FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
   PROBLEM OVERVIEW: How to Remove/Replace a Tape Drive CRU in the StorageTek SL150 Modular Tape Library
   WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: The SL150 library should be put into an offline state from the Web GUI.
   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

To Remove the Tape Drive:

Note – The bridging tape drive is located in the top drive slot of the base module. The robot control is a SCSI Medium Changer device that appears as LUN 1 on a bridging tape drive. If the library is partitioned, there must be two tape drives in the base module, and each tape drive provides the robot control for its assigned partition.  If the failed drive is the bridging drive then the SL150 library must be taken offline to the host as replacing the tape drive will cause the host to lose connectivity to the SL150 library.  If the tape drive is not a bridging drive then it can be hot swapped.

1.Quiesce activity for this tape drive.

2.Log into the SL150 remote interface using your browser.
3.(Optional) Enable the locate library indicator.
4.Prepare the tape drive for removal:
   a.Click Library on the left of the remote interface.
   b.Move the cursor to the drive you need to replace.
   c.Click the drive icon and select Remove Drive.
   d.Click OK in the confirmation dialog box.  The physical LED at the rear of the drive tray lights to indicate the drive is ready for removal.

5.Remove the tape drive:
   a.Access the back of the library (open the rear door of the rack, if applicable).
   b.Locate the tape drive with the blue LED (indicates drive is ready for removal).
   c.Verify that the interface cables are labeled. Attach a label if necessary.
   d.Disconnect the cables from the jacks on the left side of the drive tray.
   e.Loosen the captive thumbscrews on the drive tray (see FIGURE 3-9).
   f.Grasp the drive tray, pull it out of the library drive slot, and set it upright and flat on a static free surface.

To Replace the Drive Tray:

Caution – ESD damage. Do not touch any electronic components or contacts.

1.Remove the replacement drive from its packaging.
2.Replace the tape drive:
   a.Grasp the rear corners of the drive tray.
   b.Guide the front of the drive tray into the module drive slot.
   c.Push the drive tray completely into the drive slot.
   d.Verify that the LEDs are active on the rear of the drive tray.
   e.Tighten the captive thumbscrews firmly on each side of the drive tray to make sure there is no tray movement in any direction.

3.Push the Locate indicator on the robot CRU to extinguish the light, if applicable.
4.Confirm that the library recognizes and accounts for the drive from the Web GUI or front Op Panel.

Note – Identify the tape drive firmware version (see Appendix B, “Drive Firmware”). You might need to load a firmware version that is consistent with other installed tape drives.

5.Make sure the drive port is enabled (view the Drive Properties and change drive settings if appropriate).
6.Connect the interface and Ethernet cables to the proper jack on the left side of the drive tray.
7.Log out of the SL150 remote interface or return the touch screen to Home.

OBTAIN CUSTOMER ACCEPTANCE
   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?: The SL150 library will need to be brought to an online state from the Web GUI.
