chsystemip

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

Syntax

chsystemip [ -clusteripipv4addr ] [ -gwipv4addr ] [ -masksubnet_mask ] [ -clusterip_6ipv6addr ] [ -gw_6ipv6addr ] [ -prefix_6prefix ] -portsystem_port
chsystemip [ -noip ] [ -noip_6 ] [ -portsystem_port ]

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.

IP address list formats provides IP address formats that are supported.
Table 1. IP address list formats
IP type IP address list format
IPv4 1.2.3.4
Full IPv6 1234:1234:abcd:0123:0000:0000:7689:6576
Full IPv6, leading zeros suppressed 1234:1234:abcd:123:0:0:7689:6576
IPv6 with zero compression 1234:1234:abcd:123::7689:6576
