mapping for a dual port device (see "LUN Mapping (v3.x)" on page 123 or "LUN Mapping (v2.x)" on page 128), the defined LUN number for that device for a specified host applies to both device paths. Follow the operating system LUN requirements (see "Operating System LUN Requirements and Restrictions" on page 121) when configuring the paths. Creating a Virtual Library Before creating a virtual library, you must first: • Determine the best way to manage VLS virtual library and tape drive LUNs for your environment (see "Managing Virtual Device LUNs" on page 120). • Determine the best way to configure virtual libraries and tape drives on your VLS for your environ- ment. See the HP StorageWorks 300 and 12000 Gateway virtual library system solutions guide. You can configure any combination of virtual tape libraries and virtual tape drives up to the maximum number supported on the VLS. You can configure one node with up to 16 libraries with a total of up to 128 tape drives. With multiple nodes, a single library can span across nodes. To create a new virtual library, from Command View VLS: 1. Click the System tab. 2. Select Chassis in the navigation tree. 3. Select Create Virtual Library in the task bar. The Create Virtual Library Wizard opens (Figure 25). Figure 25 Create Virtual Library Wizard window (1 of 12) . 4. Select the Fibre Channel host port and node on which to present the virtual library. Only one port or port pair may be selected. 5. Select the type of tape library to emulate. NOTE: The only library emulation Veritas supports for use with Netbackup is the HP VLS emulation. IBM supports using the HP VLS emulation for TSM version 5.5.1 or higher. The HP VLS emulation is not intended for use with other backup applications. 130 Configuration

Creating a Virtual Library
Before creating a virtual library, you must first:
•
Determine the best way to manage VLS virtual library and tape drive LUNs for your environment
(see
“
Managing Virtual Device LUNs
”
on page 120).
•
Determine the best way to configure virtual libraries and tape drives on your VLS for your environ-
ment. See the
HP StorageWorks 300 and 12000 Gateway virtual library system solutions guide
.
You can configure any combination of virtual tape libraries and virtual tape drives up to the maximum
number supported on the VLS. You can configure one node with up to 16 libraries with a total of up
to 128 tape drives. With multiple nodes, a single library can span across nodes.
To create a new virtual library, from Command View VLS:
1.
Click the
System
tab.
2.
Select
Chassis
in the navigation tree.
3.
Select
Create Virtual Library
in the task bar.
The
Create Virtual Library Wizard
opens (

4.
Select the Fibre Channel host port and node on which to present the virtual library.
Only one port or port pair may be selected.
5.
Select the type of tape library to emulate.
NOTE:
The only library emulation Veritas supports for use with Netbackup is the HP VLS emulation.
