FreeNAS 8 ISCSI MPIO SATP suggestion

[makruger]

Hello,

I have 2 FreeNAS 8.03 ISCSI targets configured in ESXi5 to use MPIO round robin (VMW_PSP_RR). Apparently however, my storage array type is not defined by any of the policies...which is probably why I am seeing the warning/error shown below. Given this storage stuff is all a bit new to me, can anyone suggest an appropriate SATP for FreeNas 8.03?

Thanks,

MK

After doing some more reading on this subject, it just occured to me that I really did not provide enough information. So I should also mention my configuration does not involve any kind of clustered or "High Availability" storage array. This I believe would rule out Active/Active or Active/Passive....as there is only 1 active array containing 2 unique targets. Nothing is clustered, and nothing is failing over. Both targets are always active....as are all 4 path connections in ESXI (Each showing as active I/O). I guess that might explain the following as well....
