Public And Private Lan Designations; Remote Access To The Public Lan; Out-Of-Band Access - HP 316095-B21 - StorageWorks Edge Switch 2/24 User Manual

Public and private LAN designations

In a dual LAN configuration, both LANs must be connected when the HAFM appliance boots. If
only one is connected, the HAFM appliance interprets this as a single LAN configuration, and the
connected LAN is designated as the public LAN.
The HAFM application 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, the first LAN detected by
the HAFM application is designated as the public LAN. This order of detection is influenced by
Microsoft Windows and not guaranteed.
There are a two ways to ensure the pubic and private designations of the LANs:
• Assign the private LAN IP address, 10.x.x.x, to the LAN you want designated as the private
LAN. You must also have the public LAN connection active when the HAFM appliance is
booting up.
• Configure a specified Ethernet interface on the HAFM appliance to be the public LAN by
manually editing a file on the HAFM appliance to explicitly specify which IP address the HAFM
application should use as the public LAN.
Perform the following to configure an Ethernet interface:
• Open the config.properties file in directory C:\Program Files\HAFM\, and add
the following line:
ServerRmiIpAddress=x.x.x.x
where x.x.x.x is the IP address assigned to the Ethernet LAN adapter which is to be used
as the public LAN. This entry is case sensitive and must be made exactly as shown. After this
line has been added, reboot the HAFM appliance.
NOTE: Rebooting the server does not impact the Fibre Channel operations of any edge switch or
director. Only monitoring switch operations, logging events, and implementing configuration
changes are interrupted.

Remote access to the public LAN

If the public LAN IP address of the HAFM appliance is changed, you must edit the
config.properties file to reflect the new IP address.
Remote workstations are not supported on the secondary adapter, and must always connect to the
public adapter.
For details on configuring remote workstations, see
page 261.

Out-of-band access

Besides the HAFM application and Element Managers on the HAFM appliance, out-of-band
(non-Fibre Channel) management access to HP directors and switches is provided through the
following:
