Problem: A node canister has a location node error

The node error listed on the service assistant home page or in the event log can
indicate a location error.
A location error means 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.
A number of different conditions are reported as location errors. 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 206.
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.

Problem: SAS cabling not valid

This topic provides information to be aware of if you receive errors that indicate
the SAS cabling is not valid.
Check the following items:
v No more than five expansion enclosures can be chained to port 1 (below the
v No more than four expansion enclosures can be chained to port 2 (above the
v Do not connect a SAS cable between a port on an upper canister and a port on a
v In any enclosure, the same ports must be used on both canisters.
v No SAS cable can be connected between ports in the same enclosure.
v For any enclosure, the cables that are connected to SAS port 1 on each canister

If the previous conditions apply, see "Procedure: Changing the service IP
address of a node canister" on page 206 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 207.
