3 Configuring the A7173A Adapter This chapter contains the following sections describing configuration of the A7173A adapter: • “Setting the SCSI Parameters” (page 23) • “About SCSI IDs” (page 24) • “About the Maximum Data Transfer Rate” (page 24) • “About Bus Width” (page 25) • “About Auto-Termination” (page 26) • “Configuration Worksheet” (page 27) • “Setting and Confirming SCSI Parameters Offline” (page 28) • “Setting and Confirming SCSI Parameters Online” (page 39) • “Setting SCSI Parameters to Default
NOTE: The bus width parameter cannot be set offline on rp24xx and rp54xx systems. The SCSI parameters for A7173A adapters installed in HP Integrity systems can be confirmed or changed offline using the Extensible Firmware Interface (EFI), see “Using the EFI Utility on HP Integrity Systems” (page 32). The SCSI parameters for an A7173A adapter installed in any supported HP-UX system can be confirmed or changed online using the mptconfig command, see “Using mptconfig for Online Configuration” (page 40).
• • • • • Fast (20 MB/s) Ultra (40 MB/s) Ultra2 (80 MB/s) Ultra160 (160 MB/s) Ultra320 (320 MB/s) The actual data transfer rate between the A7173A adapter and the other SCSI devices on the bus depends on the maximum data transfer rate that is automatically negotiated for each of the devices on the bus.
TIP: HP recommends that you always use the A7173A’s maximum bus width (16 bits), unless you have Narrow (8-bit) devices on the bus and you are experiencing problems with the connection. Setting the Bus Width Offline For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set bus width offline. See “Using the BCH Menus on HP 9000 Systems” (page 28), for details. NOTE: The bus width parameter cannot be set offline on rp24xx and rp54xx systems.
Configuration Worksheet The worksheet in Table 3-1 provides a convenient format for recording installation details for multiple SCSI adapters: Table 3-1 SCSI ID Settings System Name Slot # Hardware Path SCSI ID Channel Ch. A Ch. B Ch. A Ch. B Ch. A Ch. B Ch. A Ch. B Ch. A Ch. B Ch. A Ch. B Ch. A Ch. B Ch. A Ch.
Setting and Confirming SCSI Parameters Offline If the A7173A adapter is installed in a supported HP 9000 system, use the scsi command, accessed from the BCH menus, to set or confirm the SCSI parameters offline. If the A7173A adapter is installed in a supported HP Integrity® system, a menu driven Extensible Firmware Interface (EFI) utility is available to set or confirm the SCSI parameters offline. See “Using the EFI Utility on HP Integrity Systems” (page 32).
3. Compare the installed PDC version with the recommended PDC version to use the A7173A adapter with your system. For recommended PDC (System Firmware) versions, see the HP Ultra320 SCSI Host Bus Adapter Support Matrix, at: http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters If you do not have the correct PDC version on your system, contact your HP support representative for instructions on updating the PDC.

------------------------------------------------------------------------------ CAUTION: Set the initiator ID on a SCSI adapter carefully. Duplicate SCSI IDs on a SCSI bus can result in bus hangs, system hangs, and system panics. The mptconfig command will attempt to verify that no targets are using the specified ID before the change is allowed; however, in the case of multi-initiator (shared bus) configurations, the mptconfig command cannot detect the presence of other initiators on the SCSI bus.
Setting SCSI Parameters to Default Values The default SCSI parameter settings for the A7173A adapter are: • • • SCSI ID = 7 Maximum Data Transfer Rate = MAX (320 MB/s) Bus Width = 16 bits (Wide) • On HP 9000 systems, the SCSI parameters for the A7173A adapter can be set to the default values offline, using the SCSI command accessed from the Boot Console Handler (BCH) menus. Offline Depending on the system, the SCSI command may have a “default” option. If there is a default option, use it.
4 HP A7173A Administration and Management This chapter contains the following sections detailing A7173A adapter Administration and Management tasks: • “Performance Tuning” (page 45) • “Online Replacement of the A7173A Adapter” (page 45) • “Verify or Update A7173A Adapter Firmware On HP 9000 Systems” (page 46) • “Verify or Update A7173A Adapter Firmware on HP Integrity Systems” (page 46) • “Using mptutil to Verify or Update A7173A Adapter Firmware” (page 46) Performance Tuning To get the best performance fr
IMPORTANT: If the replacement A7173A adapter is new, meaning that it has never been installed, the mpt driver will continue to use the SCSI parameter settings that are already configured on the slot. If the A7173A adapter has been previously installed in a different slot or system, the SCSI parameter settings will not migrate to the new slot or system. In either case, it is still strongly recommended that the SCSI parameter settings be confirmed, and changed if necessary.
1. Use the ioscan -fnkd mpt command to determine the device file for each channel of the A7173A adapter.
Example 4-2 Typical mptutil Command Output # mptutil /dev/mpt14 ****************************************************************************** **** **** **** M P T U T I L S u p p o r t T o o l **** **** **** **** for Ultra320 SCSI Controller **** **** **** **** Version 1.02 : Oct 22 2006 **** **** **** **** (c) Copyright 2003 Hewlett-Packard Development Company, L.P.
3. Use the -d option of the mptutil command to update the SCSI firmware on the A71713A adapter. The command syntax is: mptutil -d where is the name of the SCSI firmware image file you want to flash to ROM on the A7173A adapter, and is the device file name for one of the channels on the A7173A adapter. Since both channels on an A7173A adapter share the same ROM, the SCSI firmware image can be flashed to ROM via either channel.
5 Troubleshooting The A7173A adapter is a single field-replaceable unit (FRU) and does not contain any field-serviceable parts. Troubleshooting procedures described in this chapter are limited to verifying that the adapter is operational and that a valid connection is established. This chapter contains the following sections describing how to troubleshoot the A7173A adapter: • • • • • • • • • • • “General Troubleshooting Procedure” (page 51). “Creating Missing Device Files” (page 52).
6. 7. Confirm that the correct disk device firmware version is installed on your hard disks. You can obtain disk firmware updates from the ITRC web site (http://itrc.hp.com). Search for the model number of the disk drive(s) that you want to update. Installation instructions are provided in the firmware download package. Run the Support Tools Manager (STM) diagnostics application (see “Using Support Tools Manager (STM)” (page 61)).
5. If the A7173A adapter firmware is not current, install the latest firmware, see “Using mptutil to Verify or Update A7173A Adapter Firmware” (page 46). a. Use the mptutil command to display information about the controller. b. Examine the “Chip Information” section of the mptutil output to determine if the driver state is “operational.” 6. If the driver state is still not operational, or if the firmware did not require an update, then the card may be faulty.
Table 5-1 Problems Detected By Domain Validation (continued) Problem Possible Cause Excessive cross talk Poor shielding or grounding. Excessive system noise Poor shielding or grounding. When Domain Validation determines that communication with the target device is not possible at the maximum data transfer rate supported by the adapter (Ultra320), it writes a warning message to the /var/adm/syslog.log file.
