sco openserver 下配置磁带机

sco openserver 下配置磁带机 SCO OpenServer 5下磁带机的配置 磁带和软盘一样都是备份数据和程序用的媒介,使用软盘必须有软盘驱动器,同样使用磁 带也必须有磁带机。 现在磁带的容量有多种,最先出现的是45MB、60MB、100MB,接着为125MB(120MB)和155MB(150MB)、200MB、250MB,比较近的又有525MB、1.0GB、1.2GB、2.0GB、2.5GB、4.0GB和5. 0GB的磁带,将来容量会越来越大,它的大容量好处会越来越明显。 磁带的容量不同,磁带的格式也不同,磁带的格式有早期的QIC-24、QIC-40、QIC-80,随 后发展成为QIC-120、QIC-150,现在又发展成为QIC-525、QIC-1000、QIC-2GB、QIC-2GB AL DC、QIC-3040等。 随着科技的发展,磁带机的型号有多种,UNIX系统根据设备分为Cartridge、Mini-Cartr idge、QIC-40或QIC-80和SCSI接口。根据磁带机控制器类型又可分为ARCHIVE、Wangtek、E merald、Mountain、Tecmar、Everex、Tandberg等,而Xenix系统根据每种类型的第一个字母 分别简称为A、W、E、M、T、X型等(注:Everex简称X型)。 随着科技的发展,出现了多种总线,有:ISA、EISA、PCI等,设备级接口也发展几种类型, 有ST506接口、ESDI接口、SCSI接口、IDE接口和EIDE接口等。很多设备如CD-ROM、磁带机等 ,每一个SCSI接口可以接七个设备,每一个设备分配不同的设备ID号(0,6),其中7分配给SCS I控制器,同一个SCSI通道上的设备一定不能有相同的ID号,否则会发生设备冲突,所以在安装 设备前先查看硬件上有无冲突,如发生冲突要先改硬件参数,SCSI共有四种:SCSI-?、S CSI-?、FAST SCSI-?、FAST/WIDE SCSI-?,微机上现在常用的SCSI为SCSI-?和FAST SCS I-?。 现将Wangtek和Tandberg安装介绍如下供大家参考: Tandberg磁带机的安装方法 Tandberg的接口为 SCSI接口,Tandberg磁带机接在SCSI电缆上,系统开机时显示SCSI的各种设备的host adapter、ID号、LUN号,系统已检测到此设备。 键入命令"#mkdev tape",并回车。 屏幕显示: Tape Drive Configuration Program(磁带机配置程序) 1.
