***************************************************************************** SCOUNIX.TXT ***************************************************************************** INSTALLATION GUIDE FOR THE SDMS SCO UNIX DRIVER V4.06.00 This file describes the features and use of the Symbios SDMS device driver for the SCO OpenServer 5 operating system environments. These instructions assume that you are using a Symbios host adapter and appropriate SCSI devices. You only need to "link" the new Symbios device driver if you have a Symbios host adapter in the system. Go to the Troubleshooting section for further information about installation to an IDE Hard Drive. This file is divided into the following sections: Introduction Features Description Installing Your SCO Unix Driver Procedure 1, New System Installation Installing the SCO UNIX Driver Installing SCSI Device Support Procedure 2, Existing System Installation Installing the SCO UNIX Driver Adding a SCSI Disk Drive Adding a SCSI Tape Drive Adding a SCSI CD-ROM Troubleshooting Please read the note below before proceeding with the installation instructions. Note: 1) The 4.06 driver supports all of the OpenServer 5 releases of SCO UNIX (Releases 5.0.0, 5.0.2, 5.0.4 and 5.0.5). 2) The 4.06 driver diskette contains package slha, which is for all SCO OpenServer 5 releases. 3) Within the text instructions for adding SCSI Disk Drives, Tape Drives, and CD-ROM drives, the system prompts the user to check whether the driver is the default value or enter the exact driver name. The package name and the driver name are slha. ******************************* Introduction ******************************** SCO UNIX is the first Unix operating system licensed for IBM-compatible microcomputers. The integrated communications, file system, international application support, and documentation create an ideal platform for those requiring a full-featured, UNIX-based operating system. SCO UNIX takes full advantage of the capabilities of the 80386 and above microprocessors. To connect SCSI devices to one or more host adapters, you must place the proper host adapter driver in the SCO UNIX kernel. The Symbios Boot Time Loadable Driver (BTLD) diskette contains one package: slha contains the driver for all SCO OpenServer releases You must link-edit the driver into the SCO UNIX kernel. The kernel must reside on the boot drive: either an internal, non-SCSI hard drive (for example, an IDE drive), or a SCSI hard drive attached to host adapter 0 with SCSI ID 0 and LUN 0. The BTLD permits an easy installation of UNIX with the software provided by SCO. SCO OpenServer provides only one installation diskette, labeled Boot Disk. This diskette, along with the Symbios BTLD driver diskette, and other software media, are used during an SCO OpenServer installation. The following sections provide instruction on configuring the SCO UNIX kernel with the Symbios driver, installing SCO UNIX onto a hard drive, and adding SCSI peripheral devices. These instructions assume you are familiar with UNIX system administration. * * * * * * * * * * * * Features * * * * * * * * * * * o Provides easy UNIX installation on a hard disk with the Symbios Boot Time Loadable Driver (BTLD) diskette o Multiple processor support (with SCO Symmetrical Multiprocessing Support package installed) o Supports synchronous negotiation (including Fast, Ultra, and Ultra2 SCSI) o Supports Wide SCSI (single-ended and differential) o Supports disconnect/reselect o Supports scatter/gather o Allows multiple and non-contiguous LUN support o Allows tagged command queuing o Provides dynamic interrupt mapping o Supports target initiated negotiation o Allows shared interrupts o Supports Multiple LUNs o Allows automatic drive spin up o Supports RAID up to 1024 byte block sizes o Supports NVRAM and NVS configuration data areas New Feature: o Supports termination control via NVRAM and NVS settings * * * * * * * * * * * * Description * * * * * * * * * * UNIX installation on a SCSI system requires creation of a SCO UNIX kernel that contains the SCSI driver to support SCSI devices. There are two possible installation procedures: 1. Installing UNIX and the proper Symbios driver for the first time on a boot drive. 2. Loading or updating the proper Symbios driver on a boot drive. * * * Procedure 1: New System Installation * * * If you plan to perform a new SCO UNIX installation that includes the proper Symbios driver, then follow this procedure. The Boot Time Loadable Driver (BTLD) provides a user-friendly method for installing SCO UNIX onto a hard disk drive. * * * Procedure 2: Existing System Installation * * * If you plan to attach SCSI devices to a Symbios host adapter while using a non-SCSI hard drive (for example, an IDE drive) as the boot hard drive already containing a SCO UNIX system, follow Procedure 2 to install the the Symbios driver on the non-SCSI boot drive. Some of the SCSI devices supported include tape drives, CD-ROM drives, and SCSI hard disk drives used as secondary storage. This procedure is also followed to replace a previously installed Symbios driver on a SCSI or non-SCSI boot drive. Each of these procedures is described in detail below. Symbios recommends that you complete the entire installation in one session. You should have sufficient time (possibly over an hour) available to complete this without interruption. ************************ Installing the SCO UNIX Driver ********************* * * * * * * Procedure 1: New System Installation * * * * * * * This procedure installs SCO UNIX onto a hard disk drive. This installation is necessary to build a new UNIX kernel that includes your Symbios driver. During installation, you are given the option of retaining current partitions on the root hard disk. For instance, you could have a DOS partition or a user UNIX partition already established on the drive. For more details on UNIX installation, refer to the SCO OpenServer Handbook. 1. Link the Symbios BTLD into the UNIX kernel during installation. a. Insert the SCO UNIX installation diskette and reboot the system. This diskette is labeled Boot Disk. b. At the "boot:" prompt (prompt appears without the double qoutes), type: link Press Enter. c. At the next prompt type: slha for all SCO OpenServer Releases. Do not remove the diskette. Press Enter. d. When prompted during the installation, insert either the installation diskette or the Symbios BTLD diskette, and press Enter. If the system prompts you to enter a routine: "Please enter which routine (0-40) to replace '?' to list), 'a' to add "slhainit" at the end [default], 'n' to do nothing, or 'q' to quit" Enter the indicated routine number that appears above this message. The system may prompt with another inquiry: "Please enter which routine (0-2) to replace '?' to list), 'a' to add "slhapoll" at the end [default], 'n' to do nothing, or 'q' to quit" Enter the indicated routine number that appears above this message. e. Continue the installation according to the SCO UNIX documentation. f. The SCO OpenServer system automatically creates a UNIX kernel file called unix.safe during installation. To access this UNIX kernel, type after the "boot:" prompt: unix.safe 2. Install SCSI device support. a. Continue from Procedure 2, step 3. ************************ Installing the SCO UNIX Driver ********************* * * * * * * Procedure 2: Existing System Installation * * * * * This procedure assumes SCO UNIX is already installed on a hard disk drive. This installation is necessary to build a new UNIX kernel which includes the proper Symbios host adapter driver. The basic steps for accomplishing this are outlined below. For more details on UNIX installation, refer to the SCO UNIX System Administrator's Reference manual. 1. The SCO OpenServer system automatically creates a UNIX kernel file called unix.safe during installation. To access this UNIX kernel, type after the "boot:" prompt: unix.safe 2. Install your Symbios driver. a. Insert the Symbios BTLD diskette in the drive and type: installpkg Press Enter to continue. b. A prompt appears to insert the requested diskette. Since the Symbios diskette is already inserted, press the Enter key to continue. c. A prompt now asks for the name of the package. Type: slha for all SCO OpenServer releases. Press Enter to continue. d. If a driver is already present from a previous installation, a prompt inquires about replacing it. Reply y for yes. e. Once the install package (installpkg) has completed, relink the kernel by typing /etc/conf/cf.d/link_unix at the command prompt. f. The system executes the command and then prompts for a response to: 1. Do you want this kernel to boot by default (y/n)? Type: y Press Enter Then the system backs up the old kernel. 2. Do you want the kernel environment rebuilt (y/n)? Type: y Press Enter. g. To activate the new kernel, you must reboot the system. At the command prompt, type: reboot Press Enter. 3.

After the system reboots and the "boot:" prompt appears, press Enter and the new kernel loads. e. Log in as usual. * * * * * * * * * * * Troubleshooting * * * * * * * * * * The following conditions should exist after a successful installation: The directory etc/conf/sdevice.d should contain a file named slha. This file contains the sdevice entries. The directory etc/conf/cf.d contains files sdevice, mdevice, and mscsi. Files sdev.hdr and mdev.hdr describe the values of the possible field entries in the files sdevice and mdevice, respectively. The sdevice file should contain a slha entry for each Symbios host adapter configured in the system. The second field in the sdevice file should read 'Y'. A slha entry should appear in the mdevice file. A slha entry for each configured SCSI device should appear in the mscsi file. Directory /etc/conf/pack.d/slha should exist and contain the files Driver.o and space.c. The following are some potential problems and their suggested solutions: * * * Problem * * * Loading the SCO UNIX kernel to an IDE Hard Drive * * * Solution * * * You only need to "link" if you have a SCSI device attached to a Symbios host adapter. Follow the instructions in the SCO UNIX Installation documentation. Once the installation has completed, then go to Step 2 in Procedure 2 and use the installpkg to install your Symbios driver. * * * Problem * * * A SCSI device is not found. * * * Solution * * * a. Reboot and press Cntl C when prompted to view the Configuration Utility displays. b. Verify the device is on the correct host adapter and ID. c. If the device is not shown, then it is probaby turned off or a cabling problem exists. * * * Problem * * * UNIX System behaves unreliably after a configuration change. * * * Solution * * * Whenever the hardware or software configuration is altered, you must rebuild the kernel. Use the directory /etc/conf/cf.d and type: ./link_unix to rebuild the kernel. * * * Problem * * * An error message occurs during the rebuild of the kernel. * * * Solution * * * a. Reinstall the proper Symbios driver using the installpkg utility. Remember to relink the kernel. b. Reboot the system. * * * Problem * * * The root disk is not found or the partitioning of the disk fails. * * * Solution * * * a. If your boot drive is a SCSI disk, use the SCSI BIOS Configuration Utility to check that the disk is assigned SCSI ID 0 (zero) and is configured to host adapter 0 (zero), LUN 0 (zero). * * * Problem * * * a. A SCSI tape drive is not seen during installation. * * * Solution * * * Use the SCSI BIOS Configuration Utility to check that the tape drive is assigned SCSI ID 2, and that it is configured to host adapter 0 (zero), LUN 0 (zero). Also, verify that the ID of the tape drive does not conflict with any other SCSI device ID. * * * Problem * * * a. A SCSI CD-ROM drive is not seen during installation. * * * Solution * * * Use the SCSI BIOS Configuration Utility to check that the CD-ROM drive SCSI ID is set to 5, and that it is configured to host adapter 0 (zero), LUN 0 (zero). Also, verify that the ID of the CD-ROM drive does not conflict with any other SCSI device ID.
