SNC 5100 Introduction This chapter describes the SNC 5100. It provides the following information: • Overview • Configuration Support • Hardware Product Description and Features • Supported Platforms • Supported Devices • Operating Specifications Overview The SNC 5100 is a 1U high, half-rack width, AC powered storage networking controller. It is the interface between storage and Open System Host interfaces and provides Fibre Channel to SCSI connectivity.
SNC 5100 Configuration Support The SNC 5100 provides two Fibre Channel interfaces. The FC interfaces are configured with Giga Bit Interface Converter (GBIC) modules. In addition, the SNC 5100 has four Ultra2 SCSI interfaces. The Ultra2 interfaces are Low Voltage Differential (LVD). See Figure 3.
SNC 5100 Hardware Product Description and Features This section describes the capabilities of the product and outlines some of the key features of its interfaces. • An IBM 405GP 200 MHz processor, with integrated instruction and data caches, and internal serial I/O and Ethernet interfaces. • An Intel 80303 100 MHz Processor, with integrated instruction and data caches. • QLogic 23x0 Fibre Channel protocol chip • 32 MB ECC protected SDRAM program memory. • 128 MB ECC protected SDRAM data buffer memory.
SNC 5100 Cables should have a duplex SC connector on the GBIC end and a connector appropriate to the HBA in use on the host end. Fibre Channel interfaces support the following Public and Private Loop modes: • Target • Initiator • Target and Initiator The maximum number of initiators connected via Fibre Channel is 64 per Fibre Channel port.
SNC 5100 LUN for command and control so that the remaining 2047 LUNs are available for SCSI devices. For each Fibre Channel interface, the SNC 5100 occupies one Fibre Channel ID and all SCSI target devices are available as LUNs on the same Fibre Channel ID. • The maximum number of initiators that can be connected via SCSI Channel is 1 per SCSI Channel. • The unit provides four SCSI-3 VHDCI connectors for maximum mechanical reliability.
SNC 5100 The service port is used for local service and diagnostics when you use a terminal session to access the shell interface. The service port is configured at: • 19,200 Baud • 8 data bits • No parity • One stop-bit • Hardware Flow Control or Xon/Xoff or other internally detected error conditions LED Indicators The User panel of the SNC 5100 provides LEDs that indicate the status and activity of the SNC 5100 and its interfaces.
SNC 5100 SCSI 1-4 For each SCSI channel, the LED will be OFF when no devices have been detected on the port. It will be ON when a target has been found on the channel. It will flash when there is activity on the channel. The LED will return to the OFF state if the channel is reset. PWR The PWR (Power) LED will be ON when the SNC 5100 has power. It will flash if the on-board power sensors determine that any of the required supply voltages are out of range.
SNC 5100 Supported Devices The architecture and implementation of the SNC 5100 software has full SCSI-2 and SCSI-3 target and initiator support. The SNC 5100 has support for disk, tape, and medium changer devices. The product supports all these devices with the same firmware. Multiple target device type drivers coexist to support different device types. For a current list of supported devices, visit www.adic.com.
SNC 5100 Power Consumption The power consumption of this product depends on the number and type of installed interface options. Maximum power consumption is 45 watts in active mode. The SNC 5100 can provide up to 3.25 watts of termination power per SCSI channel.

For more information, see the ADIC Management Console User Guide Configure the Ethernet Port using information in Step 6 in Table 2: Pre-Installation Checklist. Refer to “Network Setup for the SNC 5100” on page 87.
SNC 5100 Table 3: Installation Checklist Step 15 Actions Verify all target devices are available to the host system. Comments and References Use appropriate host system utilities for disk and tape. See Table 4. If all devices are NOT available, reboot host system(s) and check again. If problem persists, go to “Start MAP” on page 42.
SNC 5100 Post-Installation The ADIC Management Console application allows you to manage multiple SNC 5100s from any location on your network. For installation and operating instructions, see the ADIC Management Console User Guide. Other Installation Issues The SNC 5100 is 8.61" wide x 12.0" deep x 1.61" high. All the connectors, and the air outlets, are at one end of the unit. The air inlet and power switch at the other.
SNC 5100 Transfer Rates: Ultra, Fast, and Asynchronous The SCSI protocol defines two methods of data transfer: synchronous and asynchronous. Asynchronous transfers may run as fast as 5 MB/sec, while synchronous transfers may run as fast as 180 MB/sec (Ultra2/3) at block sizes of 256 k. Performance is system and configuration dependent. The rate of transfer is negotiated between a SCSI initiator, such as the SNC 5100, and each target.
SNC 5100 The SCSI protocol also defines a priority-based arbitration method, based on the target ID of the device attaching to the bus. The SCSI ID priority order is, from highest to lowest, 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8. Table of SCSI Terminology and Limitations The following table (look for updates at http://www.scsita.org/) defines the number of devices supported, based on the negotiated transfer type.
SNC 5100 Table 5: SCSI Trade Association Terminology Notes: 1The listed maximum bus lengths may be exceeded in Point-to-Point and engineered applications. 2 Use of the word "Narrow", preceding SCSI, Ultra SCSI, or Ultra2 SCSI is optional. 3Single-ended 4Not is not defined for speeds beyond Ultra. defined for speeds beyond Ultra2. 5 After Ultra2 all new speeds are wide only. SCSI Bus Termination Each end of a SCSI bus must be terminated correctly.
SNC 5100 Missing terminator at the end of a SCSI bus Check that an external terminator is attached or that the end device has termination enabled. Excessive termination Check that all devices other than the end devices have termination disabled. Multiple devices at the same ID If two or more devices are configured at the same SCSI ID, only one of those devices will be seen by the SNC 5100, and data transfers to that device will be unreliable. Check that only one device is set to each ID.
SNC 5100 Inadequate cables Older cables may not be suitable for running at Ultra speeds. Be sure all cables are rated for Ultra. Mixed cable types If a SCSI bus has both round cables and flat ribbon cables, it may suffer problems when running at Ultra speeds. Use the same cable type consistently for all segments of the SCSI bus. Unshielded cables An unshielded SCSI cable used external to a cabinet may cause reliability problems, due to interference from other electrical devices. Use only shielded cables.
SNC 5100 Step 5. Install optional utility software, if desired. Perform steps 4 and 5 after the SNC 5100 is installed and connected to the host system. Installing the SAN Explorer The SAN Explorer software is only available for hosts running the Windows NT or Windows 2000 operating systems. It allows you to view the LUN mapping through switches to which your SNC 5100 may be attached. It includes the Host Registration Service.
SNC 5100 Some operating systems provide you with software methods that allow you to add or remove SCSI devices dynamically after the host has booted. To ensure reliable operation, reboot the host. If you update SNC 5100 firmware you must reboot in order to use the new firmware. To ensure compatibility between the firmware features or functions and the host, reboot the host.

Connect a service terminal to the SNC 5100. For information about how to do this, see “Connecting to the Service Port” on page 95. Step 2. Press the Enter key on the service terminal. If the prompt is not displayed, go to “Service Port MAP” on page 75. Step 3.
SNC 5100 For information about how to do this, see “Connecting to the Service Port” on page 95. Step 2. Press the Enter key on the service terminal. If the prompt is not displayed, go to “Service Port MAP” on page 75. Check Fibre Channel Port Status Step 1. Enter the fcShow command from the service terminal. For more information, see the "fcShow [level]" command on page 127.
SNC 5100 If all of the attached SCSI devices are not displayed, go to “SCSI Channel MAP” on page 50. Check Channel Zoning Settings Step 1. Enter the fcShowDevs command from the service terminal. For more information, see the "fcShowDevs" command on page 129. Look at the display for each Fibre Channel interface. If all of the SCSI devices are displayed under each Fibre Channel interface, then host access to SCSI devices is not being restricted by Channel Zoning. Step 2.
SNC 5100 Step 2. Press the Enter key on the service terminal. If the prompt is not displayed, go to “Service Port MAP” on page 75. Step 3. If the SNC 5100 is off, then turn it on. Step 4. Verify that the RDY LED is blinking once per second. As the SNC 5100 is booting, several status messages should be displayed on the service terminal. The last status message is “Done executing startup script”. If no status messages are displayed, go to “Service Port MAP” on page 75. Step 5.
SNC 5100 Step 1. Issue the scsiShow command from the service terminal to display a list of attached SCSI devices. For more information, see the "scsiShow" command on page 160. Step 2. For each SCSI channel, make a list of attached devices. Include SCSI device ID, manufacturer, and device status/flags. Step 3. Go to "Compare Listed versus Physical Devices". Compare Listed versus Physical Devices For each SCSI channel, compare the list of attached devices with the physical devices.
SNC 5100 Check SCSI Bus Termination Caution If in this procedure you determine that you need to remove a SCSI cable or terminator, all I/O to the SNC 5100 must be stopped and the SNC 5100 must be turned off. Step 1. Verify the termination for the end device attached to the channel in question. The last physical device on a chain of SCSI devices needs to be terminated. If the end device has internal termination, be sure it is enabled. Otherwise check that an external terminator is attached to the device.
SNC 5100 Check for Multiple SCSI IDs If two or more devices on the same SCSI channel are configured at the same SCSI ID, only one of those devices will be seen by the SNC 5100. Data transfers to that device will be unreliable. Caution If in this procedure you determine that you need to correct any SCSI IDs, all I/O to the SNC 5100 must be stopped and the SNC 5100 must be turned off. Step 1. Enter the scsiShow command from the service terminal. For more information, see the "scsiShow" command on page 160.
SNC 5100 Improper Device Type Step 1. Check to be sure that all the devices attached to a single SCSI bus are of the same type. Only low voltage differential devices must be attached to low voltage differential SCSI channels. When a mix of Ultra2/3 SCSI and Ultra SCSI devices are connected to a single bus, the bus will run at the Ultra SCSI speed. Because the bus will auto-adjust to the slowest speed, it is not recommended that you run both Ultra2/3 SCSI and Ultra SCSI devices on the same bus.
SNC 5100 Examine SCSI Cables Caution If in this procedure you determine that you need to remove a SCSI cable, all I/O to the SNC 5100 must be stopped and the SNC 5100 must be turned off. Step 1. Look for damaged cables. Check for breaks in the cable jacket, exposed or frayed cable shield, exposed or broken wires. Step 2. Replace any damaged cables. Step 3. Look for inadequate cables. Older SCSI cables may not be suitable for running at Ultra2/3 speeds. Be sure all cables are rated for Ultra2/3.
SNC 5100 Examine SCSI Connectors Caution Before removing a SCSI cable, all I/O to the SNC 5100 must be stopped and the SNC 5100 must be turned off. Step 1. Inspect each connector to find out if pins were bent when the connector was attached. Step 2. Replace any cables that have bent pins. Step 3. If you did not have to replace or re-secure a SCSI cable, go to "SCSI Loop Back Test". Step 4. If you replaced or re-secured a SCSI cable, turn on the SNC 5100. Step 5.
SNC 5100 SCSI Loop Back Test Caution Before performing diagnostics, all FC and SCSI cables must be disconnected from the SNC 5100. Before changing any SCSI cables, all I/O to the SNC 5100 must be stopped and the SNC 5100 must be turned off. Do not perform SCSI loop back tests on SCSI channels that are attached to SCSI target devices. If you do this, you will corrupt the data on the device. Step 1.
SNC 5100 Testing SCSI Cables If the cables of the devices attached to a channel have a compatible pinout on both sides, the SNC 5100 can test the cable using the loop back test. Step 1. Stop all I/O to the SNC 5100. Step 2.

SNC 5100 reboot The reboot command requests that the SNC 5100 shut down existing operations and then restart. This is the preferred method of restarting the SNC 5100. There are processes running within the SNC 5100 that may have writes pending to files within the flash file system. Following a reboot command, these processes flush their data to the flash file system, and the flash file system writes all pending data out to the flash memory.
SNC 5100 writes to the flash file system will be lost. This operation is not typically used. The reboot command should be used to gracefully shutdown and restart the SNC 5100.

SNC 5100 An example configuration that requires the Node Name on each Fibre Channel port to be different is where the host has two Host Bus Adapters (HBAs) installed for redundancy. In this configuration, each HBA is connected to a different Fibre Channel port on the SNC 5100. Fail-over software on the host defines one of the HBAs as the primary connection and the other HBA as a spare. If the primary HBA should fail, the fail-over software routes data transfers to the SNC 5100 through the spare HBA.

SNC 5100 Diagnostic Command Reference This section specifies the procedures used when diagnostics are required. Boot Modes The SNC 5100 has two modes of operation: normal mode and diagmode. Two commands are available from the service terminal to reboot the SNC 5100 to the desired mode. The SNC 5100 remains in the existing mode until it has been directed to reboot in the other mode. When the SNC 5100 is booted in diagmode, the command prompt displayed on the service terminal is diagmode >.
SNC 5100 If the command prompt displayed on the service terminal is not diagmode >, enter the diagBoot command. Step 7. Wait for the SNC 5100 to reboot. Step 8. At the diagmode > prompt, proceed with the appropriate diagnostic tests. Restoring Normal Mode Follow this procedure if the SNC 5100 was placed in diagnostic mode and needs to be restored to normal operation. Step 1. Connect the terminal to the Service Port, if it is not already connected. Step 2.
SNC 5100 Event Log Dump The events that have been logged in the SNC 5100’s Event Log can be displayed on the service terminal or viewed from the ADIC Management Console. For more information, see the ADIC Management Console User Guide. This information may be useful because you can see the normal events and any abnormal events that may lead you to the source of an internal or external failure.
SNC 5100 This event is also recorded in the SNC 5100 event log along with the name of a file that was saved to the flash file system. The file contains information about the state of the Fibre Channel interface prior to the reset. Follow these steps to retrieve the file. Step 1. Connect the service terminal to the Service Port.

SNC 5100 Boot Mode Commands diagBoot This command is used only to transition an SNC 5100 from normal operations to the special diagnostic mode. Caution All SCSI and FC cables must be disconnected before entering the diagBoot command. • The diagBoot command first ensures that the /nvfs:mt directory exists. • It copies the existing bootline to a file in the /nvfs:mt directory on the SNC 5100.
SNC 5100 The Ethernet loop back plug, Fibre Channel loop back plug, and SCSI cable provided in the Service Tool Kit are required for the corresponding loop back test. Caution You must disconnect the FC and SCSI cables from the SNC 5100. If you do not, the data on the attached tape devices will become corrupted. elTest elTest is the Ethernet loop back test. The SNC 5100 must be in diagnostic mode to use this command and a loop back plug must be installed on the Ethernet port.
SNC 5100 The fcSlotTest command performs a confidence test on a Fibre Channel slot. Substitute for x the Fibre Channel slot number you want to test. This command can be used to test the slot or the cable. The following example code shows the display for a test Fibre Channel slot 1.
SNC 5100 The example below shows the display for a test on SCSI channels 1 and 2. diagmode > scsiChannelTest (3,4) SCSI-3 -> SCSI-4 [##########] 10 SCSI-4 -> SCSI-3 [##########] 10 value = 0 = 0x0 diagmode > scsiChannelTest (1,2) SCSI-1 -> SCSI-2 [##########] 10 SCSI-2 -> SCSI-1 [##########] 10 value = 0 = 0x0 iterations PASSED iterations PASSED iterations PASSED iterations PASSED The following output is an example of a SCSI port test that was not successful.

SNC 5100 POST Error Codes The Power-On-Self-Test (POST) is responsible for testing the integrity of the processor’s SDRAM. After testing SDRAM POST will attempt to transfer control to either the default bootrom image or an alternate image. POST can also download binary images over the service port and write them to flash memory. This enables POST to perform a minimal amount of emergency recovery from FLASH errors.
SNC 5100 Initial POST Figure 11 Initial POST IpostMain starts by initializing the service-port and the system PLD(s). The ERR LED will extinguish and the RDY LED will turn on. POST will display the following message on the service port: == POST Version nnn == Simple Access Test Figure 12 Simple Access The simple access test verifies that the processor can perform basic writes and reads to the SDRAM. This test is identified by the flash of the FC1 LED.
SNC 5100 Bitwalk Test Figure 13 Bitwalk Test This test first walks a one-bit then a zero-bit through the base of each bank of SDRAM. This test is identified by the flash of the FC2 LED. Memory Size Figure 14 Memory Size This test verifies that the apparent size of SDRAM meets the minimum and maximum sizes specified for the product. This test is identified by the flash of the SCSI1 LED.
SNC 5100 This test writes and reads a series of diagnostic patterns to each memory location in SDRAM. This test is identified by the repeated flash of the SCSI2 LED. This test can take several seconds to complete. Address Test Figure 16 Address Test This test writes and reads address tags to memory to test for bad SDRAM address lines. This test is identified by the flash of the SCSI3 LED. POST then relocates itself to SDRAM and moves it’s stack from processor internal RAM to SDRAM.
SNC 5100 POST will examine the FLASH memory primary bootrom locations to determine whether or not it contains a viable bootrom. If the bootrom appears valid then POST will transfer control to it. If the bootrom image is considered invalid then POST will repeat the bootrom checks at the location of the secondary bootrom. This step is indicated by the flash of the SCSI4 LED.
SNC 5100 Figure 19 NMI 1 The button may be depressed any time during the memory tests.
SNC 5100 R - [R]eceive new boot image from serial port This will start the ZMODEM transfer engine that transfers a single binary bootrom image file to POST using the service port. It should not be used to receive other kinds of binary image files. If the transfer is successful then POST will program the bootrom image into the FLASH memory device. While waiting for the file, POST will display: **B000000023be50 At this point the operator may transfer the bootrom “.
