The system recovery procedure works only when
all nodes are in candidate status. If there are any nodes that display error code 550 or error code
578, you must remove their data.
About this task
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 with an error 550 or 578, follow this procedure using the service
assistant:
Procedure
- 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, configure the service address
in one of the following ways:- On SAN Volume Controller models 2145-CG8 and
2145-CF8 nodes, use the front panel
menu to configure a service address on the node.
- On SAN Volume Controller
2145-DH8 nodes, use the technician port to
connect to the service assistant and configure a service address on the node.
- 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.
Results
When all nodes display a status of candidate and all error
conditions are None, you can run the recovery
procedure.
