HP StorageWorksEVA4x00/6x00/8x00M5314 drive enclosure installation instructionsThis document contains instructions for addingan M5314drive enclosure to an existingEVA4x00/6x00/8x00storage system cabinet.These instructions are not for adding a drive enclosure to an expansion cabinet.20072007*5697-6937*Adding a drive enclosure to anEVA8x00/6x00This section contains the procedure for adding an M5314drive enclosure to an EVA8x00or EVA6x00while the storage system is operating.The M5314A or M5314B is used with the EVA8000and EVA6000.The M5314C drive enclosure is used with the EVA8100 andEVA6100.HP highly recommends that you perform this upgrade procedureduring off-peakhours.A fully loaded drive enclosure with all components installedweighs more than29.5kg(65lb.)and requires a minimumof two people to move.To safely and easily install the driveenclosure,remove the drives,power supplies,blowers,EMU,and I/O modules.This reduces the drive enclosure weight toapproximately11.0kg(24lb.).Even though a single person canlift this weight,the drive enclosure is difficult to install because ofthe physical size.Therefore,HP recommends that a minimum oftwo people install an empty drive enclosure in a rack.Before you begin this hardware upgrade,you must verify that the Enterprise Virtual Array is functioning e HP Command View EVA to verify that each drive enclosure and disk drive has a good operational status.If a drive enclosure or disk drive does not have a good operational status,correct the problem.1.If it is necessary to add an ID expansion cable to the cabinetaddress bus to accommodate the new drive enclosure,install the cable as follows:a.Remove the top terminator from the cabinet address bus.b.Connect the new ID expansion cable to the address bus.c.Install the top terminator at the end of the new expansioncable.bel each new FC cable with the labels contained in the driveenclosure kit.Each drive enclosure has two FC copper e the labeling scheme described in Table1.Table1FC cable labelsDriveenclosure FC cable labelsDriveenclosure FC cable labels

HP StorageWorks EVA的最佳實例HP 諮詢中心技術經理張明福文關於EVA 的規劃,基本上根據三個因素:Cost, Performance, Availability。
客戶常關心的問題包括:「是否要把全部的硬碟都放在同一disk group或二個(以上) group ? 它們之間的Performance,Availability差異如何?使用不同的VRAID level和硬碟故障保護程度 (disk failure protectionlevel),將佔用多少空間,還是多少可用空間 ? 我使用Oracle資料庫,disk group 和data files,redo logs, archive files等檔案,如何規劃才兼具最佳的可用性 (availability) 和性能(performance)」…等等。
一般說來,考慮某一因素可能就無法顧及其他因素,使用者必須分析自己作業環境的需求和什麼是您最重要的因素,HP工程師會瞭解您的環境和需求而為您作最佳規劃,以下以這三個因素分別舉列其最佳實例供您參考,如果您需要更進一步的資料,可參考HP EVA5000和Storage array systems whitepapers 的網址:/storage/arraywhitepapers.htmlCost Considerations.在一disk group使用相同容量的硬碟.只使用一個 disk group (減少保留空間數量 (reserved space) ).儘可能使用更多的硬碟.使用較低性能、較大容量的硬碟不混合不同容量硬碟在同一disk group:在一個disk group裡,EVA保留二倍(Vriad1) 最大硬碟的空間來rebuild data處理一顆或二顆故障硬碟。
例如:一個disk group有16顆36GB 硬碟,它必須保留 (36GB * 2(failure protection level)* 2) 的空間。

存储日常维护1、EVA系统的开机和关机顺序EVA 作为企业的核心数据存储系统,如何正确的开机和关机对数据安全有着很大的影响。
在日常维护中,请务必按照正确顺序进行开关机。
EVA系统的开机顺序正确的开机顺序为:1、开机柜总电源;2、开光纤交换机电源,开EVA 机柜电源(此时硬盘柜自动加电);3、启动SMA;@4、等待10 分钟待光纤交换机和硬盘柜状态正常后开控制卡电源;5、等待3 分钟待控制卡状态稳定后开主机电源,启动进入操作系统6、起集群服务及应用;、EVA系统的关机顺序正确的关机顺序为:1、停集群服务和节点2、shutdown 服务器;3、通过sma关闭eva的控制卡;>4、关闭eva控制卡后的开关;5、关闭SMA;6、关闭SAN SWITCH;7、关闭EVA机柜电源;关闭控制卡如下图:2、如何配置EVA存储系统>EVA的配置主要有如下步骤:1. 准备相关信息a. 列出需要使用eva存储的主机名、ip等信息.b. 列出所有需连接eva的主机的Fibre Channel adapters (FCAs).c. 查出FCA卡的WWN号.2. 升级相关软件,如command view等(此项为可选项).3. 初始化EVA存储.4. 升级firmware(为可选项)5. 创建disk group.6. 创建主机列表.7. 创建virtual disks.8. 创建 snapshots and snapclones.(需购买相关的license)2.1、初始化 EVA点击初始化图标,eva 将初始化,初始化过程中要求输入存储的名称,如EVA3000/EVA5000 等,该名称将在面板上显示。
初始化会导致所有的数据都会丢失!初始化全过程如下图:;点击initialize:点击Advanced options:如图示选择use managerment appliance date/time:对每个Disk Group来说,都有disk failure保护机制,分别为none, single和double,其中, none表示无spare, single表示留出2disk的空间做spare, double 表示留出4disk空间做spare;如硬盘空间足够大,建议选择double,但至少选择single;comment 内容为可选项。
至此,EVA的初始化完成。
下图为初始化完成后的信息:2.2、创建disk group在创建disk group 要注意每个group 至少需要8 块disk才可以;创建disk group 的过程如下:&点击Create disk group:输入group名称,next:选择disk group中的硬盘数目和protection level:输入alarm level,建议为default值(95%),设好该值后,在分配空间时,不要使用超过可用空间的95%,否则会alarm,该选项主要是在用户数据量大空间不够时提醒用户做扩容等;、2.3、如何浏览和更改组的属性Save changes —保存对该页所做的改动。
Add disks —添加新的物理盘到该group中.Locate —定位组中的某个disk的位置,locate off取消locate动作.Delete —删除组,会删除组内的数据. 不能删除Default Disk Group. 更改disk group name, disk failure protection level, occupancy alarm level, and comments by *entering new values and clicking Save changes.2.4、添加主机2.4.1、准备工作在SAN的架构中,EVA和主机通过SAN交换机相连,主机通过FCA卡访问EVA。
EVA通过command view eva软件允许主机访问相应的disk。
Command View EVA 有以下功能:–创建一个host folder.–添加host.–更改 host 属性:~–添加 FCA.–删除 FCA.–删除 host.在添加主机前,先做如下准备工作:–主机名– IP address (optional)– World Wide ID (WWID) of one FCA– Operating system type!添加主机包括以下:1. Collect the host information listed above.2. Create a host folder (if desired).3. Add a host (to a folder if desired).4. Add more FCAs.5. Verify that the host has been added.我们可以根据需要,随时添加相关主机。
;2.4.2、创建 host folder(此步骤为可选项)我们可以根据需要创建相关的host folder,如根据应用类别或操作系统类别等; Example 在图示中,我们创建了名为 hsv3lab的host folder. The buttons on the Host Folder Properties page launch the following functions:Create folder —创建host folder.Add host —在当前folder中添加host 如需创建host folder, 在 Host Folder Properties页点击Create folder. 步骤: 1. Enter a name —输入host folder的名称.2. 点击 Finish.Example 下例是添加一个host folder的图示2.4.3、添加主机&添加主机的过程如下:点击Add host:输入主机名(该名称为用户自己定义的,不一定与实际主机名相同)IP地址为可选项,可以不输,建议输入,便于识别该主机;选择FCA卡的WWN号和操作系统类型,一台主机可以有多个FCA卡,这样就可以有多条path访问. 每块卡都要添加,且多path时需要购买secure path软件(Tru64 unix系统除外)。
注:在更换FCA卡后,必须要将该卡的WWN号重新添加到该host中。
否则,这条path 无法使用。
;comment内容为可选项2.4.4、如何修改host 的属性可以更改更改以下相关信息:Operating system type, custom type, and direct eventing ,Comments 如需更改其他信息,需要删除该主机再重新添加。
更改完后须点击save changes;这里,暂不演示更改的过程,我们继续浏览别的信息,点击presentation:每个按键的说明如下:Save changes —保存所做的改动、Delete host —删除相应的host。
Move — move当前host到别的目录等.从图中可以看出有哪些disk可以给本主机使用,其lun ID为多少。
点击ports:可以删除或添加port(这里的port就是主机的FCA),特别在更换FCA卡时要更改该项。
"点击add port:2.5、如何创建 vdisk folderEVA可以允许创建类似于host folder的vdisk folder,用来根据用户需要对vdisk 进行区分。
如根据vdisk给不同主机或平台划分等;如欲创建vdisk folder, 点击 Create folder:1. Enter a name —输入vdisk group的名称.)2. 输入comment (optional).3. 点击 Finish.2.6、如何创建 vdisk在同一个Disk Group 里可以划分多个VD,而这些VD的冗余机制可以为Raid0, Raid1, Raid5。
Raid0,stripe,是没有任何冗余的。
任何一个物理磁盘损坏,都会导致数据的丢失。
Raid1,mirror方式。
Raid5,采用4+1 冗余。
EVA采用的为虚拟存储技术,与传统的 raid 技术不同,虚拟raid 所有创建的raid0、>raid1、raid5 是分布在disk group 内的所有disk上。
下图为虚拟存储的raid 示意图:具体创建步骤如下:选择vdsik或其中的某个vdsik folder,点击create vdisk:在navigation pane选中Virtual Disks, 与管理Host类似,可以先生成一个Folder, 来对VD分类。
在Content Pane点击Create Folder, 输入一个名字,点击Finish确定。
在navigation pane选中Folder, 然后在右边点击Create VD Family. 按需要输入VD 的名字,RAID级别,大小等。
OS Unit Id是针对TRU64/VMS系统的,对于HPUX来说不需要更改。
`Present to host, 可以在这里选择某一台可以访问到这个VD的host.Prefer path/mode: 可以选择的方式有:No Preference---------------VDISK随机选择控制卡Path A - Failover Only--------VDISK优先考虑在控制卡A上online。
如A故障,切换到B上,但在A修复后不会failback。
Path B - Failover Only--------VDISK优先考虑在控制卡B上online。
如B故障,切换到A上,但在B修复后不会failback。
Path A -Failover/Failback------ VDISK优先考虑在控制卡A上online。
如A故障,切换到B上,但在A修复后会failback,重新在A上运行。
Path B -Failover/Failback------ VDISK优先考虑在控制卡B上online。
如B故障,切换到A上,但在B修复后会failback,重新在B上运行。
各操作系统对prefer path/mode的支持如下:~点击Next Step, 选择一个LUN ID。
每个VD的LUN ID就是不同的,而对就不同的Host, 同一个VD对就的LUN ID最好是一样的。
点击Finish确定。
点击OK,后台将会对group的disk做leveling,生成VD需要一点时间,取决于这个 VD 的大小。
2.7、如何更改 vdisk属性在左侧选择需要更改的vdisk:¥该页可以修改的选项为cache policies,vdisk大小,写保护等;点击presentation:该页可以修改os id及prefer mode。
