Connecting The Library: Parallel Scsi; Connecting The Library: Sas; Powering On The Library - HP StorageWorks MSL2024 Getting Started

8b Connecting the Library: parallel SCSI
NOTE:
For optimal performance, a parallel SCSI LTO-3 or LTO-4 tape
drive should be the only device on the bus. A maximum of two
LTO-2 tape drives can be on a single Ultra320 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 HBA or to the
connector on the previous device on the SCSI bus.
If the tape drive 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.
Connect the second tape drive, if applicable.
8c Connecting the Library: SAS
The SAS cable recommended for use with the Library has four mini-SAS
connectors on the tape drive end with a SAS 4x (IB) or mini-SAS
connector on the HBA end, depending on the connector on your HBA.
This cable can be used to connect up to four tape drives to a SAS HBA.
Any of the four connectors can be used for any tape drive.
CAUTION:
Mini-SAS connectors are keyed. Do not force a SAS cable's
mini-SAS connector into the tape drive mini-SAS connector
because it might be keyed differently.
CAUTION:
SAS signal rates require clean connections with a minimum
number of connections between the HBA and the Library. Do
not use adapters or converters between the HBA and the Library.
HP recommends a maximum SAS cable length of six meters.
Attach the HBA end of the cable to the SAS HBA. Attach a connector
to each tape drive.
The unused ends of a fanout cable are single channel and not suitable
for use with most disk arrays. Use the other ends to connect tape drives,
or coil and secure them to the rack to minimize stress on the connectors.
NOTE:
Each of the tape drives uses one channel and the cable
recommended for use with the Library maps each of the four
channels from the HBA to one channel on the drive end. You
can plug any of the four drive connectors into any tape drive.

9 Powering on the Library

To use the web-based management interface, plug one end of the
Ethernet cable into the Ethernet port on the back of the Library. Plug the
other end of the cable into an Ethernet LAN port.
Plug the power cable into the Library from an AC power outlet.
Power on the Library using the power button located on the front panel.
Check the LCD screen to make sure the Library is receiving power.
Power on the host server and all devices you powered off earlier.
