3.1 Target management

Storage devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use the Automatic Target Management feature in the ATTO ExpressNAV interface.

CAUTIONCAUTION

Changing the device map can affect the host’s view of devices and your application configuration

To map Fibre Channel devices, you must connect the devices to one of the iPBridge Fibre Channel ports. To access mapped Fibre Channel devices over Ethernet, you must have a host computer connected to one of the iPBridge Ethernet data ports.

The default is set up as a single target node in which a host or initiator views the iPBridge as a single iSCSI node with all available devices shown as LUNs on a single iSCSI target.

If you decide to change the automatic mapping set up when you powered up the iPBridge, you have two options to map devices after you disable automatic mapping:

• You may map devices manually to the single default node.

• You may map each device to its own target to break the single iSCSI target node into multiple nodes. Multiple target nodes allow greater flexibility to grant or deny access between initiators and devices.

If you divide the default single target node into multiple target nodes, you must set up access to each node separately.

See Exhibit 3.1-1 on page 13 to see the difference between single target node and multiple target nodes.

Target names

Each iSCSI target node accessed through the Ethernet port on an iPBridge is identified by a unique world-wide iSCSI-qualified name. This format references the iPBridge serial number and target node name:

iqn.1995-12.com.attotech:ipbridge: serialnumber <targetname>

Default target node

The default target is set as a single target with Access Control (ACL) disabled and CHAP authentication disabled. The default target node cannot be deleted. The iPBridge maps devices automatically although you can map devices yourself.

Automatically configure a single target

hand side of the screen and drag to the appropriate LUN on the left.

Multiple target nodes

5 Click Submit.

If you are prompted to restart the iPBridge, go to the Firmware Restart page and restart the iPBridge.

Multiple targets allow you to create a more configurable mapping scheme which can segregate storage into different iSCSI nodes within the iPBridge, with each iSCSI target having its own set of access criteria.

For example, if you have two servers and a library with four tapes and a media changer, the default node would provide both servers access to all tapes and the media changer (default target mode).

If you configured multiple target nodes, you are able to map some devices to one server and other devices to the other server, requiring separate user names and passwords for access using various methods including Access Control Lists, iSNS and CHAP authentication. Consult with your network administrator and refer to Exhibit 3.1-1.

Note

If actual storage is mapped to more than one iSCSI target and a server has authorization for both targets, the server could show duplicate storage without any warning to the user.

You may use either of two methods to control access to storage: Access Control Lists or CHAP authentication.

Access Control lists:

each target iqn has its own access control. The iPBridge will check the initiator’s iqn before allowing access.

CHAP to control access:

different CHAP account names and CHAP secrets are assigned to each target.

Automatically configure multiple targets

iSCSI CHAP controls whether CHAP (Challenge Handshake Authentication Protocol) is used for the iSCSI protocol. If CHAP is enabled, the target requires the initiator to negotiate CHAP authentication using CHAP secrets (passwords). An initiator may reject this negotiation.

iSCSI Chap Secret

Specifies the incoming and outgoing secrets (passwords) for iSCSI CHAP sessions. Secrets are case sensitive, 12 to 32 characters (16 for Microsoft iSCSI initiator), and cannot contain spaces. different. An in secret is for authentication of the server to the iPBridge. The iPBridge can store up to 32 in secrets. An

Set up a VLAN: Virtual Local Area Network

A Virtual LAN (VLAN) is a group of devices on the same physical LAN which can communicate with each other as if they were all on different physical LANs. This creates a network that is independent of physical location, allows grouping of users into logical workgroups, increases efficient use of resources, and adds security options by allowing some users into the LAN and keeping other users out.

You may create up to eight Virtual LAN IDs for each Ethernet data port. Each VLAN ID is

assigned a VLAN name of up to 64 characters. If no VLAN Id exists for a data port, VLAN is disabled for that port.

Check Fibre Channel devices

1 Check Fibre Channel device power. Make sure

the devices are powering up.

2 Watch the drive lights before, during, and after

startup.

3 Check cable integrity. Check the cables for

solid connections.

4 If the problem persists, try drives one at a time

with different cables, adding drives and cables until the problem occurs. This helps pinpoint the drive or cable causing the problem.

5 Check with the manufacturer of the device(s)

for further troubleshooting methods.

If Fibre Channel devices appear to be working order, move on to the iPBridge Fibre Channel port section.

Check the iPBridge FC ports

1 Either through the ATTO ExpressNAV or CLI,

check the devices on each port.

If no devices appear, re-check cables. If garbage information appears, the problem is most likely a bad cable.

2 Check the internal cabling of the device. 3 If all devices appear, invoke the FCTargets

command several times on each port to verify that the devices can be seen. If devices appear and disappear, then appear again, the problem is most likely a cable. For information on the FCTargets command, refer to page viii of the Appendix.

FCPortList on

If all devices appear and remain, move to the iPBridge internal configuration section.

When changing any setting on the iPBridge, the configuration must be saved by clicking on the

Save

button on the ATTO ExpressNAV interface

screen or using the

saveConfiguration

CLI command.

Check the serial port

1 Verify you have the correct settings and that

your terminal is configured to:

• Baud rate: 115200

• Data bits: 8

• Stop bits: 1

• Parity: off

• Flow control: None

• Echo: off

2 Verify that your serial cable is less then two

meters in length.

Check iPBridge internal configuration

Verify that the Fibre Channel devices are mapped properly using the ATTO ExpressNAV interface. If devices do not appear, power down the iPBridge and power back on. Refer to

ExpressNAV management

command.

Check iPBridge Ethernet ports

1 Check Ethernet cable integrity. Check the

cables for solid connections. Cat5 cable can cause connection issues with Gigabit Ethernet. Cat5E and Cat6 cable are the best cabling for the iPBridge.

2 Verify the IP address, subnet mask, and

gateway are properly set on each data port on the iPBridge for your network environment. Refer to

3 Verify that the Ethernet speed is set to auto:

check the Ethernet page of the ATTO ExpressNAV interface, or check the LED link lights to determine if the Ethernet speed is correct. Refer to

20.

4 Determine if the iPBridge is set to get its IP

information from a DHCP server. If so, verify that the DHCP server has available IP addresses.

Using ExpressNAV on page 27.

Visually inspect LEDs on page

Page 28

5 Verify that each used Ethernet port on the

iPBridge can be pinged from the desired host. Refer to

If the host cannot ping the iPBridge ports and the iPBridge ports are properly configured, continue to the Local Area Network/Wide Area Network section,

23.

Verify that each port on the iPBridge can ping each desired host. Refer to the Appendix. If the iPBridge cannot ping the host, continue to Check the LAN/WAN on page

23.

6 If using DHCP (the default), verify that the

DHCP server is assigning the correct IP information to the host.

7 Verify VLAN IDs are either disabled or are set

up identically on the iPBridge and the connecting switch.

8 Some older switches/hosts cannot auto

negotiate between the iPBridge and the switch/host at the desired speed. You may have to force the host/switch or the iPBridge to the desired speed.

9 Verify that the host is logging into the iPBridge

correctly by viewing the Connections page and determining if there a “session open” status.

10 Verify that you are using the correct login

procedure for your initiator. For example: When connecting using the Adaptec initiator, the log on screen requests the iPBridge iqn (iSCSI qualified name). If left blank, Adaptec will not be able to log in. Enter “iSCSI” into this field for auto iqn discovery.

command.

Check the LAN/WAN

1 Verify that the switch/switches are segmented

properly so that hosts and the iPBridge have access to each other.

2 If there are routers involved in the setup, make

sure the IP addresses and/or MAC addresses of the iPBridge are allowed through the router.

3 Verify that the switch can see the iPBridge on

the port(s) in question. Refer to your switch vendor’s guide for more information.

Check the iSCSI Host Adapter or NIC

iSCSI host adapters appear as a type of Storage Controller to the host OS, not as a standard NIC. These adapters usually have hardware acceleration to offload the TCP processing from the host. Configuration of these adapters is usually done through the vendor’s own utility and not through the OS itself.

NICs come in two types: accelerated and unaccelerated. Accelerated NICs use some hardware to offload some of the TCP processing from the host. Un-accelerated NICs make the OS do all TCP processing.

To check the iSCSI host adapter or NIC

1 Check cable integrity. Check the cables for

solid connections. Make sure they are plugged in properly. Inspect cable ends for broken clips and improper wiring.

2 Verify that the iSCSI host adapter or NIC is

configured with the correct IP information.

3 If using DHCP, verify that the DHCP server is

assigning the correct IP information to the host.

4 Verify that the hosts are running the

recommended driver and firmware level for the iSCSI host adapter or NIC vendor.

5 Verify that the hosts and the iPBridge Ethernet

port in use are using the same port number to communicate iSCSI. Check the ATTO ExpressNAV iSCSI page. The default port number for all ports on the iPBridge is 3260.

6 Make sure the host adapter/NIC is configured

to log into the iPBridge. Some iSCSI host adapters do not re-login upon reboot or unplug/replug event without marking a check box.

7 Some older switches cannot autonegotiate

between the host and the switch properly. You could have to force the host or switch to the desired speed.

For a NIC using an OS iSCSI driver, continue to the iSCSI OS driver section.

Check the iSCSI OS driver

If the host uses a driver that allows the OS to talk to iSCSI targets via a NIC, not an iSCSI storage adapter:

1 A PC using an iSCSI storage adapter and an

iSCSI OS driver might not work correctly on the

ATTO Technology Inc. iPBridge Installation and Operation Manual

Page 29

same machine. Check with the vendors to make sure they are compatible.

2 Verify that the PC has the latest iSCSI driver as

well as the required service packs and patches. Check with the iSCSI OS driver vendor for more information.

3 Verify that the iSCSI OS driver has started.

Look under Device Manager for Windows or lsmod for Linux.

4 Verify that the iSCSI OS is still looking for the

iPBridge at the right IP address.

5 If using DHCP, verify that the DHCP server is

assigning the correct IP information to the host.

6 Verify that the NIC is configured with the correct

IP information.

7 Verify that the hosts and the iPBridge are using

the same port number to communicate iSCSI on the ATTO ExpressNAV iSCSI page. The default port number for the iPBridge is 3260.

8 Check cable integrity. Check the cables for

solid connections. Make sure they are plugged

in properly. Inspect cable ends for broken clips and improper wiring.

Check the Operating System

1 Verify that the OS has the required service

packs or patches installed. If not, obtain the proper service packs and patches and install them.

2 Some iSCSI host adapters and iSCSI OS

drivers do not always automatically find new targets when plugged in or when forced to rescan. Reboot the hosts.

3 Check if the vendor has a new driver. If so,

install it.

Check the applications

1 Verify that the application is running the latest

device drivers for the devices connected to iPBridge. If not, get the latest device drivers and install them.

2 Verify with the application vendor if the iSCSI

technology is supported on the version of the application being used.

Performance Issues

If the host is not getting the performance it should, check the following items.

Check Fibre Channel devices

Verify that the devices are running at their highest possible speed. Refer to of the Appendix.

Check the iPBridge Ethernet ports

1 Verify that the data port is set to auto negotiate

or forced to 1000 Mb/sec. on the ExpressNAV Ethernet page.

2 Verify that the MTU size is set to optimal setting

for the LAN/WAN environment. 9k frame size is the current optimized frame size for the iPBridge.

3 Verify that the iPBridge TraceLog feature is

disabled. Tracelog tracks certain events that occur in the iPBridge. With this log enabled, performance suffers. Refer to page xii of the Appendix.

FCDataRate

TraceLog on

on page vii

Check the LAN/WAN

1 Verify that the MTU size is set to optimal setting

for the LAN/WAN environment on the ATTO ExpressNAV Ethernet page.

9k frame size is the current optimized frame size for the iPBridge. Many switch and router vendors do not support the larger frame size of 9k or 16k.

2 Verify that each associated port in the IP SAN

is configured for 1000Mbs.

IP SAN traffic should be segmented so that it does not interfere with the main LAN network traffic.For better performance, the IP SAN should be on its own set of hardware.

3 Verify that packets are not being dropped along

the LAN/WAN. Many utilities track packet activity and switch statistics.

Check the Ethernet host adapter or NIC

Ethernet storage adapters generally outperform accelerated NICs and un-accelerated NICs by offloading most of the processing from the host.

An accelerated NIC provides some offloading, but still requires a host OS iSCSI driver, making the host spend more CPU cycles.

Page 30

An un-accelerated NIC does not offload anything so the CPU must do much of the processing.

1 Verify that the adapter or NIC is sent to auto-

negotiate or forced to 1000 Mbs.

2 Set the MTU size to the largest MTU size

supported in the LAN/WAN using the Ethernet page in the ATTO ExpressNAV interface.

9k frame size is the current optimized frame size for the iPBridge. Many switch and router vendors do not support the larger frame size of 9k or 16k.

3 Set the maximum transfer size to the most

efficient size for the intended target(s). For many tape drives, 64k is the optimal setting.

Check applications

Some applications can be configured to change transfer sizes. Configure the application for the optimal size for the particular device(s) connected to the iPBridge.

Check the host system

The faster the host, the faster your transfer times will be. The work flow goes only as fast as the slowest connection in the host system, so transferring data from an IDE drive, 100Mb connection, a DLT 4000, a high speed RAID volume across the country, or other applications, slows the system no matter how fast everything else is in the system.

1 Verify that the iSCSI storage adapter or NIC is

connected to the fastest PCI bus connector supported by the adapter or NIC.

If the adapter supports PCI-X, place the adapter in a PCI-X slot. If one is not available, the host might not achieve the optimal performance capable from the adapter.

Even placing a PCI-X adapter into a 64 bit 66 MHz slot loses performance. Some adapters adjust clock speed depending on the speed of the PCI slot into which they are plugged.

2 The host OS disk and swap disk/partition/file

should be on a high speed drive to minimize the time needed to access the host’s virtual memory.

The more memory a system has, the less time it spends accessing virtual memory (hard drive space).

Check the Operating System

If possible, eliminate swap space and virtual drives which require large amounts of system memory. However, the OS might not allow the elimination of swap space. An OS set to run many kinds of different servers spends much of its CPU cycles on other operations, thus slowing down performance.

Appendix A CLI provides an ASCII-based interface

The command line interface (CLI) uses ASCII commands typed while in CLI mode.

CAUTIONCAUTION

Do not use CLI unless you are directed to by an ATTO technician. Changing parameters may cause loss of data and/or disruption to performance and reliability of

the iPBridge. The ExpressNAV interface is the preferred method to operate and manage the iPBridge. Refer to

Using ExpressNAV

The command line interface (CLI) is a set of ASCII-based commands which perform configuration and diagnostic tasks. Refer to

Interface options

• CLI commands are context sensitive and

generally follow a standard format

[Get|Set] Command [Parameter1|Parameter2]

followed by the return or enter key

• CLI commands are case insensitive: you may

type all upper or all lower case or a mixture.

Upper and lower case in this manual and the

help screen are for clarification only.

• Commands generally have three types of

operation: get, set and immediate.

• The get form returns the value of a parameter or

setting and is an informational command.

• Responses to get commands are followed by

Ready.

on page 33.

on page 27 for details.

• The set form is an action that changes the value of a parameter or configuration setting. It may require a SaveConfiguration command and a restart of the system before it is implemented. The restart can be accomplished as part of the SaveConfiguration command or by using a separate FirmwareRestart command. A number of set commands may be issued before the SaveConfiguration command.

• Responses to set commands are either an error message or Ready. *. The asterisk indicates you must use a SaveConfiguration command to finalize the set command.

• Set commands which do not require a SaveConfiguration command, defined as immediate commands, are immediately executed.

Note

Using certain CLI commands during normal operation can cause a performance drop. Once command actions are complete, performance should return to normal levels.
