(SAN Client & NetBackup 5200 & VMware & Deduplication)

Version 1.0

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SAN方式来传送。 1. NBU 5200被配置为FT Media Server 2. Backupproxy1配置为SAN Client

3. 数据通过Backupproxy1通过SAN读取后，通过SAN网络传送到

NBU5200

4. 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 5200上手工开启FT Media Server方法

1.1.1 卸载HBA卡驱动

[root@netbackup7 ~]# /usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhba

Installing 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.

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

[root@netbackup7 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

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

[root@netbackup7 ~]# /usr/openv/netbackup/bin/admincmd/nbftsrv_config -mode nbhba installed

1.1.2 获得对应的HBA卡WWN号

[root@netbackup7 ~]# /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

[root@netbackup7 ~]# /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 设置对应的HBA卡工作在Target方式

[root@netbackup7 ~]# /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

通过命令检查

[root@netbackup7 ~]# /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

[root@netbackup7 ~]# /usr/openv/netbackup/bin/admincmd/nbftsrv_config

Installing the Jungo 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 each 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, creating...

/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-2.6.18-128.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

[root@netbackup7 ~]# /usr/openv/netbackup/bin/admincmd/nbftsrv_config -mode

Fibre Transport server installed and running.

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：  备份速度快，数据恢复更灵活

 便捷的安装，只需在客户机上安装标准客户端软件  磁盘到磁盘的备份，恢复更加灵活  客户端无需经常升级

 客户端广泛支持各种操作系统平台 Netbackup的SAN Client有部分限制：  FT Media Server端支持Linux和Solaris

 需要把HBA卡设置为Target模式，有严格兼容列表。
