1. Environmental description:
Ø Storage 5600V3 , ip192.168.0.5
ØVirtualization platform FusionSphere
Ø One IP of CentOS6.5 virtual machine: 172.28.13.22
ØHuawei multi-path software installation package
2. Network topology:
Application environment structure
3. Storage configuration process
Configure Ethernet module IP--> create storage pool --> create lun--> create lun group --> create host --> create host group --> create mapping view
3.1. Log in to the 5600V3 console and configure the corresponding module IP
3.2. Create a storage pool
Use raid1 for temporary testing
3.3. Create luns
Create two luns
3.4. Create a lun group
Add the newly added luns to the selected luns
3.5. Create a host
You don't need to fill in the IP address, and the host server actively initiates the connection
3.6. Create a host group
3.7. Create a map view
Add the previously created lun group and host group to the mapping view
4. Server configuration
4.1. Install multipath software
Upload multipath packages to the server
option 1 ( boot from local )
then restart the server
4.2. Server initiated
[root@test network-scripts]# iscsiadm -m discovery -t sendtargets -p 192.168.10.4
192.168.10.4:3260,1549 iqn.2006-08.com.huawei: oceanstor: 2100c81fbe228b28 :: 1020602: 192.168.10.4
[root@test network-scripts]# /etc/init.d/iscsid start
set profile
[root@test ~]# vim /etc/iscsid.conf
node.startup=automatic
node.session.timeo.replacement_timeout=1
Add an initiator to the stored host configuration
4.3. Start nxup service
Start the nxup service to make UltraPath take effect. When the nxup service is started , it will prompt whether to process the existing UltraPath that can be taken over. These disks must be removed before the service can start successfully. Before deleting a disk, make sure that there is no current business, including volume management software, clusters, and file systems that can be taken over by UltraPath . The operation steps are as follows: Execute service nxup start or /etc/init.d/nxup start .
[root@test ~]# /etc/init.d/nxup start
Discover the storage and see the two luns we created on the storage earlier
[root@test ~]# fdisk -l
5. Virtual machine IPsan lun expansion
5.1. Create a storage pool
Suppose you need to add 200G capacity
5.2. Create luns
5.3. Create a lun group
5.4. Create a map view
Select the lun group you just created
Select HostGroup-test host group
Click OK
5.5. Hot expansion on the host
[root@test ~]# hot_add
Begin to delete LUNs whose mappings do not exist
Begin to delete LUNs whose mappings are changed.
begin scan host0
begin scan host1
begin scan host4
The device scanning is complete.
Check the disk and see the newly created 200G lun
[root@test ~]# fdisk -l
