I have a physical box that is directly connected to the iSCSI network. It has 2 iSCSI NICs. My Nimble has 5 iSCSI +1 Management.
Inside NCM when I connect a new volume, it only connects 8. It seems like there is one on the array side that isn't happy, but I don't have any alerts or other indications to a problem.
My VMware hosts connect and show 10 connections (Each ESXi host has 2 iSCSI connections back to the iSCSI network)
I have another physical box that has 4 iSCSI NICs. The volumes that have been connected for a long time show 20 connections, but the newest one I just added shows 10.
Switch gear is 2 Dell 6024 (not stacked). 4 port port-channel between the 2. All interfaces in the port-channel are up on both switches so I don't suspect issues there.
Where can I investigate this further? Any ideas?
