Turn Off the Library

Turn off the library to completely power down the system.

1. Stop any host activity. Ensure all library requests have completed.
2. Click the power button in the upper left of the GUI.

   Note:

   Powering down the library will interrupt all host jobs. If you shut off power to the library without performing the following procedure, you risk possible equipment damage, tape damage, and loss of data.
3. Select Power Down Library.
4. Optionally, select settings "Bypass audit" or "Probe for configuration" when the library turns on.

   Note:

   You must select "Probe for configuration changes" if you plan to add or remove modules, drive arrays, or CAPs.

   • Bypass audit if door opened with power off – Normally, if a door opens while the library is off, the library will run a full audit when it resumes operation. However, if you plan to enter the library while it is off, but will not move any tape cartridges, then you can enable this option to bypass the full audit. This is also known as "suppress HBO" (suppress Has Been Opened). Only select this option if you are not going to add, remove, or move any tapes or drive trays.
   • Probe for physical configuration changes upon next restart - The robot will scan the module identification blocks during startup and perform a full audit. You must select this option when modifying the physical configuration. The probe only occurs on the initial restart after you select this option. Then, this option resets, so that subsequent restarts will not probe for configuration changes.
5. Click Power Down. The library operator panel will go black once the power down sequence completes.
6. Turn off the breaker on all PDUs at the bottom-rear of the Base and Drive Modules.
