Topic Description

FC Routing

• 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 princi pal’. The EX_Port connected to that edge fabric will not c ome up.

• FCR switch does not support edge fabrics that consist of McDATA switches

with ‘domain ID offset’. The EX_Por t connected to that edge fabric may fail

the RDI process and will not come up. EX_Ports come up disabled (failed to

init in time) if a t tached 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 ofﬂ ine 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.

• IfthereISLsresideontheswitchthatarenotusedforroutingbecausethey

have higher link costs, disable the links before running spinfab.

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 there no segmented port exist before upgrading

ﬁrmware.

IPSec for B-Series MP

Router Blade (FR4–18i)

• IPSec implementation details:

• Pre-shared key

• Main mode (IKE negotiation protocol)

• Tunnel mode in Encapsulating Security Payload (ESP)

• IPSec speciﬁc statistics not provided.

• No NAT or IPV6 support

• FastWrite and Tape Pipelining will not be suppor ted in conjunction with secure

tunnels.

• Jumbo frames will not be supported on secure tunnels.

• ICMP redirect is not supported for IPSec-enabled tunnels.

• Only a single secure tunnel will be allowe d on a port. Non-secure tunnels will

not be allowed on the same p ort as secure tunnels.

• Modify operations are not allowed on secure tunnels. To change the

conﬁguration of a secure tunnel, you must ﬁrst delete the tunnel and then

re-create it with the desired options.

• Onlyasinglerouteissupportedonaninterfacewithasecuretunnel.

• An IPSec tunnel cannot be created using the same local IP address if ipperf is

active and using the same local IP a ddress (source IP address).

• Unidirectional supported throughput is ~104Mbytes/sec and bidirectional

supported throughput is ~90Mbytes/sec.

• An IPSec tunnel takes longer to come online than a non-IPSec tunnel.

Fabric Merge

Do not try to merge fabrics with conﬂicting domain IDs over a VE_P ort. Before

merging t wo fabrics over FC-IP with VE_Ports at each end, HP recommends that

all domain ID and zoning conﬂicts be resolved.
