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. NOTE: For information about specific versions of Fabric OS support for FICON, see the B-series FICON Connectivity Stream. HP StorageWorks Fabric OS 6.4.1 Release Notes 33
