Configure IPMP Interface Solaris 11 in easy steps

To provide a redundancy network connection, solaris11 provide IPMP feature which combine more than one ethernet physical connection in to one logical interface as known as ip network multipathing. IPMP is layer 3 protocol which has feature as failure detection, transparent access failover, and packet load spreading.  

What is benefit when you use a ipmp interface?. There was an unexpected situation on network, like network interface is suddenly unconnected, disabled, failure, etc which impacted to your network connection becomes unavailable. When you face with the situations in one physical/logical interface only, it will drive you to be disconnected from network. 

Simply way to create Multipath MPxIO/STMS for SAN connection on Solaris 11

When we have more than one physical connection from a server to a storage for access a same LUN. We should define a MPxIO for 

the SAN connection. With this refference, we would like to introduce a simply way on how to configure MPxIO for SAN in Solaris 11. If you not configure MPxIO, the LUN will appears duplicated in format output. So, configure MPxIO is must for multipath connection.
