Remove and Replace a Drive

Overview

Tape drives are installed in the back of the library. The i6 supports up to three IBM Fibre Channel (FC) LTO-6 and later drives or three IBM LTO-9 SAS full-height drives per 6U chassis. You can connect from the Fibre Channel ports directly to the server or to a storage area network using a Fibre Channel switch or directly connect SAS to an HBA. You must use a cover plate to cover any empty tape drive slot.

Before You Begin

Important Information - Drive Acclimation

Before opening the sealed ESD bag, the drive should be acclimated to the climate inside the facility or room location where the drive will be installed. Changes in temperature and humidity can cause condensation. It is recommended to leave drives in the packaging for a minimum of 24 hours before opening the sealed bag.

Place the sealed bag away from direct sources of air convection to minimize condensation.

If any external or internal condensation is seen on the sealed bag after 24 hours, remove the drive from the bag and acclimate the drive in the planned location for an extra 12 to 24 hours, or until no visible condensation remains.

Figure 1: Drive in Sealed Bag

Once the bag has been opened, the drive should never be moved to a new location where temperature differences are greater than 5 degrees Celsius. If this type of drive relocation needs to occur, the drive should be placed in a sealed bag with desiccant and allowed to acclimate to the new location for a minimum of four hours.

Before you begin the removal procedure, take a snapshot of the library and save your library configuration. These will be used to restore your library if any issues occur after the removal and replacement procedure.

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 a Drive

Important Information - Before You Begin

Before you begin a drive removal, review the following information.

This video shows the drive replacement procedure for a Scalar i6. The overall procedure is the same for the Scalar i3. However, the Scalar i3 supports either Fibre Channel or SAS connectivity whereas the video shows Fibre Channel. In addition, the Scalar i3 supports half-height drives whereas the video shows full-height drives.

Before removing a drive, check to see that it doesn't contain a tape. You can perform this check visually by looking in the window of the library. Or, you can use the WebGUI to verify that the drive does not contain a tape.

Drives can be visually inspected for tapes by looking in the front window of the module.

In the WebGUi, go to Library > Drives. A tape in a drive will be indicated under the Media column.

  1. From the Navigation panel, select Drives.
  2. In the North Panel, select the check box next to the drive(s) you want to eject media from.

  3. In the Operations panel, click Eject.

  4. Click Apply to save your settings.

  5. Click Close to exit the window.

Note: If you experience a stuck tape while trying to eject the tape, vary the drive off and on. When it is back to ready, select the drive and click Eject. If the tape remains stuck, continue to Step 2 below.

  1. From the Navigation panel, select Drives.
  2. Select a drive from the North Panel by clicking the checkbox next to it.
  3. Click the Remove/Vary-Off button. The drive state will display as Varied Off after the operation is complete.

  1. Identify the drive that was varied off. All drive state LEDs on the back of the drive should be off.

  2. Disconnect the Fibre or SAS cable from the drive. The example below is a Fibre Channel drive.

  3. Loosen the drive thumbscrew.

  4. On the left side of the drive sled, press the lock lever up and slide the drive out of the drive bay.

Note: If you removed a drive that contained a stuck tape, contact Quantum Service and Support for further assistance. In addition, you should also clear any RAS tickets in the library related to the stuck tape in the drive.
