• If you use the Web console or CLI console to change an IPv6 address that
is connected to the management module, the IPv6 connection is
disconnected.
• To use ServerConductor/Blade Server Manager, HA monitor, or LPAR
manager, use an IPv4 network.
• To connect to a server blade through an IPv6 network, the server blade
firmware must support IPv6 networks.
• Switch modules do not support connection via IPv6 networks.
• To use Stateless Address Autoconfiguration on a server blade, the server
blade firmware must support the functionality.
• To connect a management module via an IPv6 network, specify a static
address. You cannot enable only the stateless address.
• To connect HSCM and a management module via an IPv6 network,
specify a static address and disable the stateless address.
• To connect to a management module via an IPv6 network, set global
unicast addresses for the IPv6 addresses. For default gateways, set the
link local address or global unicast address of the router that exists in the
same link as the management module. We recommend setting the link
local address.
DNS server setting
The DNS server can register a maximum of three DNS servers for IPv4
addresses and a maximum of three DNS servers for IPv6 addresses. You can
specify whether to give priority to the DNS servers for IPv4 addresses or to
the DNS servers for IPv6 addresses when resolving names.
A maximum of three DNS servers are used in total from DNS servers for IPv4
addresses and for IPv6 addresses. Either DNS servers for IPv4 addresses or
DNS servers for IPv6 addresses are preferentially used based on the priority
setting. If three servers are used, an access attempt will not be made to DNS
servers.
If four or more DNS servers are registered, DNS servers that have the fourth
or lower priority are not used.
