HP ProLiant BL465c Server Blade - Manual (Page 26)

IPv6 addresses can be passed to HP SUM in command line arguments or using the HP SUM user
interface. In the HP SUM user interface, HP SUM automatically detects whether to use IPv4 or IPv6
on the Add Target screen. On the Find Targets screen if you choose to select to IP address range,
select IPv4 or IPv6. HP SUM supports both the short-name and full IPv6 notation. You do not need
to add the optional interface number when you enter the address.
If you cannot connect to the target server or receive a Discovery failed message when executing
HP SUM in an IPv6 environment, see
“Configuring IPv6 networks with HP SUM” (page 26) .
After you connect to the target server, all other HP SUM functions work identically. Log files for
IPv6 hosts are stored with all other HP SUM files in the /var/hp/log/ directories.
The only current limitation of HP SUM in a Linux IPv6 environment is that all remote target Linux-based
servers must have the iptables-ipv6 RPM file installed. You can find the file on the distribution media
for both Red Hat Enterprise Linux and Novell SUSE Linux Enterprise Server operating systems. HP
SUM uses this file to open a port in the IPv6 firewall to communicate with the Linux system that
runs HP SUM. Failure to install iptables-ipv6 results in HP SUM reporting a discovery failure unless
you disable the firewall.
Configuring IPv6 networks with HP SUM
You can deploy to remote targets in IPv6-based networks for Windows and Linux target servers.
Using HP SUM with IPv6 networks presents challenges for IT administrators.
For Windows-based servers, to communicate with remote target servers, HP SUM uses either
existing credentials or user-provided user name and password to connect to the admin$ share.
This share is an automatic share provided by Windows Server. After HP SUM connects to the
admin$
share, it copies a small service to the target server for the duration of the installation. After
this service starts, HP SUM uses this service to communicate between the local and remote target
server. During this process, HP SUM opens ports in the Windows firewall to enable HP SUM to
use SOAP calls over SSL to pass data among local and remote systems. These ports are defined
in the
“Enabling ports in HP SUM” (page 33) section. After the installation is completed or canceled,
HP SUM stops the remote service, removes it from the target server, closes the port on the Windows
firewall, and then releases the share to the target server admin$ share.
For Linux-based servers, to communicate to remote target servers, HP SUM starts by using the
user-provided user name and password to create a SSH connection to the target server. After HP
SUM connects, copies a small service to the target server for the duration of the installation. After
this service starts, HP SUM uses this service to communicate between the local and remote target
server. During this process, HP SUM opens ports in the iptables firewall to enable HP SUM to use
SOAP calls over SSL to pass data between the local and remote systems. These ports are defined
in
“Enabling ports in HP SUM” (page 33) . When the installation is completed or canceled, HP
SUM stops the remote service, removes it from the target server, closes the port in the iptables
firewall, and then closes the SSH connection to the target server.
