Mapping a Volume to a Host To enable a data host to access a volume you created, you must map the volume to the host. The port World Wide Name (WWN) of each host 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 port WWN 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 Add or Modify a Mapping panel: a. Select the host WWN value that you identified before beginning. b. Type the LUN. c. Leave the access type set as read-write. d. Select all ports. e. Click Map It. The host has read-write access to the volume through any controller host port. 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. Create a file system on the volume. 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. 50 HP StorageWorks 2012sa Modular Smart Array user guide • May 2008

Mapping a Volume to a Host
To enable a data host to access a volume you created, you must map the volume to
the host. The port World Wide Name (WWN) of each host 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 port
WWN 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 Add or Modify a Mapping panel:
a.
Select the host WWN value that you identified before beginning.
b. Type the LUN.
c.
Leave the access type set as read-write.
d. Select all ports.
e.
Click Map It.
The host has read-write access to the volume through any controller host port.
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.
Create a file system on the volume.
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.
