HP StoreEver 1/8 G2 Tape Autoloader Getting Started (AK377-96025, December 2012)

11c Planning the FC configuration
On a tape drive with two FC ports, HP recommends
that only one port be connected unless your application
supports path failover or you have configured
autoloader managed path failover.
Direct connection You will need a 4 Gb or 8 Gb FC
HBA. An 8 Gb HBA is recommended for optimum
performance.
SAN connection All switches between the host and the
autoloader must be of the appropriate type. For
example, a 4 Gb switch in the path may result in
performance degradation when backing up highly
compressible data to an 8 Gb tape drive.
Configure zoning on the Fibre switch so only the
backup servers can access the autoloader.
You must provide a Fibre Channel cable for the 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: Forr additional FC configuration
information, see “18 Configuring the FC port”
(page 10). See the user and service guide for
instructions on changing the FC configuration.
12 Changing the SCSI ID
On a parallel SCSI autoloader, if you need to change
the SCSI ID, do so before connecting the autoloader
to the host computer.
1. Plug the power cable into the autoloader and the
power outlet.
2. Power on the autoloader by pressing the power
button on the front panel.
3. On the front panel, press Enter.
4. Press Next until the display shows
Configuration. Press Enter.
5. Press Next until the display shows Change
Drive SCSI ID. Press Enter.
6. Press Next until the display shows the new SCSI
ID. Press Enter.
13a Connecting a parallel SCSI autoloader
NOTE: A parallel SCSI LTO-4 tape drive
should be the only device on the bus.
Attach one end of the parallel SCSI cable to one of
the connectors on the tape drive. Attach the other end
of the cable to the host bus adapter (HBA) or to the
connector on the previous device on the SCSI bus.
If the autoloader is the last or only device on the SCSI
bus, attach a terminator to the remaining SCSI
connector on the tape drive. Otherwise, attach a SCSI
cable to the next device on the SCSI bus. Make sure
that the last device on the SCSI bus is properly
terminated.
IMPORTANT: For the autoloader and tape
drive to operate correctly, the tape drive must
have a SCSI terminator unless the tape drive is
part of a properly terminated chain. This
includes tape drives without an attached SCSI
cable.
