HP StorageWorks Fabric OS 5.3.0b Release Notes (AA-RWEYF-TE, October 2007)

Firmware upgrade/
downgrade
• When upgrading from Fabric OS 5.1.0x to 5.2 .0x or 5.3.0x, if two or more
inter-fabric links (IFLs) connect to an edge fabric, one IFL will stay online and
the other IFLs will go online and offline. This will cause a temporary traffic
disruption going from multiple IFLs to one IFL and then back to multiple IFLs.
This is due to the new front domain consolidation 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 5.3.0x or 5.2.x, FC trafficwillbe
disrupted if there is front domain consolidation prior to the downgrade, even
inthecaseofasingleIFL.
• 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 di sabled.
Fabric OS—CLI
commands
• Obsolet
e commands include slotOff and slotOn;useslotPowerOff
and slot
PowerOn instead. The portLogPortShow command is also now
obsolet
e.
• This re
lease does not support underscore (_) as part of the nam e for dd and
ddset i
ntheiscsicfg command.
• When p
erforming a configdownload, you may receive a message stating
"configDownload not permitted.” This indicates that an invalid parameter was
passed to the switch.
The invalid parameter could be from a switch security policy, such as the
nl
password policy, or the NTP server address. This causes a partial
nl
configuration to be downloaded onto the switch.
For example, when an NTP server address is invalid, configdownload fails
nl
and all data processed prior to the NTP server address data had already been
nl
saved in the switchand cannot be backed out. To fix the problem, correct the
nl
invalid parameter and re-issue the configdownload command.
Distance mode
Distance setting is not persistent. After a configuration uploads and downloads,
distance settings reset 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 t ake 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.
• F
CR switch does not support edge fabrics that consist of McDATA switches
with ‘domain ID offset’. The EX_Port c onnected to that edge fabric may fail
the RDI process and will not c ome up. EX_Ports come up disabled (failed to
init in tim e) if attached to a Native mode switch running EOS 9.x that has
non-default 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.
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.
• Installing new SF Ps during POST m ay 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
diagSetBurnin.
• IfthereISLsresideontheswitchthatarenotusedforroutingbecausethey
