Mounting Storage LUN into Solaris ZFS Storage Pool and Dataset

Hey, It's a simply way to mount your external disks (storage LUN) to your solaris box using ZFS. For example we have one LUN from storage box. The storage communicates to server over FC connection that sanswitch is at there. Bellow the simply diagram :

|storage box|-------------|sanswitch|--------------|solaris box|

In server, should be check wwn number. This number is used by sanswitch to construct zone configuration. In solarisbox we can use 'fcinfo' command to check wwn on FC card which state is online. In sanswitch check the port status, is it online or not?

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.
