Product Overview 1-1
General Information
General Information
The minimum library configuration consists of a 3U (133.4 mm, 5.25 inches) base
module, designated Module 1, with one robotic hand, a mailslot, a power supply, and
one tape drive (with an option to add a second tape drive and a second power
supply). Tapes reside in a removable 15-cartridge magazine on each side of the
module. Up to three tape slots of the base module left magazine can be designated as
reserved slots to store diagnostic or cleaning tapes.
The external interface for library control is provided by a bridged tape drive. The robot
control is a SCSI Medium Changer device appearing as LUN 1 on a tape drive. The
base module is the smallest fully functional library.
The library can be expanded from one to ten modules. A 2U (88.9 mm, 3.5 inches)
expansion module provides the library an additional capacity of 30 tapes and up to
two tape drives. Expansion modules are designated Module 2 through Module 10.
Modules provide two 15-cartridge magazines, slots for up to two tape drives, and slots
for up to two power supplies.
A graphical user interface (GUI) provides local or remote role-based access control of
the SL150 Library.
■
You access the GUI by entering the host name or IP address into a web browser.
An example of the remote management interface is shown in Figure 1–2.
The library information is presented graphically. Module 1 shows the tape slots in
the left magazine, tape slots in the right magazine, and the available tape drives
between the magazines to represent their physical location at the rear of the
module. The mailslot resides above the right magazine while the robot is above
the left magazine. The magazine representation has identifiers for column number
and row number. There is a separate image for each module in the library.

Library Status Indicators
5 - Tape Drive (Two-Headed Arrow Indicates a Bridged Drive)
■
The base module front control panel has an LCD touch screen panel (operator
panel) and is identified in Figure 1–1. The touch screen provides basic information
about the library and is designed for use as an information point rather than a tool
for maintenance (see Figure 3–34).
The front control panel touch screen is also used to perform basic initialization
setup with an initialization wizard.
Additional library management functions are performed by the administrator
using the remote management interface.
The SL150 Library supports partitions. Each partition has an assigned bridged tape
drive, and each partition behaves as an independent library. All partitions share the
use of the single robot, reserved slots, and mailslot.
Note: Code versions earlier than 2.0 support two partitions, but code
versions 2.0 and later support up to eight partitions.
Class 1 Laser Product Notice
The StorageTek SL150 Modular Tape Library contains a class-1 laser as defined by IEC
60825-1 Ed. 3 (2014) and EN 60825-1:2014.
Warning: Use of controls or adjustments or performance of
procedures other than those specified herein may result in
hazardous radiation exposure.
Library Status Indicators
Library status indicators are located on the front control panel above the left cartridge
magazine (see Figure 1–3) and at the rear of the library on the robot customer
replaceable unit [CRU] in the dark rectangle to the left of the robot lock (see
Figure 3–1).

This chapter introduces general topics for your consideration before performing a
CRU removal or replacement procedure.
Electrostatic Discharge
Be aware of the precautions needed when handling parts. A discharge of static
electricity from a finger or other conductor might damage static-sensitive devices. This
type of damage may reduce the life expectancy of the product.
Electrostatic Discharge Prevention
■
■
Avoid hand contact by transporting and storing products in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free
work areas.
■
Place parts on a grounded surface before removing them from the container.
■
Avoid touching pins, leads, or circuitry.
■
Use proper grounding practices when touching a static-sensitive component or
assembly.
Grounding Methods to Prevent Electrostatic Discharge
Use one or more of the following methods when handling or installing
electrostatic-sensitive parts:
■
Use a wrist strap connected by a ground cord to a grounded chassis.
■
Use conductive field service tools.
■
Use a portable field service kit with a folding static-dissipating work mat.
Note: If you do not have the suggested equipment for proper
grounding, arrange for an authorized reseller to install the part.
SL150 Remote Interface
The process of removing and replacing customer replaceable units (CRUs) relies on
functions and commands in the SL150 remote interface (GUI). It is assumed that you
are familiar with the library section of that interface.
Preparations 2-1
SL150 Remote Interface
You access the remote interface by entering the library host name or IP address in a
supported web browser.
The library view is shown in Figure 2–1. You can enable the Locate Library indicator
from the interface to assist in locating the physical library in the data center. A Help
link is available in the upper right of the screen. The interface provides:
■
Information regarding the library health (operational, degraded, or failed)
■
Access to activity logs
■
Access to diagnostic routines
■
Context menus to perform various operations and obtain additional information

2.
Connect the power cord to each installed power supply.
3.
Follow the power on procedures (see "Power System Behavior").
Power System Behavior
The behavior of the SL150 library when AC power is applied to the system power
supplies depends on how the tape library was powered down from the previous
powered-up state. The system BIOS is set to recall the last power state from AC loss
(such as a utility power outage, removal of the AC power cord, or powering off a PDU
or power strip).
When AC power is restored, the system turns on for about 4 seconds while the system
BIOS determines the library power state when AC was lost.
■
■
If the tape library was powered up when AC was lost, it remains in the powered-on
state and the boot sequence starts.
If the tape library was powered down when AC was lost, it returns to the
powered-down state about 4 seconds after AC power restoration.
A controlled powered-down is performed from the SL150 remote management interface
or physical library power button (the touch screen GUI is also involved). If power is
lost after a controlled power-down, the BIOS resets to power on for about 4 seconds
when AC power is restored. The tape library returns to the powered-off state until the
power button is pressed to apply power to the tape library.
A forced power-down of the tape library is performed by pressing and holding the
power button until the library powers down (approximately 10 seconds). If power is
lost after a forced power-down, the library does not perform the BIOS power on for 4
seconds after AC power restoration. The tape library remains in the powered-down
state until the power button is pressed to apply power to the tape library.
3-34 StorageTek SL150 Modular Tape Library Customer Replaceable Unit Guide
Power System Behavior
To Power-on the Library
1.
Make sure the robot is not locked.
2.
Make sure the floor is installed in the bottom library module.
3.
Press the power switch on the base module to initiate a restart, if necessary.
Caution: Do not manually remove a cartridge magazine while the
library is performing the restart. Perform a manual magazine
removal only when the library is operational and offline.
See Appendix A, "Startup" for a description of the process. Library initialization
occurs during startup and includes movement of the robot to determine the
number of modules and tape drives in the library. If library initialization fails, the
tape drive ports are not enabled.
Note: In a bridged library, the host will not be able to see the library
if the bridged drive ports are not enabled. Perform troubleshooting
procedures in the user’s guide to resolve a bridged drive problem.
Startup duration varies based upon the number of library modules. After
completion, the Home screen appears on the touch screen.
Figure 3–34 Home Screen
Illustration Legend:
1 - Library Health
4.
Check the OK indicators on all CRUs.
5.
Verify that the library health state is operational from the touch screen (see
Figure 3–34) or the SL150 remote interface.
Removal and Replacement 3-35
CRU Return
If the health state is degraded or failed, consult the troubleshooting section of the
user’s guide to assist with resolving the problem.
To Validate Library Operation
1.
Perform an operational check of replaced CRUs, as applicable:
Test the panel for general operation (locate light, touch screen, open the mailslot,
and so forth).
Confirm that the library recognizes the module controller (Modules area of the
touch screen or Library area of the SL150 remote interface).
2.
Run the offline self tests from the SL150 remote interface (refer to the StorageTek
SL150 Modular Tape Library User’s Guide or the Help system for instructions).
3.
Set the SL150 library to the online state and log out of the SL150 remote interface.
Note: After CRU replacement, run application commands to
ensure that the library and drive applications are synchronized. See
your host tape application documentation for guidance.
CRU Return
Return the robot and tape drive tray CRUs to Oracle. Instructions should have been
provided regarding the process to return the specific CRU.
Dispose of all other CRUs or recycle them, as appropriate.
3-36 StorageTek SL150 Modular Tape Library Customer Replaceable Unit Guide
A
Startup
A
The SL150 library is typically started up when power is applied (the power cord is
plugged in or the external power is switched on). If the library was manually powered
down (from the front panel power switch or the shutdown function of the remote
management interface), pressing the front panel power switch starts the library.
During library startup, the following steps are performed:
1.
The robot is unparked.
2.
The hand fully retracts.
3.
The robot moves from the top to the bottom of the entire library. By starting at the
top and moving down one module at a time, the robot determines the order of the
modules.
4.
The wrist sweeps through its full range of motion.
5.
The hand moves through the full track range.
6.
The reach mechanism extends and retracts.
7.
Magazines are latched.
8.
A full library audit is performed.
You can observe the progress of a library audit from the Library view in a web
browser. Tape slots that the library has not audited are greyed-out while audited
tape slots are active (a barcode icon is present in the slot). When you move the
cursor over the active slot the tape location and barcode information is shown. If
the barcode information has a value of unreadable, the barcode label is out of
specification, damaged, or it does not exist.
Be aware that the barcode icon is a facsimile and does not represent the actual
cartridge barcode.
When the audit completes and all drives are ready, the library is operational.
