Using the MDSM software:

1Map the host server to the MD3600i Series storage array.

2Create the Virtual Disks.

3Map newly created arrays to your host server.

NOTE: Any arrays configured with MDCU automatically get added to the list of Devices in the PowerVault Modular Disk Storage Manager Enterprise Management Window (EMW).

Device Mapper Configuration Steps

To complete the DM multipathing configuration and make storage available to the Linux host server:

1Scan for virtual disks. See "Scan for Newly Added Virtual Disks" on page 188.

2Display the multipath device topology. See "Display the Multipath Device Topology Using the Multipath Command" on page 188.

3Create a partition on a multipath device node. See "Create a New fdisk Partition on a Multipath Device Node" on page 189.

4Add a partition to DM. See "Add a New Partition to Device Mapper" on page 190.

5Create a file system on a DM partition. See "Create a File System on a Device Mapper Partition" on page 191.

6Mount a DM partition. See "Mount a Device Mapper Partition" on page 191.

The following instructions show how to complete each of these steps.

In the following command descriptions <x> is used to indicate where a substitution should be made. On Red Hat Enterprise Linux systems <x> is the number assigned to the device. On SUSE Linux Enterprise Server systems <x> is the letter(s) assigned to the device.
