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

access. Thus, if one a ttempts 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 ﬁrst LAN detected whose IP address is n ot 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 d etection is

inﬂuenced by Microsoft Windows and is not guaranteed.

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

appliance is b ooted up. If only one is connected, HA FM interprets this as a single

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

sessions.

Workaround

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 private LAN. You must also have the public L A N connection active when the

HAFM appliance 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 cl

ient sessions.

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

the public LAN (to listen for remote client connections). To conﬁgure this feature,

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

IP address HAFM should use as the public LAN.

For det

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

If the p

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

must b

Known issues

This section describes the known issues related to the 1U HA FM appliance a nd the

HAFM software.

Sett

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

mana

gement to switches

When changing the HAFM appliance time to an earlier time, the Ethernet link to

directors and e d ge switches may be lost, or an open element manager may close.

When

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

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