Setup Guide
Configuring Storage 29
By default, the physical network interface on which the XenServer management
interface is configured is chosen to route the IP storage traffic. However,
a physical interface or a bond of multiple interfaces can be configured to
segregate storage traffic from management traffic.
NOTE: For specific steps on using MD3000i and MD32x0i with an iSCSI initiator
running inside a virtual machine, see the MD3000i Installation Guide or the MD32x0i
Owners Manual at support.dell.com/manuals.
Creating a Storage Repository on PowerVault MD3000i and MD32x0i
Storage Arrays
1
Change the iSCSI IQN of the XenServer host to a string of your choice by
selecting the host in Citrix XenCenter, viewing its
General
tab, and
clicking the
Edit
button.
The
Edit General Settings
dialog box is displayed, where you can modify
the iSCSI IQN string.
2
Using the MDSM interface, create virtual disks on the PowerVault
MD3000 and MD32
x
0i storage enclosure using the steps described in
Dell
PowerVault Modular Disk Storage Manager User’s Guide
at
support.dell.com/manuals
. Ensure that the XenServer hosts have a
physical path to the controller which owns the newly created virtual disk.
3
From the
Mappings
tab in the
Storage Array Profile
window, note the
controller number which owns the newly-created volume. If you wish to
provide the XenServer hosts access to more than one volume, ensure all
the volumes are on the same PowerVault MD3000i and MD32
x
0i
controller.
To change the controller that owns a volume, in the MDSM interface:
a
Go to
Modify
Change Virtual Disk Ownership/Preferred Path
.
b
Select the appropriate disk group and the virtual disk.
c
Select RAID Controller Module 0 or 1 as the virtual disk owner and
click
Change
.
4
Run the Modular Disk Storage Manager and manually add the XenServer
host(s) based on the new iSCSI IQN entered in step 1. After opening the
MDSM and selecting the PowerVault MD3000i and MD32
x
0i storage array
to be configured, select the
Configure
tab.
