chnodeip

Use the chnodeip command to set or clear the node IP on the specified node Ethernet port.

Syntax

Parameters

-ip ipv4addr: (Optional) Specifies the Internet Protocol Version 4 (IPv4) address for the specified Ethernet port.
-noip: (Optional) Specifies that the IPV4 address is cleared from the specified Ethernet port. The default value is false.
-mask subnet_mask: (Optional) Specifies the IPv4 address mask for the specified Ethernet port.
-gw ipv4_gw: (Optional) Specifies the IPv4 gateway address for the specified Ethernet port.
-force: (Optional) Forces an IP address change for a node Ethernet port even if it causes the system to go into a degraded or offline state.
Important: Using the force parameter might result in a loss of access. Use it only under the direction of IBM® support personnel.
-vlan vlanid: (Optional) Specifies the numeric Virtual LAN identifier that the clustering port is part of. The value must be an integer.
-novlan: (Optional) Deletes or unsets the numeric Virtual LAN identifier the clustering port is part of.
panel_name: (Optional) Specifies the system or node on which the command is invoked. The value must be an alphanumeric.
-port_id integer: (Required) Specifies the port ID on which you want to configure node IP address. The ID can be a value in the range 1 - 28.

Description

This command sets or clears the node IP address on the specified node Ethernet port.

Note: If you receive error message CMMVC8012E - The operation did not complete in the time that is allowed, rerun the command.

Note: The satask chnodeip command displays an error if a storage administrator configures more than eight clustering IP addresses on an Ethernet port.
