5. Begin using the file system as any other directory to host applications or file services.
6. Repeat steps 1–5 for each provisioned volume in the ME Storage Manager. For example, to
/dev/mapper/mpathb
, correlating to
sg block devices /dev/sdc
and
/dev/sde
.
iSCSI host server configuration for Linux
The following sections describe how to configure iSCSI host servers running Linux:
Prerequisites
•
Complete the ME Storage 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 hosts 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.
