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 5.0.x to 5.2.1b is supported, but upgrading from Fabric OS 4.4.0 or a previous release directly to 5.2.1b is not. Upgrading a switch from Fabric OS 4.4.0 or a previous release to 5.2.1b requires a two-step process: first upgrade to Fabric OS 5.0.x or 5.1.x and then upgrade to 5.2.1b. The following conditions must be met before upgrading to Fabric OS 5.2.1b: • 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. 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 5.2.1b, downgrade will be disruptive and require cold reboot. • A Fabric OS 5.2.1b configuration file cannot be used on the same switch after the switch has been downgraded to firmware version 5.0.x or 5.1.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. Fabric OS 5.2.1b updates The following sections list important updates. MSA 1000 and MSA 1500 For the FC4-48, if an MSA 1000 or MSA 1500 is directly connected to ports 32-47 of the blade, it will log in as a G-port. This has been seen on both active-active (v7.00.B700) and active-passive (v4.24.B272) MSA firmware. Ports 0 through 31 of this card log in correctly as F-ports. To prevent this from occurring when running Fabric OS 5.2.0b, simply move the MSA connections to lower ports. Fabric OS versions 5.2.1 and 5.2.1a - not released or supported Please note that HP did not release Fabric OS versions 5.2.1 or 5.2.1a. All fixes to Fabric OS versions 5.2.1 and 5.2.1a are reflected in this current Fabric OS 5.2.1b release. Devices connected to the 400 MP Router or MP Router Fibre Channel ports In rare instances, devices connected directly to the 400 MP Router or MP Router Blade Fibre Channel ports may not be discovered. The workaround is to perform an operating system I/O re-scan to re-establish device connectivity. HP StorageWorks Fabric OS 5.2.1b release notes 9
