# 6 Monitoring and Diagnostics

Monitoring library operations for component failures and operational problems is one of the few regular tasks that you need to perform when operating an StorageTek SL150 Modular Tape Library. The library is designed to operate automatically, under the control of host software. So, under normal circumstances, little or no operator intervention is needed. You merely need to monitor the system for abnormal conditions. Careful monitoring and prompt corrective actions minimize library downtime and maximize the availability of your data.

This section starts by outlining the main approaches to monitoring the health and operations of the StorageTek SL150 Modular Tape Library and the interfaces that support the,:

- Using SL150 User Interfaces

- Using Simple Network Management Protocol (SNMP)

Then it describes the processes for handling any problems that you detect:

- Troubleshooting

- Getting Parts and Technical Support.

## Using SL150 User Interfaces

The SL150 user interfaces provide a comprehensive set of remote and local monitoring tools. This section explains how to carry out each of the following tasks:

- Monitor the Browser-based User Interface

- Check the Local Operator Panel

- Check Library and Component LED Indicators

### Monitor the Browser-based User Interface

The remote, web-based user interface is the main tool for monitoring the SL150 Modular Tape Library. It provides straightforward monitoring and troubleshooting tools and a comprehensive set of management interface. It is accessible from any workstation that has a web browser installed and network access to the library. Routine system monitoring is as simple as Checking the System Dashboard and Checking Health Details.

#### Checking the System Dashboard

To monitor the SL150 tape library, you need only glance at the Library Health and host connection state indicators found at the top of every screen in the remote user interface. These two indicators summarize the overall operating condition of the library and the status of its connection with its host system.

The library Health indicator represents the aggregate state of every component in the system. When the library is Operational, all library components are themselves Operational and the library as a whole is fully functional and available for use. When the library is Degraded, the library is working and available for use, but one or more components have either failed or been degraded by subcomponent failures. When the library has Failed, it is unusable. Either a critical, non-redundant component has failed or a faulty bridged drive has broken the control-data path between the library and the host.

The library host-connection status indicator shows whether the Library is Online and available to host applications or unavailable due to maintenance or system faults. The library may be unavailable for any of the following reasons: the Library is Offline, a Magazine is Open, the Library is Initializing, the Library is Powering Down, the library is undergoing Maintenance, library Start-up Failed, or the Library is Inoperative and needs to be restarted.

#### Checking Health Details

If the library Health indicator shows that the library is Degraded or Failed, click on the indicator to view details. The remote user interface displays a fault table with a Date and Time, a Fault Code and Fault Name a list of Suspect Components, and a Recommended Action for correcting each problem.

Faults can have side effects that make other, healthy components appear faulty. So the Suspect Components field of each fault record lists possible causes in order of probability. For example, if the expansion controller on module 3 has lost its connection to the library controller and the motherboard, chassis, and power supply of the same module appear to have failed, the Suspect Components field will list the module interconnect cable that links module 3 to the library controller first, followed by the other, less-likely components.

For more information on interpreting library health information, see "Troubleshooting".

### Check the Local Operator Panel

The SL150 local operator panel lets you check on library status and configuration when you are working directly with the hardware and cannot easily use the browser-based user interface. The local operator panel can be especially valuable when you Check Library and Component LED Indicators.

In the operator panel, the Health and host connection state indicators are again located at the top of the every screen. If the library Health indicator shows that the library is Degraded or Failed, click on the indicator to view details.

The local operator panel displays the same health details as the remote user interface, but in abbreviated form: a Fault Code that includes the fault name, a list of Suspect Components, and a corresponding Recommended Action:

For more information on interpreting library health information, see "Checking Health Details" and "Troubleshooting".

### Check Library and Component LED Indicators

When you have physical access to the library, you can monitor its overall status and the status of individual Customer Replaceable Unit (CRU) components by checking the indicators on the library base module. A pair of light-emitting diode (LED) indicators shows the health of the library and the health of each of its customer-replaceable components:

| If the OK LED is green and the alert (!) LED is off, the library or component is fully Operational.
| If the OK LED is green and the alert (!) LED is amber, the library or component is Degraded. It is still operating but with reduced functionality.
| If the OK LED is off and the alert (!) LED is amber, the library or component has Failed and cannot perform its function.

Library health indicators are located on the front panel of the library base unit at upper left, alongside the power button. Health indicators for the customer-replaceable local operator panel are found alongside the upper left corner of the touch-screen display.

The rear panel of the base unit also holds library health indicators health indicators, this time located at the top just left of center. Additional indicators show the status of customer replaceable units (CRUs), such as the robot/library controller, the power supplies, and tape drives.

The module controller in the upper right corner of the rear panel of an expansion module holds an additional set of LED health indicators.

## Using Simple Network Management Protocol (SNMP)

Network management applications can monitor the SL150 Modular Tape Library using the Simple Network Management Protocol (SNMP). You can configure the library's SNMP agent to automatically send traps that alert network management stations to faults and configuration changes.

The SL150 library supports both version 2c and version 3 of the SNMP standard, so you can select the version that best meets your needs. Version 2c is backward compatible with earlier versions of the standard but is insecure (authentication credentials—community strings—and management data are exchanged in clear text). SNMP version 3 is not backwards compatible but supports a more secure authentication method and encryption of the management data.

The SNMP tab of the Settings screen lets you carry out the following SNMP configuration tasks:

- Adding an SNMP User

- Updating an SNMP User

- Deleting an SNMP User

- Adding an SNMP Trap Recipient

- Updating an SNMP Trap Recipient

- Deleting an SNMP Trap Recipient

- Sending a Test Trap

- Downloading the Management Information Base (MIB).

For detailed information on SNMP and Oracle's StorageTek Modular Libraries, see the SNMP Reference Guide in the SL150 Modular Tape Library Customer Documentation Library.

## Troubleshooting

To diagnose library problems, proceed as follows:

1. Try to Log In to the remote, browser-based user interface.

2. If you log in successfully, Take the Library Off Line, and Use the Health Table, as described in the next section.

3. If you cannot log in to the remote, browser-based user interface, go to the library and Check the Local Operator Panel.

4. If the local operator panel is working and the remote user interface is not, make sure that an Ethernet cable is connected to NET MGT port 0 at the rear of the library. Check for network problems.

5. If you found and corrected network problems, open a web browser and Log In to the remote user interface, then Take the Library Off Line and Use the Health Table to check the library for problems.

6. If the local operator panel is also not working, make sure that the library has power. Make sure that a power cord is correctly connected to each power supply and to a working, data-center power outlet.

7. If the library is not connected to power, correct the problem. Stop here.

8. If the library is connected to power, Check Library and Component LED Indicators.

9. If an amber PS (power supply) LED is lit or if both power supply LEDs are dark, replace the power supply, as described in the StorageTek SL150 Modular Tape Library Customer Replaceable Unit Guide. Stop here.

10. If an amber Robot Module LED is lit or if both robot LEDs are dark, replace the robot as described in the StorageTek SL150 Modular Tape Library Customer Replaceable Unit Guide. Stop here.

11. If the robot module is OK, Restart the Library, and repeat this procedure.

12. If you have resolved the problem after restarting the library and repeating the above diagnostic steps, stop here.

13. If problems persist after you have restarted the library and repeated the above diagnostic steps, go to "Getting Parts and Technical Support", Check for Relevant Knowledge Articles, and then, if necessary, Create a Service Request.

### Use the Health Table

The library Health indicator at the top of every SL150 browser-based user interface screen is your main diagnostic tool. If the Health indicator shows that the library is Degraded or Failed, proceed as follows:

1. Click on the Degraded or Failed indicator.

   The user interface displays a Library Health table with a row for each fault detected on the system. Each row contains fields for the Date and Time, Fault Code, and Fault Name associated with the problem, a prioritized list of Suspect Components that might be causing the problem, and the Recommended Action for correcting the problem.

2. For each fault record in the table, Step Through the Suspect Components Listed in the Fault Record.

3. If you close all open fault records and still cannot get the library into Operational condition, go to "Getting Parts and Technical Support", Check for Relevant Knowledge Articles, and, if you cannot find a resolution, Create a Service Request. Include fault codes and details of the actions that you have taken.

4. Otherwise, if desired, you can make sure that the library is functioning normally by Performing a Library Self Test.

### Step Through the Suspect Components Listed in the Fault Record

1. Note the Fault Code for the record.

2. Note the first component listed in the Suspect Components field of the record (the field may identify up to five components).

3. Note the corresponding Recommended Action.

4. If the Fault Code is 9108 and the Suspect Components field lists one or more magazines, carry out the procedure "Locate and Remove a Cartridge that is Stuck in a Magazine Slot".

5. If the Fault Code is 9108 and the Suspect Components field lists one or more drives, carry out the procedure "Free a Cartridge that is Stuck in a Drive".

6. If the Fault Code falls in the range 9102-9107 or is code 9109, an obstruction may be interfering with the robot. Carry out the procedure "Locate and Clear Obstructions, Such as Loose or Protruding Cartridges".

7. Otherwise, carry out the recommended action shown. Consult the volumes in the SL150 Modular Tape Library Customer Documentation Library for instructions. For updates and additional information, see "Getting Parts and Technical Support", and Check for Relevant Knowledge Articles.

   Be careful to carry out suggested service actions one at a time and in the order specified in the suspect components list.

   If you replace the robot, the operator panel, or the chassis of library module 1, power-cycle the library as soon as you finish. These three components maintain records of the product serial number and configuration settings. If you replace more than one of them at a time, without restarting the library, this information will be lost.

8. If the connection status indicator shows that the Library is Inoperative, you need to restart it. See "Restart the Library".

9. Once you have carried out the recommended action and, if necessary, restarted the library, see if the corresponding fault record has been closed. See "Check the Library Health Log".

10. If the Type field of the Health Log record shows that the record is still Open, you have not yet isolated the problem. Note the next item listed in the Suspect Components field of the record, and repeat steps 3-8.

11. If the Type field shows that the record is Closed and the library Health status is now Operational, stop here.

12. If the Type field shows that the record is Closed but the library Health status is still Degraded, check for remaining faults. See "Use the Health Table".

### Locate and Remove a Cartridge that is Stuck in a Magazine Slot

If the Library Health table lists an event with fault code 9108 and includes one or more magazines in the Suspect Components field for the event, a cartridge is probably stuck in a storage cell.

WARNING: Oracle's StorageTek SL150 Modular Tape Library contains a Class-1 laser, as defined by IEC 60825-1 Ed. 2 (2007). Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

To locate and correct the problem, proceed as follows:

1. Select the first magazine listed in the Suspect Components field of the fault record.

2. Take the magazine out of the enclosure. See "Manually Unlatch and Remove the Magazine".

3. Working methodically from one end to the other, grasp each cartridge by the top and bottom gripping surfaces, and see if it moves freely.

4. If a cartridge is stuck, gently try to free it, and check the source storage cell for defects.

5. If you find any damage to the magazine, request a replacement. Go to "Getting Parts and Technical Support", and Create a Service Request.

6. If you cannot free a stuck cartridge, do not force it. Go to "Getting Parts and Technical Support", and Check for Relevant Knowledge Articles. If you cannot find a resolution, Create a Service Request.

7. Otherwise, reseat the cartridge in its slot and make sure that it is moving freely.

8. Reinstall the magazine in its bay.

9. The connection status indicator now shows that the Library is Inoperative, so you need to restart. See "Restart the Library".

10. Once the library restarts, see if the corresponding fault record has been closed. Go to "Check the Library Health Log".

11. If the Type field of the Health Log record shows that the record is still Open, you have not yet isolated the problem. Repeat the procedure "Step Through the Suspect Components Listed in the Fault Record", this time investigating the next suspect component listed in the fault record.

12. If the fault record is Closed and the library Health status is now Operational, stop here. The library is again operating normally.

13. If the fault record has been closed but the library Health status is still Degraded, check for remaining, open faults. See "Use the Health Table".

### Free a Cartridge that is Stuck in a Drive

If the Library Health table lists an event with fault code 9108 and includes one or more tape drives in the Suspect Components field for the event, a tape cartridge is probably stuck in the drive. To resolve the problem, proceed as follows:

1. Note the order and identities of the components listed in the Suspect Components field of the Library Health table row that corresponds to the fault event.

2. Go to directly to "Getting Parts and Technical Support", and Check for Relevant Knowledge Articles. If you cannot find a resolution, Create a Service Request.

### Locate and Clear Obstructions, Such as Loose or Protruding Cartridges

If the Library Health table lists a fault code in the range 9102-9107 or code 9109, a mispositioned cartridge or similar obstruction is probably interfering with the robot.

WARNING: Oracle's StorageTek SL150 Modular Tape Library contains a Class-1 laser, as defined by IEC 60825-1 Ed. 2 (2007). Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

To locate and clear the obstruction, proceed as follows:

1. Select the magazine that will give you the best view of the interior of the library.

2. Manually Unlatch and Remove the Magazine.

3. If you felt any significant resistance when attempting to remove the magazine, you may have found the obstruction stop (a tape cartridge may be protruding from one of the slots in this magazine and catching on the library structure). Select a magazine on the opposite side of the library, and repeat step 2.

4. Using the empty magazine bay as a window, look inside the library and try to locate obstructions, particularly loose or protruding cartridges. Look across, above, and below.

5. If you cannot see any obstructions, gain additional visibility by removing additional magazines.

6. If you see a cartridge protruding from a storage slot in one of the magazines or lying on the bottom of the library, reach in through the open magazine bay and remove it, if you can. Provide additional clearance, if necessary, by removing additional magazines.

7. If you cannot remove the problem cartridge, stop here, go to "Getting Parts and Technical Support", and Check for Relevant Knowledge Articles. If you cannot find a resolution, Create a Service Request.

8. If you successfully removed the problem cartridge, remove the source magazine and check the source storage cell for defects.

9. If you find any damage to the source magazine, request a replacement. Go to "Getting Parts and Technical Support", and Create a Service Request.

10. Otherwise, reseat the errant cartridge in its storage cell.

11. Reinstall all removed magazines in their original bays.

12. Once you have reinserted the magazines, go to "Restart the Library". Then go to "Check the Library Health Log".

13. If the Type field of the Health Log record shows that the record is still Open, you have not yet isolated the problem. Repeat the procedure "Step Through the Suspect Components Listed in the Fault Record", this time investigating the next suspect component listed in the fault record.

14. If the fault record has been closed and the library Health status is now Operational, stop here.

15. If the fault record has been closed but the library Health status is still Degraded, check for remaining open faults. See "Use the Health Table".

### Manually Unlatch and Remove the Magazine

To release the automatic magazine latches during troubleshooting, manually override the software-controlled latches using the following procedure.

Caution: Use this procedure only during specified installation, maintenance, and troubleshooting procedures or under the direction of an Oracle service representative. Do not routinely override the automated magazine latches. To release a magazine during normal operation, use the user interface software: see "Unlatch the Magazine".

1. If the library is online, carry out the steps under "Take the Library Off Line" before proceeding further.

2. Insert a 1/64-in Allen wrench into the hole at the lower inside corner of the cartridge magazine (a large paperclip that has been straightened into an L shape will do in an emergency).

3. Align the Allen wrench parallel to the magazine face and slowly push it into the hole.

4. Grasp the handle on the front of the magazine and slowly and gently pull the magazine a short distance out of the library. Stop if you feel any resistance other than the usual slight friction.

5. Remove the wrench.

6. Support the bottom of the magazine with your other hand.

7. Slowly and gently start to pull the magazine free of the module.

8. If you feel any significant resistance, stop immediately, particularly if you are looking for an obstruction (a tape cartridge may be protruding from one of the slots in this magazine and catching on the library structure).

9. If the magazine slides freely, draw it out of the library, handling it carefully so that cartridges do not spill out.

10. Set the magazine aside on a flat, stable, uncluttered surface, and make a note of the module that you removed it from.

11. Return to what you were doing, either "Locate and Remove a Cartridge that is Stuck in a Magazine Slot" or "Locate and Clear Obstructions, Such as Loose or Protruding Cartridges".

### Restart the Library

In a troubleshooting situation, you may have to restart the library more than once. Proceed as follows:

1. In the remote user interface, click on the power-button icon—a circle broken by a vertical bar at upper left.

2. When the context menu appears, select Restart Library.

3. Return to what you were doing:

   - "Locate and Remove a Cartridge that is Stuck in a Magazine Slot"

   - "Locate and Clear Obstructions, Such as Loose or Protruding Cartridges".

   - "Step Through the Suspect Components Listed in the Fault Record".

### Check the Library Health Log

1. Select Service from the menu on the left side of the browser-based user interface, and select the Health Log tab from the tabbed property sheet on the screen.

2. In the Health Log table, locate the row for the fault that you have been working on.

3. Note the value of the Type field.

4. Return to what you were doing:

   - "Locate and Remove a Cartridge that is Stuck in a Magazine Slot"

   - "Locate and Clear Obstructions, Such as Loose or Protruding Cartridges"

   - "Step Through the Suspect Components Listed in the Fault Record".

### Performing a Library Self Test

The library has a self-test feature that exercises all of the library's capabilities and can thus assist with fault isolation, validation of repair actions, and re-calibration following repairs or reconfiguration. A Basic Self Test performs the following tasks:

- It fetches a diagnostic tape cartridge and moves it to every empty mailslot cell and free drive in the library.

- It fetches and returns data tapes that occupy mailslot cells and drives.

A Full Self Test expands on the basic test:

- It fetches a diagnostic tape cartridge and moves it to every empty storage slot, empty mailslot cell, and free drive in the library.

- It fetches and returns all data tapes that occupy storage slots, mailslot cells, and drives.

- It recalibrates the library robot.

Note that a full test can take some time, depending on the number of modules in the library. So plan accordingly.

To carry out a self test, proceed as follows:

#### Run a Library Self Test

1. If you have not already done so, take the library offline. See "Take the Library Off Line".

2. Make sure that you have a diagnostic cartridge stored in a reserved system slot or in the mailslot.

   For further information, see "Loading and Unloading Individual Cartridges", "Reserving Storage Slots for System Use", and "Providing Diagnostic Cartridges".

3. Click the Library control at the top left of the Library screen.

   The graphical library map appears.

4. Make sure that the mailslot is closed.

5. Make sure that all magazines are securely latched.

6. Make sure that at least one operational drive is free.

7. Make sure that there is at least one unoccupied cell in the mailslot.

8. Click the Library control at the top left of the Library screen.

9. Select Run Self Test from the Library control's context menu.

10. Select Basic Self Test or Full Self Test from the menu. A basic test will take a few minutes. A full test will take considerably longer.

11. To run the specified test, press OK when the confirmation bar appears at the top of the screen. When the test completes, the result bar will display the number of moves performed. Press OK to close the result bar.

12. To skip the test press Cancel.

13. To end a running test prematurely, press the Stop the Test button that appears after the test starts. It may take a short while for the test to stop. When it does, press OK.

14. If the diagnostic cartridge was not returned to its reserved cell at the end of the test, move the diagnostic cartridge now. See "Move Tape Cartridges Using the Browser-Based User Interface".

### Saving the Health Log to a File

If you need to work on diagnostics off-line or if you need to open a service request, save the contents of the system health log to a file. Proceed as follows:

#### Export the Health Log

1. Log in to the browser-based user interface under the Administrator or Service role.
