Server configuration
27 Dell EMC SC Series with Red Hat Enterprise Linux 7x | CML1071
In this demonstration, only the em2 interface is configured to the iSCSI VLAN as shown in the following
ifconfig and netstat output. In production use, it is recommended to configure more than one iSCSI interface
for each Linux host, using dm-multipath for path, redundancy, and I/O queue management.
1. Configure the network interface.
# ifconfig -a

em2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

2. With the em2 interface configured, and knowing that the SC Series discovery IP addresses are
10.10.97.2 and 10.10.130.2, accordingly (as identified from the SC Series management GUI),
validate that these IP addresses can be pinged.
