一、获取硬件信息及文档指导：
Adaptec AIC-7899 B SCSI ID #3: HP C5683A

SCO中如何安装配置SCSI磁带驱动器?
如果SCSI主适配器没有安装，你需要先安装它，再继续安装SCSI磁带驱动器。
SCSI磁带驱动器有1/4-inch,8mm和DAT 3种格式,安装步骤如下：
第一步 以root登录，并确认系统在维护模式。
第二步 通过三种方式进入硬件/核心管理。
1 桌面：System Adminisfration→
Hardware/Kernel Manager
2 通过命令行，启动系统管理菜单并选择
“Harduare/Kernel Manager”：
scaodmin→Hardware /Kernel Manage
3 直接用命令行： mkdev tape
第三步 选择第一项“Configure SCSI tape drive”
第四步 选择第一项“Install a SCSI Tape Drive”
第五步 键入SCSI主适配器的字首，选择“h”可列出所
支持的适配器。
第六步 键入主适配器号
第七步 如果中断和I/O地址正确，则对
“change these parameters?”提示符回答
“n”，如果它们不正确键入“Y”来修正它们。
第八步 键入设备所连接的SCSI总线。
第九步 键入目标ID
第十步 键入驱动器的逻辑单位号
第十一步 当出现提示后，更新SCSI配置
第十二步 键入供应商标识串或用默认值
第十三步 键入SCSI版本号，或用默认值
第十四步 键入响应数据格式Response Data Format。
第十五步 选择磁带机驱动器类型
第十六步 键入新引导串，或键入“q”采用默认值
第十七步 查看配置检查其是否正确。重新连接核心并重新引导所用的磁带驱动器。你将被提醒建立一个新的引导应急盘
二、实际操作：

You must create a new kernel to effect the driver change you specified.
Do you wish to create a new kernel now? (y/n)y
The UNIX Operating System will now be rebuilt.
This will take a few minutes. Please wait.
Root for this system build is /
The UNIX Kernel hasbeen rebuilt.
Do you want this kernel to boot by default? (y/n)y
Backing up unix to unix to unix.old
Installing new unix on the boot file system
The kernel environment includes device node files and /etc/inittab.
The new kernel may require changes to /etc/inittab or device nodes.
Do you want the kernel environment rebuilt?(y/n)y
The kernel has been successfully linked and installed.
To activate it, reboot your system.
Setting up new kernel environment
You have successfully re-linked a new kernel.
In order for the changes to be reflected on your emergency boot floppy set,
it is recommended that you run the command '/etc/mkdev fd' and re-create
the emergency boot floppy set with the newly linked kernel.
#init 6
三、测试：
# uname -a
SCO_SV scosysv 3.2 5.0.6 i386
# touch legend.txt
# tar cvf /dev/rct0 legend.txt
a legend.txt 2 tape blocks
# tar tvf /dev/rct0 legend.txt
tar : blocksize = 5
rw-r--r-- 0/3 1024 Jul 09 10:36 2002 legend.txt
