Deployment Guide

Configure a Linux host with iSCSI network adapters
The following sections describe how to configure a Linux host with iSCSI network adapters:
● Complete the PowerVault Manager guided system and storage setup process.
● Refer to the cabling diagrams within this guide before attaching a host to the storage system; careful planning ensures a
successful deployment.
● Administrative or privileged user permissions are required to make system-level changes. The following sections assume root
level access and that all required software packages are already installed, for example, iSCSI-initiator and DM Multipath.
●
Complete a planning worksheet with the iSCSI network IP addresses to be used, per the example in the following table.

The following instructions document IPv4 configurations with a dual switch subnet for network redundancy and failover. It does
not cover IPv6 configuration.
Attach a Linux host with iSCSI network adapters to the storage system
1. Ensure that all network adapters have the latest supported firmware and drivers as described on the Dell Support portal.
2. Use the iSCSI cabling diagrams to cable the host servers to the switches or directly to the storage system.
Assign IP addresses for each network adapter connecting to the iSCSI
network
CAUTION:
The IP addresses must match the subnets for each network, so ensure that you correctly assign IP
addresses to the network adapters. Assigning IP addresses to the wrong ports can cause connectivity issues.
