HP StorageWorks HA-Fabric Manager Release Notes, V08.08.00 (AA-RUR6H-TE, December 2005)

• Which LAN is to be the private LAN for communication between the HAFM

appliance, and the Directors and Edge Switches that the HAFM appliance

manages?

• Which LAN is to be the public LAN for communication between the HAFM

appliance and computers seeking remote client access to the HAFM appliance?

The issue arises because either LAN connection on the HAFM appliance can be the

public LAN or the private LAN. Though the Directors and Edge Switches can be

managed via either LAN, the public LAN is the only one that can suppor t remote client

access. Thus, if one attempts to access the HAFM appliance via a remote client session

and is unknowingly using what has been designated as the private LAN, the remote

session is not allowed. The IP address that the HAFM appliance has determined to be

thepublicLANwhichsupportsremoteclientaccess,displaysHAFMwhichdisplays

after selecting SAN > Server Properties.

HAFM designates the public LAN as the ﬁ rst LAN detected whose IP address is not the

reserved private subnet 10.x.x.x. Thus, if neither IP address is 10.x.x.x,theﬁrst

L AN detected by HAFM is designated as the public LAN. This order of detection is

inﬂuenced by Microsoft Windows and is not guaranteed.

For a dual LAN conﬁguration, both LANs must be connected when the HAFM

appliance is booted up. If only one is connected, HAFM interprets this as a s ingle

LAN conﬁguration, and the connected LAN is designated as the LAN for remote client

sessions.

Workaround

There are

two ways to ensure the public and private designations of the LANs.

• If you use a private L A N IP address, this causes this LAN to be designated as

the private L AN. You must also have the public LA N connection active when the

HAFM app

liance is booting up, or else HAFM interprets this as a single LAN

connect

ion conﬁg uration, and the 10.x.x.x LAN is designated as the LAN for

remote client sessions.

• You can conﬁgure a speciﬁed Ethernet interface on the HAFM appliance to be

the public L AN (to listen for remote client connections). To con ﬁgure this feature,

you must manually edit a ﬁle on the HAFM appliance to explicitly specify which

IP add

ress HAFM should use as the public L AN.

For detailed instructions, see HP StorageWorks HA-Fabric Ma nager User Guide.

If the public LAN IP address of the HAFM appliance is ever changed, this ﬁle

must be edited again to reﬂect the new IP address.

Performance graphs inaccurate for time period when HAFM appliance is s hut

down

If the HAFM appliance has b een shut down or the H AFM application and Ser vices have

been stopped, after restarting the performance graphs continue and draw a ﬂat line

from the stop point to the n ew start point. This indicates a level of performance d u ring
