1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-dateSAN-Client备份设置SAN-Client备份设置SAN Client备份测试(SAN Client & NetBackup 5200 & VMware & Deduplication)Version 1.0Arthur Xu2011-04-20-1 环境介绍VMware SAN & SAN Client & Dedup(5200)这种方式下所有的数据流均通过S

2、AN方式来传送。1. NBU 5200被配置为FT Media Server2. Backupproxy1配置为SAN Client3. 数据通过Backupproxy1通过SAN读取后，通过SAN网络传送到NBU52004. NBU5200上实现重复数据删除5. 目前NBU5200已经可以通过手工方式开启SAN Client支持a) NBU5200近期将实现SAN Client官方支持(GUI界面?)SAN Client方式传输有如下特点：1. SAN Client广泛支持各种类型的OS。2. SAN Client方式下，只能支持Media Server端重复数据删除。1.1 NBU 520

3、0上手工开启FT Media Server方法1.1.1 卸载HBA卡驱动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

4、 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 ql

5、a2xxx is in use and cannot be removed. Please release references to qla2xxx before trying the install again.该步骤可能不成功，主要是qla2xxx驱动绑定到内核中了。编辑 /etc/modprobe.conf 注释掉qla2xxx 模块rootnetbackup7 boot# cat /etc/modprobe.conf alias eth0 forcedeth alias eth1 forcedeth alias eth2 forcedeth alias eth3 forcedeth

6、alias scsi_hostadapter mptbase alias scsi_hostadapter1 mptsas #alias scsi_hostadapter2 qla2xxx alias scsi_hostadapter3 usb-storage 编辑/etc/modprobe.d/blacklist文件，在文件尾添加 blacklist qla2xxx重启机器并再次运行nbftsrv_config -nbhba命令检查是否成功rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbftsrv_config -mode nbhba

7、 installed1.1.2 获得对应的HBA卡WWN号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 = 2

9、/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 通过命令检查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

10、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 Ju

11、ngo WinDriver and Fibre Transport Server. Uninstalled WinDriver for FT Server mode. Removing ql2300_stub. The following automatic startup and shutdown scripts (respectively) have been installed. They will cause the NetBackup Fibre Transport Server daemon to be automatically shut down and restarted e

12、ach time the system boots. /etc/rc.d/rc2.d/S21nbftserver /etc/rc.d/rc3.d/S21nbftserver /etc/rc.d/rc5.d/S21nbftserver /etc/rc.d/rc0.d/K03nbftserver /etc/rc.d/rc1.d/K03nbftserver /etc/rc.d/rc6.d/K03nbftserver Installed driver for FT Server mode. /etc/udev/rules.d/50-windrvr.rules does not exist, creat

13、ing. /etc/udev/rules.d/50-windrvr.rules updated with Jungo WinDriver permissions. Installed WinDriver for FT Server mode. NetBackup Fibre Transport Server started. Would you like to make these changes persist after a reboot? y,n (y) Running mkinitrd. Previous initrd image is saved at /boot/initrd-2.

14、6.18-128.el5.img.08-11-10.11:29:34.删除原来对/etc/modprobe.conf的qla2xxx的注释删除对/etc/modprobe.d/blacklist中添加的blacklist qla2xxx重新启动 检查FT服务是否启动rootnetbackup7 # /usr/openv/netbackup/bin/admincmd/nbftsrv_config -mode Fibre Transport server installed and running.1.2 SAN Client配置1.2.1 发现FT设备NBU Media Server NB520

15、0上显示Fiber Transport Device客户端发现对应设备1.2.2 配置Service手工启动SAN Client FT Service1.2.3 NBU中配置检查SAN Clients中列出对应的服务器1.3 配置SAN Client 传输SAN Client配置Master服务器配置1.4 备份速度和NBU5200 Dedup性能备份速度为135M，接近所用存储的最高性能NBU 5200 CPU利用率2 总结2.1 强大的FT / SAN Client 方式备份和恢复SAN 客户端是一种 NetBackup 高级功能，可完成 NetBackup 客户端的高速备份和还原。备份和

16、还原流量发生在 SAN 上，而 NetBackup 服务器和客户端管理流量发生在LAN 上。它使用光纤通道和 SCSI 命令协议的子集通过 SAN（而不是使用 TCP/IP 通过 LAN）来移动数据。它在 NetBackup 客户端与 NetBackup 介质服务器之间提供一种高性能的传输机制。光纤传输支持多个并行的逻辑连接。支持光纤传输的 NetBackup 系统包含专用于FT 通信的光纤通道 HBA。Netbackup的SAN Client有如下优点：l 备份速度快，数据恢复更灵活l 便捷的安装，只需在客户机上安装标准客户端软件l 磁盘到磁盘的备份，恢复更加灵活l 客户端无需经常升级l 客户端广泛支持各种操作系统平台Netbackup的SAN Client有部分限制：l FT Media Server端支持Linux和Solarisl 需要把HBA卡设置为Target模式，有严格兼容列表。
