Technical data

DescriptionTopic

• All offline diagnostics commands should be used only when the switch is dis-

abled.

• 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.

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. Typ-

ically, 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.

System boot

If the user tries to save more than 512 monitors using the perfCfgSave command,

some of the monitors may be lost.

Performance Monitoring

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.
