Use Openfiler to simulate multiple paths of hosts to storage (multiple paths)

Use Openfiler to simulate multiple paths of hosts to storage (multiple paths)

Openfiler has two network adapters, each with an IP address: 192.168.188.170 and 192.168.188.169 respectively.
The idea of simulating multipath is that the host connects to Openfiler through the above two IP addresses,
In this case, if you divide the n LUNs on the Openfiler, and the n LUNs are mapped to the host, the fdisk-l on the host side will see the LUNs on the 2*n storage.

On the Openfiler, the LUN is divided according to the requirement and mapped to rhel5.8x64bit, the operation on Openfiler is the same as that of a single NIC.
The difference lies in the operation of the host side (Rhel5.8x64bit):

Iscsiadm-m discovery-t st-p 192.168.188.170 iscsiadm-m node-t iqn.1994-05.com.redhat:f2d202fa465-p 192.168.188.1
70-l

At this point, the execution result of Fdisk-l is the LUN on n storage

The following operation is more than a single NIC: That is, more than one host to the storage link

Iscsiadm-m discovery-t st-p 192.168.188.169 iscsiadm-m node-t iqn.1994-05.com.redhat:f2d202fa465-p 192.168.188.1
69-l

At this point, Fdisk-l's execution result is a LUN on the 2*n storage
