-----------------------------------------------------------------------------
DAC960 Driver:
- MSCSI Compliant
- Multi Processor Safe, Multithreaded
- Single driver for Uniprocessor and Multiprocessor Environments.
- Supports upto 4 DAC960 adapters
- Supports Non-Disk Devices on any Channel. SCSI Id's need to be unique
across channels.
- Adapters/Hard Disks can be configured using standard SCO utilities
- Supports EISA, PCI and MCA DAC960 models
- Support for DAC960-PCI New FirmWare Version 3.x
- Supported under SCO Rel 5.00
Utilities:
- dac960sh (Ver 4.00) - Front end DAC960 Shell Administrator Utility
- dac960tk (Ver 4.00) - To perform low level DAC960 specific commands
- rbldsh (Ver 4.00) - Utility to rebuild redundant system drives
- dacmon (Ver 4.00) - Monitor utility to monitor all configured
DAC960 Adapters
Packaging:
- The driver and utilities are packaged in SCO BTLD format
Installation:
Driver can be installed using either of the two methods
- Fresh SCO UNIX installation.
driver can be linked during Boot Time. At the Boot: prompt, type in
ahslink
NOTE: The following messages appear on the screen
Driver <mdac> apparently should be replaced with
the new driver "mdac". Replacing a driver may
result in a kernel which does not work.
Please enter
'r' if you wish to try replacement
'a' if you want to use character major 6 [default]
which character major number (0-100) to use ('?' to list),
or 'q' to quit:
Enter "r" here
Naming convention:
- Driver package name: mdac
- Driver name : mdac
- Adapter Nodes name : /dev/rdaN00, where N is adapter number
- Hard Disk/Tape/Cd-ROM nodes: SCO standard naming.
How to Configure:
- All MSCSI compliant drivers need to follow strict SCO UNIX procedures
to configure Adapters and SCSI devices. The driver would recognise only
those adapters/devices configured using MSCSI support utilities.
Driver would recognize configured adapters and devices only.
- Configuring Hard Disks:
Use 'mkdev hd' to configure Hard Disks.
system drives should be configured as follows.
system drives 0-7 - Adapter X, SCSI ID 0-7, LUN 1
system drives 8-15 - Adapter X, SCSI ID 0-7, LUN 2 (Fw Ver >= 3.x)
system drives 16-23 - Adapter X, SCSI ID 0-7, LUN 3 (Fw Ver >= 3.x)
system drives 24-31 - Adapter X, SCSI ID 0-7, LUN 4 (Fw Ver >= 3.x)
- Configuring Tape:
Use 'mkdev tape' to configure Tape devices.
Configure Tape at SCSI Id 'X' and LUN 0.
Note : Do not configure Tape Device at SCSI ID 0
- Configuring CD-Rom:
Use 'mkdev cdrom' to configure Tape devices.
Configure CD-Rom at SCSI Id 'X' and LUN 0.
Note : Do not configure CD-ROM Device at SCSI ID 0
- Default Configuration:
When a Fresh SCO unix installation is done using the BTLD package,
the following are automatically configured to facilitate SCO
UNIX installation.
Hard Disk - SCSI ID 0 (System Drive 0)
- Host Adapter 0 (first DAC960 Adapter)
- LUN 1
Tape - SCSI ID 2 (SCO Unix mandates this)
- Host Adapter 0 (first DAC960 Adapter)
- LUN 0
Driver Scanning:
- The driver scans for DAC960 adapters in the following order
1). DAC960 PCI adapters with FirmWare version < 3.x
2). DAC960 PCI adapters with FirmWare version >= 3.x
3). DAC960 EISA adapters
4). DAC960 MCA adapters
Note that it is very important to remember this order, while configuring
adapters (hardware, software), in order to ensure consistent mapping
across driver/utils/hardware.
Errors during Installation:
--------------------------
During fresh installation of SCO Unix Rel 5.00 using DAC960 driver BTLD
diskette "mdac", the following error message appears on the screen
Error Message: Extracting BTLD distribution for mdac ...
/etc/uadmin getdev b mdac: (No such device 19)
Status: This doesn't seem to have any effect on installation. The system
would work fine once the installation is complete. This issue is being
invsetigated.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
