HP StorageWorks MSL4048 Tape Library getting started guide (AH560-96001, March 2007)

• The Library has an LVDS SCSI bus. It is NOT
compatible with a standard differential (Diff) or High-
Voltage (HVD) SCSI bus.
• The default SCSI ID for all full-height tape drives is 4.
• The default SCSI ID for half-height drives is 4 or 5,
depending on the drive bay as shown below.
You must provide a Fibre Channel cable for each tape
drive in the Library. Each Fibre Channel tape drive has
two Fibre Channel ports. Only one port may be used at
a time, but both ports can be connected for path
failover if your application supports path failover.
Direct connection
You will need a 2 Gb or 4 Gb Fibre Channel HBA.
SAN connection
All switches between the host and the Library must be of
the appropriate type. A 2 Gb switch in the path may
result in performance degradation when backing up
highly compressible data to a 4 Gb tape drive.
Configure zoning on the fibre switch so only the backup
servers can access the Library.
Planning the Fiber Channel
configuration: Fibre Channel
8b
The server must have a SAS HBA with an external
connector. Most SAS RAID controllers do not support
multiple LUNs, which are needed to communicate with
the Library robotic.
Planning the SAS
configuration: SAS

Changing the SCSI ID
9
If you need to change the SCSI ID for any of the tape
drives, do so before connecting the Library to the host
computer.
1. Attach the power cord to the Library.
2. Power on the Library from the front panel.
3. Check the LCD screen to make sure the Library is
receiving power.
4. Use the control keys below the LCD screen to
highlight Configuration > Drives > Drive #, where #
is the number of the drive whose SCSI ID you need
to change. Press the OK key.
5. Press OK to select the editable block. Use the Up
and Down control keys to change the SCSI ID. Press
OK to select the value.
6. Highlight Save and press OK to save the SCSI ID.
Power off the Library.
WARNING! Do not connect the Library to a SAS
RAID controller unless the EBS compatibility
matrix shows that the controller is qualified with
the Library. The server might not be able to boot
when the Library is connected to a non-
supported SAS RAID controller. Check the EBS
matrix at http://www.hp.com/go/ebs to find a
SAS HBA that is supported on your server and
qualified with the Library.
