Ficon Support - HP 4400 Release Note

The HP StorageWorks DC SAN Director with HP StorageWorks DC Switch Encryption FC Blade
and the HP StorageWorks Encryption SAN Switch cannot be downgraded to a version earlier
than Fabric OS 6.2.0b.
After upgrading the Encryption SAN Switch and the DC SAN Director with DC Switch Encryption
FC Blade to Fabric OS 6.2.2e, you cannot downgrade them to a version earlier than Fabric OS
6.2.0d if HP SKM key vault is configured. Doing so will result in the loss of encryption services in
HP SKM environments.
If there are multiple node EGs in a fabric, complete the firmware download on one node at a time
before downloading on another node.
On the HP StorageWorks 8/8 and 8/24 SAN Switches and the Brocade 8Gb SAN Switch for
HP BladeSystem c-Class, do not use the -n option to downgrade from Fabric OS 6.2.2e to a
version earlier than 6.2.x. Using the -n option can cause the firmware versions to get out of sync,
resulting in rolling kernel panics. The switch will not recover and you will need to return it to your
supplier for repair via RMA. Switches using Integrated Routing and Fabric OS 6.2.2e cannot be
upgraded to Fabric OS 6.3.x versions earlier than 6.3.0d.
Firmware upgrade instructions
IMPORTANT:
Upgrading to Fabric OS 6.2.2e is allowed only from Fabric OS 6.1.x. For guidelines, see
(page 4).
NOTE: With the introduction of Fabric OS 6.1.1, certain features and functions were removed
from Web Tools (resident in the firmware) and migrated to the Data Center Fabric Manager (DCFM)
management application. This has been carried forward to Fabric OS 6.2.x. If you are not running
DCFM on your fabric, HP recommends that before upgrading to Fabric OS 6.2.x or later, you
review (page 28)
