Windows users continue to Installing MS iSCSI Initiator for Windows; Mac users continue to Installing iSCSI Initiator for Mac OS X. If you use Internet Explorer, use Setting up Internet Explorer if needed. Installing MS iSCSI Initiator for Windows 1 2 3 4 5 6 7 8 9 10 11 12 13 Download the latest version of Microsoft® iSCSI Software Initiator from www.microsoft.com/downloads. Searching on iSCSI Initiator usually helps to locate it. Launch the Initiator installation program and follow the instructions.
3 Configure the iPBridge To configure the ATTO iPBridge, use ATTO ExpressNAV. Default values are appropriate for most configurations, but may be modified. The ExpressWizard simplifies initial configuration of the iPBridge. Default values are appropriate for most applications. If you wish to change these values, use ATTO ExpressNAV, a browser-based graphical interface. Other methods are also available. Refer to Interface options on page 23.
9 Select the answer to the question Does your network support Jumbo Frames? 10 Click Next. 11 Data port IP address, subnet mask and gateway information is listed. Change any elements as needed. 12 Click Next. 13 The configuration for the iPBridge based on your input in the previous screens appears. If the information is correct, click Commit. 14 The ExpressWizard configures your iPBridge and storage.
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. CAUTION • Changing the device map can affect the host’s view of devices and your application configuration. To map SCSI devices, you must connect the devices to the iPBridge SCSI port.
Multiple target nodes 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).
Exhibit 3.1-1 Target node configurations. 11 ATTO Technology Inc.
3.2 iSCSI configuration You may fine-tune the iPBridge using the ATTO ExpressNAV interface. Several special iPBridge features may be accessed using the ExpressNAV graphical user interface.
3.3 Optional changes Default values, even if you have not used the ExpressWizard, are appropriate for most configurations, but may be modified. Preliminary steps 1 If you are not already in the ExpressNAV interface, type the IP address of your iPBridge in a standard browser as found in Using ExpressNAV on page 23, click Enter Here, 2 Modify passwords 1 2 Follow the Preliminary steps Click Bridge. The Bridge Configuration page is displayed. 3 4 5 6 type in your user name and password, and click OK.
Enhance performance Note If you used ExpressWizard to set up your iPBridge, changing these parameters may interfere with ExpressWizard settings. Default values, even if you have not used the ExpressWizard, are appropriate for most configurations, but may be modified. 1 2 3 Follow the Preliminary steps. On the iSCSI page, enable SpeedWrite. On the Ethernet page, change MTU to 9014.
4 Remote system monitoring You may set up the iPBridge to send notifications when certain events occur. You may set up the iPBridge to send notifications when certain events occur using the Remote Management page of the ExpressNAV interface. You designate the person receiving notification of conditions and the level of severity which prompt notification using the Simple Network Management Protocol (SNMP). For both methods, the severity level which is report can be critical, warning or all.
5 Updating firmware Several processors control the flow of data in the ATTO iPBridge. The firmware to control these processors can easily be upgraded in the field. The iPBridge firmware is distributed as an .ima file can be obtained from the ATTO Technology, Inc. web site at www.attotech.com or from the CD included with your iPBridge. CAUTION Using ATTO ExpressNAV 1 2 3 Before beginning this procedure, ensure that all I/O to the iPBridge has stopped.
6 Troubleshooting If it is clear that a particular component system is at fault in a problem situation, go directly to that component. If it is not clear, the best approach is to troubleshoot using the inside-out method. You may check on the status of your iPBridge using the ExpressNAV interface.
platforms and host adapters, visit www.attotech.com. Check iPBridge product versions For a current list of required updates, visit www.attotech.com. 1 2 3 If you have not already, open an ExpressNAV session. Go to the Status page and check the version number. If you need to update, download the update from www.attotech.com. Refer to Updating firmware on page 16. Check components Check SCSI devices 1 2 3 4 5 6 7 Check SCSI devices to make sure they are all set to different SCSI IDs.
Check the iPBridge Ethernet port 1 2 3 4 5 Check Ethernet cable integrity. Check the cables for solid connections. Cat5 cable can cause connection issues with Gigabit Ethernet. Cat6 cable is the best cabling for the iPBridge. Verify the IP address, subnet mask, and gateway are properly set on each data port on the iPBridge for your network environment. Refer to Installation on page 5.
Some older switches cannot autonegotiate between the host and the switch properly. You may have to force the host or switch to the desired speed. 7 For a NIC using an OS iSCSI driver, continue to the iSCSI OS driver section. 8 7 Check the iSCSI OS driver This section is for hosts using a driver that allows the OS to talk to iSCSI targets via a NIC, not an iSCSI storage adapter. 1 2 3 4 5 6 A PC using an iSCSI storage adapter and an iSCSI OS driver might not work correctly on the same machine.
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.
MaxBurstLength The maximum SCSI data payload, in bytes, in a Data-In or a solicited Data-Out iSCSI sequence. A sequence consists of one or more consecutive Data-In or Data-Out PDUs that end with a Data-In or Data-Out PDU with the F bit set to one. Tcp1323Opts This parameter controls RFC 1323 time stamps and window-scaling options. Time stamps and window scaling are enabled by default, but can be manipulated with flag bits. Bit 0 controls window scaling and bit 1 controls time stamps.
7 Interface options Alternative methods to the ATTO ExpressNAV interface may be used to manage the iPBridge. ATTO ExpressNAV is the recommended interface. Using ExpressNAV Each page in the ATTO ExpressNAV interface provides information and/or configuration parameters based on a specific topic. ATTO ExpressNAV is the recommended management tool for the iPBridge.
5 6 only displayed at start-up. The last line in the start-up message sequence is Ready. In serial port sessions, there is no prompt on the line below the word Ready. Begin typing commands in the blank line where the cursor is resting. No user name or password is required for serial port access. To verify that you have connected successfully, type help after the Ready prompt and press Enter.
Appendix A Cabling Additional information to physically connect ports to devices and to your SAN. SCSI cabling Examples The SCSI specification limits total bus cable length for single-ended SCSI in a non-UltraSCSI environment to 3 meters (combined length of both internal and external cable lengths). In an UltraSCSI workgroup environment with a 7drive tower, you are limited to 1.5 meters between the host and the tower, including the cabling for the tower.
Connecting SCSI devices to the SCSI port ATTO iPBridge SCSI ports connect SCSI storage devices to the network. The SCSI port is a bus capable of supporting 15 devices and each bus is capable of 40, 80, 160 or 320 MB/sec. (Ultra, Ultra2 or Ultra320) transfer rates. The iPBridge supports a wide variety of SCSI storage devices including stand-alone drives, removable drives, JBODs, RAIDs, tape, CD and DVD drives, changers and libraries.
Appendix B CLI provides an ASCII-based interface The command line interface (CLI) uses ASCII commands typed while in CLI mode. CAUTION 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 Interface options on page 23 for details.

Access to the target node is keyed to the iSCSI qualified name of listed initiators. Note AccessControl cannot be used with iSNS.
Date Regulates the current date for this iPBridge. The date range is 1/1/2000 to 12/31/2099. set Date [MM] / [DD] / [YYYY] get Date DeleteAllMaps Removes all mapped devices from the map table. Upon the subsequent POST, the default maps are loaded if no maps are present. DeleteAllMaps SaveConfiguration command required DPMTU Controls the MTU, or maximum transmission unit, used by the data port.
IPGateway Controls the current default gateways used by any Ethernet port on the iPBridge. If IPDHCP is enabled, the get command reports the current IP gateway assigned by the network DHCP server. Default: 0.0.0.0 set IPGateway [dp1 | all] [xxx.xxx.xxx.xxx] SaveConfiguration Restart command required get IPGateway [dp1 | all] IPSubnetMask Controls the current subnet masks used by any Ethernet port on the iPBridge.
iSCSIWANIPAddress Sets or displays the IP address reported to an iSCSI initiator located outside the iPBridge LAN. If this iPBridge is behind a NAT router, the address must be set to the external IP address of the router. Setting the address to 0.0.0.0 causes the iPBridge to be inaccessible from outside the LAN. Default: 0.0.0.0 set iSCSIWANIPAddress [dp1] | all] [xxx.xxx.xxx.
Route Assigns an iSCSI protocol address to a target destination device. If you try to map a new SCSI BTL to the same iSCSI LUN, the new BTL overwrites the previous map. Using the Delete identifier instead of SCSI removes the map from its map table. In verbose mode, overwriting a map requires secondary confirmation.
SCSITargetLUNs Controls the maximum number of SCSI LUNs per target the iPBridge queries during a SCSI bus scan. Default: 8 set SCSITargetLUNs [sb] [ 8 | 64] get SCSITargetLUNs [sb] SNMPDumpMIB Displays the contents of the ATTO iPBridge private SNMP MIB to the current CLI session. For further assistance with SNMP, consult your network administrator. SNMPDumpMIB SCSITargets Lists the physical devices that are connected and running on the specified SCSI port.
