Note: The cables must be inserted back into the same ports from which they
were removed on the old enclosure; otherwise, the system cannot function
properly.

the repair identification (RID) tag that is supplied. Attach the tag to the left
flange at the back of the enclosure.
units. The node canisters boot up. The fault LEDs are on because the new
enclosure has not been set with the identity of the old enclosure. The node
canisters log node error 504, reporting that they are in the wrong location. In
the system event log these appear with an error code of 1192.
machine type and model, serial number, and WWNNs that are stored in the
enclosure. If you have replaced a node canister, connect to the canister that
has not been replaced. You can connect using the previous service address.
However, it is not always possible to maintain this address. If you cannot
connect through the original service address, attempt to connect using the
default service address. If you still cannot access the system, see "Problem:
Cannot connect to the service assistant" on page 245.
machine type and model, and Update the serial number. Do not update the
system ID. Use the node copy data for each of the values. Check that these
values match the values that you recorded in step 1 on page 340. If you were
not able to record the values, use the node copy values only if none of them
have all zeroes as their value. If any of the node copy values are all zeroes,
connect the service assistant to the other node canister and configure the
enclosure there. If you still do not have a full set of values, contact IBM
support.
Important: Step 30 writes the enclosure identity into the replacement
midplane. The replacement midplane cannot be used as a replacement part for
a different enclosure after step 30 is completed.
Note: There are situations where the canisters restart and report critical node
error 508. If the node canisters fail to become active after they restart when
the enclosure is updated, check their status by using the service assistant. If
both node canisters show critical node error 508, use the service assistant to
restart the nodes. For any other node error, see "Procedure: Fixing node
errors" on page 271. To restart a node from the service assistant, perform the
following steps:
a. Log on to the service assistant.
b. From the home page, select the node that you want to restart from the
Changed Node List.
c. Select Actions > Restart.
The system starts and can handle I/O requests from the host systems.
