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

Topic Description
HA
If there is an already segmented port a nd backbone devices are exported to
an edge fabric, a build fabric/fabric reconfiguration can occur after running
haFailover. Ensure that there no segmented port exist before upgrading
firmware.
Fabric Merge
Do not try to me
rge 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.
Scalability
• 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.
FRU insertion
The FW_FRU_INSERTED message is displayed twice when a power supply FRU
is inserted and powered on. There is no functional impact.
System boot
Not al
l 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.
Performance Monitoring
If the user t ries to save more than 512 monitors using the perfCfgSave
command, some of the monitors may be lost.
Management — Proxy
switches
If you using a Fabric OS 4.x switch as an API or SMI-S proxy to manage a 5.1.0
switch, you must be running Fabric OS 4.4.0d.
FCIP
• Fra
me drops observed on FCIP slow links:
•Th
e frame drops occur when the FCIP tunnel bandwidth is set to 10 Base-T
(1
0Mbps), E1 (1.048Mbps), or T1 (1.544Mbps).
•Wi
th E1 or T1, frames drop even without a n impaired link.
•W
ith 10 Base-T, frame drops may be observed when a low impairment
i
sputtothelink.
• T
he portperfshow command indicated incorrect (smaller) bidirectional
throughput on the FCIP tunnel when Fastwrite/Tape Pipelining is enabled.
• Fastwrite/Tape Pipelining did not inform user when it failed due to multiple
equal paths configured on 2 GbE ports.
• Backup jobs initiated from the Symantec BackupExec application slowed
noticeably after adding significant I/O traffic from regular hosts and targets to
the FCIP tunnel. A port-based routing policy must be used for Tape devices.
portcfgdefault
command function
change for the Brocade
4Gb SAN Switch for HP
c-Class BladeSystem
Beginning with Fabric OS 5.2.1 b, the portcfgdefault command now resets
the configuration to HP factory default port settings.
Broadcast Zones
In Fabric OS 5.3.0 and later, a zone with the name “broadcast” (case-sensitive)
is a special zone for setting up recipients of broadcast packets. In Fabric OS
versions earlier than 5.3.0, a zone named “broadcast” does not have special
significance. Therefore, you must make sure that if a broadcast zone is configured,
thentheactiveandstandbyCPsusethesameFabricOSversion.Otherwisean
HA failover might change the zone configuration.
