DS3400V7000迁移oracle 10G.docx

1、DS3400V7000迁移oracle 10GDS3400迁移到V7000(redhat 4.7+oracle 10G RAC)一、备份2个raw设备rootnode1 # dd if=/dev/raw/raw1 of=/root/raw12096753+0 records in2096753+0 records outrootnode2 # dd if=/dev/raw/raw2 of=/root/raw22096753+0 records in2096753+0 records out二、关闭rac所有节点，连接SAN交换机，划分zone，DS3400存储的光纤连接和SVC的光纤连接划为一

2、个zone，主机和SVC划分一个zone三、SVC接管DS3400存储，导入为临时存储池DS3400存储更改Mapping为SVCSVC检测DS3400存储硬盘导入后的结果四、所有RAC节点开机，SVC创建主机，映射硬盘五、redhat 4 系统卸载DS3400 多链路软件RDAC在RDAC目录运行make uninstall,修改/boot/grub/menu.lst，重启动系统识别存储硬盘#boot=/dev/sdadefault=0timeout=5splashimage=(hd0,0)/grub/splash.xpm.gzhiddenmenutitle Red Hat Enterpri

3、se Linux AS (2.6.9-78.ELsmp) root (hd0,0) kernel /vmlinuz-2.6.9-78.ELsmp ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.9-78.ELsmp.img（initrd /mpp-2.6.9-78.ELsmp.img）title Red Hat Enterprise Linux AS-up (2.6.9-78.EL) root (hd0,0) kernel /vmlinuz-2.6.9-78.EL ro root=LABEL=/ rhgb quiet initrd /initrd-2

4、.6.9-78.EL.img六、配置SVC 多链路，修改raw设备对应关系1、安装linux多链路软件device-mapper device-mapper-multipath.查看rpm qa |grep mapperrootnode1 # rpm -qa |grep mapperdevice-mapper-1.02.25-2.el4device-mapper-multipath-0.4.5-31.el4device-mapper-1.02.25-2.el42、修改/etc/multipath.confdefaults polling_interval 30 failback immedia

5、te no_path_retry queue rr_min_io 100 path_checker tur user_friendly_names yes # SVC device vendor IBM product 2145 path_grouping_policy group_by_prio prio_callout /sbin/mpath_prio_alua /dev/%n 操作步骤：rootnode1 etc# cp multipath.conf multipath.conf.bakrootnode1 etc# rm multipath.confrm: remove regular

6、file multipath.conf? yrootnode1 etc# vi multipath.confdefaults polling_interval 30 failback immediate no_path_retry queue rr_min_io 100 path_checker tur user_friendly_names yes # SVC device vendor IBM product 2145 path_grouping_policy group_by_prio prio_callout /sbin/mpath_prio_alua /dev/%n 3、设置开机启动

7、mapper，重启动系统chkconfig multipathd onchkconfig -level 345 multipathd on查看设备multipath llrootnode2 # multipath -llmpath2 (3600507680281866b000000000000009b)size=10 GBfeatures=1 queue_if_no_pathhwhandler=0_ round-robin 0 prio=200active _ 6:0:2:2 sdah 66:16 activeready _ 6:0:3:2 sdam 66:96 activeready _ 5

12、vices/dev/raw/raw1 /dev/mapper/mpath0p1/dev/raw/raw2 /dev/mapper/mpath1p1/dev/raw/raw3 /dev/mapper/mpath2p1/dev/raw/raw4 /dev/mapper/mpath3p1/dev/raw/raw5 /dev/mapper/mpath4p1如果启动后权限更改，修改/etc/rc.localrootnode2 # cat /etc/rc.local #!/bin/sh# This script will be executed *after* all the other init scr

13、ipts.# You can put your own initialization stuff in here if you dont# want to do the full Sys V style init stuff.touch /var/lock/subsys/localchown oracle:oinstall /dev/raw/raw1chown oracle:oinstall /dev/raw/raw2chown oracle:oinstall /dev/raw/raw3chown oracle:oinstall /dev/raw/raw4chown oracle:oinsta

14、ll /dev/raw/raw5chown oracle:oinstall /dev/raw/raw6chown oracle:oinstall /dev/raw/raw7chown oracle:oinstall /dev/raw/raw8chown oracle:oinstall /dev/raw/raw9chown oracle:oinstall /dev/raw/raw10chmod 777 /dev/raw/raw1chmod 777 /dev/raw/raw2chmod 777 /dev/raw/raw3chmod 777 /dev/raw/raw4chmod 777 /dev/raw/raw5chmod 777 /dev/raw/raw6chmod 777 /dev/raw/raw7chmod 777 /dev/raw/raw8chmod 777 /dev/raw/raw9chmod 777 /dev/raw/raw10七、svc配置磁盘镜像,镜像完成后拆分镜像，使用新存储的磁盘镜像完成后，拆分镜像，使用新存储硬盘使用新的存储硬盘
