1．Do not connect an Ultrium 960 device to an SE SCSI bus, as it severely degrades performance.
2．The HP StorageWorks MSL2024 tape library is NOT compatible with a standard differential (Diff) or High-Voltage Differential (HVD) SCSI bus. This library is compatible with a narrow (50-pin) SCSI bus using a 68-pin to 50-pin adapter that terminates the unused 18 pins (not included with the library). These adapters are sometimes labeled as high-byte termination.
3．Use a SCSI-3 LVDS host bus adapter with the HP StorageWorks MSL2024 tape library. To ensure optimum performance, HP recommends an Ultra320 HBA for the Ultrium 960 tape library and Ultra160 or higher HBA for the Ultrium 448 tape library.
A single-ended SCSI host bus adapter severely degrades performance and limits cable length. Also, if
there are any SE devices on the same SCSI bus, the entire SCSI bus negotiates down to SE speed,severely degrading performance.
4．The HP StorageWorks MSL2024 tape library uses a single SCSI ID and dual LUNs to control the tape
drive (LUN 0) and library robotic (LUN 1). The library requires an HBA that supports LUN scanning. If it is
not enabled, your host system scan beyond LUN 0 fails to discover the library. It just sees the tape drive.
Some HBAs, such as RAID controllers, do not support LUN scanning. Refer to the EBS matrix at
http://www.hp.com/go/ebs for the most up-to-date SCSI HBA compatibility information.
5．Ensure the library is properly terminated. If the library is the only SCSI device, other than the SCSI host
adapter on the selected SCSI bus, it must be terminated. Likewise, if the library is physically the last
SCSI device on the SCSI bus, it must be terminated. Only the devices physically located at the be end of the SCSI bus should be terminated.
6．The HP Ultrium 960 tape drive is an Ultra320 SCSI LVD device. Use only cables and terminators
ified for Ultra320 or labeled as MultiMode.
he HP Ultrium 448 tape drive is an Ultra160 SCSI LVD/SE device. Use only cables and terminators
ified for Ultra160 or labeled as MultiMode.
7．To disconnect all power from the library, remove the power cord from the outlet. The power
button only puts the power on stand-by.
8．Do not place data cartridges near sources of electromagnetic energy or strong magnetic fields such as
computer monitors, electric motors, speakers, or X-ray equipment. Exposure to electromagnetic energy
or magnetic fields can destroy data and the embedded servo code written on the media by the cartrie manufacturer, which can render the cartri e unusable.
9．The mailslot in the left magazine is used only with host system software that supports this feature. The mailslot feature allows you to insert or remove a single tape without removing the entire magazine. The benefit of using a mailslot is that the library will not inventory the magazine again, allowing the library to continue to function normally.
10．Reserved slots are slots that can be accessed by the remote management interface (RMI) and the operator control panel (OCP), but are invisible to the host and backup software.
11．If you change the SCSI ID, you must also cycle power on the host server and reconfigure your
backup software before you can use the library.
12．Random mode is used when there is a full featured or a robotics aware backup application in use. This is the most common mode of operation.
Sequential mode is used when the backup software is NOT robotics-aware or was designed for
standalone drives only. In Sequential mode, the library automatically loads and unloads tapes from the drive. The operator determines a tape to load by loading the desired tape into the tape drive using the operator control panel.
13．If the cleaning cartridge is not a valid cleaning cartridge, the LCD screen displays Invalid Tape and the cartridge is exported.
14．If you would like to keep a cleaning cartridge in the library, the backup software must manage tape drive cleaning or be configured to bypass the slot containing the cleaning cartridge.
