Configuration: Device Mapper Multipath for Linux

Using or modifying any nodes other than the multipathing device nodes can 

result in array or file system problems, including loss of communication with the 

array and corruption of the file system. Avoid accessing any device other than the 

multipathing device. 

After creating a partition on a multipathing device, all IO operations, 

including filesystem creation, raw I/O and file system I/O, must be done through the 

partition node, not the multipathing device nodes. 

The following tasks must be completed before proceeding. For more 

information about steps 1 and 2, see the MD3200 and MD3220 storage arrays 

Deployment Guide. For more information about step 3, see "Creating Virtual 

1 Install the host software from MD3200 Series resource media—Insert the 

resource media to start the installation of Modular Disk Storage Manager 

(MDSM).

Red Hat install of 5.x needs a remount of the DVD media to make 

contents executable.

2 Reboot when prompted by the install program—The installation program 

prompts for and needs a reboot at completion of install.

3 Create and map virtual disks using MDSM—After configuring the arrays 

using the Modular Disk Configuration Utility (MDCU), run the MDSM 

to create and map virtual disks.

Using the MDSM software:

1 Map the host server to the MD3200 Series storage array
2 Create the Virtual Disks
3 Map newly created arrays to your host server

Any array configured with MDCU automatically adds to the list of 

Devices in the PowerVault Modular Disk Storage Manager Enterprise 

Management Window (EMW).
