I'm setting up some iSCSI storage (Lenovo) along with 3 physical servers running RHEL7.
Each server has 2 NICs for the main network (bonded) and 2 NICs for the iSCSI network. The Lenovo storage has 4 ports connected to 2 physical switches. The iSCSI NICs in each server go to 1 port in each of the switches."
I'm using puppet to configure the iSCSI NICs and was wondering if I should create a bond for the connection to the storage? Currently they're 2 separate NICs and the storage only reports seeing a single "host port" per server (I was maybe expecting to see two host ports per server?). The storage describes the host port with the iscsi initiator name (as found in /etc/iscsi/initiatorname.iscsi)
Alternatively is there a way you can get the iscsi service to go out on the 2nd NIC, so it registers a second host port with the storage? Or am I worrying unnecessarily?
Thanks,
Rob.
