1.环境描述。
1).操作系统版本：
# oslevel -s
2).iSCSI设备：
openfiler x86_64bit 2.3
2.确保AIX服务器与iSCSI存储服务器能够正常的通信。
3.查看AIX服务器相应的iSCSI包。
& & & & IBM从5200-03开始，在操作系统基本包中包含了iscsi的驱动程序：
# lslpp -L | grep -i iscsi
& mon.IBM.iscsi.rte
& & & & & & & & & & & & & & &6.1.1.0 & &C & & F & &Common iSCSI Files
& devices.iscsi.disk.rte & & 6.1.0.0 & &C & & F & &iSCSI Disk Software
& devices.iscsi.tape.rte & & 6.1.0.0 & &C & & F & &iSCSI Tape Software
& devices.iscsi_sw.rte & & & 6.1.1.0 & &C & & F & &iSCSI Software Device Driver
& devices.pci..diag &6.1.0.0 & &C & & F & &IBM 1 Gigabit-TX iSCSI TOE
& devices.pci..rte & 6.1.0.0 & &C & & F & &IBM 1 Gigabit-TX iSCSI TOE
& devices.pci.1410cf02.diag &6.1.0.0 & &C & & F & &1000 Base-SX PCI-X iSCSI TOE
& devices.pci.1410cf02.rte & 6.1.0.0 & &C & & F & &1000 Base-SX PCI-X iSCSI TOE
& devices. & 6.1.1.0 & &C & & F & &Common PCI iSCSI TOE Adapter
& devices.pci..diag &6.1.1.0 & &C & & F & &1000 Base-TX PCI-X iSCSI TOE
& devices.pci..rte & 6.1.0.0 & &C & & F & &1000 Base-TX PCI-X iSCSI TOE
& devices.pci..diag &6.1.0.0 & &C & & F & &IBM 1 Gigabit-SX iSCSI TOE
& devices.pci..rte & 6.1.0.0 & &C & & F & &IBM 1 Gigabit-SX iSCSI TOE
& devices.pci.77102e01.diag &6.1.0.0 & &C & & F & &1000 Base-TX PCI-X iSCSI TOE
& devices.pci.77102e01.rte & 6.1.0.0 & &C & & F & &PCI-X 1000 Base-TX iSCSI TOE
4.编辑客户端target配置文件。
# vi /etc/iscsi/targets
10.0.0.159 3260 iqn..openfiler:tsn.a0712cbb9ca7
格式为：ip port target_iqn
& & & & ip为iSCSI服务器地址，端口是Openfiler默认的3260端口，target_iqn是创建的iqn的名称。
5.扫描iSCSI设备：
# cfgmgr -v -l iscsi0
----------------
attempting to configure device 'iscsi0'
Time: 0 LEDS: 0x25b0
invoking /usr/lib/methods/cfgiscsi -l iscsi0
Number of running methods: 1
----------------
Completed method for: iscsi0, Elapsed time = 1
return code = 0
****************** stdout ***********
****************** no stderr ***********
----------------
Time: 1 LEDS: 0x539
Number of running methods: 0
----------------
attempting to configure device 'hdisk2'
Time: 1 LEDS: 0x25f3
invoking /usr/lib/methods/cfgscsidisk -l hdisk2
Number of running methods: 1
----------------
Completed method for: hdisk2, Elapsed time = 4
return code = 0
****************** no stdout ***********
****************** no stderr ***********
----------------
Time: 5 LEDS: 0x539
Number of running methods: 0
----------------
calling savebase
return code = 0
****************** no stdout ***********
****************** no stderr ***********
Configuration time: 5 seconds
6.查看设备：
hdisk0 & & & & &00cc1ad4ef095bf0 & & & & & & & & & &rootvg & & & & &active
hdisk1 & & & & &00cc1ad46aff307f & & & & & & & & & &rootvg & & & & &active
hdisk2 & & & & &none & & & & & & & & & & & & & & & &None
7.查看hdisk2属性：
# lsattr -El hdisk2
clr_q & & & & no & & & & & & & & & & & & & & & & & & & & Device CLEARS its Queue on error True
host_addr & & 10.0.0.159 & & & & & & & & & & & & & & & & Hostname or IP Address & & & & & False
location & & & & & & & & & & & & & & & & & & & & & & & & Location Label & & & & & & & & & True
lun_id & & & &0x0 & & & & & & & & & & & & & & & & & & & &Logical Unit Number ID & & & & & False
max_transfer &0x40000 & & & & & & & & & & & & & & & & & &Maximum TRANSFER Size & & & & & &True
port_num & & &0xcbc & & & & & & & & & & & & & & & & & & &PORT Number & & & & & & & & & & &False
pvid & & & & &none & & & & & & & & & & & & & & & & & & & Physical volume identifier & & & False
q_err & & & & yes & & & & & & & & & & & & & & & & & & & &Use QERR bit & & & & & & & & & & True
q_type & & & &simple & & & & & & & & & & & & & & & & & & Queuing TYPE & & & & & & & & & & True
queue_depth & 1 & & & & & & & & & & & & & & & & & & & & &Queue DEPTH & & & & & & & & & & &True
reassign_to & 120 & & & & & & & & & & & & & & & & & & & &REASSIGN time out value & & & & &True
rw_timeout & &30 & & & & & & & & & & & & & & & & & & & & READ/WRITE time out value & & & &True
start_timeout 60 & & & & & & & & & & & & & & & & & & & & START unit time out value & & & &True
target_name & iqn..openfiler:tsn.a0712cbb9ca7 Target NAME & & & & & & & & & & &False
& & & & &从上面的结果可以看出，挂载的iSCSI磁盘设备没有reserve_lock和reserve_policy属性，应该可以直接当成共享磁盘使用。

2,检测软件是否已经安装
[root@localhost ~]# rpm -qa |grep iscsi
iscsi-initiator-utils-6.2.0.873-2.0.2.el6.x86_64
[root@localhost ~]#

3,检查ISCSI服务是否启动了和当前级别下的运行情况
[root@localhost ~]# service iscsi status
4，要建立2个文件
[root@localhost ~]# iscsiadm -m iface -Iiscsi_eth0 --op=new
New interface iscsi_eth0 added
[root@localhost ~]# iscsiadm -m iface -Iiscsi_eth1 --op=new
New interface iscsi_eth1 added
[root@localhost ~]#
5.建立iscsi_eth0和eht0的映射关系。同时建立iscsi_eth1和eth1的映射关系.
也可以直接编辑iscsi_eth0和iscsi_eth1文件，把里面的iface.net_ifacename=default改成
iface.net_ifacename=eth0和iface.net_ifacename=eth1即可。
[root@localhost ~]# ls/var/lib/iscsi/ifaces/
iscsi_eth0 iscsi_eth1 iscsi_the0 iscsi_the1
[root@localhost ~]# cd/var/lib/iscsi/ifaces/
[root@localhost ifaces]# ll
-rw------- 1 root root 197 6月 10 16:05 iscsi_eth0
-rw------- 1 root root 197 6月 10 16:06 iscsi_eth1
-rw------- 1 root root 197 4月 3 19:14 iscsi_the0
-rw------- 1 root root 197 4月 3 19:14 iscsi_the1
[root@localhost ifaces]# cat iscsi_eth0
# BEGIN RECORD 6.2.0-873.2.el6
iface.iscsi_ifacename = iscsi_eth0
iface.transport_name = tcp
iface.vlan_id = 0
iface.vlan_priority = 0
iface.iface_num = 0
iface.mtu = 0
iface.port = 0
# END RECORD
[root@localhost ifaces]#
[root@localhost ifaces]# iscsiadm -m iface-I iscsi_eth0 --op=update -n iface.net_ifacename -v eth0
iscsi_eth0 updated.
[root@localhost ifaces]# iscsiadm -m iface-I iscsi_eth0 --op=update -n iface.net_ifacename -v eth0
iscsi_eth0 updated.
[root@localhost ifaces]#
6,重启iscsi服务
[root@localhost ifaces]# service iscsi restart
停止 iscsi： [确定]
正在启动 iscsi： [确定]
[root@localhost ifaces]#
Equallogic配置部分
7.配置Equallogic，映射一个Lun名字为redhat,大小3G的空间
在存储访问网站上，去分配新的磁盘块，这个比较简单，就不截图了，存储设备都会自带一个网址让我们访问的。
Redhat配置部分
8.做discover，可以发现已经看到了redhat的lun。因为有两条路径，所有显示了两行。
[root@localhost ifaces]# iscsiadm -mdiscovery -t sendtargets -p 11.110.10.138:3260

11.因为有多条路径，所有我们需要配置MPIO，查看当前是否安装了MPIO软件。通过查看已经安装了。
[root@localhost ifaces]# rpm -qadevice-mapper
device-mapper-1.02.77-9.el6.x86_64
[root@localhost ifaces]#
[root@localhost ifaces]# chkconfig --listmultipathd
在 multipathd 服务中读取信息时出错：没有那个文件或目录
[root@localhost ifaces]#
12通过查看，MPIO服务在当前级别下没有开，我们启用它。
[root@localhost ifaces]# chkconfig --listmultipathd
multipathd 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
[root@localhost ifaces]#
[root@localhost ifaces]# chkconfigmultipathd on
[root@localhost ifaces]#
[root@localhost ifaces]#
[root@localhost ifaces]# chkconfig --listmultipathd
multipathd 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
[root@localhost ifaces]#
14.我们需要找到/etc/multipath.conf文件中的如下3行，把前面加上#把他们注释掉。
# Blacklist all devices by default. Removethis to enable multipathing
# on the default devices.
blacklist {
devnode &*&
15.重启multipathd服务，通过查看，可以看到我们做的那个3G的LUN信息了。
[root@localhost ifaces]# service multipathd restart
正在关闭multipathd 端口监控程序： [失败]
正在启动守护进程multipathd：/sbin/multipathd: error while loading shared libraries:libsysfs.so.2: cannot open shared object file: No such file or directory
[root@localhost ifaces]#
在/etc/ld.so.conf中加一行/usr/local/lib，.然后运行/sbin/ldconfig，文件解决，
[root@localhost ifaces]# find / -namelibsysfs.so.2
[root@localhost ifaces]#
没有此文件，所以yum安装下
[root@localhost ifaces]# yum install -ylibsysfs*
[root@localhost ifaces]# service multipathd restart
正在关闭multipathd 端口监控程序： [失败]
正在启动守护进程multipathd：/sbin/multipathd: error while loading shared libraries:libreadline.so.5: cannot open shared object file: No such file or directory
[root@localhost ifaces]#
需要安装 readline-5.2.tar.gz，地址为：/s/1jGnFN3S
tar-xvf readline-5.2.tar.gz
cdreadline-5.2
./configure
makeinstall
[root@localhost ifaces]# yum install -ylibreadline*
去/etc/ld.so.conf添加进lib目录即可
[root@localhost readline-5.2]# cp/etc/ld.so.conf /etc/ld.so.conf.backup
[root@localhost readline-5.2]# vim/etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib
[root@localhost readline-5.2]# ldconfig
[root@localhost readline-5.2]#
[root@localhost readline-5.2]#
[root@localhost readline-5.2]# servicemultipathd restart
正在关闭multipathd 端口监控程序： [失败]
正在启动守护进程multipathd： [确定]
[root@localhost readline-5.2]#
[root@localhost readline-5.2]# multipathd-ll
[root@localhost readline-5.2]#
？why？这里没有别的信息呢？为什么没有显示出新分配的那个磁盘的信息呢？
16.继续编辑/etc/multipath.conf,我们给这个3G的LUN起个可以自己命名的名字。
通过multipath &ll,我们可以得到这个3G LUN的WWID: 360c090c2f903ac4a89c2e
把如图前面的#去掉，同时把wwid改成360c090c2f903ac4a89c2e。Alias改成 pddata3.
multipaths {
multipath {
alias pddata3
path_grouping_policy multibus
path_checker readsector0
path_selector &round-robin 0&
failback manual
rr_weight priorities
no_path_retry 5
17.重启multipathd服务，可以看到我们命名的pddata3出来了。
service multipathd restart
why ? 没有看到pddata3
19.格式化 pddata3
[root@localhost readline-5.2]# ls /dev/sdp
[root@localhost readline-5.2]#
ext3太土鳖了，所以采用xfs文件格式
[root@localhost readline-5.2]# yum install-y xfsprogs
[root@localhost readline-5.2]# sudo fdisk/dev/sdp
Device contains neither a valid DOSpartition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with diskidentifier 0xd45833b8.
Changes will remain in memory only, untilyou decide to write them.
After that, of course, the previous contentwon't be recoverable.
Warning: invalid flag 0x0000 of partitiontable 4 will be corrected by w(rite)

接下来，格式化分区为XFS，使用mkfs.xfs命令。如果已有其他文件创建在此分区，必须加上&-f&参数来覆盖它。
[root@localhost readline-5.2]# sudo mkfs.xfs-f /dev/sdp1
meta-data=/dev/sdp1 isize=256 agcount=4, agsize= blks
= sectsz=512 attr=2, projid32bit=1
data = bsize=4096 blocks=,imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=102400,version=2
= sectsz=512 sunit=0 blks,lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
[root@localhost readline-5.2]#
18，建立新目录/pddata3，以此挂载新的磁盘
至此你已经准备好格式化后分区来挂载。假设/pddata3 是XFS本地挂载点。使用下述命令挂载：
sudomount -t xfs /dev/sdp1 /pddata3
[root@localhost readline-5.2]# mkdir/pddata3
[root@localhost readline-5.2]# sudo mount -t xfs /dev/sdp1 /pddata2
[root@localhost readline-5.2]#
[root@localhost readline-5.2]# df -h
