FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks HA-Fabric Manager Release Notes (AA-RUR6G-TE, August 2005)

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

thepublicLANortheprivateLAN.Thoughthedirectorsandedgeswitchescanbe

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

access. Thus, if one attempts to a ccess 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 ﬁrst 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 L A N. 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.

Workaroun

There are a two ways to ensure the pubic and private designations of the LANs.

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

the privat

e LAN. You must also have the public LAN connection active when the

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

connection conﬁ g uration, and the 10.x.x.x LAN is designated as the LAN for

remote client sessions.

• You can c

onﬁgure a speciﬁed Ethernet interface on the HAFM appliance to be

the pub

lic LAN (to listen for remote client connections). To con ﬁgure this feature,

you mus

t manually edit a ﬁle on the HAF M appliance to explicitly specify which

IP address HAFM should use as the public LAN.

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

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

must be edited again to reﬂect the new IP address.

Kno wn issues

This section describes the known issues related to the 1U HAFM appliance and the

HAFM software.

Setting date/time of HAFM appliance to earlier time may cause loss of

management to switches

When

changing the H AFM appliance time to an earlier tim e, the Ethernet link to

directors a nd edge switches may be lost, or an o pen element manag er may close.

When attempting to reopen the element manager, the error message “The link to the

pro

duct is not available: Connection lost“ may be displayed.
