hi,
Can anyone please explain me the behavior of UCSM vNIC/vHBA placement policy, and its three options assigned-only, Exclude-Dynamic and Exclude-Unassigned. I have gone through the documentation, but I am not very clear yet.
May be an explaining with an example will help.
Sample scenario.
Full blade having Palo on left side, and Menlo Emulex on right side, with 8 VNICs (4 dynamic, and 4 manual), with each of the three options.
thanks

Tejo, there are two reasons that you would want to use a placement policy.
Other than those two reasons I don't know when you would use a placement policy unless you just wanted to make sure the OS sees the vNICs/vHBAs on specific PCI slots.
The exclude-dynamic comes into play with the Dyamic vNIC Connection Policies I mentioned in option 2 above. Exclude-unassigned would be where you have some that you want to assign (vNICs) but you don not care about where the vHBAs get assigned.
I personally have only had the need to use them in the 2 scenarios above.
With your specific scenario you would use the placement policy to assign some vNICs/vHBAs to the Emulex card (2 max for vNIC and vHBAs) and some to the Palo (dynamic vNIC connection policy or more than 2 vNICs. Or you might want all of your vHBAs to use the Emulex and all of your vNICs to use the Palo.
