一、配置存储服务器

1、安装：targetcli

sudo apt-get install targetcli

2、加载模块

root@rocky:/mnt# lsmod |grep configfs
configfs               36864  4 iscsi_target_mod,libcomposite,target_core_mod
root@rocky:/mnt# modprobe configfs

#如果加载模块后没有自动挂载上，执行以下命令手动挂载：
mount -t configfs configfs /sys/kernel/config

3、配置configfs开机自动挂载

vi /etc/fstab
configfs /sys/kernel/config configfs defaults 1 1

4、配置hba驱动

root@rocky:~# vi /etc/modprobe.d/qla2xxx.conf
options qla2xxx qlini_mode="disabled"
root@rocky:~# modprobe qla2xxx
root@rocky:~# sudo update-initramfs -u -k all
update-initramfs: Generating /boot/initrd.img-4.4.0-21-generic
root@rocky:~# sudo reboot

5、查看每台服务器的wwn号

cat /sys/class/fc_host/host*/port_name | sed -e s/0x// -e 's/../&:/g' -e s/:$//

6、运行targetcli

#使用root用户执行
root@rocky:~# targetcli
targetcli 3.0.pre4.1~ga55d018 (rtslib 3.0.pre4.1~g1b33ceb)

All rights reserved.
#执行targetcli，ls后显示qla2xxx即为正常

7、创建iblock

/> cd backstores
/backstores> iblock/ create name=linx_disk1 dev=/dev/sda6
Created iblock storage object linx_disk1 using /dev/sda6.
/backstores> ls
o- backstores ................................................................................................................ [...]
  o- fileio ..................................................................................................... [0 Storage Object]
  o- iblock ..................................................................................................... [1 Storage Object]

  o- pscsi ...................................................................................................... [0 Storage Object]
  o- rd_mcp ..................................................................................................... [0 Storage Object]

8、创建wwn

/backstores> cd ..
/> qla2xxx/ create 50:01:43:80:03:af:dd:d8
/> cd qla2xxx/50:01:43:80:03:af:dd:d8/
/qla2xxx/50:0...0:03:af:dd:d8> ls
o- 50:01:43:80:03:af:dd:d8 ............................................................................................... [enabled]
  o- acls ................................................................................................................. [0 ACLs]
  o- luns ................................................................................................................. [0 LUNs]

9、创建luns

qla2xxx/50:0...0:03:af:dd:d8> luns/ create /backstores/iblock/linx_disk1 
Selected LUN 0.
Created LUN 0.
/qla2xxx/50:0...0:03:af:dd:d8> ls
o- 50:01:43:80:03:af:dd:d8 ............................................................................................... [enabled]
  o- acls ................................................................................................................. [0 ACLs]
  o- luns .................................................................................................................. [1 LUN]
    o- lun0 ........................................................................................ [iblock/linx_disk1 (/dev/sda6)]

10、创建acls

/qla2xxx/50:0...0:03:af:dd:d8> acls/ create 50:01:43:80:01:34:9a:8c
Created Node ACL for 50:01:43:80:01:34:9a:8c
Created mapped LUN 0.
/qla2xxx/50:0...0:03:af:dd:d8> ls
o- 50:01:43:80:03:af:dd:d8 ............................................................................................... [enabled]
  o- acls ................................................................................................................. [2 ACLs]
  | o- 50:01:43:80:01:34:9a:8c ...................................................................................... [1 Mapped LUN]
  |   o- mapped_lun0 ................................................................................................... [lun0 (rw)]
  o- luns .................................................................................................................. [1 LUN]
    o- lun0 ........................................................................................ [iblock/linx_disk1 (/dev/sda6)]

11、保存配置

保存完配置后，需重启服务器生效。

/qla2xxx/50:0...0:03:af:dd:d8> saveconfig 
Save configuration? [Y/n]: y
Performing backup of startup configuration: /var/target/backup-2017-06-08_14:08:36.lio

12、保存配置时可能出现的报错

报错信息

/qla2xxx/50:0...0:03:af:dd:d8> saveconfig

    % (val_type, value))
ConfigError: Unknown value type 'qla2xxx_wwn' when validating 50:01:43:80:03:af:dd:d8

解决方法

vi /usr/share/pyshared/rtslib/config.py
347         elif val_type == 'naa':
348             if is_valid_wwn('naa', value):
349                 valid_value = value
+350         elif val_type == 'qla2xxx_wwn':
+351             if is_valid_wwn('qla2xxx_wwn', value):
+352                 valid_value = value

vi /usr/share/pyshared/rtslib/utils.py
559     elif wwn_type == 'unit_serial' \
560             and re.match(
561                 "[0-9A-Fa-f]{8}(-[0-9A-Fa-f]{4}){3}-[0-9A-Fa-f]{12}$", wwn):
562         return True
+563     elif wwn_type == 'qla2xxx_wwn' \
+564             and re.match(
+565                 "[0-9A-Fa-f]{2}(:[0-9A-Fa-f]{2}){7}$", wwn):
+566         return True

13、配置完存储后，在HA-1和HA-2上重新加载模块

rmmod qla2xxx
modprobe qla2xxx

14、重新存储服务器

配置完存储或者修改了存储的配置后，需要重启存储服务器。

root@rocky:~# reboot

15、查看路径

在HA-1和HA-2上安装完多路径后，可以使用下面的命令查看路径

multipath ll   #查看路径
multipath -v3   #重新加载路径信息
multipath -F   #清除路径信息

二、登录交换机

1、安装串口工具

apt-get install minicom

2、minicom使用方法

1、sudo minicom

2、ctrl+a,然后按z键，在弹出的页面按o键

3、配置串口设备：/dev/ttyUSB0

4、配置波特率：115200

5、设置保存为dfl

3、交换机设置ip地址

FCSW1:admin> ipaddrset
Ethernet IP Address [172.16.0.120]:172.16.0.120
Ethernet Subnetmask [255.255.255.0]:255.255.255.0
Gateway IP Address [172.16.0.254]:172.16.0.254
DHCP [Off]:

4、查看交换机ip地址

ipaddrshow

5、交换机账号密码

交换机默认账户；admin，密码：passwrod

三、配置交换机

1、choose switchState: Offline (Persistent) to online

switchcfgpersistentenable

2、查看交换机的配置

switchshow

3、查看zone情况

zoneshow

4、创建zone

zonecreate "zone名称"，“zone成员1；zone成员2”(其中zone成员可以使用端口号（格式：domain id,port id）、wwn和wwn别名。）

zonecreate "zone0","21:00:00:1b:32:90:ee:66;50:01:43:80:03:af:dd:da;50:01:43:80:03:af:dd:d8"

5、创建cfg

执行cfgcreate命令创建新分区配置，分区配置是zone的集合，一个分区配置可以包含一个或多个zone。命令格式为cfgcreate “分区配置名称”,“zone名称1; zone名称2,…”

cfgcreate "cfgzone","zone0"

6、使能分区配置

执行cfgenable命令使能分区配置。命令格式为cfgenable 分区配置名称

cfgenable cfgzone

7、保存分区配置

cfgsave

8、查看配置后的显示情况

FCSW1:admin> zoneshow

Effective configuration:
 cfg:	cfgzone	
 zone:	zone0	21:00:00:1b:32:90:ee:66
		50:01:43:80:03:af:dd:da
		50:01:43:80:03:af:dd:d8

9、向分区中添加新成员

命令格式为zoneadd “分区名称”, “新成员1; 新成员2; …”

zoneadd "zone0","50:01:43:80:03:af:dd:da"
cfgsave

10、向分区配置中添加新成员

命令格式为cfgadd “分区配置名称”, “zone名称1; zone名称2; …”

cfgadd "cfgnew","zone2;zone3"
cfgsave
