8. Enter the number of cartridges and the cartridge size in the appropriate boxes (Figure 76). The default number of cartridges is based on the maximum number of slots configured for the virtual library. The default cartridge size is based on the actual size of the type of cartridge emulated. The system calculates and displays the amount of required storage. If the required storage exceeds what is available, the overage appears in red. You can allow the oversubscription of storage capacity (see "Enabling and Disabling Oversubscription" on page 149), or you can change either the number of cartridges or the cartridge size (or both) to correct the overage condition. Figure 76 Create Virtual Library Wizard window (10 of 12) . 9. Click Next Step. A summary window opens and displays details about the cartridges you created. 10. Click Next. 11. Click Return. The System tab window opens. You can now select the new library, tape drives, and cartridges in the navigation tree to view their configuration information, such as their default LUN numbers. Destroying a Virtual Library NOTE: Destroying a virtual library may create a gap in the default LUN numbering on the Fibre Channel host port to which it was mapped. If a gap is created, restart the VLS device emulations to remove the gap. See "Restarting VLS Device Emulations" on page 175. Most operating systems will ignore (cannot access) any virtual devices with LUN numbers that follow a gap in the LUN numbering on an Fibre Channel host port. NOTE: You cannot destroy a library that is currently being accessed by a backup application. 168 Configuration
