Configuring the Library
Set the button to read Offline to take either the physical library or a partition, depending on the
current view, to an offlin
e state. If only the physical library is taken offline, the librarys partitions
will not process robotics commands, even though they are online. If only a partition is taken
offline, neither the physical library nor th
e other partitions are affected
.
The
paths to open the appropriate screens are:
From the
RMI
, select
Operations > Partition Mode
From the
FPI
, select
Operations > Change P
artition Mode
Setting Drive ID
A SCSI ID is a value between 0
15. Each device on a SCSI bus (including the HBA) needs to h
ave 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 an
d 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 replac
ed, or moved to a
dif
ferent 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
bay
s is
defined
as follows:
Drive Bay
= 1 (bottom
)
Drive Bay
= 2
Drive Bay
= 3
Drive Bay
= 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 >
Partition/drive
From
the
FPI
, select
Setup >
Partitions
If your library includes fiber c
hannel tape drives the Setup Drive ID screen shows the
world wide
node
name
and port name of the
fiber ch
annel drive.
These are not configurable.
The world wide node name and port name
f
or 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 node name and port name of the
bay
that it is installed in.
The node names and
port names are unique for each library and are assigned to the library during
manufacturing.
Modifying the Control Path
The control path tape drive is used to connect a partition to a host application.
For normal operation
o
nly one tape drive
should
be sel
ected as the control path
for each partition
at one time. By default,
the lowest tape drive assigned to a partition is designated the control path. In the event that the
control path connection to the host application fails, you can manually select a new c
ontrol path for
the partition.
Note
You may need to modify settings in your host application as a result of modifying
the control path. For details, refer to your host application documentation.
