NOTE: The B-Series MP Router Blade (for use with the 4/256 Director only) must run Fabric OS 5.1.0d or later. The Core Switch 2/64 does not support the B-Series MP Router Blade. Firmware upgrade instructions To access the latest Fabric OS 5.3.1b firmware, configuration files, and MIB files, see the following HP website: http://www.hp.com/go/san. CAUTION: Install port blades like the HP StorageWorks 4/48 SAN Director Blade (FC4-48) only after upgrading to Fabric OS 5.2.0a or later. HP does not support directly upgrading from more than two previous releases. For example, upgrading from Fabric OS 5.1.x to 5.3.1b is supported, but upgrading from Fabric OS 5.0.x or a previous release directly to 5.3.1b is not. Upgrading a switch from Fabric OS 5.0.x or a previous release to 5.3.0 requires a two-step process: first upgrade to Fabric OS 5.1.x or 5.2.x and then upgrade to 5.3.1b. The following conditions must be met before upgrading to Fabric OS 5.3.1b: • Device-based routing must not be in use, otherwise the upgrade will fail. You can use the aptPolicy command to verify the routing policy. • Chassis configuration options 3 and 4 are no longer supported for the 4/256 SAN Director. • Fabric OS 5.1.1 supports a maximum MTU value of 2284. However, Fabric OS 5.2.1x and 5.3x support an MTU value of up to 2348. Prior to downgrading the Fabric OS to 5.1.1 you must change the MTU size less than or equal to 2284. If the configuration of the target unit has an MTU value greater than 2284, the FCIP tunnels will not go online after firmware downgrade. CAUTION: If the 4/256 SAN Director integrates the FC4-48 Blade or any new software features in Fabric OS 5.2.0a, such as FCR trunking, you cannot downgrade below Fabric OS 5.2.0a. If you want to do so, you must (a) remove these features, (b) physically remove the Blade, and then (c) downgrade the firmware. • For any other new software features or increased scalability limits supported by Fabric OS 5.3.1b, downgrade will be disruptive and require a cold reboot. • A Fabric OS 5.3.1b configuration file cannot be used on the same switch after the switch has been downgraded to firmware version 5.1.x or 5.2.x. • When you downgrade to Fabric OS 5.0.x, you must also remove additional 5.1.x features and any installed B-Series MP Router blades.

HP does not support directly upgrading from more than two previous releases. For example, upgrading
from Fabric OS 5.1.x to 5.3.1b is supported, but upgrading from Fabric OS 5.0.x or a previous release
directly to 5.3.1b is not.
Upgrading a switch from Fabric OS 5.0.x or a previous release to 5.3.0 requires a two-step process:
fi
rst
upgrade to Fabric OS 5.1.x or 5.2.x and then upgrade to 5.3.1b.
The following conditions must be met before upgrading to Fabric OS 5.3.1b:
•
Device-based routing must not be in use, otherwise the upgrade will fail. You can use the
aptPolicy
command to verify the routing policy.
•
Chassis con

guration options 3 and 4 are no longer supported for the 4/256 SAN Director.
•
Fabric OS 5.1.1 supports a maximum MTU value of 2284. However, Fabric OS 5.2.1x and 5.3x
support an MTU value of up to 2348. Prior to downgrading the Fabric OS to 5.1.1 you must
change the MTU size less than or equal to 2284.
If the con
fi
guration of the target unit has an MTU value greater than 2284, the FCIP tunnels
will not go online after
fi
rmware downgrade.
CAUTION:
If the 4/256 SAN Director integrates the FC4-48 Blade or any new software features in Fabric OS
5.2.0a, such as FCR trunking, you cannot downgrade below Fabric OS 5.2.0a. If you want to do so, you
must (a) remove these features, (b) physically remove the Blade, and then (c) downgrade the
fi
rmware.
•
For any other new software features or increased scalability limits supported by Fabric OS 5.3.1b,
downgrade will be disruptive and require a cold reboot.
•
A Fabric OS 5.3.1b con
fi
guration
fi
le cannot be used on the same switch after the switch has
been downgraded to
fi
rmware version 5.1.x or 5.2.x.
•
When you downgrade to Fabric OS 5.0.x, you must also remove additional 5.1.x features and
any installed B-Series MP Router blades.
