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.
