HP StorageWorks Fabric OS 5.3.0a release notes (AA-RWEYE-TE, September 2007)

Firmware upgrade/
downgrade
• When upgrading from Fabric OS 5.1.0x to 5.2 .0x or 5.3. 0, if there are two
or more inter-fabric links (IFLs) connected to an edge fabric, one IFL will
stay online and the other IFLs will go online and offline. This will cause a
temporary traffic d isruption going from multiple IFLs to one IFL and then ba ck
to multiple IFL s. This is due to the new front domain c onsolidation feature in
Fabric OS 5.2.0, where the IFLs connected to the same edge share the same
front domain.
• When downgrading from Fabric OS 5.3.0 or 5.2.x, FC trafficwillbedisrupted
if th ere is front domain consolidation prior to the downgrade, even in the
case of a single IFL.
• Upon firmware download the FC4–16IP blade does not preserve disabled
GE_Ports in disabled state. If you want to retain GE_Ports in a disabled state
across firmware download, you must configure them as persistently disabled.
Fabric OS
—CLI
command
s
• The slotOff and slotOn commands are now obsolete; use slotPowerOff
and slotPowerOn instead. The portLogPortShow command is also now
obsolete.
• The QuickLoop feature and related commands are no longer supported on
Fabric OS versions 5.1.0 and later.
• When performing a configdownload, you may receive a message stating
"con
figDownload not permitted.” This indicates that an invalid parameter was
pass
ed to the switch.
The i
nvalid parameter could be from a switch security policy, such as the
pass
word policy, or the NTP server address. This causes a partial
con
figuration to be do wnloaded onto the switch.
For example, when an NTP server address is invalid, configdownload fails
and all data processed prior to the NTP server address data had already been
savedintheswitchandcannotbebackedout. Tofixtheproblem,correctthe
invalid parameter and re-issue the configdownload command.
Distance mode
Distance setting is not persistent. After a configuration uploads and downloads,
distance settings are lost and the desired distance is shown as 0.
FC Routing
• If an HP StorageWorks MP Router is present in the backbone fabric, the
command fcrDisable may take up to 8 minutes to complete. If the
MP Router is replaced by a B-Series MP Router blade (FR4-18i) or an HP
StorageWorks 400 MP R outer, the command completes immediately.
• EX_Port trunking is not enabled by default.
• Fabric OS 5.2.0 introduced the EX_Por t trunking feature. This feature should
be enabled only if the entire configuration is running Fabric OS 5.2.0 or
later. Enabling the EX_port trunking feature on a switch running Fabric OS
5.2 .0 or later in a configuration containing a Fabric OS 5.1.0 switch causes
the Fabric OS 5.1.0 switch to panic.
• When an unstable edge fabric that has multipl e EX_Por t connections is in a
transitional state, on rare occasions one of the EX_Ports may detect a FID
conflict and be disabled. If t his occurs, manually re-enable the port.
Secur ity
Remove any password enforced expiration of admin or root accounts before
downgrading firmware to 5.0.1 or earlier versions.
Diagnostics
• All offline diagnostics commands should be used only when the switch is
disabled.
• POST can fail if new SFPs are added during POST. SFPs should be added only
while the switch is online or if the switch is powered off.
• When you use the diagnostic commands systemVerification and
diagSetBurnin, the switch or blade faults when the burn-in error log
is full. Clear the burn-in log before running systemVerification or
diagSetBurnin.
• If there are ISLs present on the switch that are not used for routing because
they have higher link costs, disable the links before running spinfab .
