14 Dell EMC SC Series: Red Hat Enterprise Linux Best Practices | CML1031
6. In the following example, the iSCSI ports on the SC Series storage system have the IP addresses
172.16.26.180 and 10.10.140.180, respectively.
a. Configure the first path:
# iscsiadm -m discovery -t sendtargets -p 172.16.26.180
172.16.26.180:3260,0 iqn.2002-03.com.compellent:5000d3100000677c
172.16.26.180:3260,0 iqn.2002-03.com.compellent:5000d3100000677e
172.16.26.180:3260,0 iqn.2002-03.com.compellent:5000d31000006780
172.16.26.180:3260,0 iqn.2002-03.com.compellent:5000d31000006782
b. Configure the second path:
# iscsiadm -m discovery -t sendtargets -p 10.10.140.180
10.10.140.180:3260,0 iqn.2002-03.com.compellent:5000d3100000677d
10.10.140.180:3260,0 iqn.2002-03.com.compellent:5000d3100000677f
10.10.140.180:3260,0 iqn.2002-03.com.compellent:5000d31000006781
10.10.140.180:3260,0 iqn.2002-03.com.compellent:5000d31000006783
7. Log in to the target ports. The iSCSI daemon will save the nodes in /var/lib/iscsi and automatically
log into them when the daemon starts. Use the following commands to instruct the software to log into
all known nodes.
# iscsiadm -m node --login
Logging in to [iface: default, target: iqn.2002-
03.com.compellent:5000d31000006782, portal: 172.16.26.180,3260] (multiple)
Logging in to [iface: default, target: iqn.2002-
03.com.compellent:5000d31000006783, portal: 10.10.140.180,3260] (multiple)

8. Launch the DSM GUI and create a server object on the SC Series storage system.
9. Create and map the SC Series volumes to the server.
10. On the Linux system, rescan the HBAs to discover new volumes presented to the system. See
section 3.
As long as the iSCSI daemon automatically starts during boot, the system logs in to the SC Series iSCSI
targets and discovers the iSCSI-based volumes.
2.4.3 Scanning for new volumes
The process for scanning the iSCSI software initiator for new volumes is identical to that used for scanning
the Fibre Channel hostX devices as discussed in section 3.1.
