HP StorageWorks Fabric OS 5.3.0b Release Notes (AA-RWEYF-TE, October 2007)

CAUTION:
Install port blades like the HP StorageWorks 4/48 SAN Director Blade (FC4–48) only after upgrading
to Fabr ic OS 5.2. 0a or later.
HP does not support directly upgrading from more than t wo previous releases. For example, upgrading
from Fabric OS 5.1.x to 5.3.0b is supported, but upgrading from Fabric OS 5.0.x or a previous release
directly to 5.3.0b 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 5.3.0b.
The following conditions must be met before upgrading to Fabric OS 5.3.0b:
• Device-based routing must not be in use, otherwise the upgrade will fail. You can use the
aptPolicy comm a nd 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 M TU value of 2284. However, Fabric OS 5.2.1x and 5.3.0x
supportanMTUvalueofupto2348. PriortodowngradingtheFabricOSto5.1.1youmust
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 5.3.0b,
downgrade will be disruptive and require cold reboot.
• AFabricO
S5.3.0bconfiguration file cannot be used on the same switch after the switch has
been down
graded 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.
