When a user performs an upgrade of a unit with the initial RTS Firmware (0.80 FW), the librarywill show now a service tag field in the RMU (Remote Management Interface). The value in thefield will not correspond to your unit actual service tag. The value in the service tag field will read“ABC1234”. The service tag information is added during the manufacturing process. Your servicetag is not changed; you can find the service tag in the front of the unit.PowerVault TL4000 has a reserved slot “DCS” (designated cleaning slot)Initial 0.80 Firmware for the TL4000 has a reserved cleaning slot. Firmware 3.90 added a featurethat allows the user to reconfigure the cleaning slot and the I/O slots into storage. A firmwareupdate will leave the library slot configuration settings intact.

This statement is incorrect. Running the slot toslot diagnostics test will result on lost media inventory information. User must re-inventory thelibrary after a slot to slot diagnostics test is executedTL2000/TL4000 Reports Wrong unit configuration during bootThe TL4000/TL2000 reports unit configuration status during its boot process. The configurationreported in some instances does not match the actual library configuration i.e. “number of drives”,“state of the I/O slot”. The issue is due to the library reporting the status prior to fully configure thedevices. Once the library initialization is complete the library configuration will be correct. Pleaseignore the booting process messages until the unit has completed its initializing cycleTL2000/TL4000 Drive power configuration changes (make to more than a single drive) donot take effect when half height drives are installed in the unit
