device map.

Figure 3-62: Device Mapping Window
As shown in Figure 3-62, devices t hat ha ve already been ente red i nto th e persi stent d evice map appear in black type on the left. The Device Mapping Window uses the format Channel [Target ID:Device LUN] after the Channel type, SCSI or Fibre. The assigned LUN for each device shows up only in t he left-most column of the window, labeled 'LUN.' Grayed-out images of these same devices, without the Assigned LUNs, appear in the right-hand column. LUN 0 is typical ly occupi ed by the SNC Command and C ontrol L UN, unless it has been assigned to another LUN.
In order to assign devic es to approp riate LUNs, you may drag and drop de vices in two different ways. You may move devices back and forth from col umn to colu mn or you may move them verticall y within the left-hand co lumn to different LUNs.
If a device that appears in the Available LUN column is not already assigned, you may delete it by dragging it down to the recycle bin icon.
In Figure 3-63, LUN 0 is still occupied by the SNC C ommand and Control LUN. However, one of the SCSI devices on SCSI 4 has been assigned a lower Assigned LUN
