The system recovery procedure
works only when all node canisters are in candidate status. Ensure
that the service assistant displays all of the node canisters with
the 550 error code. The 550 error code is the expected node error
when more than half of the nodes in the system are missing or when
the active quorum disk cannot be found. If the service assistant displays
any node canisters with error codes 550 or 578 and all the recommended
actions have been completed on these nodes, you must remove their
system 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:
- Point your browser to the service IP address
of one of the nodes, for example, https://node_service_ip_address/service/.
For Lenovo Storage V7000 Gen1 , if you do not know the IP address or if it has not been
configured, you must assign an IP address with the USB flash drive
method. For Lenovo Storage V7000 Gen2, if you do not know the IP address or if it has not been
configured, you must assign an IP address with the technician port
method. See the initialization tool interface topic for more information.
- Log on to the service assistant.
- Select Manage System.
- Click Remove System
Data.
- Confirm that you want to remove
the system data when prompted.
- 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.
- Resolve any hardware errors until
the error condition for all nodes in the system is None.
- 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.
