SCSI devices are protected by a diode or similar seminconductor to prevent back flow of the terminator power when more than one device supplies this power. Configure the drive to provide TERMPWR by installing the jumper on J7. Active Termination (16-bit Drives, except SCA & Differential Models) -------------------------------------------------------------------- The drive can be configured to provide or not provide active termination. The drive location on the SCSI bus and the method used to terminate the SCSI bus (active termination or separate terminator) determines how to configure the active termination feature of the drive. NOTE XP32275WD/XP34550WD/XP39100WD drives cannot be configured to provide active termination. Do not install differential 16-bit drives at the end of the bus unless the bus is properly terminated (separate terminator resistor). Otherwise proper operation of the bus cannot be assured. Refer to your system or SCSI controller documentation regarding any specific recommendations regarding drive placement on the SCSI bus and SCSI bus termination. +------------------+------------------------------------------------+ |Drive installation|Active Termination Configuration | |location on SCSI | | |Bus | | +------------------+------------------------------------------------+ |Drive installed |If there is no separate bus terminator used at | |at end of bus |the SCSI bus end that contains the drive, | | |configured the drive to provide active | | |termination. | +------------------+------------------------------------------------+ |Drive installed |If a separate bus terminator IS used at the SCSI| |at end of bus |bus end that contains the drive, configure the | | |drive to NOT provide active termination. | +------------------+------------------------------------------------+ |Drive NOT |Configure the drive NOT to provide active | |installed at end |termination. | |of bus | | +------------------+------------------------------------------------+ Option Connctor +---+--+----+ To configure the drive to provide active termination, |o X o o o 1| install a jumper as shown. |o X o o o o| 12--+--+----+ NOTE XP32275WD/XP34550WD/XP39100WD drives do NOT support active termination.

Then connect the leads from the external selection switch(es) to the referenced pins. Observe the following guidelines while doing so. - ID Bit 0, at Pin 1, is the Least Significant Bit. - SCSI ID Bits 0, 1, 2 and 3 (pins 1, 3, 5 and 7, respectively) are active LOW signals. That is, the bit is a 1 if the corresponding remote switch is closed to ground. - Use pins 2, 4, 6 and 8 as the associated ground returns for ID bits 0, 1, 2, and 3, respectively. The ground returns can be used individually, or the ground returns of all three ID bits can be combined at pin 2, 4, 6 or 8. Spindle Synchronization 16-bit Drives, except SCA ------------------------------------------------- The drive supports synchronized spindle operation. Whether the drive operates as master or slave is determined by the contents of the RPL field in the Rigid Disk Geometry Page (04h) for the drive. The time interval between spindle synchronization checks is set using the Spindle Sync Check Interval bit of the SCSI MODE SELECT command Special Function Control page (25h). The drive always maintains local speed regulation when no reference signal is applied. When the drive operates as a master, it generates a spindle synchronization reference signal (SPINDL_SYNC_REF L). This reference signal is available as an output to other drives at Secondary Option connector pins 10 and 19 (pins 10 and 19 are connected together on the drive). When the drive operates as a slave, it looks for a spindle synchronization reference signal (SPINDL_SYNC_REF L) as an input from the master drive. The slave looks for this spindle synchronization input at either pin 10 or 19 on the Secondary option connector (pins 10 and 19 are connected together in the drive). CAUTION Atlas II series drives can be connected for synchronized spindle operation. Models XP32275, XP34550 and XP39100 drives must not be used for synchronized spindle operation in conjunction with drives from different model series or unpredictable results might occur. For example, XP32275W, XP34550W and XP39100W drives can be connected for spindle synchronization in the same system, but they must not include a synchronization connection to a DSP3210W or Capella series disk drive. NOTE When connecting multiple drives together for spindle synchronization, be sure to use proper cabling techniques to avoid ground loop problems. Attach the spindle synchronization (SPINDL_SYNC_REF L) connection and associated ground connection at the secondary Option connector, pin 5. Connect the associated ground to pin 6.

Spin Up Power On 16-bit Drives, except SCA ------------------------------------------ +2------------------------------+ |o o o o X o o o o X o o o o o| |o o o o o X o o o o X o o o o o| Secondary Option Connector +1------------------------------+ Atlas II drives have three Spin-Up on Power On modes: - Option 1 Spin up occurs immediately when power is applied - Option 2 Drive spin up occurs after a predetermined delay following power on. The delay is equal to a user-specified multiplier, multiplied by one plus the numerical SCSI ID of the drive. This will give a staggered spin-up in multiple-drive installations. - Option 3 Drive spin up is controlled by the START STOP UNIT command. For Option 1, immediate spin up power on, install the jumper across pins 11 and 12 of the Secondary Option connector. For Option 2, spin up after a delay, install the jumper across pins 11 and 12 and from 21 to 22 of the Secondary Option connector. Set delay parameters in the MODE SELECT command, Quantum (Vendor) Special Function Control Page (25h). For Option 3, spin up controlled by the START STOP UNIT command, remove the jumper (if present) from across pins 11 and 12/21/22 of the Secondary Option connector. Remote Busy and Fault Displays 16-bit drives, except SCA --------------------------------------------------------- Busy and Fault status of the drive can be monitired remotely by connecting remote (external) Busy and remote Fault display LEDs to the Secondary Option connector. Remote Busy LED --------------- Connect the cathode side of the remote Busy LED to pin 17, BSY_OUT L. Connect the anode side of the LED to pin 18, +5VDC OUT. Remote Fault LED ---------------- Connect the cathode side of the remote Fault LED to pin 10, FLT_OUT L. Connect the anode side of the LED to pin 18, +5VDC OUT. Disable Unit Attention ---------------------- UNIT ATTENTION condition reporting can be disabled either by setting the DUA bit of the Unit Attention Condition page (00h) of the MODE SELECT command (15h) to 1 or by installing a jumper between pins 29 and 30 of the Secondary Option connector. Disable SCSI Parity ------------------- SCSI Parity can be disables by installing a jumper between pins 27 and 28 of the Secondary Option connector. Disable Synchronous and Wide Transfer Mode Negotiation ------------------------------------------------------ Synchronous Data Transfer and Wide Transfer negotiation can be initiated by the drive or by the Initiator. Default is by the Initiator. The selection of the initiation of these modes can be controlled by the ISN and IWN bits of the Quantum (Vendor) Special Function Control Page (25h) of the MODE SELECT command (15h), or by a jumper installed between pin 25 and 26 of the Secondary Option connector. Enable Narrow Mode (Force 8) ---------------------------- Wide Data Transfer (WDTR) negotiations can be limited to 8-bit responses either by setting the Force 8 bit of the Quantum (Vendor) Special Function Control Page (25h) of the MODE SELECT command (15h) to 1, or by installing a jumper between pin 23 and 24 of the Secondary Option connector. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM XP32275/34550/39100 PRODUCT MANUAL 81-112797-02 12/96 Notes on installation ===================== Drive mounting -------------- horizontally vertically +-----------------+ +--+ +--+ +------------------+ | | | +-----+ +-----+ | | | | | | | | | | | |+----------------+| +-+-----------------+-+ | | | | | | || || +---------------------+ | | | | | | || || | | | | | | || || | | | | | | || || +---------------------+ | +-----+ +-----+ | || || +-+-----------------+-+ +--+ +--+ || || | | || || | | || || +-----------------+ || || ++----------------++ You can mount the disk drive in any position.

Caching ------- The drive contains a large, segmented buffer in RAM that is used to maximize the throughput for sequential read streams. This cache is organized as a number of separate track line segments. Each track line segment can hold data from one complete track on the media, temporarily assuming the identity of the track for all input/ output functions. The buffer is also used to combine or coalesce I/O data on a track- by-track basis, prior to accessing the disk media. Performance is greatly improved by gathering and combining the data on a track basis rather than on a command basis. With this unique system, multiple commands for a particular track are coalesced in the buffer before accessing the media. As a result, multiple I/O commands, that address a single track are logically combined, avoiding multiple disk accesses on multiple rotations. Since most reads and writes are sequential, buffering data before it is stored on the media yields greatly increased throughput for most applications. Embedded Servo System --------------------- Embedded servo information is written in a spoke configuration on every track, on every disk surface. The spokes (or headers) consist of quadrature analog pattern and digital address data. The digital portion of the spoke data are read and used to locate the desired track, spoke, and head number. The quadrature analog signal portion is detected and used by a servo feedback control loop to precisely position the head on the track center. Data integrity and security --------------------------- Atlas II disk drives use a combination of parity checking, error detection coding (EDC), error correction coding (ECC), and check- pointing to protect stored data from media errors, transfer or addressing errors, or errors introduced during sector reallocation. Media Error Protection ---------------------- To ensure that data is the same as data written, the drive computes and appends an Error Correction Code (ECC) to each sector of data stored. The drive uses a 198-bit Reed Solomon code with a 2:1 inter- leave, which can correct up to 10 bytes in each sector. The drive can also correct up to 2 bytes per interleave (up to 4 per sector) in hardware ("on-the-fly"), with no loss in throughput. Spindle Synchronization ----------------------- The drive supports both mastered and masterless synchronization and allows a rotational offset specified in units somewhat larger than a degree. Spindle Synchronization is controlled by the Rigid Disk Geometry and (Vendor) Special Funtion Control pages of the MODE SELECT command. NOTE The drives must be homogenous. Other drive model series such as Atlas I or Capella cannot perform spindly synchronization with Atlas II series drives (but they can otherwise function together). Spindle synchronization can be used to lock an array of drives into a precise rational patters. When the heads on one drive are at a particula address, the heads on the other drives are also known locations. Some mirrored configurations offset drives by half a revolution (180*) to reduce rotaional latency. Other configurations use smaller offsets to optimize system throughput. Knowing how long it takes to set up an I/O operation and transfer data to a drive, the SCSI controller can send the data to one drive and, while that data is being transferred, set up the I/O transfer for the next drive. When the first transfer is complete, the controller is ready to transfer the next, and so on. Special Functions ----------------- Quantum has incorporated a number of unique options into the drive. The (Vendor) Special Function Control page is used to control these options. The options include: - Spin Delay - specifies if the drive should spin-up at power on or wait for a START STOP UNIT command from the host. - Initiate Synchronous Data Transfer Negotiation - a toggle-type parameter that allows the initiator to move between asynchronous and synchrounous modes of data transfer. - Write Protect - Prevents writing to the disk drive. - Spindle Sync Check Interval - specifies the time, in minutes, of the interval between spindle synchronization status checks. - Stagger Spin Delay - allow a series of drives to be spun up at individually, reducing the load on the system power supply. Banded recording ---------------- In banded recording, the disk is divided into multiple bands or partitions (also called notches or bit-zoned areas). Starting at inner band, each next outer band has a hihger recording frequency. The Atlas II drives have 16 bands. The use of multiple-frequency recording greatly increases the capacity of the drive. Power-Up Self-Test ------------------ The disk drive performs a self-diagnostic test immediately at power up. If the drive fails its self-diagnostic tests, it will report sense information but will not spin up. Both the Fault LED and a Busy LED briefly illuminate during spin-up as a lamp test. If the drive passes its self-tests and the spin-up jumper is installed, it spins up and perform further diagnostics on the HDA. The drive indicates "not ready" until the HDA tests are completed successfully. The drive diagnostics test the following: - RAM and ROM chips - Buffer memory - Gate array chips - Read/write encoding circuits - Basic servo functions After a selection time following power-on, the disk drive is able to respond with appropriate status and sense data to the TEST UNIT READY, INQUIRY, and REQUEST SENSE commands. SCSI Configured Automatically (SCAM) ------------------------------------ SCAM is a process of automatic ID assignment that eliminates the need for user involement in the setting of unique SCSI IDs. The drives support and conform to the SCAM-1 automatic ID assignment protocol contained in the SCSI-3 draft standards for SCAM. The drives are also fully compatible with SCSI devices that do not comply with SCAM requirements. ********************************************************************** G E N E R A L ********************************************************************** QUANTUM ATLAS I/II TIPS ===================================================================== Application Note INSTALLING ATLAS II DRIVES ON A DIGITAL SYSTEM Digital System DEC UNIX/DEC OSF rev 3.2 or later ------------------------------------------------------------------- This application note is to be used only as a guideline for the titled subject. The user assumes all responsibility for understanding the interrelationships of this information with other affected software or system products. Quantum Corporation provides this information as a service only, and assumes no responsibility for any damages which could result from the use of this information. The information in this application note is subject to change without notice and is not to be construed as a commitment by Quantum Corporation. Quantum Corporation assumes no responsibility for any errors that may appear in this document. This application note provides instructions for installing the Atlas II family of disk drive products on a Digital system running DEC UNIX / DEC OSF rev 3.2 or later. Note: Before placing any Atlas II drive on any of the following: KZPSA (Wide Differential PCI Slot Controller) or KZPSA (Wide Differential PCI Slot Controller) Set the Always Save Data Pointers (AlwaysSDP) bit. This bit is located in Mode Page 25h/Byte 2/Bit 7. Normally Byte 2 is set to 00hex. To set the Always SDP bit, this must be changed to 80hex. - Adaptec 1740 Controller, usually found in the DEC PC AXP 150 (Jensen) Set the Delay ESP (DlyESP) bit. This bit is located in Mode Page 25h/Byte 5/Bit 3. Normally, Byte 5 is set to 00hex. To set the DlyESP bit this must be changed to 08hex. DRIVE INSTALLATION PROCEDURE 1. Connect drive on the bus (keeping in mind not to conflict id). For this example, let's assume the Atlas II drive is at id1, system disk is at id0, host is at id7, and the bus is BUS 0. 2. Type "show config" at the console level before the system comes up. The user should see all devices on all buses. If the device is on a Turbo Channel slot (for example, tc1), then the user must type "t tc1 confg" to see the devices on that bus. (Please refer to your Hardware Configuration Guide for any questions related to console commands.) 3. After booting the system, type the following in any shell window: scu sho edt | grep "Direct Access" The "scu" command will show all available drives and CD-ROM on the system with their respective bus and ID number. It is important to note bus type, 8-bit or Wide, and target id of the drive. 4. Then type file /dev/rrz*c This should also give a list of device files that each drive and/or CD-ROM is using; e.g., bus 0 ID 0 is /dev/rrz0c, bus 0 ID 1 is /dev/ rrzlc. Rule of thumb: Devices files are numbered from rz0 - rz7 for all ids numbered on an 8-bit single-ended bus 0; from 8 - 15 for ids on an 8-bit single-ended bus 1, and so on_, e.g., bus 1 id 0 is rz8. If you don't have a device file for the drive, refer to the System Administration guide and the man pages on MAKEDEV to determine options. Typically, sysadmin will have to "cd /dev" then execute "./MAKEDEV rz#" to create the missing device files. For wide drives, the steps are the same except device files are 16 per bus; i.e., rz0 through rz15 for a wide bus 0. 5. Once the device file has been identified (e.g., for bus 0 ID1, it would be /dev/rrz1c), type one of the following drive models: disklabel -rw rzl xp39100 - for 9GB, or disklabel -rw rz1 xp34550 - for 4GB, or disklabel - rw rz1 xp32275 - for 2GB At that point, the drive is ready to be used with the system. Type disklabel -r rz1 (to see the partition label of the drive). To set up the drive in any other way other than the standard disklabel, refer to the System Administrator's Guide and the man pages on disklabel to determine options. ===================================================================== Application Note INSTALLING ATLAS II DRIVES ON A DIGITAL SYSTEM Digital System Windows NT -------------------------------------------------------------------- This application note is to be used only as a guideline for the titled subject.

It is up to the user at that point to make sure that the necessary steps are completed to make the drive useful in Windows NT, i.e., formatting, partitioning, etc. ===================================================================== AHA 154x, 174x and possibly some newer models: There is a timing issue in that old Adaptec host adapters cannot work at the full speed of the Atlas (specifically, hardware read cache hits in the drive are handled too quickly and the host adapter isn't ready for data when the drive starts to send, so bytes get lost.) Fix: Use DSP tools (PUBLIC\TOOLS\DSP) to set the ESPDLY bit in mode page 25h. How: See ESPDLY.TXT. AHA 2940UW: Installing NT4.0 over an AHA-2940UW onto an Atlas with XL912 may not work. We are also getting reports of XL912 not working up to par on other systems. Vcommunications, for example, is requiring XL915 for their System Commander software. In response to this, DSE techs have been informed as to how to identify Atlas module types and firmware revisions, and have been instructed to upgrade anyone with XL912 to XL915. The required upgrade materials (FW, DSPTools, instructions) can be found on our BBS in the XL915 library, on our FTP site at ftp.qntm.com/pub/ Support/Firmware/Atlas, and by email per request. We stand firm that Quantum offers no service or support for customers who opt to upgrade their firmware without first consulting a qualified technician. The technician shall judge the technical ability of the customer before offering DSP Tools, and may work with the product specialist to have the drive sent to Quantum for a FW upgrade. There are two different hardware versions for wide drives, type 22962 and type 60059. They can be distinguished via a different secondary option connector (the one at the back between the two LEDs.) Type 22962 has a 14-pin option connector, 60059 has 12 pins. Use firmware A?W14*.FUP for module type 60059, A?WXL*.FUP for all others. ===================================================================== Installing NT4.0 over an AHA-2940UW onto an Atlas with XL912 may not work. We are also getting reports of XL912 not working up to par on other systems. Vcommunications, for example, is requiring XL915 for their System Commander software. In response to this, DSE techs have been informed as to how to identify Atlas module types and firmware revisions, and have been instructed to upgrade anyone with XL912 to XL915. The required upgrade materials (FW, DSPTools, instructions) can be found on our BBS in the XL915 library, on our FTP site at ftp.qntm.com/pub /Support/Firmware/Atlas, and by email per request. We stand firm that Quantum offers no service or support for customers who opt to upgrade their firmware without first consulting a qualified technician. The technician shall judge the technical ability of the customer before offering DSP Tools, and may work with the product specialist to have the drive sent to Quantum for a FW upgrade.

This issue has also been found on the DECpc AXP 150 system running an Adaptec 1740 adapter. A feature called ESP_Delay was added on Atlas I drives to work around a problem with some Adaptec adapters (1740, 1540). The Atlas I was a little too fast for the Adaptec adapter and we, therefore, added the ESP_Delay via a mode page bit. We found that the ESP_Delay time was incorrectly set as we increased the clock speed on Atlas II. This issue was found on the DECpc AXP 150 system running an Adaptec 1740 adapter. Firmware version XLXQ1 only increases the delay time. We will still be shipping into distribution with ESP_Delay off. If a customer has a problem with the adapter, we will supply the tool to turn on ESP_Delay instead of loading new firmware. Adaptec SCSI PCI Ultra 2940U/UW adapter: Serious disk errors under DOS Xcopy While running DOS Xcopy (especially with the large files - 1 to 2 MB in size), the system reports a serious disk error has occurred while writing to the drive. This issue occurs on the Adaptec 2940 U/UW with Bios version 1.21. Adaptec upgraded the Bios on SCSI PCI Ultra 2940U/UW adapter to version 1.23 Therefore, this issue should be resolved with Adapter 2940U/UW Bios versions 1.23 or higher. ===================================================================== ESPDLY.TXT Setting the ESPDLY bit with DSP tools (for Atlas and Atlas II drives) Start DSP tools.
