HP StorageWorks Fabric OS 5.3.2b release notes (5697-0075, July 2009)

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 Router,
the command completes immediately.
EX_Port trunking is not enabled by default.
FCR switch does not support an edge fabric with one McDATA switch set to never
principal. The EX_Port connected to that edge fabric will not come up.
FCR switch does not support edge fabrics that consist of McDATA switches with
domain ID offset. The EX_Port connected to that edge fabric may fail the RDI process
and will not come up. EX_Ports come up disabled (failed to initialize in time) if
attached to a Native mode switch running EOS 9.x that has nondefault DID offset
configured.
Device discovery may fail when an HBA uses the GA_NXT name server query to
discover devices through an FCR switch, since the query is mishandled by the FCR.
FC Routing
Remove any password enforced expiration of admin or root accounts before
downgrading firmware to 5.0.1 or earlier versions.
Security
All offline diagnostics commands should be used only when the switch is disabled.
Installing new SFPs during POST may cause POST to fail. Install SFPs only when 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 diagSet- Burnin.
If the ISLs reside on the switch that are not used for routing because they have higher
link costs, disable the links before running spinfab.
Diagnostics
If there is an already segmented port and backbone devices are exported to an
edge fabric, a build fabric/fabric reconfiguration can occur after running
haFailover. Ensure that no segmented port exists before upgrading firmware.
HA
Do not try to merge fabrics with conflicting domain IDs over a VE_Port. Before merging
two fabrics over FC-IP with VE_Ports at each end, HP recommends that all domain
ID and zoning conflicts be resolved.
Fabric Merge
Support for Default Zoning policies has been added to Fabric OS 5.1.0. Typically,
when you issue the cfgDisable command in a large fabric with thousands of
devices, the name server indicates to all hosts that they can communicate with each
other. To ensure that all devices in a fabric do not see each other during a
cfgDisable operation, you can activate a Default Zone with policy set to no
access. If Default zoning policies show enabled, all cfgEnable/disable
commands and zoning changes must be run from a switch in the fabric running
Fabric OS 5.1.0/5.2.0a.
In large fabrics with more than 1,000 ports, HP recommends that the MS Platform
Database be disabled. The Platform DB must also be disabled before downgrading
to earlier versions of Fabric OS. This can be done using the msPLMgmtDeactivate
command.
Scalability
The FW_FRU_INSERTED message is displayed twice when a power supply FRU is
inserted and powered on. There is no functional impact.
FRU insertion
Not all Fabric OS services run when the prompt becomes available during boot up.
Wait for all the services to come up before using the switch or performing zoning
actions.
