Relaxing subnet restrictions Beginning with Fabric OS 7.0.0a, subnet restrictions have been lifted. On HP DC SAN Director Multiprotocol Extension Blade and HP 1606 SAN Extension Switch running pre-Fabric OS 7.0.0a, there was restriction where each IPv4 Gigabit Ethernet interface must have had IP addresses on a separate subnet from all other interfaces and IPv6 addresses must be on separate prefixes from all other interfaces. In addition, the IPv6 interfaces must have had a unique link-local address from the peer node on that interface. GigE/xGigE port sharing across Logical Switches On HP DC SAN Director Multiprotocol Extension Blade running pre-Fabric OS 7.0.0a, to create a tunnel in a Logical Switch (LS), both the VE_Port and the corresponding GE_Port must be in the same LS. Starting with Fabric OS 7.0.0a, this limitation is removed. That is, VE ports in different LSs are able to share a GE_Port/xGE_Port that is present in the Default Switch. Increase in number of circuits on 1 GE ports In Fabric OS 7.0.0a, the number of circuits supported per tunnel on 1 GE ports has been increased as follows: • Up to 6 circuits per tunnel on HP 1606 SAN Extension Switch • Up to 10 circuits per tunnel on HP DC SAN Director Multiprotocol Extension Blade Encryption Platform Enhancements (HP StorageWorks Encryption SAN Switch / HP StorageWorks DC Switch Encryption FC Blade) Fabric OS 7.0.0a includes support for the key vault diagnostics. The key vault connectivity information is periodically collected and any connectivity errors are reported as RASlog. Access Gateway Enhancements Detection of Unreliable N_Port Links This feature monitors the reliability of a link on every N_Port of an Access Gateway. If the number of ONLINE/OFFLINE SCNs (State Change Notifications) for a port exceeds a certain threshold within a predefined time period, the link is considered unreliable and failback is disabled for that port. Once the port is reliable again, user configured failback settings are enforced. The port becomes reliable when the number of SCNs is less than the threshold value in the most recent time interval. RADIUS/LDAP support Starting with Fabric OS 7.0.0a, RADIUS/Active Directory for user management is supported on the switches operating in AG mode. HP B-series Fabric OS 7.0.0a Release Notes 9

Relaxing subnet restrictions
Beginning with Fabric OS 7.0.0a, subnet restrictions have been lifted. On HP DC SAN Director
Multiprotocol Extension Blade and HP 1606 SAN Extension Switch running pre-Fabric OS 7.0.0a,
there was restriction where each IPv4 Gigabit Ethernet interface must have had IP addresses on a
separate subnet from all other interfaces and IPv6 addresses must be on separate prefixes from all
other interfaces. In addition, the IPv6 interfaces must have had a unique link-local address from the
peer node on that interface.
GigE/xGigE port sharing across Logical Switches
On HP DC SAN Director Multiprotocol Extension Blade running pre-Fabric OS 7.0.0a, to create a
tunnel in a Logical Switch (LS), both the VE_Port and the corresponding GE_Port must be in the same
LS. Starting with Fabric OS 7.0.0a, this limitation is removed. That is, VE ports in different LSs are
able to share a GE_Port/xGE_Port that is present in the Default Switch.
Increase in number of circuits on 1 GE ports
In Fabric OS 7.0.0a, the number of circuits supported per tunnel on 1 GE ports has been increased
as follows:
•
Up to 6 circuits per tunnel on HP 1606 SAN Extension Switch
•
Up to 10 circuits per tunnel on HP DC SAN Director Multiprotocol Extension Blade
Encryption Platform Enhancements (HP StorageWorks Encryption SAN Switch
/ HP StorageWorks DC Switch Encryption FC Blade)
Fabric OS 7.0.0a includes support for the key vault diagnostics. The key vault connectivity information
is periodically collected and any connectivity errors are reported as RASlog.
Access Gateway Enhancements
Detection of Unreliable N_Port Links
This feature monitors the reliability of a link on every N_Port of an Access Gateway. If the number of
ONLINE/OFFLINE SCNs (State Change Notifications) for a port exceeds a certain threshold within
a predefined time period, the link is considered unreliable and failback is disabled for that port. Once
the port is reliable again, user configured failback settings are enforced. The port becomes reliable
when the number of SCNs is less than the threshold value in the most recent time interval.
RADIUS/LDAP support
Starting with Fabric OS 7.0.0a, RADIUS/Active Directory for user management is supported on the
switches operating in AG mode.
