In the scenario above, we have only setup only one (1) discovery IP address mapped to a

single interface on a quad port NIC. To ensure proper failover and redundancy in an

enterprise scenario, it is strongly recommended to establish one or more discovery IP addresses on the

host (OS) side; in accordance with mapping a secondary interface on a alternate NIC via a different

VLAN to the Dell Compellent Storage Center.

Adding LUNs

Having completed the procedures above, you can now add this connection to the Dell Compellent

Storage Center. Open the “Create Server” dialog and uncheck the “Only Show Up Connections” box and

let the screen refresh. The iqn for your server should appear in the dialog box.

If the iqn does not appear this latter dialog box, you will need to add the iqn manually.

Left-click the “Manually Define HBA” button, select the iSCSI radio button in the “Transport

Type” selection box and enter the known iqn into the “WWN or iSCSI Name:” text box, left-Click the

“Continue” button, then continue creating the server object per usual procedures. This procedure

should NOT be needed if using Dell Compellent Storage Center code 5.4.x or newer.

Complete the “Create Server” process, then map LUNs to the host. For purposes of this example, we

have created and mapped two (2) 50GB LUNs to the host. On the host, issue this command.

We see the LUNs presented from the Dell Compellent Storage Center to the host and would now need

to build the necessary devices files to support these LUNs. Issue the command.
