Removing system information for node canisters with error
code 550 or error code 578 using the service assistant
The system recovery procedure works only when all node canisters are in
candidate status. If there are any node canisters that display error code 550 or error
code 578, you must remove their data.
Before performing this task, ensure that you have read the introductory
information in the overall recover system procedure.
To remove system information from a node canister with an error 550 or 578,
follow this procedure using the service assistant:
1. Point your browser to the service IP address of one of the nodes, for example,
https://node_service_ip_address/service/.
If you do not know the IP address or if it has not been configured, you must
assign an IP address using the initialization tool.
2. Log on to the service assistant.
3. Select Manage System .
4. Click Remove System Data .
5. Confirm that you want to remove the system data when prompted.
6. Remove the system data for the other nodes that display a 550 or a 578 error.
All nodes previously in this system must have a node status of
Candidate
and
have no errors listed against them.
7.
Resolve any hardware errors until the error condition for all nodes in the
system is
None .
8. Ensure that all nodes in the system display a status of candidate.
When all nodes display a status of candidate and all error conditions are None ,
you can run the recovery procedure.
Performing system recovery using the service assistant
Start recovery when all node canisters that were members of the system are online
and have candidate status. Use the service assistant to verify the status. If any
nodes display error code
550
or
578
, remove their system data to place them into
candidate status. Do not run the recovery procedure on different node canisters in
the same system.
All node canisters must be at the original level of software, prior to the system
failure. If any node canisters were modified or replaced, use the service assistant to
verify the levels of software, and where necessary, to upgrade or downgrade the
level of software.
Attention: This service action has serious implications if not performed properly.
If at any time an error is encountered not covered by this procedure, stop and call
IBM Support.
Note: The web browser must not block pop-up windows, otherwise progress
windows cannot open.
