Configuring Storage 37

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 storage array to be

configured, select the

Configure

tab.

NOTE: In the examples to follow the storage array “sg23_training” is a

PowerVault MD3000i storage array with virtual disks already configured using

the Create Virtual Disks selection. The new system being added to an existing

host group is named Valhalla.

From the

Configure

tab, select

Configure Host Access (Manual)

Enter the host name for the server which has XenServer software installed.

Select

as the host type.

From the next screen, specify the iSCSI initiator by selecting the

New

button. On the

screen enter the XenServer

iSCSI initiator name configured in step 1. The label is auto-populated

with the server name. See Figure 5-3.

Host Group configuration starts from the

Configure Host Access

(Manual) - Specify Host Group

screen. If provisioning storage as

shared storage for a XenServer pool, a host group must be defined so

the MD3000i storage subsystem has a configured iSCSI path to each

of the hosts.
