With respect to disk I/ O, nmon reports back the following data: disk I/ O rates, data transfers, read/ write ratios, and disk adapter statistics. 关于磁盘I/O,nmon可以报告以下数据:磁盘I/O速度、数据传输、读/写比例以及磁盘适配器统计信息。
Plug your root file system disk into the first slot of its adapter. 将根文件系统磁盘插入到适配器的第一个插槽中。
For example, if your root file system's physical disk is attached to a SAS adapter, then your init file may have a field like the following 例如,如果根文件系统的物理磁盘与SAS适配器连接在一起,则init文件可以有如下所示的字段
Configure the host adapter driver to be loaded through an initial RAM disk, which applies the configuration data for redundant disks when loading the adapter module at boot time. 配置主机适配器驱动程序,通过初始RAM磁盘进行加载,初始RAM磁盘将在引导过程中加载适配器模块时对冗余磁盘应用配置数据。
Then, IBM introduced virtual I/ O ( VIO) technology, which allows the same LPARs to use the same storage and network resources, thereby breaking the barrier of disk and adapter isolation. 在此之后,IBM引入了虚拟I/O(VIO)技术,让LPAR可以使用相同的存储和网络资源,由此打破了磁盘和适配器隔离的壁垒。
This cannot be done if the disk is mounted on the Fibre Channel subsystem attached to an adapter that uses this driver. 如果磁盘被挂载在一个连接到使用该驱动程序的适配器的FibreChannel子系统上,那就无法执行这种操作。
D= Disk Gives you more information about your disks, disk type sizes, free, volume groups, adapter, and so forth. D=磁盘(Disk)提供关于磁盘、磁盘类型大小、可用空间、卷组、适配器等更详细的信息。
Edit file init or linuxrc to let your root file system disk adapter appear earlier than all other storage adapters in the same category. 编辑init或linuxrc文件,以使根文件系统磁盘适配器出现在同一个类别中的所有其他存储适配器的前面。
If your server doesn't support disabling the local disk adapter directly, you can simply pull out your local hard disk physically. 如果您的服务器不支持直接禁用本地磁盘适配器,您可以卸下本地磁盘。
A= Disk adapters Gives you details of the disk adapter& like their full type. a=磁盘适配器(Diskadapters)提供磁盘适配器的详细信息,比如它们的完整类型。
Each virtual machine has private virtualized hardware such as a network card, disk, graphics adapter, etc. 每个虚拟机都有各自的虚拟硬件,比如网卡、磁盘和图形适配器等。
Each physical link includes a host adapter in the primary disk subsystem and a host adapter in the secondary disk subsystem. 每条物理链路包括一个位于主磁盘子系统中的主机适配器,以及一个位于辅助磁盘子系统中的主机适配器。
Such an architecture would include a single hard disk, a single Fibre Channel adapter, or a single power source for any piece of equipment. 这样的一种架构通常只包含单个硬盘、单个光纤通道适配器或单个电源供所有设备共用。
The current VIOS and LPAR FC adapter, DS8300 disk, virtual adapter and virtual disk configuration is also captured and used in the planning for the new disk assignments. 当前的VIOS和LPARFC适配器、DS8300磁盘、虚拟适配器和虚拟磁盘配置均被捕获并用在计划中以便进行新磁盘的分配。
Application of USB Disk Adapter in the Ferment Jar Automatic Control System 优盘适配器在发酵罐自控系统中的应用
Release: This command is issued by the owning host bus adapter when a disk resource is taken offline; it frees a SCSI device for another host bus adapter to reserve. release(释放):当磁盘资源下线的时候,这个命令由拥有该磁盘的总线适配器发送。这个命令释放该SCSI设备供其他总线适配器占用。
In this paper, it is described how to integrate rewritable optical disk drives with SCSI interface into environments using IBM PC compatible hardware and the MS-DOS operating system, and some guidelines of designs for SCCI host adapter hardware and its ROM BIOS and device driver are given. 本文讨论了把具有SCSI接口的可重写数据光盘机集成入DOS环境下的PC/AT兼容机中所要进行的工作;给出了SCSI适配器、ROMBIOS及设备驱动程序的设计原则和方法。
