常用磁盘阵列运维维护操作指南1、磁盘列阵使用的技术1. 1电源控制(KeyContro)运用MoSFET控制提供给设备的电源，避免硬盘在启动的瞬间因电流过大而影响到系统电源供应系统。1.2 电源延时启动(W0KeyControlSCA)利用延迟时间装当硬盘盒做热拔插功能时，在插入硬盘后，延迟3-4秒后，再将电源送到硬盘以确保硬盘己经在完全就绪的状态下再启动，除可保护硬盘本身的安全外亦可减少插入时的杂讯而造成系统宕机.1.3 过载保护使用自复式保险丝当设备消耗电流过大时，5V(2.5A)12V(35A)将暂时切断送到设备的电源，特错误状态消失后，即自动再接上电源。1.4 风扇侦测可侦测冷却风麝的运转状态，若风扇不转或转速太慢，则产生告声，并可利用按扭将声音清除。15温度侦测设定温度点，如:50飞或60C当温度上升到设定温度时，财产生告信号。16风扇控制结合温度侦测系统，温度上升则提高风扇的转速，以增加风腐的使用寿命。1.7 电压侦测设定电压的上、下限，当供给电压在不正常范围内则产生告信号。2、操作指南磁盘阵列提供两种设定方式：1、直接控制面板设定2、超级终端这里我们介绍的是通过超级终端的设定，将磁盘阵列的串口与主机相连，启动终端程序.ACCSTOR磁盘阵列串口速率的默认配C是38400o每秒位数:38400数据位:0奇偶校验:无停止位：1数据流控制:硬件/无CTRL+L 激活，选择 Terminal(VT100 MOde)进入.2.1快速创建I< Ha:Ln MenU ;<Xck IrwtallationI viev and edit Logical drive - view and edit view and edit view and edit view and edit view and edit view and edit syste> FunctionsI view SySteJn InforaationI view and edit Event logslogical Volua s Bost Iuns Drives chaimelS Configuration parameters Peripheral devices如图,在Quick installation中快速创建你的RAlD,选择你想要的RAID 级别,然后同车 即叮创建.Quick installation只能为你创建一组RAID,即把阵列中所有的硬盘组成一个RAID. 快速创建之后你可以直接在服务器中看到该RAID.2. 2 手动创建 RAlD (view and edit LogicaI dr i ves)在VieW and edit Logical drives中手动创建RAID.按回车进入，当没有做RAID的时候 会弹出一个空的表格,回车后弹出提示“Create Logical DriVe?”，选择YES进入，选择RAID 级别进入，这是会弹出阵列中各个硬盘的信息.如图：LG I ID ' M I RAID Size() I Status I 2 3 jRAID 5ItFLlISlotISiZe(IB)SpeedILe-DRyStatusNendOrandProduct11*1I238469300MBNoHEFRMTDRVSeagateST3250824后2II2I238469300MBNONEFRMlDRVSenateST3250824HS3II3I238469300MBNOHEFRMTDRVSea<ateST3250824MS4IIql238469300MBNONEFRMTDRV配奖ateST3250824HSIIIII回车选中要做RAID的硬盘,然后按ESCLGI11>+MIRAIDSize(三)Status12t1NOIfE1IaX工muDrlVeCaPaeity:238214MBAssignSpareDrivesIDiskReservedSpace:256MBILogicalDriveAssigrmentsIIritePolicy:Default(Write-Back)卜一Initializelode:On-LineIStripeSize:DefaUlt(128KBytes)选择YES创建完毕。2.3分卷GUUD IlPartition logical drive LG I D ' LV I RAID ISize(MB) I SUtuSIl2 B D C ,Ul *SB *FL Ir- IIvefdrivesDeIeteIOglCaldrive1 logicaldriveBaneIIIOglCaldriveassgn>entS1 InitializeprogressIreGenerateparitycpyandreplacedriveIIvritePoliCYdrive,根据自己的需求划分若干个卷。按回车选择做好的RAID,选择PartitionIogica如上图，我们将该RAID分成了200000MB和276428MB两个卷.2.4映射(VieWandeditHostIuns)在手动做完RAID之后我们要通过映射才可以在服务器上找到我们的RAID.进入VieWandeditHOStIUnS,会弹出CHo和CHl两个通道,假如我们把服务器接到了CHo上,那么我们就要在CHO.上做映射,回车进入,选择LogicaIDrive进入，弹出空白的表格按回车,会弹出你已经创建的RAID,如图： aan aenu / dnck installationview and edit Logical drives view and edit logical VOluMeSLUN LVLD DRV Partition Size(KB) RAID 卜+HLG I ID MMRAlDISiZe(MB)I Status 1 2 f3 0 C |#LH 8SB |»FL +÷-+-+÷一476428 GoOD INAMEI view systen InformationI view and edit Event logs回车选择要映射的分区。I < lain enu z -fc-I Quick installationI view and edit Logical drivesI view and edit logical VolumesLun Iv/LD DRV Partition Size(IB) I RAIDoLG I ID ILVlRAIDISiZe(HB)I StatuSli2 B t> C WLN #SBkFLlNAME回车选择MaP Host LUN,选择YES.映射完毕。这是在右边的栏目里我们可以找到刚才 映射的那个分区。4 Main Menu ;
