only in OUIs. The merge logic would drop one of the login groups to satisfy the requirement to keep the login group name unique in the fabric-wide configuration. • Ethernet switch services must be explicitly enabled using the command fosconfig -enable ethsw before powering on a DC SAN Director Switch 10/24 FCoE Blade. Failure to do so causes the blade to be faulted (fault 9). • To support nondisruptive firmware upgrades on the DC SAN Backbone Director/DC04 SAN Director, a new service, ethsw, is being introduced to enable Ethernet switching on the DC SAN Director Switch 10/24 FCoE Blade in Fabric OS 6.3. LAN switching is disabled by default in Fabric OS 6.3. The user must explicitly enable Ethernet switch service using the command fosconfig -enable ethsw to prevent FC traffic interruption. • Upgrading DC SAN Backbone Director/DC04 SAN Director with DC SAN Director 10/24 FCoE blade from Fabric OS 6.x to 6.3 is nondisruptive. You can enable ethsw after upgrading without interrupting FC traffic. Upgrading firmware on the 2408 FCoE Converged Network Switch disrupts the FC traffic. • For HP StorageWorks DC SAN or DC04 SAN Directors with one or more SAN Director Switch 10/24 FCoE blades installed, downgrading or upgrading the Fabric OS 6.3 firmware to another version disrupts traffic through the blades. HA Failover of CP blades in either of these directors disrupts traffic through the 10/24 FCoE blades. • Upgrades from Fabric OS 6.3 to future releases will be nondisruptive to data traffic and will have behavior similar to a CP failover; ethsw remains unchanged. • Downgrade from Fabric OS 6.3 to 6.1.2_cee1 is disruptive if ethsw is enabled on Fabric OS 6.3. • Downgrade from Fabric OS 6.3 to 6.1.2_cee1 is nondisruptive if ethsw has never been enabled with Fabric OS 6.3. • HA Failover of CP blades in DC SAN Backbone or DC04 SAN Director also results in disruption of traffic through the 10/24 blades. • Connecting a 2408 FCoE Converged Network Switch to an FCR-capable switch with fcrbcast config enabled will cause a storm of broadcast traffic, resulting in termination of iswitchd. • When rebooting a DC SAN director or DC04 SAN director with DC SAN 10/24 FCoE blade, Qlogic CNA and LSAN zoning, the switch becomes unresponsive for a period of time. This is due to the CNA sending excessive MS queries to the switch. • A DC SAN 10/24 FCoE blade installed in the highest numbered slot of a DC SAN director or DC04 SAN director does not send out FIP unsolicited advertisements. Therefore, it does not support FCoE functionality when installed in this slot. Virtual Fabrics • On VF-capable platforms, the VF feature (initially supported with Fabric OS 6.2.0a) must be enabled in order to utilize the related capabilities, including logical switches and logical fabrics. Any switch shipped from the factory with 6.3.1a or later installed that is capable of supporting VF will have it enabled by default. • When creating logical fabrics that include switches that are not VF-capable, it is possible to have two logical switches with different FIDs in the same fabric. Be sure to verify that the FIDs match for all switches in the same logical fabric. • In order to support non-disruptive Hot Code Load on an HP StorageWorks 8/40 SAN Switch with VF enabled, the total zoning DB size for the entire chassis should not exceed 1 MB. • A switch with VF enabled cannot participate in a fabric that uses IP filter or password database distribution or administrative domains. You must disable the VF feature before deploying it in a fabric that uses these features. • VF is not supported on the 1606 Extension SAN switch. HP StorageWorks Fabric OS 6.3.2b Release Notes 25

keep the login group name unique in the fabric-wide configuration.
•
Ethernet switch services must be explicitly enabled using the command
fosconfig –enable
ethsw
before powering on a DC SAN Director Switch 10/24 FCoE Blade. Failure to do so causes
the blade to be faulted (fault 9).
•
To support nondisruptive firmware upgrades on the DC SAN Backbone Director/DC04 SAN
Director, a new service,
ethsw
, is being introduced to enable Ethernet switching on the DC SAN
Director Switch 10/24 FCoE Blade in Fabric OS 6.3. LAN switching is disabled by default in
Fabric OS 6.3. The user must explicitly enable Ethernet switch service using the command
foscon-
fig –enable ethsw
to prevent FC traffic interruption.
•
Upgrading DC SAN Backbone Director/DC04 SAN Director with DC SAN Director 10/24 FCoE
blade from Fabric OS 6.x to 6.3 is nondisruptive. You can enable
ethsw
after upgrading without
interrupting FC traffic. Upgrading firmware on the 2408 FCoE Converged Network Switch disrupts
the FC traffic.
•
For HP StorageWorks DC SAN or DC04 SAN Directors with one or more SAN Director Switch
10/24 FCoE blades installed, downgrading or upgrading the Fabric OS 6.3 firmware to another
version disrupts traffic through the blades. HA Failover of CP blades in either of these directors
disrupts traffic through the 10/24 FCoE blades.
•
Upgrades from Fabric OS 6.3 to future releases will be nondisruptive to data traffic and will have
behavior similar to a CP failover;
ethsw
remains unchanged.
•
Downgrade from Fabric OS 6.3 to 6.1.2_cee1 is disruptive if
ethsw
is enabled on Fabric OS
6.3.
•
Downgrade from Fabric OS 6.3 to 6.1.2_cee1 is nondisruptive if
ethsw
has never been enabled
with Fabric OS 6.3.
•
HA Failover of CP blades in DC SAN Backbone or DC04 SAN Director also results in disruption
of traffic through the 10/24 blades.
•
Connecting a 2408 FCoE Converged Network Switch to an FCR-capable switch with
fcrbcast
config
enabled will cause a storm of broadcast traffic, resulting in termination of
iswitchd
.
•
When rebooting a DC SAN director or DC04 SAN director with DC SAN 10/24 FCoE blade,
Qlogic CNA and LSAN zoning, the switch becomes unresponsive for a period of time. This is due
to the CNA sending excessive MS queries to the switch.
•
A DC SAN 10/24 FCoE blade installed in the highest numbered slot of a DC SAN director or
DC04 SAN director does not send out FIP unsolicited advertisements. Therefore, it does not support
FCoE functionality when installed in this slot.
