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.

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.

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.
