Setting Drive Id - Tandberg Data StorageLibrary T40+ Series Installation And User Manual

The library is automatically taken offline when the unit is busy executing internal time consuming
tasks.
In addition, the user can manually take the physical library, or any of its partitions, online or offline.
You can take a partition offline rather than the entire library so as to minimize disruption of library
operations. You may manually change the partition mode to online or offline from the front panel or
from the remote management interface.
Details on changing partition mode include:
The default partition mode is online.
The partition mode must be set to Offline if you want to restrict host access to the specified
partition.
When you are changing partition mode, be aware of the following information:
The Online/Offline buttons toggle between states.
It is only possible to set a partition offline when the partition is not in use.
Set the button to read Online to take either the physical library or a partition (depending on the
current view) to an online state. This is the normal operating condition. In this mode, robotics is
enabled and all host commands are processed.
Set the button to read Offline to take either the physical library or a partition (depending on the
current view) to an offline state. If only the physical library is taken offline, the library's partitions
will not process robotics commands, even though they are online. If only a partition is taken
offline, neither the physical library nor the other partitions will be affected
The paths to open the appropriate screens are:
From the RMI, select Operations > Partition Mode
From the FPI, select Menu > Operations > Change Partition Mode

Setting Drive ID

A SCSI ID is a value between 0–15. Each device on a SCSI bus (including the HBA) needs to have a
unique ID. Changing the SCSI ID is necessary when there is a duplicate ID on a single bus. Typically,
the HBA SCSI ID is set to 7. For example, if two tape drives are connected together on the same bus,
each tape drive must have different SCSI IDs and they must be different from the HBA SCSI ID.
The library assigns default SCSI IDs to SCSI tape drives. The SCSI ID for drives is based on the bay
position in the library, and not the drive itself. This means that if a drive is replaced, or moved to a
different bay, the drive will take on the SCSI ID of the bay that it is installed in. The Set Drive ID
feature allows the operator to change the SCSI ID for any drive position. The default SCSI ID for the
drive bays is defined as follows:
Default
Drive Bay

1 (bottom)

4 (top)
The drive SCSI ID is configured with the Setup Wizard. After the initial setup of your library you can
later access the SCSI ID configuration screens directly:
From the RMI, select Setup > Partitions
From the FPI, select Menu > Setup > Partition
