SAN Client備份測試(SAN Client & NetBackup 5200 & VMware & Deduplication)Version 1.0Arthur Xu2011-04-201 環境介紹VMware SAN & SAN Client & Dedup(5200)這種方式下所有的數據流均通過SAN方式來傳送。1. NBU 5200被配置為FT Media Server2. Backupproxy1配置為SAN Client3. 數據通過Backupproxy1通過SAN讀取后，通過SAN網絡傳送到NBU52004. NBU5200上實現重復數據刪除5. 目前NBU5200已經可以通過手工方式開啟SAN Client支持a) NBU5200近期將實現SAN Client官方支持(GUI界面?)SAN Client方式傳輸有如下特點：1. SAN Client廣泛支持各種類型的OS。2. SAN Client方式下，只能支持Media Server端重復數據刪除。1.1 NBU 5200上手工開啟FT Media Server方法1.1.1 卸載HBA卡驅動rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhbaInstalling nbhba driver. Uninstalled WinDriver for FT Server mode. It may be necessary to temporarily unload your QLogic drivers to free up the ports for the nbhba drivers.This is an optional step. If you choose not to do this, the nbhba drivers may not have access to the HBA ports until a subsequent reboot.Would you like to unload and reload your native QLogic drivers now? y,n (y) Are you sure you want to unload QLogic driver: qla2xxx? y,n (y) Removing qla2xxx. Cannot continue since qla2xxx is in use and cannot be removed. Please release references to qla2xxx before trying the install again.該步驟可能不成功，主要是qla2xxx驅動綁定到內核中了。編輯 /etc/modprobe.conf 注釋掉qla2xxx 模塊rootnetbackup7 boot# cat /etc/modprobe.conf alias eth0 forcedeth alias eth1 forcedeth alias eth2 forcedeth alias eth3 forcedeth alias scsi_hostadapter mptbase alias scsi_hostadapter1 mptsas #alias scsi_hostadapter2 qla2xxx alias scsi_hostadapter3 usb-storage 編輯/etc/modprobe.d/blacklist文件，在文件尾添加 blacklist qla2xxx重啟機器并再次運行nbftsrv_config -nbhba命令檢查是否成功rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbftsrv_config -mode nbhba installed1.1.2 獲得對應的HBA卡WWN號rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbhba -l 1 2432 21:00:00:1B:32:91:E0:F9 QLE2462 0 0 143 2 2432 21:01:00:1B:32:B1:E0:F9 QLE2462 1 0 143 rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbhba -L Card #1 HBA Index #1 Device ID = 2432 World Wide Name = 21:00:00:1B:32:91:E0:F9 Model Name = QLE2462 Port = 0 Mode = initiator (designated for other use)(143) HBA Index #2 Device ID = 2432 World Wide Name = 21:01:00:1B:32:B1:E0:F9 Model Name = QLE2462 Port = 1 Mode = initiator (designated for other use)(143) 1.1.3 設置對應的HBA卡工作在Target方式rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbhba -modify -wwn 21:00:00:1B:32:91:E0:F9 -mode target Modified port with WWN 21:00:00:1B:32:91:E0:F9 通過命令檢查rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbhba -L Card #1 HBA Index #1 Device ID = 2432 World Wide Name = 21:00:00:1B:32:91:E0:F9 Model Name = QLE2462 Port = 0 Mode = target (designated for FT Server)(8142)HBA Index #2 Device ID = 2432 World Wide Name = 21:01:00:1B:32:B1:E0:F9 Model Name = QLE2462 Port = 1 Mode = initiator (designated for other use)(142)1.1.4 完成配置工作rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbftsrv_config Installing the Jungo WinDriver and Fibre Transport Server.
