• After a firmware downgrade from Fabric OS 7.0.0a to 6.4.1x, ports are logged in as G_Port on an EVA 4400. • Ports are logged in as G_Ports after changing the port speed to 2 Gbps on an HP StorageWorks DC SAN Backbone Director Switch. Fabric OS feature compatibility in native connectivity modes Some earlier versions of Fabric OS supported E_Port connectivity with M-EOS-based products. With the introduction of HP Network Advisor, DCFM has been put into sustaining mode. Recommended Migration Paths to Fabric OS 7.0.0a Migrating from Fabric OS 6.4.x HP StorageWorks DC SAN Backbone Director Switch/HP StorageWorks DC04 SAN Director Switch units running any Fabric OS 6.4.x release can be non-disruptively upgraded to Fabric OS 7.0.0a. Any 8 Gbps platforms (other than HP StorageWorks DC SAN Backbone Director Switch/HP StorageWorks DC04 SAN Director Switch) using a Fabric OS version earlier than Fabric OS 6.4.1a must upgrade to Fabric OS 6.4.1a or later before non-disruptively upgrading to Fabric OS 7.0.0a. IMPORTANT: Upgrading these platforms from any Fabric OS 6.4.x release earlier than Fabric OS 6.4.1a to Fabric OS 7.0.0a will cause disruption to FC traffic. Upgrading any 8 Gbps platform operating at Fabric OS 6.4.1a or later to Fabric OS 7.0.0a is non-disruptive to FC traffic. Migrating from Fabric OS 6.3.x To non-disruptively migrate from Fabric OS 6.3.x to 7.0.0a, units should first load Fabric OS 6.4.1a (Fabric OS 6.4.1b should be used for encryption platforms, units operating in Access Gateway mode, or units with ports configured as EX or VEX for FCR), and then migrate to Fabric OS 7.0.0a. Fabric OS Upgrade and Downgrade Special Considerations The HP StorageWorks DC SAN Backbone Director Switch/HP StorageWorks DC04 SAN Director Switch units running any Fabric OS 6.4.x can be non-disruptively upgraded to Fabric OS 7.0.0a. This upgrade is non-disruptive to FC traffic only. Non-disruptive upgrade to Fabric OS 7.0.0a on 8 Gbps switches is allowed from Fabric OS 6.4.1a or later. Disruptive upgrades to Fabric OS 7.0.0a are allowed and supported from Fabric OS 6.3 (up to a two-level migration) using the optional -s parameter with the firmwaredownload command. If there are multiple node EGs (encryption groups) in a fabric, complete firmwaredownload on one node at a time before downloading on another node. The HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch does not support non-disruptive hot code loads (HCL). Upgrading the HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch to Fabric OS 7.0.0a is disruptive to the I/O through the switch. HP B-series Fabric OS 7.0.0a Release Notes 39

Fabric OS feature compatibility in native connectivity modes
Some earlier versions of Fabric OS supported E_Port connectivity with M-EOS-based products. With
the introduction of HP Network Advisor, DCFM has been put into sustaining mode.
Recommended Migration Paths to Fabric OS 7.0.0a
Migrating from Fabric OS 6.4.x
HP StorageWorks DC SAN Backbone Director Switch/HP StorageWorks DC04 SAN Director Switch
units running any Fabric OS 6.4.x release can be non-disruptively upgraded to Fabric OS 7.0.0a.
Any 8 Gbps platforms (other than HP StorageWorks DC SAN Backbone Director Switch/HP
StorageWorks DC04 SAN Director Switch) using a Fabric OS version earlier than Fabric OS 6.4.1a
must upgrade to Fabric OS 6.4.1a or later before non-disruptively upgrading to Fabric OS 7.0.0a.
IMPORTANT:
Upgrading these platforms from any Fabric OS 6.4.x release earlier than Fabric OS 6.4.1a to Fabric OS
7.0.0a will cause disruption to FC traffic. Upgrading any 8 Gbps platform operating at Fabric OS 6.4.1a
or later to Fabric OS 7.0.0a is non-disruptive to FC traffic.
Migrating from Fabric OS 6.3.x
To non-disruptively migrate from Fabric OS 6.3.x to 7.0.0a, units should first load Fabric OS 6.4.1a
(Fabric OS 6.4.1b should be used for encryption platforms, units operating in Access Gateway mode,
or units with ports configured as EX or VEX for FCR), and then migrate to Fabric OS 7.0.0a.
Fabric OS Upgrade and Downgrade Special Considerations
The HP StorageWorks DC SAN Backbone Director Switch/HP StorageWorks DC04 SAN Director
Switch units running any Fabric OS 6.4.x can be non-disruptively upgraded to Fabric OS 7.0.0a.
This upgrade is non-disruptive to FC traffic only. Non-disruptive upgrade to Fabric OS 7.0.0a on 8
Gbps switches is allowed from Fabric OS 6.4.1a or later.
Disruptive upgrades to Fabric OS 7.0.0a are allowed and supported from Fabric OS 6.3 (up to a
two-level migration) using the optional
-s
parameter with the
firmwaredownload
command. If
there are multiple node EGs (encryption groups) in a fabric, complete
firmwaredownload
on one
node at a time before downloading on another node.
The HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch does not support non-disruptive hot
code loads (HCL). Upgrading the HP 2408 24-10 GbE w/8-8 Gbps FC Base FCoE Switch to Fabric
OS 7.0.0a is disruptive to the I/O through the switch.
