Table 7 Libraries parameters (top half of page)
Description Parameter
Identifies the selected device (library). HP recommends usnig a name that identifies the
host or backup job with which it is associated. Name
The role of the library, which may be non-replicating, replication source or replication
target. Replication Role
The status of the library, which may be online, offline, notstarted, failed to start, stopping,
creating, or deleting. Status
Indicates whether the library is connected. Possible values are: Connected – A client
device is connected to any device (robotics or drive) within this library. Not Connected
– No device is connected to this library. Connection
The emulation type used by the backup software. It is selected when you create a device. Device Type
The number of cartridges or slots available on the device, which is determined by the
Emulation types for tape device selected when the device was created. You can reduce
Cartridges / Slots
the number of slots in the Device Details tab for a library selected on this page, but this
will only remove the highest empty slots. Once it reaches a slot number that contains
data, it will not allow you to reduce the number further on this page, even if earlier slots
are blank. You must first use the Cartridges tab to make the slot empty.
Identifies the port to which the host is connected for backup and restore. The number of
ports available in the drop-down menu depends upon the interfaces that your model
supports and your network configuration.
There are four Fibre Channel ports available. When creating a library you may select
individual drives or Fibre Channel ports 1&2 or Fibre Channel ports 3&4. Port
