a replacement enclosure chassis, and restart the
hardware remove and replace control enclosure
chassis procedure.
3. If this action does not resolve the issue, contact IBM
technical support. They will work with you to
ensure that the cluster state data is not lost while
resolving the problem.
Possible Cause-FRUs or other:
v Enclosure chassis (100%)
503 Incorrect enclosure type
Explanation: The node canister has been moved to an
expansion enclosure. A node canister will not operate
in this environment.
User response: Follow troubleshooting procedures to
relocate the nodes to the correct location.
1. Review the saved location information of the node
canister to determine which control enclosure the
node canister should be in.
2. Use the hardware remove and replace canister
procedures to move the node canister to the correct
location and move the expansion canister, that is
probably in that location, to here. If there is a node
canister that is in active state where this node
canister should be, do not replace that node canister
with this one.
504 No enclosure identity and partner node
matches.
Explanation: The enclosure vital product data
indicates that the enclosure chassis has been replaced.
This node canister and the other node canister in the
enclosure were previously operating in the same
enclosure chassis.
User response: Follow troubleshooting procedures to
configure the enclosure.
1. This is an expected situation during the hardware
remove and replace procedure for a control
enclosure chassis. Continue following the remove
and replace procedure and configure the new
enclosure.
Possible Cause-FRUs or other:
v None
505 No enclosure identity and partner has
cluster data that does not match.
Explanation: The enclosure vital product data
indicates that the enclosure chassis has been replaced.
This node canister and the other node canister in the
enclosure do not come from the same original
enclosure.

relocate nodes to the correct location.
1. Review the saved location information of the node
canister and the saved location information of the
other node canister in the enclosure (the partner
canister). The correct node canister is the one that
comes from the enclosure chassis that is being
replaced. The drives now in this enclosure should
also come from that enclosure.
2. Decide what to do with the node canister that did
not come from the enclosure that is being replaced.
a. If the other node canister from the enclosure
being replaced is available, use the hardware
remove and replace canister procedures to
remove the incorrect canister and replace it with
the second node canister from the enclosure
being replaced. The two node canister should
show node error 504 and the actions for that
error should be followed.
b. If the other node canister from the enclosure
being replaced is not available, check the
enclosure of the node canister that did not come
from the replaced enclosure. Do not use this
canister in this enclosure if you require the
volume data on the system from which the node
canister was removed, and that system is not
running with two online nodes. You should
return the canister to its original enclosure and
use a different canister in this enclosure.
c. When you have checked it is not required
elsewhere, follow the procedure to remove
cluster data from the node canister that did not
come from the enclosure that is being replaced.
Restart both nodes. Expect node error 506 to
now be reported and follow the service
procedures for that error.
Possible Cause-FRUs or other:
v None
506 No enclosure identity and no node state
on partner
Explanation: The enclosure vital product data
indicates that the enclosure chassis has been replaced.
There is no cluster state information on the other node
canister in the enclosure (the partner canister), so both
node canisters from the original enclosure have not
been moved to this one.
User response: Follow troubleshooting procedures to
relocate nodes to the correct location:
1. Review the saved location information of the node
canister and why the second node canister from the
original enclosure was not moved into this
enclosure.
2. If you are sure that this node canister came from
the enclosure that is being replaced, and the original
partner canister is available, use the hardware
remove and replace node canister procedure to
