How to Configure Software iSCSI including Multipath

AllanHoggJan 13 2015 — edited Jan 15 2015

Oracle Linux 6.6 3.8.13-44.1.1.el6uek.x86_64

Installed with a production network interface card and two 10G network connections for iSCSI traffic only. Both iSCSI cards are on the same vLAN with different IP addresses on a range.

Connecting to a DELL Compellent SAN with 1TB of storage presented to the machine.

Connections can be successfully made via iSCSI and the target can be logged into however in the disk utility window on the server the storage shows as a single 1.1TB multipath drive as dm-0 along with 4 separate connections between sdc and sdf.

The output from multipath -ll is as follows.

I'm guessing that something in the underlying configuration is incorrect and would appreciate any assistance that can be provided.
