Hitachi Global Link Manager Software Installation and Configuration Guide

Limitations on Operations in an IPv6 Environment
Note the following limitations when you use Global Link Manager in an IPv6
environment:
• Global Link Manager does not support IPv6-only environments. Set up the
OS such that both IPv4 and IPv6 can be used.
• You can only use global addresses as IPv6 addresses. Global-unique local
addresses (site-local addresses), and link-local addresses cannot be used.
• When specifying the IP address or host name of the Global Link Manager
server, we recommend that you use the host name. If you specify an IPv6
address, you might not be able to move from one window to another.
• In the list of hosts in the Global Link Manager GUI, hosts are managed for
each IP address. Therefore, a host that has both an IPv4 address and an
IPv6 address is registered as two hosts. After you migrate a host to an
IPv6 environment, manually delete the IPv4 address of the host from the
list of hosts. For details about the list of hosts in the Global Link Manager
GUI, see Help.
• Because the path availability information (path status log) for a host is
managed for each IP address, this information cannot be migrated even if
the connection method to the host is changed from IPv4 to IPv6.
Settings for Operations in an IPv6 Environment
If you use Global Link Manager that has been used in an IPv4 environment in
an IPv6 environment, edit the user_httpsd.conf file. The user_httpsd.conf
file is stored one of the following locations:
Hitachi-Command-Suite-Common-Component-installation-folder\uCPSB
\httpsd\conf\user_httpsd.conf
Caution: Stop Global Link Manager and Hitachi Command Suite Common
Component, and then edit the user_httpsd.conf file. After editing the file,
start Global Link Manager and Hitachi Command Suite Common Component
to apply the changes.
If you want to send an SNMP trap to the management server via IPv6, you
need to specify the properties in the server.properties file. For details
about how to specify the properties, see
Changing Global Link Manager
Environment Settings on page 3-23.
Note: During a new installation of Global Link Manage in an IPv6
environment, the installer automatically sets the Listen line in the
httpsd.conf file as described below.
Settings for IPv6
Remove the hash mark (#) at the beginning of the line Listen [::]:22015
(when the default setting is used). Specify the same port number as specified
in the Listen line for IPv4. The default value for the port number is 22015.
