11、sizek|m|g|t用NetApp System Manager創(chuàng)建一個flexible volume當創(chuàng)建一個flexible volume, 需要預先了解如下參數:Volume nameAggregate nameLanguageSpace guarantee settings 使用命令行創(chuàng)建Flexible Volume以下范例是用命令行創(chuàng)建一個名為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可以使用如下命令來監(jiān)控inode的使用情況:df -i可以使用如下命令開擴展inode的大小:maxfiles網絡端口配置40Etherchannel Trunks (虛擬網口)What is a VIF?聚合多個物理或者虛擬網絡端口到一個虛擬網絡端口下客戶端訪問單個虛擬IP地址41Single-Mode Tru

16、nk42Multi-Mode Trunk43網絡管理虛擬網卡：多個物理端口對應一個虛擬端口(vif, ifgrp)和一個IP地址虛擬網卡綁定模式：Single(standby)Multi(loadbalance)兩種模式。虛擬網卡命令Vif|ifgrp status create | destroy網絡命令：Ifconfig配置文件：/etc/rc/etc/hostsNFS Exporting Resources輸出資源遠程的客戶端需要訪問該資源, 資源必須被輸出永久的export資源:編輯/etc/exports 文件執(zhí)行exportfs p命令 使用NetApp System Manage

17、r可以使用exportfs -i o命令臨時輸出資源/vol/vol0/pubs -rw=host1:host2,root=host1/vol/vol1 -rw=host2/vol/vol0/home添加輸出到/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 命令重新去加載/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命令臨時輸出使用exportfs 命令去創(chuàng)建一個臨時輸出:system exportfs -i -oExample:system exportfs -i -o ro=host1 /vol/vol0/home NOTE: 當存儲重啟后，該配置會消失Exportfs參數顯示所有正在輸出的內容:system exportfs添加輸出到/etc/exports 文件:system exportfs -p options path重新加載/etc/exports 文件:system export

21、fs -r 卸載所有的輸出:system exportfs -uav卸載指定的輸出:system exportfs -u pathSystem Manager: Exporting現有的/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、從一個客戶端mount:通過Telnet或者其他手段登陸到一臺主機上創(chuàng)建一個目錄作為mount點Mount存儲到mount點上登陸mount點執(zhí)行l(wèi)s l確認mount已經生效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系統(tǒng)的監(jiān)控目

23、測:現場首先進行指示燈和LCD面板檢查，判斷是否有異常情況發(fā)生新一代系統(tǒng)使用 System Manager或使用命令行： sysconfig a察看總體硬件狀態(tài)df h 察看卷空間 df A察看Aggregate空間df I 查看卷inode使用情況 vol status r察看是否有空余spare盤environment status 察看是否有環(huán)境問題sysstat xs 1 察看系統(tǒng)性能cf status 察看Cluster狀態(tài)ifconfig a 察看網絡狀態(tài)或使用OnCommand Unified Manager (Operations Manager/DFM)其他支持SNMP的網管

24、平臺59日常檢查整體出錯信息整體容量信息具體Aggr容量信息具體vol容量信息AutoSupportAutoSupportAutoSupport:監(jiān)控存儲系統(tǒng)的操作自動發(fā)信息到Technical SupportAutoSupport 信息在如下情況觸發(fā):當一個觸發(fā)事件發(fā)生時當手動去觸發(fā)時當存儲系統(tǒng)重啟時每周一個定點時間（每周日的0時）E-Mail ServerHTTP/HTTPSAutoSupport事件范例EventsE-Mail Subject LineLow NVRAM batteryBATTERY_LOWDisk failureDISK_FAIL!Disk scrub detected

27、n指定是否希望通過SMTP或者HTTP/HTTPS發(fā)送信息給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手動觸發(fā)AutoSupport手動觸發(fā)AutoSupport, complete the following

28、steps: 在存儲命令行執(zhí)行如下命令: options autosupport.doit messageSystem Manager: AutoSupportTo configureAutoSupportSystem Manager: AutoSupport日志的查看與收集68察看日志收集日志在SecureCRT里面記錄會話日志69收集日志通過rdfile /etc/messages命令即可收集messages文件的內容70SP日志的查看與收集SP日志的收集通過串口登陸后使用ctrl+G命令進入到sp進入到sp中后執(zhí)行events all命令收集環(huán)境信息通過system log命令收集sp系

29、統(tǒng)日志日志收集完畢后通過ctrl+d退出sp到串口72存儲系統(tǒng)監(jiān)控和管理系統(tǒng)監(jiān)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
