The KZPEA-DB Ultra 160 SCSI Storage Adapter is a very high performance PCI option module that connects devices attached to its two 16-bit Ultra3 160MB/s LVD/SE SCSI ports to a PCI based host AlphaServer system. The module supports both 32 and 64 bit PCI slots.

Note: The KZPEA supports SCSI bus speeds up to Ultra3 160MB/sec when using LVD signaling

(requiring multi-mode or LVD only terminators on the bus). The fastest the adapter can run in SE mode is UltraSCSI speeds.

Hardware/Firmware Notes

On any XP1000 system the KZPEA-DB module can only be installed in a 64-bit PCI slot.

A video adapter card is recommended to run the on-board configuration utility. On systems such as the HP DS10L, this is not possible since there is only 1 available PCI slot, which precludes the use of a KZPEA board and a video board. On these systems and any others where the choice may be limited to using the serial mode of console operation the following steps are suggested:

At the SRM console prompt, ensure that the console mode of operation is set to “serial.” Go into the KZPEA configuration utility by typing “run bios pkx0”, where x is the assigned letter of the board’s channel A. Once the utility is started and the user has typed control A in response to the board’s inquiry as to whether any of the factory settings need to be changed – at this point the terminal’s setup mode must be invoked to enable the cursor as the KZPEA configuration utility disables the cursor when it starts running. When the cursor is enabled, exit out of the terminal’s setup mode to return to the KZPEA utility and proceed from there.

If your terminal does not present either a flashing cursor or a highlight to indicate where the cursor is, you will not be able to use the serial emulation mode to configure the KZPEA module. Therefore, you must have a video board installed in your system or you must configure the KZPEA in another system and then install it in your system.

Note: KZPEA modules have a restriction with certain graphics modules:

Restricted Graphics

3X-DEPVZ-AA SN-PBXGB-AA

3X-DEPVD-AA SN-PBXGD-AD

SN-PBXGD-AE

SN-PBXGK-BB

SN-PBXGF-AB

3X-PBXGG-AA

Refer to the KZPEA User Guide regarding the board’s SCSI configuration options and their settings.

: Non-Restricted Graphics:

PCI buses containing any restricted graphics modules are limited to one KZPEA adapter on that PCI bus.

On systems with an SN-PBXGD-AD (PowerStorm 300) Video Adapter installed, the printed circuit board (which has part

number 54-25563-01) must be at a minimum revision of C06 in order for the KZPEA to be installed on the same PCI bus.

On systems with an SN-PBXGD-AE (PowerStorm 350) Video Adapter installed, the printed circuit board (which is part

number 54-25561-01) must be at a minimum revision of B05 in order for the KZPEA to be installed on the same PCI bus. There is an alternate printed circuit board used for this video adapter (which is part number 54-25561-02) and it must be at a minimum revision of A03 in order for the KZPEA to be installed on the same PCI bus.

These two graphics adapters are in the restricted column if you are using a version of the SRM console that is earlier than

6.0.

SRM Console Notes

Installations that use version 6.0 or earlier of the SRM console must use the “set pk*0_host_id” feature under SRM as well as setting the host SCSI ID under the “run bios pk*0” feature of the system. These actions are required to change the SCSI ID of a port on the KZPEA board.

Version 6.1 and later of the SRM console will only support using the “run bios pk *0” method of setting the host SCSI ID on the KZPEA board. If you attempt to use the “set pk*0_host _id” feature under SRM console version 6.1 the following message will appear:

“Protected from attempted operation”

Software Notes

The minimum acceptable version of Compaq Analyze is 4.0.

The driver for Tru64 UNIX currently does not do domain validation on warm swaps. Domain validation is only performed during boot time and is performed to ensure that the SCSI bus speed negotiated with the device can be executed without data corruption or bus errors. If an error or corruption occurs during domain validation the speed of the SCSI bus will be decreased until no errors are detected.

Disk warm swaps will force a negotiation with the device that may result in an increase or decrease in SCSI bus transfer speed, depending on the device. A problem would occur using the KZPEA controller if you were using a SCSI-2 storage shelf with SCSI-2 devices and then warm swapped a SCSI-2 device with an ULTRA-160 device. Both the adapter and device would negotiate for the ULTRA-160 speed on a SCSI-2 storage shelf. The subsequent transfers could result in data corruption.

Caution must be used when performing warm swaps to ensure that the hardware (adapter, storage shelf, cables, and device) supports the negotiated SCSI bus transfer speed.

Installation in a Tru64 UNIX TruCluster Server Environment

Information on a cluster installation, including existing clusters, can be found in the TruCluster Server documentation set at: http://h30097.www3.hp.com/docs/pub_page/cluster_list.html

Shared Bus Support

Installation in a Shared SCSI Bus Configuration

The KZPEA is supported in a 2 node shared SCSI bus configuration. This configuration requires the SCSI ID of each channel used in a shared bus on one of the KZPEA adapters to be changed from the default ID 7 to ID 6. There are three possible shared bus configurations (A, B and C).

Note: Configuration A is OBSOLETE and not recommended for new installations. Configurations B and

C are recommended for new installations and upgrades to existing environments.

Note: Configuring dual initiators from the same host on the same SCSI bus is not a supported

configuration.

Configuration A (Obsolete)

Configuration A, (Figure 1), which is an obsolete configuration, requires the use of Y-cables at each node with one adapter being in the middle of the bus. The on-board termination of both adapters in both nodes must be disabled for each channel used in a shared bus configuration. Termination is disabled by removing jumper J5 for SCSI Channel 1/A and jumper J3 for SCSI Channel 2/B, and also setting the Host Adapter SCSI Termination to “Low OFF/High OFF” for Channel 1/A and “Disabled” for Channel 2/B with the SCSI Configuration Utility.

Refer to the KZPEA User Guide regarding operation of the adapter’s onboard SCSI Configuration Utility.

Note: For shared bus configuration only, please disregard the “SCSI Termination” paragraph under

section 2.1.2 of the KZPEA User Guide which states that the adapter can only be located at the end

of the bus, requiring jumpers J3 and J5 to be installed.

Termination will be supplied by the storage enclosure at one end of the bus and by an external terminator at the other end of the bus.

Note: When configuring the KZPEA in a shared SCSI bus configuration which will contain a boot, cluster,

quorum, or dump disk, you must connect the shared cable to Channel A of the KZPEA adapters on both

nodes if using an SRM Console Revision less than V6.6. Console Revisions of V6.6 and greater do not

have this restriction.

Note: Included in the 3X-BN55A-01 Y-cable kit is an HD68 SCSI black connector plug (P/N: 12-10015-

01) that MUST be installed in the internal SCSI connector of the KZPEA for proper shared bus

operation. If only one of the two channels are to be used in a shared bus configuration make sure

that the connector plug is attached to the correct internal SCSI connector associated with that bus

for each KZPEA adapter.

SCSI Cabling Considerations for Shared Bus Support with Configuration A

The maximum LVD bus length for KZPEA shared SCSI bus support is 12 meters (39 feet). This includes the combined length of the two y-cables and the two SCSI cables as well as KZPEA and shelf internal bus lengths. The y-cables are 0.7 meters each. The following cables are supported in the shared bus configuration:

2-5-2 P/N 3X-BC56J-02 341174-B21 313374-001 6 foot VHDCI-to-VHDCI 3X-BC56J-03 341175-B21 313374-002 12 foot VHDCI-to-VHDCI 3X-BC56J-04 164604-B21 313374-004 24 foot VHDCI-to-VHDCI

The maximum allowable SCSI bus length for this configuration is achieved by using a 6 foot 313374-001 cable and a 24 foot 313374-004 cable.

Figure 1 is an example of a Configuration A KZPEA shared SCSI bus configuration.

Figure 1 Configuration A KZPEA, Shared SCSI Bus

Configuration B

Configuration B (Figure 2) requires the use of a Tri-link at the middle node, use of a terminator cable between the middle and end node with one adapter being in the middle of the bus. The on-board termination of both adapters in both nodes must be disabled for each channel used in a shared bus configuration. Termination is disabled by removing jumper J5 for SCSI Channel 1/A and jumper J3 for SCSI Channel 2/B, and also setting the Host Adapter SCSI Termination to “Low OFF/High OFF” for Channel 1/A and “Disabled” for Channel 2/B with the SCSI Configuration Utility.

Refer to the KZPEA User’s Guide regarding operation of the adapter’s onboard SCSI Configuration Utility.

Note: For shared bus configuration only, please disregard the “SCSI Termination” paragraph under

section 2.1.2 of the KZPEA User Guide which states that the adapter can only be located at the end

of the bus, requiring jumpers J3 and J5 to be installed.

Termination will be supplied by the storage enclosure at one end of the bus and by a terminator cable at the other end of the bus.

Note: When configuring the KZPEA in a shared SCSI bus configuration which will contain a boot, cluster,

quorum, or dump disk, you must connect the shared cable to Channel A of the KZPEA adapters on both

nodes if using an SRM Console Revision less than V6.6. Console Revisions of V6.6 and greater do not

have this restriction.

KZPEA Adapter Configuration for Shared SCSI Bus Installation of Configurations A and B

The following steps describe the procedure to disable on-board termination, and also to change one of the adapter’s SCSI ID to 6.

Refer to the system and KZPEA User’s Guides for proper system shutdown, power off and ESD protections.

1) Disconnect any attached cables and remove the on board termination jumper for the bus being configured as a shared bus: J3 for Channel 2/B and J5 for Channel 1/A. Refer to the KZPEA User’s Guide for location of these termination jumpers.

2) Power-up both AlphaServer systems, and at the console prompts perform the following:

a) Type "show config" to display the system configuration information. b) Determine the name of the KZPEA adapter: e.g. pkc0, pkd0, etc. c) Type "init" to reinitialize the system prior to using the “run bios” command. d) Type "run bios pkx0" where x is the assigned letter of the board's channel A. e) Press CTRL-A when prompted to run the KZPEA on-board configuration utility.

3) Perform the following steps in the configuration utility on both AlphaServer systems:

a) Select the channel (1/A or 2/B) that will be configured in a shared bus environment. b) Select "Configure/View Host Adapter Settings" menu. c) Use the arrow key to move the cursor to Host Adapter SCSI Termination, and then press RETURN

to select your options. d) Set Host Adapter SCSI Termination = “Low OFF/High OFF” if channel 1/A was selected, or

“Disabled” if channel 2/B was selected. [NOTE: B channel has different settings than A channel] e) On one of the shared bus AlphaServer systems, change its KZPEA SCSI ID field to 6 (default is 7)

for the appropriate channel being configured into a shared bus environment. f) Press Esc key to get out and save the changes. g) Press Esc key again to exit the configuration utility. The console will reset all I/O buses.

Configuration C

Configuration C (Figure 3) requires the use of a Multi-initiator shelf (MSA30 MI) as well as standard SCSI signal cables between each host and the shelf. The on-board termination of both adapters in both nodes must be enabled for each channel used in a shared bus configuration. Termination is enabled by installing jumper J5 for SCSI Channel 1/A and jumper J3 for SCSI Channel 2/B. The BIOS settings must be as follows: Host Adapter SCSI Termination to “Low OFF/High OFF” for Channel 1/A and “Disabled” for Channel 2/B with the SCSI Configuration Utility.

Refer to the KZPEA User’s Guide regarding operation of the adapter’s onboard SCSI Configuration Utility.

Termination will be supplied by the storage enclosure at one end of the bus and by the SCSI KZPEA adapter at the other end of the bus.

Note: Configuration C requires a minimum SRM Console Revision of V6.6, Tru64 UNIX v5.1B w/pk4 (5.1B-

2/TCR V5.1B-2)

Shared Tape Support

In addition to supporting shared disks the KZPEA can also be used to share a single tape drive between two systems under Tru64 UNIX. Only specific tape drives are supported in the shared bus environment as listed below:

HP StorageWorks SDLT 320 GB Tape Drive

HP StorageWorks SDLT 600 GB Tape Drive

HP StorageWorks Ultrium 448 Tape Drive

Both the external and internal models of these tape drives are supported. The internal models are supported only when installed in one of the Rack-Mount Tape Drive kits listed below:

HP StorageWorks 1U Rack-Mount Kit A7445B HP StorageWorks 3U Rack-Mount Kit 274338-B22

The internal SDLT 600 is supported in the 3U Rack-Mount Kit, but the external SDLT 600 is not supported in a shared bus environment. Refer to your system support statement for a current list of supported tape drives.

The configuration of one of these tape drives in a shared bus environment is very similar to the configuration used to share disk drives. There are two possible shared tape configurations (A and B).

Note: Configuration A is OBSOLETE and not recommended for new installations. This configuration was only supported for the SDLT 320 GB Tape drive. SDLT 600 and Ultrium 448 drives must use Configuration B.

Tape Configuration A (Obsolete) (SDLT 320 only)

Configuration A (Figure 4), which is an obsolete configuration, requires the use of Y-cables at each node with one adapter being in the middle of the bus. The on-board termination of both adapters in both nodes must be disabled for each channel used in a shared bus configuration. Termination is disabled by removing jumper J5 for SCSI Channel 1/A and jumper J3 for SCSI Channel 2/B, and also setting the Host Adapter SCSI Termination to “Low OFF/High OFF” for Channel 1/A and “Disabled” for Channel 2/B with the SCSI Configuration Utility.

Refer to the KZPEA User Guide regarding operation of the adapter’s onboard SCSI Configuration Utility.

Note: For shared bus configuration only, please disregard the “SCSI Termination” paragraph under

section 2.1.2 of the KZPEA User Guide which states that the adapter can only be located at the end

of the bus, requiring jumpers J3 and J5 to be installed.

Termination will be supplied at the tape drive on one end of the bus and by an external terminator at the other end of the bus. Please refer to the documentation for your tape drive to determine how to terminate the SCSI bus at the tape drive.

operation. If only one of the two channels are to be used in a shared bus configuration make sure

that the connector plug is attached to the correct internal SCSI connector associated with that bus

for each KZPEA adapter.

SCSI Cabling Considerations for Shared Bus Support with Configuration A

The maximum LVD bus length for KZPEA shared SCSI bus support is 12 meters (39 feet). This includes the combined length of the two y-cables and the two SCSI cables as well as KZPEA and tape internal bus lengths. The y-cables are 0.7 meters each.

Signal cables between the mid-node and the tape drive: 6-3 P/N 341176-B21 313375-001 6 foot 68-pin HD to 68-pin VHDCI 341177-B21 313375-002 12 foot 68-pin HD to 68-pin VHDCI

Figure 4 Shared Tape Configuration A

Configuration B (Any supported tape drive)

Configuration B (Figure 5) requires the use of a Tri-link at the middle node, use of a terminator cable between the middle and end node with one adapter being in the middle of the bus. The on-board termination of both adapters in both nodes must be disabled for each channel used in a shared bus configuration. Termination is disabled by removing jumper J5 for SCSI Channel 1/A and jumper J3 for SCSI Channel 2/B, and also setting the Host Adapter SCSI Termination to “Low OFF/High OFF” for Channel 1/A and “Disabled” for Channel 2/B with the SCSI Configuration Utility.

Refer to the KZPEA User’s Guide regarding operation of the adapter’s onboard SCSI Configuration Utility.

Note: For shared bus configuration only, please disregard the “SCSI Termination” paragraph under

section 2.1.2 of the KZPEA User Guide which states that the adapter can only be located at the end

of the bus, requiring jumpers J3 and J5 to be installed.

Termination will be supplied at the tape drive on one end of the bus and by a terminator cable at the other end of the bus. Please refer to the documentation for your tape drive to determine how to terminate the SCSI bus at the tape drive.

Note: In Configuration B only SCSI Channel 2/B on the KZPEA is supported for shared bus use with the SDLT 600 or the Ultrium 448 tape drives. These drives cannot be configured on a shared bus using SCSI Channel 1/A on the KZPEA. The SDLT320 tape drive may be used on either SCSI channel
