Besides the air-exhaust vents, SCSI and iSCSI interfaces are found on the back panel. Also on the back panel, Ethernet and Serial ports provide connections for configuration and management of the unit. The LEDs (operation indicators) provide basic status information. In addition, a power connector and power switch are located on the back panel along with a Reset Button that is used to manually force a reboot of the TC2201E. For proper operation of the TC2201E, cable connections on the back panel should remain securely in place.

Operation Indicators 1

The TC2201E is equipped with rear panel LED indicators for monitoring overall unit status (see

SCSI Activity for Bus 0 SCSI Activity for Bus 1

The LED functionality of the TC2201E is detailed below:

• Power and Fault (Pwr)—This bi-color LED is green to show that power is currently active and is continuously amber-colored to show that the TC2201E detects a fault condition in the TC2201E.

• iSCSI (Link/Act)—When lit green, the right indicator signifies a good iSCSI link on the port. When lit green, the left indicator signifies iSCSI port activity.

• SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity on the bus corresponding to the number of the indicator.

• Ethernet (Link/Act)—When lit green, the right indicator signifies a good Ethernet link on this management port. When lit green, the left indicator signifies Ethernet port activity on this management port.

How the TC2201E Works 1

The TC2201E is a router that translates the iSCSI protocol to and from the SCSI Protocol—transparently transferring commands, data, and status information—so that devices and hosts can communicate with each other. Interconnection is provided between two SCSI buses and one or two iSCSI networks, also making use of iSCSI’s ability to encapsulate SCSI protocol packets.

Quantum TC2201E User’s Guide 3

Chapter 1 Introduction Processing SCSI Information

Figure 4 shows a host accessing SCSI tape drives and libraries via the

TC2201E.

Figure 4 Example Configuration

Processing SCSI Information 1

The following section describes how the TC2201E processes SCSI information when attached to iSCSI hosts. through 5 of the process.

1 A iSCSI host issues a command. The iSCSI host encapsulates the

command in the iSCSI protocol and sends the packet to the TC2201E.

2 The iSCSI controller in the TC2201E receives the packet, interprets the

iSCSI information, and places the packet in buffer memory.

3 The TC2201E’s processor interprets the information and programs a

SCSI controller to process the transaction.

4 The SCSI controller sends the command to the SCSI device (target). 5 The SCSI target interprets the command and executes it.

Chapter 1 Introduction LAN-free Backup and Restore

LAN-free Backup and Restore 1

LAN-free backup and restore moves the bulk of data backup and recovery traffic from the LAN and onto a dedicated storage network. The TC2201E supports LAN-free backup/restore environments (see

Figure 7 LAN-free backup

figure 7).

TC2201E Features 1

iSCSI Features 1 The TC2201E provides the following iSCSI features:

• Dual iSCSI ports (10/100/1000 baseT Ethernet)

• iSNS support

• Error Recovery Level 0

• Multiple iSCSI connections per session

• VLAN Quality of Service (QoS) support

TC2201E Benefits 1

The Quantum TC2201E is designed to connect SCSI devices into an iSCSI network. The Quantum TC2201E is neatly packaged in a 1U form factor with two 1 Gb/s iSCSI ports and two LVD/SE SCSI buses. SCSI buses automatically negotiate for Fast, Narrow, Wide, and up to Ultra160 SCSI. External throughput is up to 200 MB/s bi-directional per iSCSI port (or 100 MB/s one way per iSCSI port), or up to a total of 400 MB/s bi-directional for both ports.

Quantum TC2201E User’s Guide 7

Chapter 1 Introduction TC2201E Benefits

Enterprise Class Performance

Ease of Use to Reduce SAN Management Costs and Complexity

Add Intelligence to SCSI Storage

The TC2201E offers enterprise class performance with memory buffer bandwidth exceeding 1 Gb/s and delivering end-to-end throughput of up to 400 MB/s bi-directional for both ports (or 200 MB/s each way for both ports together). The TC2201E performs fast tape reads and writes, which enables it to handle larger data sets while completing backup and restore tasks within a smaller timeframe.

The Quantum TC2201E is significantly easier to install than other routers due to the “store-and-forward” configuration feature and the Visual Manager (VM) software. “Store-and-forward” allows configuration files

and TC2201E operational settings to be saved and copied to other like routers, reducing redundant setup tasks. Using VM, service professionals and end users can configure a TC2201E with simple “point and click” choices on a graphical representation of the TC2201E.

The TC2201E has many features that provide intelligence to SCSI devices and help manage SAN configurations, performance and reliability. A short list includes Visual Manager, dynamic storage allocation (i.e. map activation without reboot), SCSI target reset, custom mapping, and access controls (LUN masking and management). These features of the TC2201E provide customers with a high level of storage functionality for high performance backup and recovery, reliability, security and manageability in their nearline storage solutions.

Power Information

Before connecting the TC2201E to other iSCSI devices, it is important to understand the configuration requirements of the environment to which it will be connected. Failure to correctly configure an iSCSI device may impair the operation of the network to which it is attached.

The iSCSI RJ-45 connectors on the unit can be directly connected to a standard 10/100/1000BaseT Ethernet network.

Typical installations will have the TC2201E connected to an Ethernet switch.

Ethernet switches may allow for individual ports to be configured for different media types. The TC2201E must be connected to the switch port with the appropriate Ethernet cabling for both the TC2201E and the switch port to which it is connected.

2 With the TC2201E powered off, connect the TC2201E into the iSCSI

environment using the appropriate cabling. Be sure to insert the cable connectors in the proper orientation.

SCSI Connection 2 The TC2201E can support Fast/Ultra160 Narrow/Wide SCSI, depending

on the specific configuration. The TC2201E is factory configured to support LVD/Single-Ended buses. Two VHDCI 68-pin D-shell, P-type connectors are located on the rear panel of the unit, allowing the unit to be attached at the end of up to two SCSI buses. The TC2201E must always be installed at the end of SCSI buses.

The TC2201E supplies termination power (TERMPWR) to each SCSI bus. An internal self-resetting fuse in the TERMPWR will reset after a fault is cleared.

end being attached to the TC2201E. The type of connector at the other end of the cable will be dependent on the device being connected.

Warning: Please be advised that failure to comply with the

minimum high density cable specifications can result in damage to the TC2201E or an operational failure of the product.

Note: SE is not supported by SCSI-2 protocols. While it is possible to

mix SE and LVD devices on the same bus, doing so may result in substantially decreased performance on the bus.

To connect the TC2201E to a SCSI bus:

1 Power off the SCSI devices on this bus. 2 Connect a SCSI cable to one of the SCSI connectors on the back panel

of the unit. The TC2201E should always be installed at the end of the SCSI bus.

3 Make sure that the bus is terminated correctly. By default, the

TC2201E is automatically terminated. However, the device at the other end of bus must also be terminated.

Ethernet Management Connection

Figure 18 TC2201E Ethernet port

10/100BaseT Ethernet connectivity provides enhanced management and configuration capabilities. The RJ-45 connector on the unit can be directly connected to a standard 10/100BaseT Ethernet network.

If your network does not have a DHCP server, you will need to manually configure an IP address via the serial port using the Command Line Interface (see

appendix C, Using the Command Line Interface).

For more information about the IP network address and the visual management system, refer to the

chapter 3, Quantum Visual Manager.

Note: For manual configuration of the IP address, the TC2201E’s

default IP address is 1.1.1.1 but this is technically not a valid IP address. It is recommended that you change the setting to a valid address, as described in appendix C

Ethernet capabilities include Telnet, FTP, and an HTTP (web browser) support for configuration and management.

Ethernet Management port

RS-232 Serial Management Connection

The 3-pin connector on the back panel of the TC2201E provides a serial port that is compatible with RS-232 signaling levels. The TC2201E is designed to communicate with a terminal or any operating system

utilizing a terminal emulator. The baud rate, data bits, stop bits, parity, and flow control of both the TC2201E and the host system must use the same settings. Refer to

appendix C for more information on serial

management.

Setting Up Serial Port Communications

Leave the TC2201E turned off until you have set up the serial port communications on your host computer, unless serial I/O was previously established and is currently running.

The TC2201E is designed to communicate with a terminal or any operating system utilizing a terminal emulator. For example, Windows 9x, NT 4.0, or Windows 2000 operating systems can use Hyperterminal. Be sure the baud rate, data bits, stop bits, parity, and flow control are set correctly.

To set up serial communications with the TC2201E:

1 Leave power to the TC2201E turned off until you have set up the

serial port communications on your host terminal.

2 Plug the serial cable into one of the host computer’s serial ports

(COM1 or COM2), and then plug the other end of the serial cable into the TC2201E’s serial port

Note: A 3-pin serial cable is included in the shipping container

for the TC2201E.

3 Start the terminal emulator. 4 Set the terminal emulator to use the appropriate COM port.

Note: Auto Detect or VT100 are the recommended settings for

Windows HyperTerminal emulation type.

Note: Before initially powering on the TC2201E, make sure all

the storage devices are powered on first and that they have finished performing their self tests. This will help ensure that device discovery works correctly.

6 Proceed to the following instructions on connecting the power to the

TC2201E.

The power supply used with the TC2201E supports 100 - 240 VAC (Auto Sensing), but the correct type of power cable needed for your installation

should still be verified. The power cable shipped with the TC2201E is a 120 VAC 3-conductor power cable for use in the United States and Canada. This is the power cable that should be used with the TC2201E unless your installation requires otherwise, in which case you should obtain the appropriate power cable as needed.

To connect the power cable to the TC2201E:

1 Connect the female end of the power cable to the power connector on

the back panel of the TC2201E.

2 Plug the male end of the power cable into the power source. 3 Switch on power to the TC2201E using the Power Switch located on

the back panel of the TC2201E.

If accessing the serial port, once you set the baud rate in the terminal emulator, wait until the TC2201E completes the Power-On Self Test (POST) and then the Firmware Initialization process. This can take up

Configuring the TC2201E 2

The TC2201E can be configured in a variety of ways. The following are general procedures for setting up basic operation. Not all of these settings will apply to every environment, but these guidelines should provide the fundamental steps for configuring the TC2201E.

Configuring the TC2201E using the Visual Manager

To configure the TC2201E using the visual manager:

1 While DHCP support is enabled by default on the TC2201E, it is

important to ensure that the Ethernet setting for DHCP is set to Enabled or that a valid IP address and IP gateway have been properly

Quantum TC2201E User’s Guide 25

Chapter 2 Getting Started Configuring the TC2201E

configured for network operation of the TC2201E. Depending on the network environment, it may be possible to use the TC2201E’s default IP address of 1.1.1.1 to configure the unit.

Note: In the event that DHCP is not used, note that the

TC2201E’s default IP address of 1.1.1.1 is technically not a valid IP address. It is recommended that you should change the setting to an IP address that is a valid address (via the serial port using the Command Line Interface). Refer to Using the Command Line Interface

on page 103

for information on configuring the IP address.

2 Verify that the Ethernet and iSCSI ports all have good network

connections. This can be accomplished by issuing a standard “ping” command to the IP addresses for each port. In the event that a port fails to respond, check all cable connections (use new cables where necessary) and be sure there is a good link light showing on the network switch for all connections to the TC2201E.

3 To begin configuration of the TC2201E, enter the IP address of the

Ethernet management port into the web browser address field and press the

Enter key. The home page of the TC2201E should appear. If

not, please verify the IP address or use the Command Line Interface instructions in the next section.

4 In the Home page of the Visual Manager interface, select “Ethernet”

from the Main menu on the left.

5 When the security prompt appears, enter the appropriate user name

and password values and then select the user name is ‘root’ and the default password is ‘password’.

6 The Ethernet page will appear. Select each Ethernet port from the

menu on the left and verify that all Ethernet settings are correct for the network environment that the TC2201E is connected to.

7 Select the Discovery page to verify that all target devices are visible as

expected and that the status for each device appears as expected (i.e. in the “UP” state). If any device is shown in the “DOWN” state, inspect that device. If a device fails to appear at all, make sure the

Submit button. The default

Chapter 2 Getting Started

Configuring the TC2201E

device is powered on and check cable connections. It may be necessary to perform a manual discovery (select

GO button) or to

reboot the TC2201E (menu selection on left).

Note: During reboot, some older browsers will need to be

manually returned to the desired page after the reboot page counter has completed counting down to "0".

8 Select the SCSI Bus page. SCSI ID 7 is the default SCSI Initiator ID for

each of the TC2201E’s SCSI buses. If any devices attached to a TC2201E bus are using SCSI ID 7, then that bus's Initiator ID must be changed. To change a bus's Initiator ID: Select the desired bus from the TC2201E GUI or the SCSI Bus submenu. Then use the Initiator ID field drop-down list to select an unused ID number. Click the Submit button to record the change.

If the TC2201E does not see all of the devices expected, check that the initiator ID(s) are set to a unique value for each bus attached to devices. For any changes, submit those changes and reboot the TC2201E.

Configuring the TC2201D Using the Command Line Interface

You have now successfully configured the TC2201E. This procedure may not apply to all situations but does address most key issues required for initial setup.

To configure the TC2201E from the command line interface:

1 Establish communications over the serial port and then bring up the

Command Line Interface (CLI).

2 In the main menu of the CLI, several menu options should be visible.

Select menu option option

3, “Ethernet”.

1, “Perform Configuration” and then menu

3 To enable remote management capabilities, toggle DHCP to Enabled

or enter a valid IP address and IP gateway, so that the TC2201E is configured properly for network operation. When Ethernet settings are complete, select X to go back to the main configuration menu.

4 Select menu option 5 to access the SCSI Bus menu. SCSI ID 7 is the

default SCSI Initiator ID for each of the TC2201E’s SCSI buses. If any devices attached to a TC2201E bus are using SCSI ID 7, then that bus's Initiator ID must be changed. To change a bus's Initiator ID: Select

Quantum TC2201E User’s Guide 27

Chapter 2 Getting Started Save Backup Version of Configuration

the desired bus by pressing the Enter key. Then use the Edit Initiator Settings menu option to make changes. Select X to return to the Configuration menu.

5 Select the letter A from the Configuration Menu to save your

configuration changes to the TC2201E. Once the TC2201E saves your configuration changes, enter X to exit to the Main menu.

6 Select menu option 2 to access the System Utilities menu. 7 Select menu option 1 to access the System Statistics menu. 8 Select menu option 1 to access the Display Parallel SCSI Protocol

Status menu.

9 Select menu option 2 to access the Display Attached SCSI Devices

menu.

10 Select menu option 4 to display all local SCSI devices. If any device is

shown in the “DOWN” state, inspect that device. If a device fails to appear at all, make sure the device is powered on and check cable connections. It may be necessary to perform a manual discovery (select menu option 1, 2, or 3) or to reboot the TC2201E (from main menu). Select X four times to return to the Configuration menu.

11 Select menu option 4 to reboot the TC2201E. In about 2 minutes, the

TC2201E will once again display the main menu.

12 If the TC2201E does not see all of the devices expected, repeat step 3

above, and check that the initiator ID(s) are set to a unique value for the selected bus. Again, you must save any changes and reboot the TC2201E.

You have now successfully configured the TC2201E. This procedure may not apply to all situations, but does address most key issues required for initial setup.

Save Backup Version of Configuration 2

Once all desired configuration settings are in place, it is recommended to save a backup version of the configuration settings. By doing so, this will help ensure that in the event of a serious problem such as a forgotten user name or password, it will be possible to restore all the settings. For more information, see

Advanced Configuration Options

Advanced Configuration Options 2

The following two sections provide some advanced configuration tips that go beyond the quick setup procedures listed above.

iSCSI Configuration

For iSCSI environments, the TC2201E provides a number of optional configuration settings that can be used to enhance operation and security.

For more information about the settings described in this section, see Chapters 6 and 7 of this manual.

Secure Connections 2

CHAP (Challenge-Handshake Authentication Protocol) provides a secure procedure for connecting to systems, as follows:

1 After a link is made, the TC2201E sends a challenge message to the

connection requestor. The requestor responds with a value obtained by using a one-way hash function.

2 The TC2201E checks the response by comparing it its own calculation

of the expected hash value.

3 If the values match, the authentication is acknowledged; otherwise

the connection is usually terminated.

At any time, the TC2201E can request the connected party to send a new challenge message. CHAP identifiers are changed frequently and authentication can be requested by the TC2201E at any time.

Port Failover 2

The iSCSI Portal Group Settings primarily serve to provide port failover functionality for the TC2201E. By default, the TC2201E is set to use one Portal Group for both ports, which effectively enables failover capability between the two iSCSI ports.However, this option can be disabled so that each port can be mapped separately.

Quantum TC2201E User’s Guide 29

Chapter 2 Getting Started Advanced Configuration Options

Automated Device Discovery 2

iSNS servers maintain information about iSCSI clients and will respond to iSNS protocol queries and requests, and initiate iSNS protocol State Change Notifications. To use iSNS with the TC2201E, simply enable the TC2201E as a client and then enter a DNS name or IP address for up to three iSNS servers.

The default setting is Disabled. When enabled, the TC2201E will function as an iSNS client and will initiate transactions with iSNS servers using the iSNSP. The iSNS client is a process that is co-resident in the TC2201E, and which can register device attribute information with the iSNS server. The capability is used for automated device discovery.

SCSI Configuration

For SCSI devices, the TC2201E provides a number of optional configuration settings that can be used to enhance operation and security.

Buffered Tape Writes 2

Buffered Tape Writes is an option designed to enhance system performance. By returning status on consecutive write commands prior to the tape device receiving data, Buffered Tape Writes remove the latency of waiting for responses from the tape device. In the event that data does not transfer correctly for any reason, the router will return a check condition on a subsequent command.

Commands other than Write(6) are not issued until status is received for any pending write. Also, status is not returned until the device completes the command. For instance, when a synchronizing command is sent to a drive, such as sending a Write File mark, a good status means all prior commands have been successfully completed and data has been successfully written to the medium. This is appropriate for such tasks as file backup/restore.

Note: By default, the Buffered Tape Writes option is disabled. If the

application requires confirmation of individual blocks being written to the medium, such as audit trail tapes or log tapes, this option should be disabled.

Chapter 3 Quantum Visual Manager Accessing Visual Manager

Accessing Visual Manager 3

1 Connect a 10baseT or 100baseT Ethernet cable to the TC2201E. 2 Apply power to any connected SCSI or iSCSI devices. 3 After all attached devices have gone through their power up routines,

boot up the TC2201E.

4 Turn on the host computer. 5 If the IP address for the TC2201E is known, open the computer’s Web

browser and enter the IP address into the Address field. The factory default of the TC2201E has DHCP enabled. To disable DHCP, refer to

appendix C, Using the Command Line Interface for information on

disabling the DHCP option.

Note: For manual IP address configuration, the TC2201E has a

default fixed IP address of 1.1.1.1 but this is technically not a valid IP address. For remote access from WAN or Internet locations, the IP address must be changed to a valid IP address. Valid IP addresses have the form x.x.x.x where each x is an integer in the range of 0 to 255.

If you do not know the IP address of the TC2201E, then connect to the TC2201E using the serial (RS-232) connection (a 3-pin serial cable is included with the TC2201E). Current settings can be viewed and changed from the Ethernet Configuration Menu of the serial interface.

Note: To access the QVM user interface, the TC2201E must be

assigned an IP address.

Note: If the TC2201E is to use a static IP address, the default IP

address 1.1.1.1 should be changed to an address that is appropriate for the IP network it will reside on. Note that the default IP address can be used in a direct connection between the TC2201E and the host computer via a crossover Ethernet cable.

6 Once the host computer's web browser can access the TC2201E,

Quantum Visual Manager (QVM) will display the TC2201E's "Home page" in the browser window. This page provides a high-level snapshot of the TC2201E's status, and is accessible to anyone who knows (and can reach) the TC2201E's IP address. The Report Page is also accessible without needing special access. However, additional TC2201E information, and all TC2201E configuration settings, are user- and password-protected. Selecting other options will cause a login window to appear, where the user can enter a user name and password. The TC2201E defaults are

root for user name and password

for password. This information is required only once per session (described below).

Note: For the QVM interface’s dynamic display of the TC2201E

configuration to be presented properly, use version 6.2 or later of Netscape’s browser on non-Solaris platforms, or Netscape version 6.2.3 for Solaris platforms. If using Internet Explorer, use revision 6.0 or later.

Note: It is recommended to change the user name and password

from the defaults. For more information, see Main Menu

System > User Settings.

7 Upon successful login, the user has initiated a "session", and has full

access to the TC2201E QVM for the duration of the session. A session ends when the user exits all instances of the web browser. Log-in will be required again, via the TC2201E's home page, to initiate a new session.

Note: To end the current session of Visual Manager, it is necessary to

close all instances of the browser window. Merely navigating the browser to another URL is not sufficient to end the current session.

Making Changes via Visual Manager 3

To make changes to settings, use a standard keyboard and mouse to enter new information. Select the Submit button to send changes from the Web browser to the TC2201E. Other than dynamic mapping changes, configuration changes will not take effect until the next time the TC2201E reboots. The unit can be forced to reboot by selecting the Reboot option from the Main Menu.

Detailed instructions about all settings are provided later in this chapter.

Note: It is recommended not to bookmark Visual Manager pages with a

Web browser. Because configuration information is transmitted via URLs, the use of bookmarks could cause the TC2201E to be configured with information present when the bookmark was created. For similar reasons, it is also recommended not to use navigation features of the Web browser (such as the Back or Refresh/ Reload buttons) to navigate Visual Manager.

It is recommended that you navigate only using the Web page links contained in Visual Manager itself. Depending on the Web browser used, these links will often appear as highlighted text. By clicking on these links, Visual Manager can be safely navigated.

When Visual Manager for the TC2201E is accessed, the TC2201E home page appears as follows.

Both the Ethernet management port and the two iSCSI ports can be configured for appropriate Ethernet network settings.

• IP address is the IP address of the TC2201E. The default setting for

the Ethernet port is 1.1.1.1. The default setting for iSCSI Port 0 is

169.254.1.1. The default setting for iSCSI Port 1 is 169.254.1.2.

• Subnet Mask is the IP subnet mask for the TC2201E. The default

setting is 255.255.255.0.

• IP Gateway is the IP address of the gateway for the Ethernet network

connected to the TC2201E. The default setting is 0.0.0.0.

Quantum TC2201E User’s Guide 51

Chapter 3 Quantum Visual Manager Main Menu

• DNS Server IP Address is the IP address for the DNS server and

should be similar in form to XXX.XXX.XXX.XXX where each XXX represents an integer in the range of 1 to 255.

• DNS Domain is the domain name used by the DNS server. For

example, a domain name could appear similar to “server.company.com”.

• DHCP enables/disables support for Dynamic Host Configuration

Protocol (DHCP). When enabled, the TC2201E will retrieve a dynamic IP address from a DHCP server located on the Ethernet network that the TC2201E is connected to. The default setting is Enabled. If DHCP is changed from Disabled to Enabled, it is necessary to reboot the TC2201E before an IP address will be requested from the DHCP server. After the TC2201E finishes rebooting, the QVM session will have to be restarted. The TC2201E's IP address will be different than the former non-DHCP IP address.

Note: To use the DHCP feature, a DHCP server must be operational

on the Ethernet network connected to the TC2201E. If the DHCP feature is used when there is no DHCP server, the standard for DHCP requires that the TC2201E wait three minutes for a response from a DHCP server before timing out. During this period, the TC2201E menus and functions will not be accessible.

A DHCP server may allow the setup of a lease reservation for an IP address if provided with the MAC address of the TC2201E. This forces the DHCP server to always provide the same IP address to the TC2201E. This setup is useful for remote management of the TC2201E via Telnet or Visual Manager. Because the method of setting up a lease reservation varies depending on the DHCP server, it is recommended to contact your Network Administrator for assistance.

• Override Settings are provided to enhance inter operability with some

devices that require special consideration during setup of the TC2201E. Access to the Overrides Settings is reserved for authorized Quantum technicians. Selecting the Go button opens a login prompt for which an authorized technician will have the appropriate user name and password.

• Current MAC address is the current Media Access Control (MAC)

address configured for the TC2201E. The MAC address is a hardware address that uniquely identifies each physical node on an Ethernet network. While the MAC address can be changed, it is highly recommended not to change this address.

• Original Factory MAC address is the MAC address assigned by the

hardware manufacturer to the Ethernet adapter in the hardware. The TC2201E comes initialized with this assigned MAC address.

• Ethernet MTU Size is the Maximum Transmission Unit (MTU) for

Ethernet. This setting can be configured for 1500 or 9000 byte frames. The Ethernet Management port is permanently set to 1500 and cannot be changed. The default setting for the iSCSI ports is also 1500 but a value of 9000 can be configured for jumbo frame support for iSCSI frames.

This page allows for making configuration changes for buffered tape writes.

Buffered Tape Writes can be enabled or disabled. The default setting is

enabled. Buffered Tape Writes is an option designed to enhance system performance. By returning status on consecutive write commands prior to the tape device receiving data, Buffered Tape Writes remove the latency of waiting for responses from the tape device. In the event that data does not transfer correctly for any reason, the router will return a check condition on a subsequent command.Commands other than Write(6) are not issued until status is received for any pending write. Also, status is not returned until the device completes the command. For instance, when a synchronizing command is sent to a drive, such as
