Problem: A node canister has a location node error

The node error that is listed on the service assistant home page or in the event log
can indicate a location error.
The node error, that is listed on the service assistant home page, can be classified
as a location error. This indicates that the node canister, or the enclosure midplane
has been moved or changed. This is normally due to a service action not being
completed or not being implemented correctly.
There are a number of different conditions that report as a location error. Each
condition is indicated by different node error. To find out how to resolve the node
error, go to "Procedure: Fixing node errors" on page 220.
Be aware that after a node canister has been used in a system, the node canister
must not be moved to a different location, either within the same enclosure or in a
different enclosure because this might compromise its access to storage, or a host
application's access to volumes. Do not move the canister from its original location
unless directed to do so by a service action.

Ethernet network. If necessary, change the network configuration or see
"Procedure: Changing the service IP address of a node canister" on page 220 to
change the service IP address of a node.
IP address 192.168.70.121 subnet mask 255.255.255.0 is preconfigured on Ethernet
port 1 of the upper canister, canister 1. The service IP address 192.168.70.122
subnet mask 255.255.255.0 is preconfigured on Ethernet port 2 of the lower
canister, canister 2.
You might not be able to access these addresses because of the following
conditions:
– These addresses are the same as the addresses that are used by other devices
on the network.
– These addresses cannot be accessed on your network.
– There are other reasons why they are not suitable for use on your network.
If the previous conditions apply, see "Procedure: Changing the service IP
address of a node canister" on page 220 to change the service IP address to one
that works in your environment.
If you are unable to change the service address, for example, because you cannot
use a USB flash drive in the environment, see "Procedure: Accessing a canister
using a directly attached Ethernet cable" on page 221.
