Integrated routing • To allow HCL on an 8/40 SAN Switch when using Integrated Routing, the edge switch connected to the 8/40 SAN Switch must be running Fabric OS 6.1 or later. • Integrated Routing EX_Ports are supported only in the base switch on a switch with VF enabled. To test Integrated Routing functionality, first disable the VF feature (fosconfig --disable vf). • Integrated Routing and Top Talkers cannot run concurrently in Fabric OS 6.3.x and later. To use Integrated Routing, be sure to disable Top Talkers before configuring EX_Ports. VEX device sharing • VEX edge to VEX edge device sharing is not supported. FC FastWrite When an FC FastWrite Initiator is moved to a port that does not have FC FastWrite enabled, I/O recovers and reverts to the slow path route (non-FC FastWrite). This change was introduced with Fabric OS 6.3. Native connectivity Fabric OS-based platforms operating in interopmode 2 or 3 should never be deployed in a fabric without at least one M-series switch. Fabric OS switches in interopmode 3 (McDATA Open Fabric Mode) do not support configuration of zoning without an M-series switch in the fabric. When migrating from M-series to B-series switches, all B-series switches should be configured to interopmode 0 (Brocade Native mode) after the last M-series switch has been removed from the fabric. M-EOSc switches may exhibit a behavior where they block all attached devices with a reason indication of Blocked Temporarily, Internal. This can occur when you power cycle the M-series switch while it was participating in a fabric with Frame Redirection zoning, a capability used for Fabric OS-based application or encryption services. If the switch is still participating in the fabric with Frame Redirection, issue the cfgsave command from a Brocade Fabric OS-based switch with the Frame Redirection zone in its defined zone database. If the M-EOS switch is no longer attached to the fabric with Frame Redirection zoning, issue the Config.Zoning.deleteSplZoneSet command via the CLI to the M-EOS switch. FCAP • If VF is enabled on a switch, HTTPS and FCAP certificates should always be imported in the Default Switch. Certificates imported in a non-Default Switch will not be available after a hafailover operation. • The pkicert (1.06) utility may cause evm errors, so each new switch should be isolated from the fabric in non-VF mode to install new certificates. FICON • For the DC SAN Backbone Director, FICON is not allowed with a 48-port blade in the Default Logical Switch. All ports on a 48-port blade must be assigned to a user-defined Logical Switch to use them in a FICON enabled switch. • The DC04 SAN Director is not supported for FICON Cascading in interopmode 2 or 3 for use in mixed fabrics with M-EOS platforms. 30

Integrated routing
•
To allow HCL on an 8/40 SAN Switch when using Integrated Routing, the edge switch
connected to the 8/40 SAN Switch must be running Fabric OS 6.1 or later.
•
Integrated Routing EX_Ports are supported only in the base switch on a switch with VF enabled.
To test Integrated Routing functionality, first disable the VF feature (
fosconfig --disable
vf
).
•
Integrated Routing and Top Talkers cannot run concurrently in Fabric OS 6.3.x and later. To
use Integrated Routing, be sure to disable Top Talkers before configuring EX_Ports.
VEX device sharing
•
VEX edge to VEX edge device sharing is not supported.
FC FastWrite
When an FC FastWrite Initiator is moved to a port that does not have FC FastWrite enabled, I/O
recovers and reverts to the slow path route (non-FC FastWrite). This change was introduced with
Fabric OS 6.3.
Native connectivity
Fabric OS-based platforms operating in interopmode 2 or 3 should never be deployed in a fabric
without at least one M-series switch. Fabric OS switches in interopmode 3 (McDATA Open Fabric
Mode) do not support configuration of zoning without an M-series switch in the fabric. When
migrating from M-series to B-series switches, all B-series switches should be configured to
interopmode 0 (Brocade Native mode) after the last M-series switch has been removed from the
fabric.
M-EOSc switches may exhibit a behavior where they block all attached devices with a reason
indication of
Blocked Temporarily, Internal
. This can occur when you power cycle the
M-series switch while it was participating in a fabric with Frame Redirection zoning, a capability
used for Fabric OS-based application or encryption services. If the switch is still participating in
the fabric with Frame Redirection, issue the
cfgsave
command from a Brocade Fabric OS-based
switch with the Frame Redirection zone in its defined zone database. If the M-EOS switch is no
longer attached to the fabric with Frame Redirection zoning, issue the
Config.Zoning.deleteSplZoneSet
command via the CLI to the M-EOS switch.
FCAP
•
If VF is enabled on a switch, HTTPS and FCAP certificates should always be imported in the
Default Switch. Certificates imported in a non-Default Switch will not be available after a
hafailover
operation.
•
The pkicert (1.06) utility may cause
evm
errors, so each new switch should be isolated from
the fabric in non-VF mode to install new certificates.
FICON
•
For the DC SAN Backbone Director, FICON is not allowed with a 48-port blade in the Default
Logical Switch. All ports on a 48–port blade must be assigned to a user-defined Logical Switch
to use them in a FICON enabled switch.
•
The DC04 SAN Director is not supported for FICON Cascading in interopmode 2 or 3 for
use in mixed fabrics with M-EOS platforms.
