检查网络是否通畅：
[root@rac3 ~]# ping rac1
PING rac1 (192.168.90.2) 56(84) bytes of data.
64 bytes from rac1 (192.168.90.2): icmp_seq=1ttl=64 time=0.614 ms

2 packets transmitted, 2 received, 0% packet loss,time 1000ms
rtt min/avg/max/mdev = 0.169/0.391/0.614/0.223 ms
4. 配置OS级别 内核参数
这里显示的都是要添加的参数，原来的都不要动！！！
[root@rac3 ~]# cat /etc/sysctl.conf
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
/sbin/sysctl –p 生效一下
[root@rac3 ~]# cat /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
[root@rac3 ~]# cat /etc/pam.d/login
session required pam_selinux.so open
[root@rac3 ~]# cat /etc/profile
if [ $USER = oracle ]; then
if [ $SHELL = /bin/ksh ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
5. 检查所需要的rpm是否都在,没有的话具体安装
[root@rac3 ~]# rpm -q binutils compat-dbcontrol-center gcc gcc-c++ glibc glibc-common libstdc++ libstdc++-devel make
binutils-2.17.50.0.6-14.el5
compat-db-4.2.52-5.1
control-center-2.16.0-16.el5
gcc-4.1.2-50.el5
gcc-c++-4.1.2-50.el5
glibc-2.5-58
glibc-common-2.5-58
libstdc++-4.1.2-50.el5
libstdc++-devel-4.1.2-50.el5
make-3.81-3.el5
二． 开始配置Openfiler存储
用节点3打开火狐配置：
配置略。。。就是加了一个rac3的MAPPING
2.1 在节点3上发现存储 如果没有返回值 重启一下Linux
[root@rac3 ~]# iscsiadm --mode discoverydb --typesendtargets --portal 192.168.90.8 --discover
192.168.90.8:3260,1 rac3
[root@rac3 ~]#
[root@rac3 ~]#
[root@rac3 ~]# iscsiadm --mode node --targetnamerac3 192.168.90.10:3260 --login
Logging in to [iface: default, target: rac3,portal: 192.168.90.8,3260]
Login to [iface: default, target: rac3, portal:192.168.90.8,3260] successful.
2.2 配置开机启动规则
[root@rac3 ~]# cat /etc/udev/rules.d/60-raw.rules
# Enter raw device bindings here.
#
# An example would be:
# ACTION=="add", KERNEL=="sda", RUN+="/bin/raw/dev/raw/raw1 %N"
# to bind /dev/raw/raw1 to /dev/sda, or
# ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# to bind /dev/raw/raw2 to the device with major 8,minor 1.
ACTION=="add",KERNEL=="/dev/sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="17", RUN+="/bin/raw /dev/raw/raw1 %M %m"
ACTION=="add",KERNEL=="/dev/sdc1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="33", RUN+="/bin/raw /dev/raw/raw2 %M %m"
ACTION=="add",KERNEL=="/dev/sdd1", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="49", RUN+="/bin/raw /dev/raw/raw3 %M %m"
ACTION=="add",KERNEL=="/dev/sde1", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="65", RUN+="/bin/raw /dev/raw/raw4 %M %m"
ACTION=="add",KERNEL=="/dev/sdf1", RUN+="/bin/raw /dev/raw/
