Installing The Library; Optional: Adding A Power Supply; Planning The Fc Configuration - Sun Microsystems Oracle StorageTek SL48 Getting Started

5 Installing the Library

Slide the Library onto the rails. Secure the front bezel to the rack using
a #2 Phillips screwdriver placed through the small holes in the mounting
bracket to tighten the captive screws on each side of the Library.

Optional: Adding a power supply

With the redundant power supply upgrade kit, the Library will continue
to operate without interruption if either power supply fails.
To install the redundant power supply, remove the cover plate for the
redundant power supply with a #2 Phillips screwdriver. Slide the power
supply into the bay until it is firmly seated. Tighten the three blue
thumbscrews with your fingers to secure the power supply.
Optional: Adding a tape drive
With a tape drive upgrade kit, the Library can hold up to four half-height
LTO tape drives or two full-height tape drives.
Add the new tape drive directly above the currently installed tape drive.
Remove one drive bay cover for a half-height tape drive or two drive
bay covers for a full-height tape drive.
NOTE:
The Library will not operate with a full-height tape drive installed in
the second and third half-height drive bays. Install a full-height tape
drive either in the bottom two drive bays or the top two drive bays.
Slide the tape drive into the bay until it is firmly seated. Tighten the blue
thumbscrews with your fingers to secure the tape drive.
NOTE:
The tape drives are numbered from the bottom up. If your Library
did not come with a tape drive, install the first tape drive in the bottom
drive bay.
6a Planning the FC configuration
The FC tape drive has two FC 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, 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 tape drives for optimum
performance.
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. 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 Library.
NOTE:
See 14 Configuring the FC ports for additional FC configuration
information. See the StorageTek SL24 Tape Autoloader and SL48
Tape Library User and service guide on the documentation CD for
instructions on changing the FC configuration.
