raid 初始化方法
raid 初始化方法RAID 初始化方法RAID(Redundant Array of Inexpensive Disks)是一种数据存储技术,通过将多个磁盘组合起来,提供更高的数据安全性和性能。
RAID初始化是指在使用RAID技术之前,需要对磁盘进行初始化配置的过程。
下面将介绍几种常见的RAID初始化方法。
1. RAID 0初始化RAID 0是一种无冗余的RAID级别,它将多个磁盘组合起来,将数据分散存储在各个磁盘上,从而提高数据的读写速度。
RAID 0初始化的步骤如下:(1)选择要组成RAID 0的磁盘,确保它们的容量和型号相同。
(2)进入计算机的BIOS设置界面,选择RAID设置选项。
(3)选择创建RAID 0阵列,并选择要组合的磁盘。
(4)完成RAID 0初始化后,可以将其格式化并分配给操作系统使用。
2. RAID 1初始化RAID 1是一种具有镜像冗余的RAID级别,它将数据同时写入两个磁盘,以提供数据的冗余备份。
RAID 1初始化的步骤如下:(1)选择要组成RAID 1的磁盘,确保它们的容量和型号相同。
(2)进入计算机的BIOS设置界面,选择RAID设置选项。
(3)选择创建RAID 1阵列,并选择要组合的磁盘。
(4)完成RAID 1初始化后,可以将其格式化并分配给操作系统使用。
3. RAID 5初始化RAID 5是一种具有分布式冗余的RAID级别,它将数据和校验信息分散存储在多个磁盘上,以提供数据的冗余备份和高性能。
RAID 5初始化的步骤如下:(1)选择要组成RAID 5的磁盘,确保它们的容量和型号相同。
(2)进入计算机的BIOS设置界面,选择RAID设置选项。
(3)选择创建RAID 5阵列,并选择要组合的磁盘。
(4)设置RAID 5的存储容量和校验信息分布方式。
(5)完成RAID 5初始化后,可以将其格式化并分配给操作系统使用。
4. RAID 10初始化RAID 10是一种具有镜像和分布式冗余的RAID级别,它将多个RAID 1阵列组合起来,提供更高的数据安全性和性能。

Handling PrecautionsAllow the drive to reach room temperature before installing it in the computer.Do not open the E S D bag until youÕre ready to install the drive. Handle the drive by its sides. Do not touch the circuit board (electronics). Do not connect/disconnect any drive cables while your computer is turned on.Do not drop, jar, or bump the drive.1PreIn s tallatio nT hank yo u fo r se le c ting a Maxto r hard d rive sto rag e p ro d uc t.Maxto r's g o al is to p ro vid e yo u w ith the m o st up -to -d ate p ro d uc t p o ssib le ,and w e are c o nstantly e nhanc ing o ur so ftw are and d o c um e ntatio n to b e tte r m e e t yo ur ne e d s .Ple ase visit o ur w e b -site at to vie w the late st that Maxto r has to o ffe r!System /OS Requirem ents¥ A full version of your operating system (OS) is required for a new hard drive installation(see kit package for details)Tools for InstallationThe following tools are needed to install your new M axtor hard drive:¥Small Phillips head screw driver ¥Small pair of pliers or tweezers ¥Your computer user manual ¥Operating system softwareBackup Your DataM axtor highly recommends that you make a backup copy of your files before installing the new M axtor hard drive.Please refer to your computer user manual for more information.2D r ive J um p e r S e t u p Configure the Drive J um persIf specific jumper options are needed for your system configuration, refer to the illustrations and definitions provided in this section.SCSI ID J umper SettingsM axtor SCSI drives typically ship from the factory with jumpers set to SCSI ID 6, and termination power jumped.SCSI ID 7 is usually reserved for the SCSI host adapter.3D rive InstallInstalling Drive Inside of Y our Com puter SystemM ake sure your com puter is pow ered dow n before installing the drive.The following illustrations are of typical computer systems and hard drive mounting styles.Your computer may have a different mounting style. Please refer to your computer user manual for more information.B e sure to secure the drive to the device bay with all four screws.The drive should be oriented with its printed circuit board facing down.Installing 5.25-inch Mounting BracketsIf the hard drive will be installed in a 5.25-inch device bay, attach mounting brackets (available separately) to the hard drive as shown in the figure below.Mounting ScrewsMounting ScrewsMounting BracketNote:M axtor LVD SCSI drives do not support on-board termination. M axtor recommends the use of Active LVD terminators and 68-pin twisted pair cabling.S CS I hos t adapter manufacturers us ually s upply proper cabling and termination with the purchase of an LVD S CS I hos t adapter.A ttention:The R ear J umper O ption Connector is an O E M specific con-nector. M ost installations will never use the jumper options on this connector. Always configure the drive using the jumpers at the Front J umper O ption Connector .Other J umper SettingsTP - Termination Pow er (12 Pin O ption Connector)Pins 11-12 T ermination power ensures that there is a sufficient power level along the entire SCSI bus. It is recommended that the final device on the SCSI bus have the Termination Power jumper installed. All devices in between the host and final device typically have no jumper on Termination Power.Note that Termination Power is not the same as on-board termination, which this drive does not support.S S - S tagger S pinPins 13-14 For most configurations this option is not utilized.M ost current SCSI host adapters offer a Start Unit command enable or disable, which supersedes the functionality of the SS jumper setting. W hen the Delay Spin (DS) jumper isenabled on the drive, the Start Unit command from the SCSI host adapter will send Start Unit commands to all devices on the bus at pre-determined intervals. This can help prevent power supply overload when running several devices on the SCSI bus.W P - W rite ProtectionPins 11-12 B y factory default, the drive is shipped with no jumper on these pins, and the drive can be written to unless protected by application software. W ith the pins jumped, the drive can be used as a read-only device. This feature prevents accidental overwrites and is useful for frequently accessed archives and reference files.Force S E Ð Force S ingle Ended O perationPins 17-18 By factory default, the drive is shipped with no jumper on these pins. W ith most system configurations, it is not necessary to use this jumper. LVD drives are multi-mode capable. They will automatically detect the presence of a sin-gle-ended bus and revert to single-ended mode.DS - Delay S pin Disable Delay S pin: No jumper across pins 15-16 (factory default). Disabling Delay Spin allows the drive to spin up when the system is powered up.Enable Delay S pin: J umper across pins 15-16 This setting will prevent the drive from spinning up until it receives a Start Unit command from a SCSI host adapter. M ost SCSI host adapters have the Start Unit command enabled by default in the host adapter BIOS. Enabling Delay Spin is only necessary when you are starting multiple devices at power on.S CS I IDPin numbers 1-8 are typically referred to in pairs as A0 (pins 1and 2), A1 (3,4), A2 (5,6), A3 (7,8). The jumper pairs will allow configuration of SCSI ID's 0 to 15. All SCSI devices must have an individual ID on the SCSI bus (there is no M aster/Slave set-ting). SCSI ID 7 is usually reserved for the SCSI host adapter.Fault LED and B usy O ut J umpersTypical installations do not require the use of the Fault LED and Busy Out jumpers. The Busy Out signal is usually supplied through the PCI bus to the PC motherboard's Busy indicator LED. If connecting the Busy Out jumper for a drive installed in an external case, please refer to the wiring documentation sup-plied by the manufacturer of the case. Connection of the Fault LED is not recommended in internal or external installations.Computer with available 3.5-inch device bayComputer with available 5.25-inch device bayD I e v i r D O t i B D I 1t i B D I 2t i B D t i B D I 0D I F F O F F O F F F O 1D I N O F F O F F F O 2D I F F O N O F F F O 3D I N O N O F F F O 4D I F F O F F O N F O 5D I N O F F O N F O 6D I F F O N O N F O 7D I T SO H I S C S R O F D E V R E S E R 8D I F F O F F O F F O N O 9D I N O F F O F F O N O 01D I F F O N O F F O N O 11D I N O N O F F O N O 21D I F F O F F O N O N O 31D I N O F F O N O N O 41D I F F O N O N O N O 51D I NO NO NO NO Pin 2Pin 1Pin 17Pin 18SCSI ID 3SCSI ID 2SCSI ID 1SCSI ID 0BUSY LED -/+WRT PROTECT STAGGER SPIN DELAY SPINSINGLE ENDEDFAULT LED GROUND GROUND BUSY LED GROUND TERM POWERSCSI ID 3SCSI ID 2SCSI ID 1SCSI ID 0NOT USED+5 VPin 1Pin 2Pin 11Pin 124 Pin PowerConnector12 Pin Option Connector68 Pin SCSIConnectorPin 168-pin Connector68-pin Drive ConnectorDC Power ConnectorUltra LVD/SE CablePower Supply Cable(3-Pin or 4-Pin)Bevel4Cable Hook-up Attach the SCSI and Power CablesIf the M axtor SCSI drive is the only device attached to the SCSI adapter card, attach the drive at the end of the Ultra LV D/SE cable, farthest from the SCSI adapter card. This connector has a beveled edge and will only fit one way. Then attach an external active LVD/SE SCSI terminator.Please refer to the SCSI adapter card user guide for additional recommendations on data cable place-ment and SCSI termination requirements.Attach a power cable to the power connector on the hard drive. This connector is keyed and willonly fit one way. Check all other cable connections before you turn on the computer.Caution:Do not force or rock the connectors into their sockets on the hard drive. Push them in straight until they are seated firmly.5P a r t it io n i n g F o r m a t t i n gMaxtor hard drives can accept nearly all operating systems. Some operating sys-tems have volume size limitations that may require you to partition your drive into multiple volumes. Please refer to your system or SCSI adapter card user guide for information about formatting and partitioning the drive.General Guidelines¥ DOS /W indow s 9X /M E:Use FDISK.EXE to partition and FORM to format the drive.¥ W indow s N T/2000:Boot your system from the installa-tion floppy disks provided with the OS to partition and format the drive.If you do not have the original installa-tion floppies, you can create them using your W indows installation CD.¥ W indow s X P:Boot your system from the W indows XP installation CD to partition and for-mat the drive.

(文档库)解码位置代码
解码位置代码在一个设备显现故障时,您需要明白该设备在系统中的物理位置,以即能够改换它。
errpt或lscfg命令提供了一个位置代码,指定了故障设备所在的位置。
有了位置代码和效劳器手册,或包括您的型号的IBM® Redbooks®,乃至您能够访问IBM Web 信息中心取得更有效的信息,您就能够够识别设备所在的确切位置。
简介碰到设备故障确信是一件麻烦事。
故障设备的类型可能是热插拔硬件,比如风扇冷却装置或热插拔外设组件互连(PCI)卡。
在这两种情形下,都需要明白设备的物理位置,然后才能改换它。
因此,您需要明白设备的位置代码。
故障设备会显示在错误报告中(利用 errpt 命令),该报告还会发布物理位置代码。
另外,利用 lscfg 命令能够取得您设备的物理位置。
在取得该位置后,应该如何定位设备?AIX 内部代码和物理代码AIX 提供了两种不同的代码,它们别离是:IBM AIX®(内部)位置系统代码物理位置代码AIX 内部位置代码可与物理代码配合利用来识别设备,咱们稍后会在本文这了解这种用法。
利用AIX 生成的那些代码引用了某些特定的设备,例如:10-80-00-3,0 SCSI CD Drive10-80-00-2,0 SCSI disk02-08-00 SAS disk上面的代码是访问实际设备的内部途径,能够利用 lsdev 命令来查看它们。
另一个咱们专门感爱好的位置代码是物理类型的,由固件生成。
例如:U789C.001.DQD3F62-P2-D3 SAS Disk Drive自从几年前发布了IBM POWER5 处置器以后,物理位置代码就成了定位设备的首选方式。
作为一项体会法那么,您需要的一般是物理代码。
这也是本文的重点。
表1 中提供的命令使您能够取得有关设备的各类信息。
表1. 取得有关您的设备的信息的命令命令描述lsdev -C -H -F "name status physloc location description"获得AIX(如果存在)和物理位置代码。

d3blocks用法
D3.js是一款强大的JavaScript库,用于在Web浏览器中生成动态、交互式数据可视化。
D3.js利用可扩展矢量图形(SVG)、HTML5和级联样式表(CSS)标准。
D3.js没有特定的“D3.js块”的概念,但有一种名为“D3 Blocks”的特定框架,它是一个用于创建独立的交互式图表的框架。
这个框架允许你使用Python创建D3图表,无需其他依赖项,且创建的图表可以在浏览器中绘制,并可以分享给其他人。
使用D3 Blocks创建图表的基本步骤如下:1.初始化:首先,导入D3模块并创建一个D3对象。
pythonfrom d3blocks import D3Blocksd3 = D3Blocks()2.导入数据:使用import_example方法导入你需要的示例数据集。
pythondf = d3.import_example('climate') # 你可以替换'climate'为你需要导入的示例数据集名称3.创建图表:使用特定的方法创建你需要的图表类型。
以下是几种可用的方法:o timeseries():时间序列图,也被称为趋势图,以时间为横轴,观察变量为纵轴,反映时间与数量之间的关系。
o heatmap():热力图,用于显示数据的热度分布。
o particles():粒子图,可以将任何字体转换成带有动态效果的粒子图。
以下是timeseries()方法的示例代码:pythond3.timeseries(df, datetime='date',dt_format='%Y-%m-%d %H:%M:%S', fontsize=10)4.查看图表:最后,使用showfig参数在浏览器中查看生成的图表。
pythond3.showfig(df)以上步骤仅适用于使用Python和D3 Blocks的情况。
请注意,如果你希望使用D3.js 在浏览器中直接进行图表绘制,可能需要学习和了解更多关于D3.js的API和相关技术。
RAID3和RAID5技术详解
RAID3和RAID5技术详解RAID3和RAID5技术详解热插拔一些面向高端应用的磁盘镜像系统都可以提供磁盘的热插拔功能。
所谓热插拔功能,就是允许用户在不关闭系统,不切断电源的情况下取出和更换损害的硬盘。
如果没有热插拔功能,即使磁盘损坏不会造成数据的丢失,用户仍然需要暂时关闭系统,以便能够对硬盘进行更换。
现在,使用热插拔技术只要简单的打开连接开关或者转动手柄就可以直接取出硬盘,而系统仍然可以不间断的正常运行。
校验RAID 3和RAID 5都分别使用了校验的概念提供容错能力。
简单的说,我们可以把校验想象为一种二进制的校验和,一个可以告诉你其它所有字位是否正确的特殊位。
在数据通信领域,奇偶校验被用来确定数据是否被正确传送。
例如,对于每一个字节,我们可以简单计算数字位1的个数,并在字节内加入附加校验位。
在数据的接收方,如果数字位1的个数为奇数,而我们使用的又是奇数校验的话,则说明该字节是正确的。
同样对偶数校验也是如此。
然而,如果数字位1的个数和校验位的奇偶性不一致的话,则说明数据在传送过程中出现了错误。
RAID系统也采用了相似的校验方法,可以在磁盘系统中创建校验块,校验块中的每一位都用来对其它关联块中的所有对应位进行校验。
在数据通讯领域,虽然校验位可以告诉我们某个字节是否正确,但是无法告诉我们到底是哪一位出现了问题。
这就是说我们可以检测错误,但是不能改正错误。
对于RAID,这是远远不够的。
固然错误的检测非常重要,但是如果不能对错误进行修复,我们就无法提高整个系统的可靠性。
举个例子来说,假设我们发现校验块中第10个字节的第5位不正确。
如果这个校验块包含的是另外8个数据块的校验信息,那么哪一个数据块才是问题的罪魁祸首呢?也许你可能会想为每一个数据块都建立一个校验块就可以解决问题。
但是这种方法很难实现。
事实上,RAID主要是借助磁盘控制器的错误报告检测错误位置,并进行修复。
如果磁盘控制器在读取数据时没有发出任何“抱怨”,那么系统将会视该数据为正确数据,继续使用。

3par存储学习笔记1
在VENTER里导入VSP的OVF模板:导入完成以后,虚拟机配置:1CPU、1GB存,硬盘精简。
启动刚导入的VSP虚拟机:一、3par存储初始化配置:1.配置VSP虚拟机在vCenter里,点击“编辑”—“部署OVF”,通过OVF文件把虚拟机导入并启动,准备配置IP地址:10.1.9.612.开机之后,询问是否进入默认配置选择NO,登陆系统时,用户名root,密码为空,通过下面这个命令配置IP地址:system-config-network –上面命令最后是空格加一个减号,只配置ETH0的IP即可,IP配置完以后,重启网络服务:service network restart3.载入Smart Start在主界面第二项里的第一部分,输入VSP的IP(10.1.9.61)、输入SN,然后等待系统初始化完成,见下图:4.然后执行Smart Start主界面里第二项里的第二部分,输入VSP的IP(10.2.31.148)【图中“1”位置】。
先执行,过程如下:5.在浏览器里,打开VSP,如下:https:// 10.2.31.148登陆权限:用户名:setupusr密码:空提前添加信任站点:再执行:输入VSP的IP地址:打开以后,配置存储的管理地址(10.2.31.149),此存储二个控制器上都有管理口(MGMT),这二个口都需要接到交换机上,这二个口共用同一个管理IP地址。
设置用户名和密码:Username:3paradmPassword:***********二、3par存储概念修改光纤PORT的角色:1.HOST在3par存储里,和其他存储一样,HOST指的是配置有HBA卡的服务器。
2.HOST SET在3par存储,HOST SET可以理解为是一个“主机组”,意思是每个HOST SET里可以包含有多台主机。
3.CPG建议策略命令名按照RAID级别_磁盘类型等信息命名,便于后期使用时快速识别各个CPG的具体配置。

raid3原理
RAID 3是一种RAID(Redundant Array of Independent Disks)技术,它通过把多个磁盘组合在一起作为一个逻辑磁盘进行操作,通过使用奇偶校验盘来保证数据的安全性。
其工作原理如下:
1. 将数据条带化(striping)分布在多个物理磁盘上,每个磁盘存放数据的一部分。
2. 当读取数据时,RAID 3直接从奇偶校验盘读取缺失的数据部分,然后再重新组合以得到完整的数据。
3. 在写入数据时,RAID 3会将数据条带化写入所有的磁盘。
同时,奇偶校验盘也会相应地更新以保持总和正确。
这种方法的优点是实现简单,对读/写请求的响应时间较接近于单独的磁盘。
然而,其缺点也很明显:因为需要维护奇偶校验信息,所以系统性能可能会受到影响;此外,当一个磁盘失效时,需要从其他磁盘中恢复丢失的数据,这可能需要其他硬盘的介入,可能影响系统的整体性能。
因此,RAID 3适用于对数据安全性要求较高,但预算和空间限制较低的情况。
