HP StoreEver MSL8048 and MSL8096 Tape Libraries Getting Started (AK382-96027, December 2012)

8c Planning the FC configuration
On tape drives with two FC ports, HP recommends
that only one port be connected unless your application
supports path failover or you have configured library
managed path failover.
Direct connection
You will need a 4 Gb or 8 Gb FC HBA. A 4 Gb HBA
is recommended for LTO-4 tape drives for optimum
performance. An 8 Gb HBA is recommended for LTO-5
and LTO-6 tape drives for optimum performance.
SAN connection
All switches between the host and the library must be
of the appropriate type. For example, 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.
You must provide a Fibre Channel cable for each tape
drive. The maximum cable length (in meters) is based
on the tape drive and external cable type, as shown:
8 Gb4 Gb2 Gb

NOTE: For additional FC configuration
information, see “11b Connecting the library:
Fibre Channel” (page 9). See the user and
service guide for instructions on changing the
FC configuration.
9 Changing the SCSI ID
In a parallel SCSI library, 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 a power cord to the library and a power
outlet.
2. Power on the library by pressing the power button
on the front panel.
3. Use the control keys below the LCD screen to
highlight Configuration > Drives > Drive #, where
# is the number of the tape drive with the SCSI
ID that needs to change. Press the OK key.
4. Press OK to select the highlighted block. Use the
Up and Down control keys to change the SCSI
ID. Press OK to select the value.
5. Highlight Save and press OK to save the SCSI ID.
6. Change the SCSI ID of other tape drives if
necessary.
TIP: The SCSI ID can also be changed from
the RMI Configure: Drive screen once the RMI
is configured.
10 Preparing the host
If necessary, install software, a host bus adapter (HBA),
and compatible drivers in the host computer.
For parallel SCSI and SAS libraries, ensure that your
HBA supports multiple LUNs. For parallel SCSI devices,
verify that multiple LUN support is enabled for the HBA
and operating system.
Verify that your HBA is supported on your host
computer and qualified with the library with the EBS
matrix available at:
http://www.hp.com/go/ebs
Install the HP Library & Tape Tools diagnostic utility to
see what devices are connected to the host, verify the
installation, upgrade firmware, and to aid in
troubleshooting. Download L&TT without charge from:
http://www.hp.com/support/TapeTools
HP recommends that the host server be powered off
before attaching new devices.
