HP StorageWorks Fabric OS 6.3.1c Release Notes (5697-0509 September 2010 - includes all 6.3.1x versions)

If migrating from Fabric OS 6.1.x, HP recommends that you use Fabric OS 6.2.2b as the migration
path to 6.3.1c in order to reduce the risk of exposure to known issues at earlier 6.2.x levels.
The DC04 SAN Director cannot be downgraded to a release earlier than Fabric OS 6.2.0a.
All downgrades from Fabric OS 6.2.0a require a restart and are disruptive to traffic. Platforms
supporting VF must have the feature disabled before downgrading to a release earlier than 6.2.0a.
To ensure nondisruptive hot code load (HCL), neighbor switches should be operating with Fabric OS
6.2.0a or later before loading Fabric OS 6.3.1c on the 4/32 SAN Switch.
The 2408 FCoE Converged Network Switch does not support nondisruptive HCLs. As a result, any
firmware upgrades are disruptive to the I/O through the switch. Similarly, a code load of DC SAN
Director or DC04 SAN Director with one or more DC SAN 10/24 FCoE blades disrupts traffic through
the blade.
When upgrading a 2408 FCoE Converged Network Switch from Fabric OS 6.1.2_cee1 to 6.3, verify
that the unit has both the FCoE and FC POD licenses installed (default for HP 2408 switches). Units
missing these licenses that are upgraded to Fabric OS 6.3 will lose functionality following a restart
or disabling of ports. When the FC POD license is installed on a unit with Fabric OS 6.1.2_cee1, the
licenseShow output will indicate that the license is not applicable on this platform. This
message can be ignored and will not appear once the unit has been upgraded to Fabric OS 6.3.
If a Fabric OS 6.2 switch is in the Federal Information Processing Standards (FIPS) mode, and has
only LDAP authentication support, and is upgraded to Fabric OS 6.3, login will fail. Therefore, if the
6.2 switch is in the FIPS mode, you should configure both LDAP and local authentications before
upgrading it to Fabric OS 6.3. When the switch is up, you can log in to the switch and import the
certificate again. If the switch is not in the FIPS mode, you can log in to the switch with LDAP after
upgrading to Fabric OS 6.3, and then import the certificate.
Switches using Integrated Routing and operating with Fabric OS 6.2.2x may not be upgraded directly
to Fabric OS 6.3.0a or 6.3.0b. Those units should be upgraded to Fabric OS 6.3.0c or later, or first
downgraded to a release earlier than 6.2.2.
Fabric OS 6.3x does not support concurrent FC Routing (EX_Ports) and Top Talkers features. Upgrading
to Fabric OS 6.3x requires that one of these features be disabled first.
The DC SAN Director with the DC Switch Encryption FC Blade and Encryption SAN Switch cannot
be downgraded to a version earlier than Fabric OS 6.2.0b.
If there are multiple node encryption groups (EGs) in a fabric, complete the firmware download on
one node at a time before downloading on another node.
Firmware upgrade instructions
IMPORTANT:
HP recommends that you upgrade to Fabric OS 6.3.1c as soon as possible to take advantage of the
fixes and new features. Upgrading to Fabric OS 6.3.1c is allowed only from Fabric OS 6.2.x. For
