HP A7533A - Brocade 4Gb SAN Switch Base Release Note page 21

For routed SANs with M-EOS switches in an edge fabric, upgrades to Fabric OS 6.2.2a are
nondisruptive if all EX_Ports to M-EOS edge fabrics are attached to 4/256 SAN Directors with an
MP Router blade (FR4-18i).
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 6.2.2a, 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 6.2.2a 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 6.2.2a cannot be upgraded to
Fabric OS 6.3.x versions earlier than 6.3.0d.
Firmware upgrade instructions
IMPORTANT:
HP recommends that users upgrade to Fabric OS 6.2.2a as soon as possible. Upgrading to Fabric
OS 6.2.2a is allowed only from Fabric OS 6.1.x. For guidelines, see
recommendation" on 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
functionality moved to
