HP StorageWorks MSL Library Extender user guide 9

1 Features and overview

The Library Extender combines two HP StorageWorks MSL Tape Libraries to create a single extended library. Before installing the Extender, the Libraries must be installed in the rack rails supplied with the Libraries in adjacent rack locations, one Library above the other. See the example shown in Figure

Figure 1 Library Extender installed with two MSL4048 Tape Libraries

The Extender occupies the lower half-height drive bay of the upper Library and the top half-height drive bay of the lower Library.

The upper Library controls the extended library and is called the master Library. The extended library uses only the master Library OCP, USB port, and Ethernet connection.

The lower Library is controlled by the master Library. The lower Library OCP, USB port, and Ethernet connection are not used by the extended library.

Tape drives

Tape drives are numbered starting with the lower Library and continuing with the master Library.

Any tape drive in the extended library can host the SCSI Library interface. The default is the lowest tape drive in the lower Library.

Power supply redundancy

Both Libraries must have a working power supply for the extended library to operate. To have total power supply redundancy, both Libraries must have working redundant power supplies. In an extended library, if only one Library has redundant power supplies installed, the extended library will continue to operate in case of a power supply failure in that Library. An extended library containing an MSL2024 cannot have total power supply redundancy because the MSL2024 only has one power supply.

Features and overview12

Using the Extender with the Encryption Kit

The HP StorageWorks 1/8 G2 & MSL LTO-4 Encryption Kit provides secure generation and storage of encryption keys.

An extended library will only access the key server token in the master Library.

NOTE:

The USB port in the lower Library is not active.

The extended library must contain at least one LTO-4 tape drive to use the Encryption Kit. LTO-4 tape drives can be in any valid drive location in the extended library.

If combining two Libraries that were both using the Encryption Kit, you can copy the keys from one of the tokens onto the other so the token that will be used in the extended library has the keys to read tapes from both Libraries. See the section on combining keys from multiple key server tokens in the HP StorageWorks 1/8 G2 and MSL Encryption Kit user guide for instructions. To download the user guide from the HP website, see Related documentation, page 67.

If you separate an extended library that uses the Encryption Kit and will have at least one LTO-4 tape drive in each of the Libraries, you can copy the encryption keys on the token from the extended library to a new token so both Libraries have access to all of the keys. See the HP StorageWorks 1/8 G2 and MSL Encryption Kit user guide for instructions. To download the user guide from the HP website, see Related documentation, page 67.

Extended libraries and logical libraries

When the Extender is installed, the extended library is configured as a single logical library. An extended library cannot be partitioned into multiple logical libraries.

If the Libraries are ever separated, each individual Library will become a single logical library until reconfigured.

Installation overview

Successful installation of the Extender requires performing key steps in the order specified in Chapter

3, page 27.

1. Obtain the latest firmware for each Library from the HP website and download it into each Library

separately.

2. Enable extended mode on each Library.

3. Power off both Libraries.

4. Position the Libraries in the rack on their own rack rails.

5. Align the two Libraries using the alignment gauge.

HP StorageWorks MSL Library Extender user guide 13

6. Move the tape drives, if necessary, to open the drive bays that will be used by the Extender.

NOTE:

In an MSL4048, a full-height tape drive will only operate in the two upper or two lower half-height drive locations. Do not install a full height tape drive in the middle half-height drive bays of an MSL4048 Tape Library.

7. Install the Extender.

8. Tighten the captive rack attachment screws on the front of the Libraries.

9. Power on both Libraries and verify that the three Extender LEDs are illuminated.

Rack stability

Rack stability protects personnel and equipment.

WARNING!

To reduce the risk of personal injury or damage to equipment:

• Extend leveling jacks to the floor.

• Ensure that the full weight of the rack rests on the leveling jacks.

• Install stabilizing feet on the rack.

• In multiple-rack installations, fasten racks together securely.

• Extend only one rack component at a time. Racks can become unstable if more than one component

is extended.

Features and overview14

2 Configuring and operating an extended library

This chapter provides information about extended library configuration and operation tasks that are different from a single Tape Library.

If you are installing the Extender for the first time, read this chapter for reference after installing the Extender following the instructions in Chapter 3, page 27.

TIP:

Check the Help screens in the RMI for additional information. The help pages are updated with most firmware updates and often contain technical details that are not contained in this document. To access RMI help, click Help on the right side of the Web page banner, as shown in Figure

2 on page 15.

Figure 2 Help available from the RMI

Powering on the extended library

To power on the extended library, power on each of the Tape Libraries from their OCPs. The Libraries can be powered on in either order. The initialization sequence is faster if the lower Library is powered on first.

HP StorageWorks MSL Library Extender user guide 15

Figure 3 Press the power buttons on both Libraries to power on the extended library

If the master Library is powered on first, it will prompt the user to power on the lower Library. If the lower Library is powered on first, it will remain in an uninitialized state until it receives an initialization command from the master Library.

Powering off the extended library

To power off the extended library, power off the master Library. The master Library will power the lower Library off. If the master Library is powered off with the emergency power off procedure or the power cord is removed, the lower Library will lose communication with the master Library and must be powered off by depressing its power button and holding it for at least 10 seconds.

Figure 4 Press the power button on the master Library to power off the extended library

Configuring and operating an extended library16

Viewing identity information

To view detailed information about both Tape Libraries and the Extender, use the RMI Identity >

Library page or the master Library Info > Identity OCP screen.

Figure 5 Identity > Library page

The Library Information pane displays information about the master Library and the extended library.

• Serial Number — the electronic serial number for the master Library. The part of the serial number

before the '_' character, should match the serial number printed on the Library label, located on

the pull out tab on the back of the Library. The part of serial number after the '_' character encodes

the extended library components as follows:

• X — signifies that the master Library is in extended mode

• ml — shows the height of the master and lower Libraries, respectively

• 2 is an MSL2024

• 4 is an MSL4048

• 8 is an MSL8096

In the example shown in Figure 5, page 17, with the serial number DEC716067E_X84, the master

Library serial number is DEC716067E, the master Library is an MSL8096 and the lower Library

is an MSL4048.

• Product ID — how the device identifies itself to the host computer. This will always be MSL G3

Series.

• Random — the device will not automatically load and unload tapes. Instead, it will wait for

commands from the backup software or the OCP to load and unload tapes.

• Sequential — the device will automatically unload the tape in the drive when the host software sends an unload command to the drive and then automatically load the tape from the next highest sequentially numbered full slot.

• Loop — in Loop mode, the Library will load the tape from the lowest numbered full slot after the tape from the highest numbered full slot is unloaded. If Loop is not listed, the Library will stop automatically loading and unloading tapes after the tape from the last full slot is unloaded.

CAUTION:

Since loop mode will endlessly cycle through the tapes, it is possible to overwrite old data. Make sure that there are enough tapes in the Library or that the tapes are regularly rotated in and out to ensure that data you want to save is not overwritten.

• Autoload — the device will automatically load the tape from the lowest numbered full slot on power up.

• WWide Node Name — a world wide unique identifier that the Library reports over SCSI and

may be used by operating systems or software applications to identify and track the Library.

In extended mode, the only functions available through the lower Library OCP are disabling extended mode and adjusting the display contrast (MSL4048 or MSL8096 only).

HP StorageWorks MSL Library Extender user guide 21

Figure 8 Configuration > System RMI page for an extended library with an MSL8096 master Library and an MSL4048 lower Library

• Library LUN Hosted By Drive — Specifies the master tape drive for the extended library through

which the host system controls the extended library. The default is the lowest numbered tape drive in the extended library. If an extended library has only one tape drive, it is the master drive for the extended library. If an extended library has more than one tape drive, you may specify the master. The number is the physical drive number.

• Library Mode — Specifies the library mode for the extended library. The default mode is Automatic.

The extended library supports three behavior modes: Random, Sequential, and Automatic. The extended library automatically detects the required mode from the series of SCSI commands it receives; however, you can also change the mode. Select the operating mode based on the capabilities of the software controlling the tape cartridges.

Random mode — In Random mode, the device does not automatically load tapes into the tape drives; it waits for commands from the software or operator to load and unload tapes. Random mode is used with a full featured or a robotics-aware backup application and is the most common mode of operation. Your backup software must support robotics, which may require an additional software module.

Sequential mode — In Sequential mode, the device automatically loads and unloads tapes from the drive. Sequential mode is used when the backup software is NOT robotics-aware or was designed for standalone drives only.

When Extended mode is enabled, the extended library will only use the lowest-numbered tape drive in the extended library.

The operator begins the sequence by loading the desired tape into the tape drive. When a tape is unloaded, the device automatically removes the tape from the drive, returns it to its original slot, then loads the tape from the next available higher numbered slot.

To further determine how tapes are loaded into the tape drive while in Sequential mode, you can set the Loop and Autoload options.

Configuring and operating an extended library22

• When Autoload mode is set, the device automatically loads the cartridge from the lowest-

numbered full slot into the tape drive. It then follows standard sequential operation.

• When Loop mode is on, the original first cartridge in the sequence is reloaded after the device

has cycled through all available cartridges. If Loop mode is off and the last cartridge has been unloaded, the device stops loading cartridges until you load another manually.

CAUTION:

Use caution when choosing Loop mode because it makes it possible to overwrite data on previously written cartridges.

Automatic mode: In Automatic mode, the device switches from Sequential mode into Random mode when it receives certain SCSI commands. Automatic mode is the default setting.

• Reserved Slots — The number of slots in the extended library that are not available to the backup

software. You can store cleaning cartridges in reserved slots, or leave reserved slots empty. The slots are reserved from the highest slot number down. The default is 0 reserved slots so the maximum number of slots are available to the host. The extended library must have at least two slots that are not reserved.

• Mailslot Configuration for the master Library and lower Library

• MSL2024 and MSL4048 — configures the mailslot in the lower left magazine as a mailslot

or storage slots. The MSL2024 mailslot has one slot; the MSL4048 mailslot has three slots. Enabling the mailslot will reduce the total number of storage slots. The default is disabled.

• MSL8096 — configures the mailslot in the lower-left magazine and upper-right magazine as mailslots or storage slots. Enabling a mailslot will reduce the number of storage slots. The default is 0 mailslots enabled.

You can enable either or both of the mailslots by selecting the number of mailslot slots in the Mailslot Configuration drop down list.

• 0 disables both mailslots.

• 3 enables the lower-left mailslot only.

• 12 enables the upper-right mailslot only.

• 15 enables both mailslots.

CAUTION:

Enabling or disabling a mailslot will re-number the storage slots in one or both of the Libraries. After enabling or disabling any mailslots, update the backup software inventory. You may also need to re-configure the backup software to adjust the number of storage slots and presence of the mailslot.

• Auto Clean Enabled — When auto clean is enabled, the device automatically loads a cleaning

cartridge when a tape drive needs to be cleaned. The device identifies a tape cartridge as a cleaning cartridge if it has a bar code label that starts with CLN or after an unlabeled cleaning tape has been loaded into the tape drive.

The Library can use a cleaning cartridge from any slot, even if the slot is reserved. The Library keeps track of the usage count for each of the cleaning cartridges. When multiple cleaning cartridges are available, the Library will first select a cleaning cartridge with an unknown usage count so the Library can start tracking the cartridge's usage count. If the Library knows the usage count for all of the cleaning cartridges, the Library will select the one with the highest usage count.

HP StorageWorks MSL Library Extender user guide 23

Auto cleaning is disabled by default. You can enable automatic cleaning even if there are no cleaning cartridges in the device. In this case, the device will display a warning message.

CAUTION:

Only enable automatic cleaning in either the backup application or the Library, not both.

• Barcode Label Length Reported to Host — the number of bar code characters reported to the host

application. This option provides compatibility with libraries and software with more limited bar code reading capabilities. The default is 8.

• Barcode Label Alignment Reported to Host — configures the end of the bar code label characters

to report to the host application when reporting fewer than the maximum number of characters. For example, when reporting only six characters of the bar code label 12345678, if the alignment is left, the Library will report 123456. If the alignment is right, the Library will report 345678. The default is left, which is used by most software applications.

• Ignore Barcode Media ID — when disabled (default), the barcode Media ID on the tape cartridges

will be checked by the Library. The Library will only allow appropriate tape cartridges to be loaded into tape drives. The barcode Media ID is the last two characters of the barcode. For example, an LTO-4 labeled cartridge will not be allowed to move into an LTO-3 tape drive. When Ignore Barcode Media ID is enabled, the Library will move any tape to any tape drive. If the cartridge is incompatible with the tape drive, a message will be displayed. HP strongly recommends that all tape cartridges have barcodes with the correct Media ID.

• Magazine access using front panel - Admin password required — when enabled (default), the

Administrator password is required to remove the magazines from the OCP. When disabled, the magazines may be removed using the OCP without entering a password. Robotic motion is prevented when magazines are removed. Allowing unauthorized removal of magazines can leave the Library in a state where backup operations cannot continue if all magazines are not properly replaced in the Library. The default is to require the Administrator password.

• Extended mode enabled — select the box to enable extended mode; clear the box to disable ex-

tended mode. The configuration will take effect when the Library power is cycled. Extended mode must be enabled or disabled in both Libraries.

Extended mode can only by disabled in the lower Library from the OCP.

System configuration changes are only applied after the Apply Selections or the Submit button is selected. After making the selection, a warning page informs you of the impact of the proposed change. In some cases a pop-up screen asks you to confirm the change. Many changes also require the device to reboot. You may need to click Refresh to see the changes.

To find Library firmware that supports the Library Extender:

HP StorageWorks MSL Library Extender user guide 25

1. Browse to http://www.hp.com/support/msl_extender.

2. Select and download the newest firmware version for your Library without _LX_ in the filename.

NOTE:

The first time you install the Extender you must update the firmware in each Library individually. For future firmware updates, when extended mode is enabled you can update the firmware for both Libraries at the same time with the Extender firmware package. Updating with the firmware package is not only faster and easier, but ensures that the Libraries have compatible firmware versions. When updating firmware for the extended library, select the file with _LX_ in the filename.

The library extender firmware package can be installed from the RMI Support > Firmware page, from the OCP Support > FW Upgrade > By USB screen, or by using HP Library & Tape Tools version 4.8 or newer.

Tape drive firmware is updated through the master Library for all tape drives in the extended library. See the HP StorageWorks MSL2024, MSL4048, and MSL8096 Tape Libraries user and service guide for instructions on updating tape drive firmware.

NOTE:

Before downgrading the Library firmware to a version that does not support the Extender, disable extended mode in both Libraries and remove the Extender.

Running diagnostic tests

Diagnostic tests for the extended library

• Demo — moves cartridges from the slots to the drives and back. At the end of the test the cartridges

are returned to their original slots. The demo is executed from the RMI or OCP.

• Slot to slot — shuffles the cartridges between slots to exercise the robot. At the end of the test the

cartridges are NOT returned to their original slots. The slot test is executed from the RMI or OCP.

• Library Extender cycle test — moves the first available cartridge in the master Library to the lower

Library and back, exercising the robotics in both Libraries and the Extender, with cartridge exchanges in both directions. At the end of the test the cartridge is returned to its original slot. The Library Extender cycle test is executed from the RMI or OCP.

• Wellness test — exercises all extended library functionality except the external interfaces. The

wellness test is executed from the OCP. For instructions on setting and running the wellness test, see The wellness test, page 44.

The demo and slot to slot tests are intended to show the device operating. For Library Extender service and diagnostics, execute the Library Extender cycle test. To verify installation and repairs, execute the wellness test.

Figure 31 Aligning the Extender tab in the Library slot

The tab on the Extender must be inserted in the slot on the master Library, as shown in Figure 31, for the Extender to seat properly in the connector in the master Library. If the tab is under or to the left of the bracket, the electrical connection will not be completed.

• The master and lower Libraries have the current firmware versions.

If Library Extender status LED (2), is flashing:

• The Library Extender may be initializing. Check the OCP for status messages and wait a few

minutes for the initialization process to complete. Initialization can take up to 15 minutes.

• The Library Extender has failed with a hard error. See the master Library log to find the error code.

If the lower Library connection status LED (3), is not green, verify the following:

• The lower Library is powered on.

•

If the lower Library is an MSL4048, its power supply status is Good .

• Extended mode is enabled in the lower Library.

• The rack rails are straight and the front bezel screws attaching both Libraries to the rack are secure.

The back planes of the two Libraries should be aligned in the same plane. If the master Library is set further back the plug on the Extender might not reach the connector on the lower Library.

• The master and lower Libraries have the current firmware versions.

The Library Extender cycle test

The Library Extender cycle test verifies that the Library Extender can transfer cartridges between Libraries. The Library Extender cycle test moves the first available cartridge in the master Library to the lower Library and back, exercising the robotics in both Libraries and the Extender, with cartridge exchanges in both directions. When the test is complete, the cartridge is returned to its original slot. The Library Extender cycle test is executed from the RMI or OCP.

The wellness test

The wellness test exercises all Library and tape drive hardware, except the external connections, and is useful for verifying that a device is working correctly. The wellness test requires operator interaction with the mailslot so cannot be initiated from the RMI.

Using diagnostic tools and troubleshooting44

For complete testing, enable a mailslot and ensure that at least one of the top-row corner slots in one of the Libraries contains a tape cartridge.

Table 4 Top-row corner slot positions

Using diagnostic tools and troubleshooting46

MSL8096 toprow corner slots with mailslot disabled: 45, 48, 93, 96

IMPORTANT:

The Library will remove any tape cartridges from the tape drives and go offline when running the wellness test. Verify that any applications using the Library have completed before starting the wellness test.

You can have the Library run up to 10 cycles of the wellness test. The wellness test exercises all enabled tape drives in the extended library.

The wellness test requires operator interaction and can only be run from the OCP. During the wellness test:

1. The operator starts the wellness test from the master Library OCP. The administrator password is

required.

2. The master Library performs a self test, verifies that it can communicate with the tape drives and

the Extender, and then the lower Library performs a self test.

3. The Library returns any tape cartridges from the tape drives to their home slots. If the home slot

for a cartridge is not known, the Library will move the cartridge to the mailslot and prompt the operator to remove it.

4. The Library prompts the operator to enter the number of cycles to run the test.

5. The Library opens the lowest-numbered mailslot in the extended library, which will generally be

in the lower Library, and prompts the operator to insert a scratch cartridge.

NOTE:

In the MSL8096, the 12-slot mailslot does not pop out; the operator must open it.

6. The operator inserts a scratch cartridge into the lowest-numbered mailslot. If no mailslots are

enabled or the operator closes the mailslot without inserting a cartridge into the lowest-numbered mailslot, the Library will perform a shortened version of the wellness test, skipping Step 7.

HP StorageWorks MSL Library Extender user guide 47

7. The Library loads the scratch cartridge into the first tape drive, unloads the scratch cartridge from

the tape drive, and returns the scratch cartridge to the mailslot. If the operator selected to test all of the tape drives, the Library will load the scratch cartridge into each tape drive before returning it to the mailslot.

8. The Library moves the tape cartridge from the four top-row corner slots of both Libraries to the

tape drive load point and then returns the tape cartridge to its slot. If none of the top-row corner slot positions of either Library contains a tape cartridge, the test stops and the Library displays an error message.

9. If additional cycles remain to be run, the test will return to Step 7 if there is a tape cartridge in

the mailslot or Step 8 if there is not a cartridge in the mailslot.

10. At the conclusion of the test, the Library pops open the mailslot and waits for the operator to

remove the scratch tape. In the MSL8096, if only the 12-slot mailslot is configured, the Library will prompt the operator to open the mailslot and remove the scratch tape cartridge.

11. The Library displays the test completion status, including any recoveries or errors that may have

occurred.

Libraries, as shown in Figure 34, page 57.

Figure 34 Removing the Extender

2. Pull the Extender straight out of the Libraries.

To store or ship the Library Extender, repackage it in the original packaging materials as shown in

Repackaging the Library Extender, page 61.

Preparing the Libraries to operate as separate Libraries

Each Library must have at least one tape drive. Skip this procedure if you do not need to relocate a tape drive from one Library to the other.

IMPORTANT:

To avoid damage to the Library, ensure that the tape drive is powered off before removing it from a Library.

HP StorageWorks MSL Library Extender user guide 57

1. To remove a tape drive from its current location, loosen the blue captive thumbscrews on the tape

drive.

2. Pull straight back on the tape drive handle while supporting the bottom of the tape drive to remove

it from the Library.

3. If necessary, remove one or two drive bay covers.

4. Slide the tape drive into its new drive bay. Tighten the blue thumbscrews with your fingers to

secure the tape drive in the Library.

Replacing drive bay covers

Use a #1 Phillips screwdriver to secure drive bay covers over any open tape drive bays.

Connecting the Ethernet cable

To use the RMI with the lower Library, insert one end of an Ethernet cable into the Ethernet port on the back of the Library. Plug the other end into an Ethernet LAN port.

Powering on the Libraries

Power on each Library from its OCP. They no longer communicate with each other and must be configured and operated separately.

Copying the key server token

Skip this section if the extended library is not using the HP StorageWorks 1/8 G2 and MSL Encryption Kit.

The encryption keys used to read and write encrypted data are stored on a USB key server token. In the extended library, encryption keys are stored in the key server token installed in the master Library.

Servicing the Library Extender58

When the Libraries are separated, each Library will need its own key server token with the keys to read tapes that were written by the extended Library.

To create a second key server token with the keys used by the extended library, follow the instructions for backing up the key server token data in the HP StorageWorks 1/8 G2 and MSL Encryption Kit user guide.

Insert the key server token into the USB port on the master Library.

Reconfiguring the Libraries

When extended mode is disabled, each Library will have a mix of settings from the extended library, default values, previous values, and new values. Use the OCP or RMI to check the settings for each Library and reconfigure them if necessary. See the HP StorageWorks MSL2024, MSL4048, and MSL8096 Tape Libraries user and service guide for more information about the settings and configuring the Libraries.

Settings retained from the extended library

The following settings are retained by both Libraries from the extended library:

• Administrator password

• SCSI tape drive addresses

• Fibre Channel drive settings

• Date and time

• Email notification

• Encryption — remains On if LTO3 or LTO4 tape drives are installed

Settings that are set to default values

The following settings are set to default values:

• Mailslot configuration — all mailslots disabled

• Reserved slots — no reserved slots

• Library mode — Automatic

• Autoload — No

• Loop — No

• Logical libraries (partitioning) — Off

• SCSI master drive — the lowest tape drive in each Library

Settings where the lower Library reverts to earlier values

For the following settings, the upper Library retains the settings from the extended Library and the lower Library reverts to the settings it had before extended mode was enabled:

• Network settings

• Barcode format reporting

• Auto clean

• SNMP

• Log tracing configuration

• Allow magazine access without the Administrator password

• Ignore barcode media ID

HP StorageWorks MSL Library Extender user guide 59

Special cases

• OCP contrast setting (MSL4048 and MSL8096) — each Library retains the setting it had before

extended mode was enabled.

• Drive power — In the extended library, one of the tape drives is configured as the SCSI master

drive. The SCSI master drive can be in either Library. When extended mode is disabled, the Library that hosts the tape drive that was configured as the

SCSI master drive in the extended library retains the drive power settings from the extended library. Thus, if any tape drives in this Library were powered off, they will continue to be powered off.

In the other Library, all tape drives are powered on.

Removing a cartridge from the Extender

If the extended library cannot return a tape to one of the Tape Libraries, you may need to remove it manually.

1. Remove the Extender from the tape Libraries.

a. Using a #1 Phillips screwdriver, loosen the four thumbscrews that secure the Extender to the

Tape Libraries.

b. Pull the Extender straight out of the Libraries as shown in Figure 35, page 60.

Figure 35 Removing the Extender

2. If the tape cartridge is near the front of the Extender, grasp the cartridge with your hand and

pull it straight out of the Extender.

Servicing the Library Extender60

CAUTION:

Removing the top of the Extender will require its replacement. Only remove the top of the Extender to retrieve a cartridge when all other removal attempts have failed.

To remove a cartridge that is stuck in the back of the Extender:

a. Using a #2 Phillips screwdriver, loosen the six screws marked with arrows on the sheet metal

on top of the Extender.

b. Remove the top sheet metal.

c. Remove the cartridge.

d. Replace the sheet metal and tighten the screws.

Repackaging the Library Extender

IMPORTANT:

Shipping the Extender without properly repackaging it can damage the Extender.

Follow these steps to package the removed Library Extender for storage or shipment.

To package the removed Library Extender for storage or shipment:

1. Insert the cardboard support in the space between the top and bottom of the extender.

2. Place the extender on the base position of the cardboard wrapper.

HP StorageWorks MSL Library Extender user guide 61

3. Fold the tab on the cardboard support piece down, and then fold the ends of the wrapper over

the front and back of the Extender.

4. Wrap the sides of the wrapper around the sides of the Extender.

5. Secure the wrapper with packaging tape.

6. Place the foam caps around the front and back of the Extender.

Servicing the Library Extender62

7. Attach a foam side support on each side of the Extender.

8. Place the protected Extender in the shipping box.

HP StorageWorks MSL Library Extender user guide 63

9. Secure the box with packaging tape.

Releasing the magazines manually

If you cannot remove the magazines via the OCP or RMI, do the following:

1. Power off both Libraries.

2. Unplug the power cord from the Library with the magazines to be removed.

Servicing the Library Extender64

3. From the back of the device, find the access hole for the magazine to be released. See Figure

36, Figure 37, and Figure 38.

HP StorageWorks MSL Library Extender user guide 65

4. To manually release a magazine, push the end of a small metal pin or straightened paper clip

until you feel some resistance, about 1.5 cm (0.6 inch), into the magazine access hole to depress the magazine release tab. While holding in the release tab, have a second person attempt to pull the magazine out of the front of the unit. For the MSL4048 and MSL8096, all magazines on a side are released and may be removed at the same time. See Figure 39.

Figure 39 Releasing the magazine

Push a metal pin or paper clip into the access hole.1.

Pull the magazine out of the front of the unit.2.

IMPORTANT:

Do not force the pin once you encounter resistance. Doing so can damage the Library.

5. Repeat Step 4 for the other magazine if necessary.

6. If other tapes are still in the device, or if you were unable to manually remove the magazines,

contact HP customer service for assistance.

B Electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

Preventing electrostatic damage

To prevent electrostatic damage, observe the following precautions:

• 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 workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly. See

Grounding methods.

Grounding methods

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 workstation or computer chassis.

Wrist straps are flexible straps with a minimum of 1 megohm (±10 percent) resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet

when standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an HP authorized reseller install the part.

NOTE:

For more information on static electricity, or assistance with product installation, contact your HP authorized reseller.
