Use the chsystemip command to modify
the Internet Protocol (IP) configuration parameters for the clustered
system (system).

Parameters
- -clusteripipv4addr
- (Optional) Changes
the IPv4 system IP address. When you specify a new IP address for
a system, the existing communication with the system is broken.
Important: The -clusterip parameter cannot be used if there are any active IPv4 partnerships
with the system.
- -gwipv4addr
- (Optional) Changes the IPv4 default gateway IP address
of the system.
- -masksubnet_mask
- (Optional) Changes the IPv4 subnet mask of the system.
- -noip
- (Optional) Unconfigures
the IPv4 stack on the specified port, or both ports if none is specified.
Note: This parameter does not affect node service address
configurations.
- -clusterip_6ipv6addr
- (Optional) Sets the IPv6 system address
for the port.
Important: The -clusterip_6 parameter cannot be used if there are any
active IPv6 partnerships with the system.
- -gw_6ipv6addr
- (Optional) Sets the IPv6 default gateway address for the port.
- -prefix_6prefix
- (Optional) Sets the IPv6 prefix.
- -noip_6
- (Optional)
Unconfigures the IPv6 stack on the specified port, or both ports if
none is specified.
Note: This parameter does not affect
node service address configurations.
- -portsystem_port
- (Required) Specifies which
port (1 or 2) to apply changes to.
This parameter is required unless the noip or noip_6 parameter is used.
Description
This command modifies IP configuration parameters for the system.
The first time you configure a second port, all IP information is
required. Port 1 on the system must always
have one stack fully configured.
There are two active system
ports on the configuration node. There are also two active service
ports on any node in which you are performing a service action.
If the system IP address is changed, the open command-line shell
closes during the processing of the command. You must reconnect to
the new IP address if connected through that port.
If there is no port 2 available on
any of the system nodes, the chsystemip command
fails.
The
noip and
noip_6 parameters can be specified together only if the
port is also specified. The
noip and
noip_6 parameters cannot be specified with any parameters other than
port.
Note: The noip and noip_6 parameters do not affect node service
address configurations.
Port 1 must have an IPv4 or IPv6 system
address. The configuration of port 2 is optional.
Service IP addresses for all ports and stacks are initialized to
Dynamic Host Configuration Protocol (DHCP). A service IP address is
always configured.
Note: If the console_ip is the same as IP address system port 1, Internet
Protocol Version 4 (IPv4) followed by IPv6, change the console_ip when the system IP is changed. If the console_ip differs from the system port 1 IP address, do not change the console_ip when the system IP is changed.
To modify an IP address, list the IP address of
the system by issuing the lssystem command. Modify
the IP address by issuing the chsystemip command.
You can either specify a static IP address or have the system assign
a dynamic IP address.
Table 1 provides IP address formats
that are supported.
