IPv6 Network Address Support
The dual-stack network configuration supports both IPv4 and IPv6.
Library firmware versions 2.0 and later support a dual-stack network configuration that
uses both IPv4 and IPv6. In dual-stack mode, the library continues to recognize IPv4
addresses while adding the use of IPv6 addresses. To configure the network address,
see
Configure the Network Interfaces
. Always consult with the network administrator
before configuring or changing IPv6 addressing and to get the length of the network
prefix for your location.
Selecting a Switch that Uses Power Over Ethernet (POE)
Network switches providing power over Ethernet (POE) must be IEEE certified.
When selecting a POE switch, make sure that it is IEEE certified. A switch that is
not IEEE certified might provide too much current over the cable and overload the
Ethernet connection on the library. Results of an overload appear as the Ethernet port
being unresponsive and the remote management interface not working.
Configuring a SAN Connection
You can connect the library to the host HBA through a storage area network (SAN).
Configure zoning on the FC switch so only the backup servers access the library.
Zoning
Use zoning to partition a SAN into logical groupings of devices so that each group is
isolated from the other and can only access the devices in its own group. Two types
of zoning exist: Hardware zoning (based on physical fabric port number) and Software
zoning (defined with the World Wide Node Name (WWNN) or World Wide Port Name
(WWPN)).
The dynamic World Wide Name (dWWN) feature assigns world wide names to the
library drive slots rather than the drives themselves, which allows you to swap or
replace a drive without bringing down the entire operating system.
Persistent Binding
When a server is started, it discovers attached devices and assigns SCSI target and
LUN IDs. It is possible for these SCSI assignments to change between restarts. Some
operating systems do not guarantee that devices will always be allocated the same
SCSI target ID after restarting. Also, some software depends on this association, so
you do not want it to change.
