library using a configuration file that was saved with the same version of
firmware currently installed in the library.
Since the RMU can be accessed remotely, its implementation will save/restore the
configuration data to/from a file on the host site. When entering commands on the
OCP, the unit is accessed directly. For this reason the OCP implementation will
save/restore the configuration data to/from a USB memory stick that is inserted
into the USB connector on the library controller.
Note: Factory defaults must be restored when the library drive is changed from a
LTO half height to full height configuration, in order for the library to
correct the element addressing and drive numbering. If a new drive is
added to the library configuration, a restore factory default is not required.
Service Library Menu
Some Service Library functions will post a warning message stating that the library
should be taken offline from the host before performing any Service functions. It is
up to the operator to ensure that it is taken offline at the host. Before performing
any service functions, ensure the host is not performing any data writing or
retrieval.
Service Library: Clean Drive
If the library is not configured for Auto Clean, this page allows the user to
manually clean the tape drive.
A drive cleaning is initiated only after the library or drive posted a status message
that indicates Cleaning Required
To manually complete a drive cleaning, complete the following steps:
1.
Select a cleaning cartridge that is listed in the Slot # field.
2. Select a drive that is listed in the Drive field.
3. Click Clean. See Figure 5-53 on page 5-59.
Note: Enabling the Auto Clean function is recommended on the library. With the
Auto Clean function enabled, drive cleaning occurs automatically. The only
time Auto Cleaning is disabled is when your Backup Application requires
that it has control.
Drives that do not require a cleaning are labeled with No Cleaning Required. See
Figure 5-51 on page 5-59.
