Chapter 4 Configuring a System for the First Time 59
Mapping a Data Host to a Volume
To enable a data host to access a volume you created, you must map the volume to
the host. The host value, typically the IQN (iSCSI qualified name), of each host port
connected to the system is automatically added to the system’s global host port list.
Before mapping a data host to a volume you must identify the data host’s iSCSI
node name (IQN) and a LUN that the host is not using.
To map a data host to a volume:
1. Select Manage > Volume Management > Volume Mapping > Map Hosts To Volume.
Notice that your first virtual disk and its volume are selected, and the volume’s host
mapping values are set to None.
2. In the Assign Host Access Privileges panel:
a. Select the host port IQN value that you identified before beginning.
b. Type the LUN that you identified.
Notice that the mapped host will have read-write access through all controller
host ports.
c. Click Map It.
Testing the Configuration
To determine that your system is ready for use, test the configuration as follows:
1. In SMU, select Monitor > Vdisk Status and view the configuration information for
each virtual disk.
The virtual disk status is Critical during initialization but you can perform I/O to the
volume.
2. From the data host:
a. Make the volume an operating system partition.
b. Verify that you can access the mapped volume and the volume size shown on the
data host matches the size shown in SMU.
c. Verify that you can write data to the volume.
If the above tests succeed, your system is ready for use.
