can two ports in a LACP group be connected to two Nexus switches?

I plan to create a LACP group which is consisits 2 x 10Gbit on NetApp storage. To ensure redundancy, can I connection two ports in the same group to two different Nexus 5545 switches?  I heard I can not split two ports in the same group.

Thanks for your advice!

No license required and the vpc configuration is a quite simple.

Be aware when you create a vpc domain, the recommendation is that all devices attached should be dual-attached with port-channels.

Yes, this is possible if the two 5Ks are configured for VPC and the channel-group is VPC-enabled.

Thanks for your message.

Is vPC usually enabled or disabled in normal circumstance? what impact on the switch if I wanted to enable it? The reason I am asking these questions is because our networking guys told me that two ports in LACP could not be connected to two different NX switches. So, I am wondering what difficulties are to stop them to do so, or if too much work to do then it is not worth to do so, are there any addtional licesnes requred.

Thanks for your further advices!
