SCSI buses

The SCSI and iSCSI interfaces are found on the front panel. Also on the front panel, Ethernet and Serial ports provide connections for configuration and management of the unit. The LEDs (operation indicators) provide basic status information.

Operation Indicators 1

The TC2201 is equipped with LED indicators for monitoring overall unit status (see

Figure 2 TC2201 LEDs

Chapter 1 Introduction

How the TC2201 Works

• 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 TC2201 detects a fault condition in the TC2201.

• 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 TC2201 Works 1

The TC2201 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.

Processing SCSI Information 1

The following section describes how the TC2201 processes SCSI information when attached to iSCSI hosts. through 5 of the process.

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

command in the iSCSI protocol and sends the packet to the TC2201.

2 The iSCSI controller in the TC2201 receives the packet, interprets the

iSCSI information, and places the packet in buffer memory.

3 The TC2201’s processor interprets the information and programs a

SCSI controller to process the transaction.

Quantum TC2201 User’s Guide 3

Figure 3 illustrates steps 1

Chapter 1 Introduction

TC2201 Benefits

TC2201 Benefits 1

The Quantum TC2201 is designed to connect SCSI devices into an iSCSI network. The Quantum TC2201 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.

Enterprise Class Performance

SAN Management Reduction

Add Intelligence to SCSI Storage

The TC2201 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 TC2201 performs fast tape reads and writes, which enables it to handle larger data sets while completing backup and restore tasks within a smaller time frame.

The Quantum TC2201 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 TC2201 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 TC2201 with simple “point and click” choices on a graphical representation of the TC2201.

The TC2201 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 TC2201 provide customers with a high level of storage functionality for high performance backup and recovery, reliability, security and manageability in their nearline storage solutions.

• 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 TC2201 will retrieve a dynamic IP address from a DHCP server located on the Ethernet network that the TC2201 is connected to. The default setting is Enabled. If DHCP is changed from Disabled to Enabled, it is necessary to reboot the TC2201 before an IP address will be requested from the DHCP server. After the TC2201 finishes rebooting, the QVM session will have to be restarted. The TC2201'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 TC2201. If the DHCP feature is used when there is no DHCP server, the standard for DHCP requires that the TC2201 wait three minutes for a response from a DHCP server before timing out. During this period, the TC2201 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 TC2201. This forces the DHCP server to always provide the same IP address to the TC2201. This setup is useful for remote management of the TC2201 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 TC2201. Access to the Overrides Settings is reserved for authorized Quantum technicians. Selecting the

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

address configured for the TC2201. 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 TC2201 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.

• Primary Initiator ID must be assigned an Initiator ID. This ID should be a unique ID on the bus. The default setting is 7.

• Discovery enables/disables device discovery on this SCSI bus. The default setting is

Enabled.

• Discovery Delay is the time in seconds that the TC2201 waits after a power-up or reboot process (which typically takes approximately 2 minutes) before starting to discover SCSI devices. Quantum recommends you set the value to at least 2 seconds to ensure all SCSI devices complete their individual power-ups. However, the user should be aware this delay is added to the time it takes for the TC2201 to reboot and for QVM to be active again. The default setting is 2 seconds.

• Bus Reset on Boot enables/disables automatic discovery of SCSI devices after an initial power up or reboot of the TC2201. The default setting is

Enabled.

• Override Settings are provided to enhance inter operability with some storage devices that require special consideration during setup of the TC2201. Access to the Overrides Settings is reserved for authorized Quantum technicians. Selecting the

• Sync Negotiation enables/disables the option for synchronous negotiation on the SCSI bus. The default setting is Enabled.

• Alternate Block Size enables/disables block sizes of 520 bytes each, which is the common block size used in AS/400 environments. The default setting is disabled.

• Ultra SCSI 3 Negotiation enables/disables Ultra SCSI 3 support for the selected Target ID. This feature is useful for solving certain compatibility issues in mixed vendor environments, where, for example, there may be a device that cannot handle automatic negotiation of the bus speed, or possibly where there is a device that does negotiate to use Ultra SCSI-3 but somehow cannot actually handle the speed. The default setting is Enabled.

Buffered Tape Writes 2 This Buffered Tape Writes page allows for making configuration changes

SCSI Bus Page

1 Click Buffered Tape Writes from the SCSI Bus menu.

The Buffered Tape Writes page displays (see figure 19):

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 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: If an application requires confirmation of individual blocks

being written to the medium, such as audit trail tapes or log tapes, this option should be disabled.

3Troubleshooting

Various problems can arise when configuring and using the TC2201. This section is provided to help guide the user through some of the basic methods of identifying faults in the setup and configuration of the unit.

Most problems are found in the initial installation. In general, it is wise to check all connections and review the configuration before proceeding with further trouble analysis. Simplify the installation if possible, reducing it to the most basic configuration then adding elements one at a time and verifying the operation at each step.

Indicators 3

The TC2201 is equipped with rear panel LED indicators for monitoring overall unit status (see

Quantum TC2201 User’s Guide 56

figure 44).

Indicators

Power/fault

Ethernet Activity

The LED functionality of the TC2201 is detailed below:

• Power and Fault (Pwr)—This indicator is a bi-color LED. When green,

• iSCSI (Lnk/Act)—When lit green, the upper indicator signifies a good

iSCSI Link Status

iSCSI Activity SCSI Activity for Bus 0 SCSI Activity for Bus 1

this indicator shows that power is currently active. Lack of power indication suggests that the unit is turned off, a problem with the power supplied to the unit, or an internal problem with the unit. When this indicator is amber, this indicator shows that the TC2201 detects a fault condition. Faults can occur as a result of Power On Self Test (POST) failure or operational failures. It is normal for this indicator to flash on when the unit is powered up or reset. If the fault indicator stays lit, contact your product support representative.

iSCSI link on the port. When lit green, the lower indicator signifies iSCSI port activity. If the Link indicator fails to light at all, or if the Activity indicator stays continually lit without corresponding SCSI bus activity, there may be a problem with the iSCSI configuration. Verify the iSCSI configuration.

• SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity on the bus corresponding to the number of the indicator. Activity should be indicated only occur briefly during power up or configuration, and relatively often when the unit is transferring data. If an Activity indicator stays continually lit without corresponding target device activity, there may be a problem with the SCSI bus configuration. Verify the SCSI bus configuration.

• Ethernet (10/100)—When lit, these green indicators signify Ethernet link status and activity. If either of these indicators fail to flicker, or stay continuously lit, there may be a problem with the network connection or configuration. Verify the network connection and configuration. The port must be connected to a 10/100BaseT Ethernet network to function properly.

Chapter 3 Troubleshooting

Basic Verification

Basic Verification 3

Serial Port Problems 3 If you experience trouble communicating with the serial port, verify the

configuration of the host terminal or terminal emulation program. The TC2201 requires the baud rate to be set correctly, 8 data bits, 1 stop bit, and no parity. Flow control should be set to none or XON/XOFF, and may cause problems if set to ‘hardware’. Some terminal programs may not support baud rates higher than 19200, so a lower baud rate may be required. If problems persist, you may want to check the cabling or try a different host. Be sure the Scroll Lock key on the keyboard of the host computer is not enabled. If a valid Ethernet IP address is configured, serial configuration settings can also be set via telnet.

Verify SCSI Bus Configuration

Problems with SCSI bus configuration are common. Basic operation of a SCSI bus can be checked by using the configuration menu to view

attached SCSI devices. Conditions to look for include:

• Termination—Problems with termination can cause intermittent or hard failure. A SCSI bus must be terminated on both ends, and only both ends. Termination issues when both narrow and wide devices are on the same bus are common. Check to make sure that there are no loose terminators. All terminators should be firmly attached.

• Bus Type—The SE and LVD devices can be connected to the same SCSI bus, however on power up, if at least one SE device is detected, the LVD devices must convert to SE mode, and SE mode will be used. Only the LVD interface is being specified for the Fast/40 and higher rates.

• Device ID—Each device on a SCSI bus must have a unique ID. Also check the configured ID’s for the TC2201 to verify these are not in use by other devices on the same SCSI bus.

• Cabling—Check SCSI cables to verify they are functional. SCSI rules for total length, distance between devices, and stub length must be adhered to. Connections should also be checked and reseated if necessary.

Quantum TC2201 User’s Guide 58

Chapter 3 Troubleshooting

Basic Verification

• SCSI Devices—Verify that the SCSI devices on a particular SCSI Bus can be seen in the by the TC2201. Check the Discovery page to verify visibility of devices. If the TC2201 can not see the devices, verify SCSI configuration, cabling, and termination.

Even if the SCSI devices are displayed, they are not accessible unless the mapping mode is auto-assigned or another non-empty map is used.

Verify iSCSI Connection 3 If SCSI devices are recognized on the SCSI buses, but do not appear to the

iSCSI host, it may be that the iSCSI link is not properly established. Most switches have link indicators, showing link status. When the TC2201 is connected and powered-on, this link indicator should show a good link. If it does not, check the cabling or connections. As a means of verifying link integrity when connected to a functional host, disconnecting then reconnecting the Ethernet cable should cause momentary activity of this indicator as the link itself re initializes. Also verify that the media type of the TC2201 and attached switch are of corresponding types.

Verify SCSI Devices in Windows NT

Open the NT Control Panel, select “SCSI Adapters,” and double click on the iSCSI HBA. The SCSI devices should be listed.

If no devices are listed, verify the TC2201 configuration, iSCSI HBA configuration, and cabling.

If devices are listed, verify iSCSI HBA mapping mode and device addresses on the TC2201.

Verify Configuration 3 A number of configuration changes may result in an invalid

configuration. If you are in doubt about the configuration, restore the TC2201 to the factory default configuration and proceed to configure the unit a step at a time, verifying the functionality of the configuration as changes are made.

Verify Mapping 3 Verify that all desired devices have been discovered and mapped. If

using Indexed mapping, try swapping to Auto-assigned to see if this solves the problem.

Quantum TC2201 User’s Guide 59

Chapter 3 Troubleshooting

Basic Verification

Verify Devices 3 It may be useful to connect the SCSI target devices you are attempting to

use to the native SCSI interface to verify that the devices are functional. SCSI target devices can be connected to a host SCSI bus to verify they are functional.

Verify Host Configuration 3 In some cases, it may be that the iSCSI host bus adapter or host device

driver may not be working properly. Check the configuration of these elements. It may be useful to check the release notes for the driver provided to see if there are any specific issues or required configuration. It may also be useful to ensure that you are using a current version of the host bus adapter driver.

Verify HBA Device Driver Information

Check the HBA device driver Readme.txt file for configuration specifics. HBAs typically come with utility programs to view or change their

configurations.

Customer Support 3 If you are unable to resolve an issue, contact your authorized service

representative and ask for customer support (see

“Contacts” on page xix).

After the TC2201 finishes rebooting, the Main Menu will appear on the serial port but, for Telnet, a new session will need to be opened to continue configuring the TC2201. DHCP status can be verified from the Ethernet Configuration Menu where DHCP Configuration is indicated as “Enabled” if DHCP has been successfully activated. Note that the IP address may also appear different than the former non-DHCP IP address.

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

Ethernet network used by the TC2201. If the DHCP feature is used when there is no DHCP server, the standard for DHCP requires that the TC2201 wait three minutes for a response from a DHCP server before timing out.

Your DHCP server may allow you to set up a lease reservation for an IP address by providing the server with the Ethernet MAC address of the TC2201. This sets the DHCP server to always provide the same IP address to the TC2201. This setup can be useful for remote management of the TC2201 via Telnet or Visual Manager. Because the method of setting up a lease reservation varies depending on the DHCP server being used, it is recommended you contact your Network Administrator for assistance.

For more information about configuring DHCP, see Appendix D of this manual.
