HP StorageWorks Fabric OS 5.3.1b release notes (5697-7644, August 2008)

Topic Description
Firmware upgrade/
downgrade
• When upgrading from Fabric OS 5.1.x to 5.2.x or 5.3.x, if two or more
inter-fabric links (IFLs) connect to an edge fabric, one IFL will stay online and
the other IFLs will go onlin e 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 IFL s connected to the same edge share the same front domain.
• When downgrading from Fabric OS 5.3.x or 5.2.x, FC trafficwillbedisrupted
if there is front domain consolidation prior to the downgrade, even in the
case of a sin gle IFL.
• Upon firmware download the FC4-16IP Blade do es not preser ve disabled
GE_Ports in disabled state. If you want to retain GE_Port s in a disabled state
across firmware download, you must configure th em as persistently disabled.
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
leasedoesnotsupportunderscore(_)aspartofthenamefordd and
ddset i
ntheiscsicfg command.
• When p
erforming a configdownload, you may receive a message stating
"conf
igDownload not permitted.” This indicates that an invalid
param
eter was passed to the switch.
The in
valid 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 a
ll data processed prior to the NTP server address data had already been
nl
saved in the switch and cannot be backed out. To fix the problem, correct the
nl
invalid parameter and reissue 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
com
mand fcrDisable may take up to 8 minutes to complete. If the
MP R
outer is replaced by a B-Series MP Router Blade (FR4-18i) or an HP
Sto
rageWorks 400 MP Router, the command completes immediately.
• EX
_Por t trunking is not enabled by default.
• FC
R 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
w
ith ‘domain ID offset’. The EX_Port connected to that edge fabric may fail
the RDI process and will not come up. EX_Por ts come up disabled (failed to
initialize in time) 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 G A_NXT name server query
to discover devices through an FCR switch since the query is mishandled
by the FCR.
Secur ity
Remove a ny 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 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
diagSetBurnin.
• If the ISLs reside on the switch that are not used for routing bec ause they have
higher link costs, disable the links before running spinfab.
