1. Select the device in the list to display its details and then click on Edit. 2. Amend details as appropriate and click Update to apply them. To delete a library (administrators only) Select the required device and then click on Delete in the Details section to delete it. You will be prompted to confirm that this is what you wish to do. WARNING! All data on the device will be deleted. The library's deduplication store is also deleted. It may take some time to delete all the files and free space on the HP StoreOnce Backup system. Emulation types for tape devices HP StoreOnce Backup systems emulate a range of physical tape devices, which are listed below. Table 6 Emulation types for tape devices Emulation type Description D2DBS Generic Library: If it is supported by your backup application, this is the preferred emulation type because it does not emulate any physical library types in existence and is, therefore, clearly identifiable as a StoreOnce device. It is the most flexible emulation type available; however, backup application support varies by software vendor. If you have selected D2DBS Generic for the Library Emulation Type, you will be able to select Ultrium VT for the drive emulation. This is a generic Ultrium device which is clearly identifiable as virtual. Backup application support for Ultrium VT is reasonable, but not quite as complete as the D2DBS library type, so its not possible to use it with all backup software. NOTE: Symantec prefer their customers to use this emulation type with BackupExec and Netbackup. MSL G3 series (2x24) Library: MSL G3 series (4x48) Library: This is a tape library device with a maximum of two embedded Ultrium tape drives and 24 cartridge slots. It should be used when implementing rotation schemes which involve simultaneous backup jobs to two devices. This emulation type is widely supported by backup applications. This is a tape library device with a maximum of four embedded Ultrium tape drives and 48 cartridge slots. It should be used when implementing rotation schemes which involve simultaneous backup jobs to more than two devices or those that use a large number of cartridges devices. This emulation type is widely supported by backup applications. Libraries page 19
