Firmware upgrades and downgrades Upgrading to FOS 6.3.0b is allowed only from FOS 6.2.0a or later. The policy to support one-level migration only, which began with FOS 6.0.0, provides more reliable and robust migrations. By having fewer major changes in internal databases, configurations, and subsystems, the system can perform the upgrade more efficiently, ensuring a truly seamless and nondisruptive process for the fabric. The one-release migration policy also reduces the number of upgrade-downgrade permutations that must be tested, allowing for thorough testing and verification of supported migration paths. The DC04 SAN Director cannot be downgraded to a release earlier than FOS 6.2.0a. All downgrades from FOS 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 FOS 6.2.0a or later before loading FOS 6.3.0b on the 4/32 SAN Switch. The 2408 FCoE Converged Network Switch does not support nondisruptive HCLs. When upgrading a 2408 FCoE Converged Network Switch from FOS 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 FOS 6.3 will lose functionality following a restart or disabling of ports. When the FC POD license is installed on a unit with FOS 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 FOS 6.3. If the FOS 6.2 switch is in the Federal Information Processing Standards (FIPS) mode, and has only LDAP authentication support, and is upgraded to FOS 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 FOS 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 FOS 6.3, and then import the certificate. FOS 6.3.0x does not support concurrent FC Routing (EX_Ports) and Top Talkers features. Upgrading to FOS 6.3.0x 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 FOS 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 FOS 6.3.0b as soon as possible to take advantage of the fixes and new features. Upgrading to FOS 6.3.0b is allowed only from FOS 6.2.x. For more guidelines, see "Update recommendation" on page 5 . HP StorageWorks FOS 6.3.0b Release Notes 23

Firmware upgrades and downgrades
Upgrading to FOS 6.3.0b is allowed only from FOS 6.2.0a or later. The policy to support one-level
migration only, which began with FOS 6.0.0, provides more reliable and robust migrations. By having
fewer major changes in internal databases, configurations, and subsystems, the system can perform
the upgrade more efficiently, ensuring a truly seamless and nondisruptive process for the fabric. The
one-release migration policy also reduces the number of upgrade-downgrade permutations that must
be tested, allowing for thorough testing and verification of supported migration paths.
The DC04 SAN Director cannot be downgraded to a release earlier than FOS 6.2.0a.
All downgrades from FOS 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 FOS 6.2.0a
or later before loading FOS 6.3.0b on the 4/32 SAN Switch.
The 2408 FCoE Converged Network Switch does not support nondisruptive HCLs.
When upgrading a 2408 FCoE Converged Network Switch from FOS 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 FOS 6.3 will lose functionality following a restart or disabling of
ports. When the FC POD license is installed on a unit with FOS 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 FOS 6.3.
If the FOS 6.2 switch is in the Federal Information Processing Standards (FIPS) mode, and has only
LDAP authentication support, and is upgraded to FOS 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
FOS 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 FOS 6.3,
and then import the certificate.
