When creating dual port virtual devices, the LUN numbering on both ports follows the conventions for
default LUN numbering (see Default LUN numbering ); however, if you use LUN mapping for a dual port
device (see LUN mapping ), the de fi ned LUN number for that device for a speci fi ed host applies to both
device paths. Follow the operating system LUN requirements (see Operating system LUN requirements
and restrictions ) when con fi guring the paths.
Creating a virtual library
Before creating a virtual library, you must fi rst:
• Determine the best way to manage VLS virtual library and tape drive LUNs for your environment
(see Managing virtual device LUNs
)
• Determine the best way to con fi gure virtual libraries and tape drives on your VLS for your
environment. See the HP StorageWorks 300 Virtual Library System solutions guide .
You can con fi gure any combination of virtual tape libraries and virtual tape drives up to the maximum
number supported on the VLS. You can con fi gure 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:
1. Open a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL .
2. Click the System tab.
3. Select Chassis in the navigation tree.
4. Click Create Virtual Library in the task bar.
The Create Virtual Library Wizard opens ( Figure 37 ).
Figure 37 Create Virtual Library Wizard window (1 of 12)
5. Select the FC host port and node on which to present the virtual library.
Only one port or port pair may be selected.
6. Select the type of tape library to emulate.
