I'm looking for a simple answer but not able to find it anywhere so here it goes:
The environment we are talking about has a FAS 32xx and 2 Esxi 5.0 servers. The Esxi servers have 4 physical NICs each (2 for Networking, 2 for iscsi)
I Created 2 separate VSwitches on the esxi servers. one of those Vswitches is used for ISCSI. In this vswitch there are 2 VMkernel port groups configured. Both have an IP address and both are connected to a different Physical NIC. I Also created a Virtual Machine VMkernel for snapdrive (here is it going wrong I fear.)
The Client system is a Windows 2008 R2 server and its C: drive is on a virtual disk on a LUN on the Netapp. It has also Snapdrive installed to connect to an other LUN on the Netapp, lets call it the D: drive. For this connection is an extra Virtual Network configured to connect to the NetApp DIRECTLY from the Guest Windows system. (also not correct I think?)
Now my question/issue:
When I pull out one of the UTP cables used for iscsi in ESXi, it fail-overs nicely to the other NIC and the guest system is still up and running (as it should). But at this moment the snapdrive installation loses its connectivity to the NetApp, so it doesnt failover. :s
Can somebody explain to me what would be the best practice to follow in my environment? Because, after everything i have read over the past few weeks, my only conclusion is that the current configuration is wrong. But what is the right one? (And I mean the configuration in Esxi (Networking)).
