Replace a Control Module (CM) Chassis

This procedure replaces an existing Control Module (CM) chassis with a new CM chassis.

Before You Begin

Before you begin the removal procedure, take a snapshot of the library and save your library configuration.

Your library has many configurable items, such as tape drive IDs, partitions, user accounts, Import/Export (I/E) slots, and cleaning slots. The Save/Restore window allows you to save your library's configuration and then restore the library’s firmware and configurable items to a previous state in the event of a hardware failure or firmware upgrade.

Restore a Configuration on the same Library

Before you restore a library configuration, review the following:

  • If you have Logical System Addressing (LSA) enabled on the library, the saved configuration is specific to that library only. Do not attempt to clone the configuration to a different library.
  • The library must have all the proper licenses installed before restoring a configuration.

Restore a Configuration on a new Library

Before you restore a library configuration, review the following:

  • If you have LSA enabled and want to clone the configuration to a new library, you must first disable LSA and save the configuration (see Library Settings).
  • If you want to clone a saved configuration to another library, you should only use the saved configuration upon initial installation of a new library. Once a the cloned configuration is on a new library, you should save a configuration specific to that new library.
  • If you are cloning a saved configuration to a new library, the new library must have the same minimum license configuration as the library where the saved configuration came from.
  • If you are cloning a saved configuration to a new library, the new library must have at least the same minimum module configuration. For example, if the library the saved configuration came from has 4 modules, the new library must have a least 4 or more modules.

The Library Snapshot feature captures detailed information about the entire library in a single ASCII file that can be e-mailed to technical support personnel. The information consists of configuration data, status information, and trace logs for library components. Trace logs collect problem data and provide support personnel with vital library information for troubleshooting and solving problems.

You can e-mail the snapshot file from the WebGUI. You can also download the snapshot file to your computer. However, you cannot print snapshot files directly from the Web client. Depending on the library configuration and your connection speed, saving the snapshot file could take several minutes. The resulting file size can be large. In some cases, your firewall file-size limitations could prohibit you from emailing the file.

Remove the Control Module (CM) Chassis

Before you remove the robot, you must correctly position it in the system. Use on of the following methods below to position the robot.

Note: Positioning the robot will cause it to vary off.

  1. Select Devices.
  2. From the North Panel, click the + next to Robotics. Select the checkbox for the Robot.

  3. In the Operations Panel, click Position. The Position window displays.

  4. Select the Replace radio button.
  5. Click Apply. This positions the robot in the module that is second down from the top in the library stack.

You can now perform the remainder of the Remove Robot procedure. In some rack configurations you might not be able to take the top cover off. In these cases you must remove the top module by following the Remove Module procedure.

If you are not using the WebGUI to position the robot, you will have to use the LUI. To do this, use the following path:

Service Functions > Maintenance > Robot Position > Replace

Some robot malfunctions prevent he robot from being positioned using the WebGUI. In these situations, you must position the robot by hand.

  1. Mark and remove the magazines. Mark each magazine so you know which bay it came from. Magazines must be placed back in the bays they came from.

  2. Mark and disconnect the cables from the tape drives.
  3. Mark the drives so you can replace them in their locations. Remove the drives.
  4. Remove any remaining drive covers.
  5. Identify the module where the robot is positioned. Insert your arm into the empty magazine well of the module and push up on the bottom front of the robot.
  6. Push up on the bottom rear of the robot until it is level with the front. You may have to go around to the back and reach through the drive bays to do this if your arm is not long enough, or is too big around to reach the bottom rear through the magazine well.
  7. Continue this pushing up procedure until you’ve positioned the robot in the module second from the top.

There are two (2) ways for you to power off your library:

Select Shut Down from the admin menu on the Menu Bar.

Navigate to Power > Shutdown

Mark all magazines, drives, cables and modules in someway so you can return everything where it belongs in all modules above the CM as well as the CM itself.

  1. Insert the T8 end of the assembly tool into the magazine release hole until the magazine pops out. Remove the magazine.

  1. Disconnect the power cables from the power source.
  2. Disconnect the power cables from the power supplies.
  3. Disconnect the Ethernet cable.
  4. Disconnect the SAS or Fibre channel cables from the drives

  1. Pull out on the pin and slide the module interconnect down.

Depending on how many modules you need to remove, start at the top most module in the rack and remove the attachment screws.

There are two different versions of the chassis available on Scalar i6 systems: Series 1 and Series 2.

Identify Your Chassis Series

  • Series 1 - A Series 1 chassis uses screws to attach modules together.
  • Series 2 - A Series 2 chassis contains latches on the front and rear of the chassis. These latches are used to attach modules together. A Series 2 chassis is backwards compatible with the Series 1 chassis.

Select from the options below:

  1. Remove the two (2) long screws in the holes at the front of the module in the magazine bays using the Torx tool.

  2. Place the screws aside.

  3. Remove the two (2) short screws in the holes at the back of the module in the drive bay using the torque wrench.

  4. Place screws aside.
  1. If magazines are in the chassis, remove the magazines to access the front and rear latches in the chassis.

  4. Set the clamps aside.

Using two (2) people, slide the module out of the rack and set on a flat surface.

  1. If the CM was located at the top of the library stack, remove the top cover. If the CM was not located at the top of the stack and you had to remove EMs, go to step 2.

    There are two different versions of the top cover available on Scalar i6 systems, one with screws and one without screws.

    Select from the options below:

    1. If you did not remove the magazines while unpacking the library, do so at this time.

    2. Using the empty magazine slots for access, use both hands to gently push up and forward on the inside of the top cover. This will release the top catch and side stops.

    3. Slide the top cover off.

    Required Tools: T-10 Torx Driver (included with library assembly tool)

    1. Use the assembly tool to remove the 8 cover screws.

    2. Remove cover. Be careful not to let the cover sag in the middle or at the ends.

  3. Remove all plastic covering.
  4. Remove drive bay covers from the back of the module.

  1. Place the module on top of the previously placed module.

  1. Insert the “ear” of the rack mount clamp in one of the three slots on the side of the library. Choose the slot based on how much of the library you want to extend beyond the front and back of the rack. If your rack has a door, you want to make sure you can close the door when the library is mounted in the rack.

  2. Screw the 4 thumbscrews through the rack mount clamp slots into the threaded holes in the rack shelves.

Additional Information

  • If you are adding the module to another module, don’t tighten the thumbscrews until you’ve aligned and attached the module. When the two alignment pins are down and the four module attachment screws have been tightened, tighten the rack thumbscrews.
  • Due to i6 modules being slightly smaller than 6U, in large systems the rack mount claps will eventually stop aligning to the rack and cannot be used. In a full 48U i6 configuration, the top of the rack can be off by approximately .5U. Do not attempt to force align the rack mount clamps.

IVT is a diagnostic test that verifies basic library functionality. It performs a complete library installation test to verify robotic operation within the current library configuration. IVT tests determine proper installation and operation by performing robotic self tests, by scanning tape cartridges, and performing GET/PUT tape cartridge tests at storage slot, I/E slot, and drive sled locations.

IVT uses existing tape cartridges for in-place GET/PUT testing, and moves a scratch tape to empty locations to verify proper slot and/or drive sled accessibility.

A complete IVT should be run as part of the installation process.

IVT Prerequisites

Review the following before running an IVT test:

  • The library should have no unresolved RAS tickets.
  • The library WebGUI accurately reflects the actual number of modules and drives in the system.
  • The library is in a READY state all magazines are properly inserted.
  • A scratch tape must be provided and placed into the first slot of the configured I/E area (Control Module's top right magazine, first column, bottom slot). If an I/E area is not configured, this slot position will be used by the library to locate the scratch tape, even if this slot is assigned as a storage slot to a partition.

  • Do Not use any cleaning tape as an IVT scratch tape. The IVT may fail due to timeout conditions.

  • Do Not use an uncalibrated LTO-9 tape as an IVT scratch tape. If you do, the test will immediately fail and the drive will continue to calibrate the tape until it is complete. You will then need to manually remove the (now calibrated) tape and re-run IVT.
  • If you do not have a calibrated LTO-9 scratch tape to run IVT, vary off the LTO-9 drives (see Vary Drive On or Off). This will prevent the test from failing due to LTO-9 calibration operations.

In addition to the prerequisites above, Quantum recommends that the scratch tape is read-capable by all drive generations in the library. If the tape cartridge media generation is not supported by a drive generation in the library, drive tests are skipped. The skipped drive tests will then need to be repeated with a scratch tape of compatible read format.

  1. Press the right magazine release button on the Control Module (CM). The magazine will “pop” out. Pull the magazine until the first set of slots is exposed.

  2. Insert a scratch tape. A scratch tape is a blank tape or one you don’t mind being overwritten. Insert the tape into the bottom front slot in the right magazine. This is the designated I/E slot for the library.

  3. Select Diagnostics from the WebGUI menu.

  4. Select the Installation Verification Test checkbox from the North Panel.

  5. Click the Test button in the Operation Panel. The Installation Verification Test window displays.

  6. The Complete IVT radio button should be pre-selected. If it’s not, select it.

  7. Click Apply. The Progress area of the dialog window will display the test progress.

    Note: You must wait until the library has finished initialization before you can begin the IVT process.

  8. The results of each of the IVT tests displays in the Progress area.

    Caution: The library will display a Ready status during IVT. Disregard and do not try and perform any library operations. When each Magazine Test is complete, the library will be ready.
