3、TPG. System Manager(web-based; GUI)管理方法存储系统可以通过以下方式进行管理:命令行接口(CLI)直接访问 (通过串口线直接连接)远程访问 (SSH, Telnet)图形化接口(GUI)远程访问命令行界面Console线连接 Console允许通过以下方式进行连接:串口Serial Port存储包含一个RJ45端口，在后面板标记为（IOIOI ）的样子 通过DB9端口连接到主机的串口 属性:Speed: 9600 bits per secondData bits: 8Stop bits: 1Parity: NoneFlow Control: Hardware

4、or noneData ONTAP 8.0远程访问除了Console直接访问，管理也可以通过以下方式进行远程访问:e0M (if available)Management LANRLMe0Me0ae0bDataLAN远程访问除了Console直接访问，管理也可以通过以下方式进行远程访问:e0M (if available)Ethernet 缺省设置, 使用安全协议: SSH其他不安全协议(不推荐): RSH Telnet命令行界面通过Console和远程访问使用CLI的形式如下：system Wed Apr 7 20:53:01 .logged in from consolesystem缺省配

5、置中, 一个存储允许如下情况:一个会话同一时间只有一个用户 如果创建多余的其他会话会出现报警:Too many users logged in! Please try again later.

9、es (不建议)其他类型的卷，例如：SnapLock volumes and FlexClone volumesFlexible Volumes（精灵卷）Flexible volumes作为逻辑设备进行管理多个flexible volumes可以包含在单个 aggregate中aggr1FlexVol 1FlexVol 2aggr1Aggregates and FlexVol Volumes（精灵卷）Create RAID GroupsCreate aggregate作为aggregate创建的结果RAID groups同时被创建出来Create FlexVol WAFL allocates

10、aggregate space as data is writtenAggregateRG1RG2RG3FlexVol 1FlexVol 2FlexVol 3vol1vol2vol3FlexVol性能的提升I/O 性能:条带化致使aggregate上所有volumes的性能都享受所有硬盘的性能Space利用率:不需要预分配空间空闲的空间可以被回收用于创建新volume或者扩大已使用的volumesVol 1Vol 2Vol 3Vol 4Free创建Flexible Volume用命令行创建一个flexible volume:system vol create volname aggrname

11、sizek|m|g|t用NetApp System Manager创建一个flexible volume当创建一个flexible volume, 需要预先了解如下参数:Volume nameAggregate nameLanguageSpace guarantee settings 使用命令行创建Flexible Volume以下范例是用命令行创建一个名为test的20G大小的包含在aggr0中的volume:system vol create test aggr0 20GCreates a flexible volume called test in aggr020G in sizeagg

15、n)SizeOwner, group, permissionsPointer to xinode (ACLs)Complete file data if the file is 64 bytes or lessPointers to data blocksManaging Inodes可以使用如下命令来监控inode的使用情况:df -i可以使用如下命令开扩展inode的大小:maxfiles网络端口配置40Etherchannel Trunks (虚拟网口)What is a VIF?聚合多个物理或者虚拟网络端口到一个虚拟网络端口下客户端访问单个虚拟IP地址41Single-Mode Tru

16、nk42Multi-Mode Trunk43网络管理虚拟网卡：多个物理端口对应一个虚拟端口(vif, ifgrp)和一个IP地址虚拟网卡绑定模式：Single(standby)Multi(loadbalance)两种模式。虚拟网卡命令Vif|ifgrp status create | destroy网络命令：Ifconfig配置文件：/etc/rc/etc/hostsNFS Exporting Resources输出资源远程的客户端需要访问该资源, 资源必须被输出永久的export资源:编辑/etc/exports 文件执行exportfs p命令 使用NetApp System Manage

17、r可以使用exportfs -i o命令临时输出资源/vol/vol0/pubs -rw=host1:host2,root=host1/vol/vol1 -rw=host2/vol/vol0/home添加输出到/etc/exportsSpecifies the full path to the directory that is exportedAll hosts can mount the /vol/vol0/home directory as read-write if an option is not specifiedThis option gives read-write permi

18、ssions to host2 only. All other hosts have no accessThis option gives host1s root user has root accessThe first option is listed following a dash. Additional options are separated by commas. In this example the -rw option allows host1 and host2 to mount the pubs directory. Host names are listed sepa

19、rated by colons在添加Exports到/etc/exports后, 使用exportfs -a 命令重新去加载/etc/exports文件system rdfile /etc/exports#Auto-generated by setup Mon Apr 30 08:32:21 GMT 2007/vol/flexvol/qtree -sec=sys,rw=2/vol/vol0/home -sec=sys,rw,root=2,nosuidsystem exportfssystem exportfs -asystem exportfs/vol/flexvol/qtree -sec=s

20、ys,rw=2/vol/vol0/home -sec=sys,rw,root=2,nosuidExportfs命令临时输出使用exportfs 命令去创建一个临时输出:system exportfs -i -oExample:system exportfs -i -o ro=host1 /vol/vol0/home NOTE: 当存储重启后，该配置会消失Exportfs参数显示所有正在输出的内容:system exportfs添加输出到/etc/exports 文件:system exportfs -p options path重新加载/etc/exports 文件:system export

21、fs -r 卸载所有的输出:system exportfs -uav卸载指定的输出:system exportfs -u pathSystem Manager: Exporting现有的/etc/exports文件配置exportsSystem Manager: Exporting System Manager: Exporting (Cont.)System Manager: Exporting (Cont.)System Manager: ExportingSystem Manager: Exporting 新exportNFS MountingMounting From a Client

22、从一个客户端mount:通过Telnet或者其他手段登陆到一台主机上创建一个目录作为mount点Mount存储到mount点上登陆mount点执行ls l确认mount已经生效telnet 0 (1)#mkdir /system-vol1-qt1 (2)mount system:/vol/vol1/qtree1 /system-vol1-qt1 (3)cd /system-vol1-qt1 (4)#ls l (5)-rwxr-xr-x root 719634 FEB 11 2004 ,general-rwxr-xr-x root 719634 FEB 13 2004 ,policy系统的监控目

23、测:现场首先进行指示灯和LCD面板检查，判断是否有异常情况发生新一代系统使用 System Manager或使用命令行： sysconfig a察看总体硬件状态df h 察看卷空间 df A察看Aggregate空间df I 查看卷inode使用情况 vol status r察看是否有空余spare盘environment status 察看是否有环境问题sysstat xs 1 察看系统性能cf status 察看Cluster状态ifconfig a 察看网络状态或使用OnCommand Unified Manager (Operations Manager/DFM)其他支持SNMP的网管

24、平台59日常检查整体出错信息整体容量信息具体Aggr容量信息具体vol容量信息AutoSupportAutoSupportAutoSupport:监控存储系统的操作自动发信息到Technical SupportAutoSupport 信息在如下情况触发:当一个触发事件发生时当手动去触发时当存储系统重启时每周一个定点时间（每周日的0时）E-Mail ServerHTTP/HTTPSAutoSupport事件范例EventsE-Mail Subject LineLow NVRAM batteryBATTERY_LOWDisk failureDISK_FAIL!Disk scrub detected

26、 partnerCLUSTER TAKEOVER COMPLETEUnsuccessful cluster takeoverCLUSTER TAKEOVER FAILEDCluster takeover of virtual filerREBOOT (CLUSTER TAKEOVER)Cluster giveback occurredCLUSTER GIVEBACK COMPLETE命令行配置AutoSupport指定是否希望发送信息给NetApp (NetApp Support services):system options autosupport.support.enable off|o

27、n指定是否希望通过SMTP或者HTTP/HTTPS发送信息给NetApp:system options autosupport.support.transportIf smtp, then sent to autosupport.support.toIf http/https, then sent to autosupport.support.urlNOTE: AutoSupport logs are stored here: /etc/log/autosupportRead-only手动触发AutoSupport手动触发AutoSupport, complete the following

28、steps: 在存储命令行执行如下命令: options autosupport.doit messageSystem Manager: AutoSupportTo configureAutoSupportSystem Manager: AutoSupport日志的查看与收集68察看日志收集日志在SecureCRT里面记录会话日志69收集日志通过rdfile /etc/messages命令即可收集messages文件的内容70SP日志的查看与收集SP日志的收集通过串口登陆后使用ctrl+G命令进入到sp进入到sp中后执行events all命令收集环境信息通过system log命令收集sp系

29、统日志日志收集完毕后通过ctrl+d退出sp到串口72存储系统监控和管理系统监控df hfas3050cl1-cn3* df -hFilesystem total used avail capacity Mounted on/vol/vol0/ 90GB 2909MB 87GB 3% /vol/vol0/vol/vol0/.snapshot 22GB 673MB 22GB 3% /vol/vol0/.snapshot/vol/vol9/ 800MB 256KB 799MB 0% /vol/vol9/df Ifas3050cl1-cn3* df -iFilesystem iused ifree
