Introduction

This Chapter …

❐ provides a brief overview of the Scalar 218FC Library features. For detailed

specifications, see Appendix F.

With ever changing technology, enterprise storage managers must deal with applications that are increasingly information intensive. At the same time, they are faced with increasing storage demands and shrinking backup windows. To meet these demands, the paradigm of storage routing is being introduced into the Data Center. The need for faster access, distributed resources, greater bandwidth and high availability is creating a convergence of networking and storage media. Fibre Channel technology is one of the most important technological paradigms currently being brought to these problems.

Your ADIC Scalar 218FC Library is a fully automated, high-performance, high-capacity, mass storage system. The Scalar 218FC provides you with unattended, near-line and off-line data storage, archiving, backup, hierarchical storage management (HSM), and retrieval for mid-range and high-end servers and networks.

Your Scalar 218FC Library allows direct inter-connect to the Fibre Channel network. The maximum two DLT™ drives and library can be controlled through a single server, and can also be connected to a FC-AL (Fibre-Channel Arbitrated Loop) interface to allow for independent control of the drives from various workstations. Your Scalar library supports the non-OFC (multi-mode) standard for transmission lengths of up to 500 meters. Your 218FC continues to operate using SCSI-2 compliant protocol over the Fibre Channel interface to achieve high capacity, high throughput, and data compression by incorporating streaming tape drives. Your library can contain up to 18 data cartridges providing a maximum formatted capacity of 1.44 TB and a sustained data transfer rate as high as 1440 MB per minute at an average compression of 2:1 (when equipped with two drives). The tape media, rated at up to 1,000,000 passes and a shelf life of 30 years provides superior media durability and data reliability.

2 Introduction

Features

Direct connection to Fibre Channel networks. Your Scalar 218FC is designed to provide high-speed

data storage and retrieval using SCSI-2 compliant protocol over Fibre Channel networks.

Desktop and Rack-Mounted units. Your Scalar 218FC is the first desktop unit to offer over 1 TB of

data storage. Its attractive case looks great in any office environment. The more utilitarian rack-mounted unit includes all of the features of the desktop unit, but comes equipped with built-in hardware to allow simple installation into standard 19-inch racks.

Multi-function Operator Panel. The Operator Panel, located at the bottom-right corner of the front

panel, employs a 4-line by 20-character liquid crystal display (LCD) and an eight-key keypad to permit you to monitor and control the operations of your library.

Media Picker. The uniquely designed Media Picker is the media cartridge handling mechanism and

normally responds to commands from the application software to move the cartridges between the storage slots and the drives. The Media Picker employs a bi-directional, pass-through gripper that will pick a cartridge from both the front of the picker, or the rear.

Mailbox. The firmware-configurable single-slot mailbox, mounted on the front panel, allows you to

insert and remove cartridges from your library without opening the sliding access panel. When configured with a mailbox slot, there are 17 storage slots available for data cartridges in the Scalar 218FC. This reduces the maximum data capacity to 1.36 TB.

DLT drives. Your Scalar 218FC library is equipped with one or two fourth-generation DLT7000 or

DLT8000 drives. The DLT8000 provides a maximum data cartridge capacity of 80 GB (avg. 2:1 compression) with the DLTtape IV cartridge. The DLT7000 can read and write 2.6 GB, 6.0 GB, and

10.0 GB tape formats, while the DLT8000 can read and write 10.0 GB, 15.0 GB, 20.0 GB, and 35.0 GB tape formats, providing 100% interchange compatibility with earlier DLT drives. You may select tape density through the application software or by pressing a button on the drive.

Barcode Scanner. The Barcode Scanner reads cartridge information contained in a barcode label

attached to each of the data cartridges. This information becomes part of the application software’s library cartridge inventory.

Exabyte® Emulation. To maximize application software compatibility, your ADIC library provides

functional emulation of the Exabyte EXB-480 EXB-480.

System Integrity. A physically lockable sliding access panel on the top of the Scalar 218FC protects

the cartridge slots, drives, and robotics. The application software can enable or disable system security. Additionally, the application software can set a logical system lock.

Maintainability. The transparent window on the front panel allows you to view the full operation of

your library. If a problem occurs, it is both visible and readily correctable. Your library will report any condition that causes a cartridge load or unload to fail, by displaying an appropriate message on the Operator Panel LCD.

Cleaning Cartridge. Although the cleaning cartridge can occupy a cartridge storage slot in the Scalar

218FC (facilitating automated cleaning cycles), you may manually insert a cleaning cartridge through the Mailbox or the sliding access panel.

Manual Cartridge Use. You may easily transport individual cartridges to the drives using the Mailbox

slot, or through the sliding access panel.

™

library and can appear as either a Scalar or an Exabyte

Cartridge Pre-Check. Whenever you power up, your Scalar 218FC maps all cartridge locations. With

barcode scan enabled, the barcode scanner will scan the barcode label on each cartridge and build a log of valid cartridge locations.

Downloadable Firmware. Your Scalar 218FC and the DLT drives employ Flash EEPROM technology.

The library firmware is easily updated using any computer and an associated serial communications application. The drive firmware is updated on-site by loading a firmware update tape (“FUP” tape).

Built-in Diagnostics. Diagnostic firmware tells you when it is time to clean the drive. It also reports

diagnostic results, and drive operating status. Embedded data logging of operational and drive errors can aid you in failure analysis.

12 Getting Started

Chapter

Connecting the Scalar 218FC Library

This Chapter …

❐ provides instructions for physically connecting your Scalar 218FC to your host

system.

❐ steps you through the final phase of the installation process.

Installing the Interface Cables

Follow the steps on the following pages to connect your Scalar 218FC to your host computer and the Fibre Channel bus. This involves installing cables onto the connectors at the rear of the Scalar 218FC. See the section titled: Rear Panel Indicators, Switches and Connectors in Chapter 4 Equipment Description for an illustration showing the positions of the connectors on the rear panel of the Scalar 218FC.

Fibre Channel Connection

Your Scalar 218FC provides support for Multi-Mode Fibre at 1.0625 Gbaud using dual SC connectors:

1. Connect the 3-meter, 50-micron, non-OFC cable (supplied with your Scalar 218FC) between the SC

connectors on the Host Bus Adapter (HBA) installed in your host computer or to a fibre channel hub, and the SC connectors on the rear of the Scalar 218FC. The connectors are keyed to prevent improper installation of the cable.

Fibre Channel Interface Serial Port

The modular jack on the rear panel of your Scalar 218FC provides an RS-232 connection that can be used to configure the fibre channel subsystem, monitor diagnostic status, or update the firmware. To connect the serial cable:

1. Make sure that power is off to the Scalar 218FC.

2. Connect the serial cable plug into the serial connector of the host computer and the modular plug to the

serial port connector of the Scalar 218FC.

10Base-T Ethernet Connection

Your Scalar 218FC supports Ethernet connectivity to provide enhanced configuration capabilities. All functions available through the Fibre Channel Interface Serial Port are available through Ethernet. For example, if you are going to download upgraded firmware using the serial port, you will need to have a copy of the firmware on the host computer hard drive or on a diskette before beginning the procedure. Using Ethernet, however, you can log into a BBS or a world-wide web site and download firmware directly to the Scalar 218FC. If you plan to use the Ethernet capability:

1. Connect an Ethernet cable between your network and the Ethernet connector on the rear panel of the

Scalar 218FC.

Setting the SCSI IDs

Your Scalar 218FC consists of three SCSI devices; the two DLT drives and the library robotics. Each SCSI device in your Scalar 218FC must be set to a unique ID. The ID for the robotics is set by selecting it through the Operator Panel, Off-Line Mode, Configuration Menu, Set SCSI ID option (see sub-subsection titled: Set

SCSI ID, subsection Configuration Menu, section Off-Line Mode Menus in Chapter 4 Equipment Description). Set each drive ID by selecting the appropriate ID number on the switch located on the back of

Chapter

Configuring the Fibre Channel Subsystem

This Chapter …

❐ provides instructions for configuring the fibre channel subsystem of your

Scalar 218FC.

❐ steps you through the final phase of the installation process.

Configuring Your Communications Terminal

The fibre channel subsystem of your Scalar 218FC includes an embedded high-performance 32-bit microprocessor with its own firmware located in Flash EEPROM. The Configuration Program, part of this firmware, allows you to configure the subsystem, monitor subsystem diagnostic results, and download new subsystem firmware. For information on configuring the robotics subsystem of your Scalar 218FC, refer to section titled: Off-Line Mode Menus in Chapter 4 Equipment Description.

This manual and the Configuration Program make references to the “FCR 100” in discussions on fibre channel configuration, monitoring of diagnostic results, and firmware downloading procedures. In these instances, “Scalar 218FC fibre channel subsystem” and “FCR 100” are interchangeable.

To configure the fibre channel subsystem of your Scalar 218FC, to monitor diagnostic results or to download new subsystem firmware, you need to use a host computer application that supports the X-modem data transfer protocol. The following example uses the HyperTerminal application included in Windows NT 4.0. Other applications may use different procedures and com ports, but notice that the baud rate, number of data bits, number of stop bits, whether parity is enabled and what type of flow control to use must be set for your serial communications port as given in this example.

1. Select Programs from the Start Menu by clicking on the Start Button.

2. Select Accessories from the Programs menu.

3. Select HyperTerminal from the Accessories menu.

At the head of the display is the current value of the Fibre Channel-to-SCSI Mapping Mode. The default value is SCSI Controller Command (SCC). There are five possible mapping modes:

SCC— Use the SCSI-3 Controller Command Set (SCC) Logical Unit Addressing method. This mode

requires that the host device driver is capable of addressing a controller device. In this mode, the controller will respond directly to commands issued using the Peripheral Device Addressing Method. Commands addressed using the Logical Unit Addressing Method will be routed to the appropriate SCSI device as specified by the host.

Indexed—provides a user-configurable table that maps FCP LUN values to SCSI devices directly. In

this mode, the controller is not addressable by the host. Configuration allows for sequential FCP LUN values (0, 1, saved in FLASH memory and will persist across power cycles. Various editing assists are provided for creating and modifying this table.

Auto-assigned, LUN priority—Auto assigned mode is similar to indexed mode: a table is used to map

FCP LUN values to SCSI addresses. However, this table is created at power up and does not persist across reboots or power cycles. Discovery is performed on the SCSI bus, and each device is added to the table in the order in which it is discovered.

In LUN priority, as discovery is performed, the LUN value is incremented after the Target value. Therefore, as discovery is performed, all SCSI targets are identified before subsequent LUNs are identified.

Auto-assigned, target ID priority—As discovery is performed, the Target value is incremented after the

LUN. Therefore, all LUNs appear adjacent to the target device in the table.

Auto-assigned bus number priority—This option is not relevant to the configuration of the FCR100,

which has only one bus.

SNMP Configuration

The following section describes the ADIC SNMP Management Information Base (MIB). Many of these definitions are specific to ADIC products and are not currently publicly defined by the IETF (Internet Engineering Task Force) or other public body. General parameters are described for SNMP gets and sets for various functional areas of the Scalar 218FC, and appropriate standards are described.

Several Fibre Channel draft MIB definitions are available for review from:

ftp://ftp.isi.edu/internet-drafts/

ftp.dpt.com/t11/pub/fc/misc./

Your Scalar 218FC currently supports the ADIC private MIB, whose details follow.

Description

The fibre channel subsystem of your Scalar 218FC provides several interfaces, each of which sends and receives data. Management functions are accessible out-of-band via the Ethernet port (10BaseT) that serves as the initial access point for MIB data. The MIB is used to track statistics regarding the flow of data (from Fibre Channel-to-SCSI and vice versa), as well as to allow for configuration changes to be made to the fibre channel subsystem. Possible configuration changes are mostly concerned with the need to change addressing modes depending upon customer needs.

The ADIC private MIB includes all information accessible from the serial user interface. This MIB is included in the fibre channel subsystem firmware installed on your Scalar 218FC.

Interfaces

There are a total of four types of interfaces to the FCR100:

Fibre Channel SCSI Ethernet

32 Configuring the Fibre Channel Subsystem

RS-232 (serial port)

The fibre channel subsystem of your Scalar 218FC is configured as follows:

1 SCSI F/W interface

1 Gigabit Fibre Channel interface (optical)

1 10BaseT Ethernet Port

1 RS-232 Serial Port

The serial and Ethernet ports are used primarily for fibre channel subsystem configuration and management. (TCP/IP requests may also be serviced over the Fibre Channel ports (in-band) in future releases.) A discussion of each of these ports and its associated MIB data follows. Configuration information for each interface is contained in the following section as well.

Fibre Channel

Fibre Channel data reported includes frame and packet information, upper layer protocol (ULP) type (FCP or IP), and other Fibre Channel-specific information. Draft MIBs for Fibre Channel N_Ports and F_Ports are in the public realm.

ADIC proposes to support portions of two standard Fibre Channel MIBs as well as an ADIC private MIB. The ADIC private MIB includes:

Groups for Fibre Channel Configuration FC N_Port Physical Table FC N_Port Statistics SCSI-to-FC Mapping FC-to-SCSI Mapping

SCSI

SCSI is not generally an SNMP managed protocol. The ADIC MIB, however, gathers SCSI information for management purposes. This ADIC specific MIB provides information about the following:

number of I/O operations per bus number of disconnects abort count total data counts in bytes bus resets vital product data from Inquiry command for each SCSI device

This information can be found in the SCSIStatisticsTable and the SCSIProductData Groups of the ADIC private MIB.

Ethernet and Serial Interfaces

The Ethernet interface is used for configuration and management, so total traffic flow is relatively low. The basic Ethernet configuration items are found in the Management Interfaces Table.

The serial port is provided for user configuration. The serial port baud rate will be kept in the Management Interfaces Table.

Trace Dumps

The Trace Dump selection on the Configuration Program menu allows you to perform traces of Scalar 218FC activity for diagnostic purposes. The trace levels defined in Trace Settings Configuration (see above) determine the level of detail displayed. You can perform a trace dump of either the current or previous Scalar 218FC boot cycle (the period of operation between power on or reboot until either the trace dump is performed or the system is powered off). If you encounter problems with your Scalar 218FC, you may be asked by an ADIC Support Engineer to perform the following operation. To perform a Trace Dump:

1. Press 2 on the Configuration Program main menu. This displays the Trace Dump menu.

2. Press 1 to perform a trace dump for the current Scalar 218FC boot cycle, or press 2 to trace the previous

boot cycle. The resulting display will be similar to the following, depending upon the trace levels set during configuration.
