HP B-series Fabric OS 6.3.2e Release Notes (5697-1816, March 2012) - includes all 6.3.2x versions

• Both ends of a tunnel must be identically configured for the Compression, FastWrite, and Tape

Pipeline options. If a mismatch exists, the tunnel will not be established and the TCP virtual

connections will be removed.

• Under traffic isolation (TI) zone configurations with failover enabled, non-TI zone traffic will

use the dedicated path if no other E or VE paths through the fabric exist, or if the nondedicated

paths are not the shortest paths. (A higher bandwidth tunnel with multiple circuits will become

the shortest path compared to a single tunnel.)

• A VE/VEX tunnel and E/EX FC port cannot connect to the same domain at the same time.

• The recommended Keep Alive Timeout must be the same on the tunnel and circuits on the

switches on both sides of a link.

• Latency measurements supported on FCIP tunnels (tested limit under Fabric OS 6.3.2):

1 GbE with 200 ms round-trip time and 1% loss◦

◦ 10 GbE with 50 ms round-trip time and 0.1% loss

• The 1606 Extension SAN Switch supports optical and copper media types on GE0 and GE1

interfaces. Copper media is the default on GE0/GE1 ports and does not support autosense

functions.

• Inserting a 4 Gb SFP in GE ports of an HP 1606 Extension SAN Switch or DC SAN Director

Multiprotocol Extension Blade, can occasionally return one of the following messages:

◦ No_Light or Unknown for GE ports in switchshow output.

Remove and reinsert the optic cable to correct this indication.

◦ Can't read serial data in sfpshow output.

Reissue the sfpshow command to resolve this issue.

FCoE/CEE (2408 FCoE Converged Network Switch and DC SAN Director Switch

10/24 FCoE Blade)

• Configupload and configdownload operations attempted on the 2408 FCoE Converged

Network Switch fail with an error message if that switch does not have an FCoE license

installed and is running a firmware version earlier than Fabric OS 6.4.0c.

• The 2408 FCoE Converged Network Switch balances the FCoE bandwidth across all six port

groups (each port group contains four ports). To get optimum performance for FCoE traffic

HP recommends that the user distribute server CNA connections across these six port groups.

• Hot-plugging a CP with a firmware level earlier than Fabric OS 6.3.0 into a DC SAN Backbone

Director or DC04 SAN Director with an active DC SAN Director Switch 10/24 FCoE Blade

will result in the new standby CP not being HA synchronized. To avoid this scenario, upgrade

the code on the standby CP directly to match the version on the active CP.

• HP recommends that Converged Mode be enabled on all interfaces connected to CNAs.

• When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface

is processed normally. The host should be configured not to send VLAN tagged traffic on the

switch’s native VLAN.

• The CNA may lose connectivity to the 2408 FCoE Converged Network Switch/DC SAN

Director Switch 10/24 FCoE Blade if the CNA interface is toggled repeatedly over time. This

issue is related to the CNA; rebooting the CNA restores connectivity.

• Although the 2408 FCoE Converged Network Switch/DC SAN Director Switch 10/24 FCoE

Blade support the configuration of multiple CEE maps, HP recommends that you use only one

CEE map on all interfaces connected to CNAs. Additionally, CEE maps are not recommended

for use with non-FCoE traffic. QoS commands are for interfaces carrying non-FCoE traffic.
