Registering spare node information

Procedures in this section only apply to the case in which you prepare spare nodes to a storage cluster for which restoring configuration completes.

CAUTION:

Server models other than those described in the VSP One SDS Block Bare Metal Hardware Compatibility Reference do not support the spare node function, and therefore might not allow for spare node switchover. For details about server models that support spare node switchover, see the VSP One SDS Block Bare Metal Hardware Compatibility Reference.

This section describes how to register spare node information.

Ask a system administrator about the ID of the fault domain for which you register spare nodes.

Confirm the ID of the fault domain for which you register spare nodes.

CLI: fault_domain_list

If you receive no response after waiting approximately 1 minute, stop the CLI command forcibly with Ctrl+C, and then retry the operation. If the problem persists, contact the Hitachi design team.

The required parameters are as follows:
- --ignore_certificate_errors
- --user <user-with-Security-or-Storage-or-Monitor-or-Service-role>
- --host <IP-address-obtained-in-step-1-in-Restoring>
You will be prompted to enter the password after running the command. Ask the system administrator to enter the password.
Register spare node information.

CLI: spare_node_create

If you receive no response after waiting approximately 1 minute, stop the CLI command forcibly with Ctrl+C, and then retry the operation. If the problem persists, contact the Hitachi design team.

The required parameters are as follows:
- --ignore_certificate_errors
- --user <user-with-Service-role>
- --host <IP-address-obtained-in-step-1-in-Restoring>
- --fault_domain_id <ID-of-fault-domain-confirmed-in-step-1>
- --controlPortIpv4Address <IP-address-of-control-ports-of-spare-nodes>
- --bmc_name <BMC-connection-destination-IP-address-of-storage-nodes>
- --bmc_user <username-for-BMC-connection-of-spare-nodes>
Ask a system administrator to enter the password of the user having the Service role and the BMC-connection-destination address of spare nodes, the username for BMC connection of spare nodes, and the password for BMC connection of spare nodes.

Verify the job ID displayed after running the command.
Verify the state of the job.

Run the following command with the job ID specified.

CLI: job_show

If you receive no response after waiting approximately 1 minute, stop the CLI command forcibly with Ctrl+C, and then retry the operation. If the problem persists, contact the Hitachi design team.

The required parameters are as follows:
- --ignore_certificate_errors
- --user <user-with-Security-or-Storage-or-Monitor-or-Service-role>
- --host <IP-address-obtained-in-step-1-in-Restoring>
- --job_id <job-ID-confirmed-in-step-2>
You will be prompted to enter the password after running the command. Ask the system administrator to enter the password.

If the job state is "Succeeded", the job is completed.
Obtain a list of spare node information to verify that the spare node information was registered.

CLI: spare_node_list

If you receive no response after waiting approximately 1 minute, stop the CLI command forcibly with Ctrl+C, and then retry the operation. If the problem persists, contact the Hitachi design team.

The required parameters are as follows:
- --ignore_certificate_errors
- --user <user-with-Service-role>
- --host <IP-address-obtained-in-step-1-in-Restoring>
