Restarting the storage cluster

[On the controller node] Restart the storage cluster.

CLI: storage_shutdown

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
--reboot true
--user <user-with-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.

[On the controller node] Obtain a list of event logs by running the CLI (event_log_list), and then verify that event log KARS08100-I is output indicating that the storage cluster startup completed.

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>
--severity Info

You will be prompted to enter the password after running the command. Ask the system administrator to enter the password.

CAUTION:

If event log KARS08100-I (startup of the cluster was completed) is not output after 265 minutes have passed since the storage cluster restart operation, contact the Hitachi design team.

Note:

The KARS08100-I event log is output each time the storage cluster is started. Check the output time to verify that the event log is output by performing this procedure.

[On the controller node] Use the following procedure to verify that the storage cluster is started.

CAUTION:

"Alerting" might be shown for statusSummary. This is temporary. Wait for approximately two minutes, and then run the command again.

Obtain the status of the storage cluster by running the following CLI command: storage_show. Verify that the status is "Ready."

If the status of the storage cluster does not change to "Ready", contact the Hitachi design team.

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.

[On the controller node] Verify that the storage cluster is operating normally.

If there is a problem, contact the Hitachi design team.

Obtain each health status by running the following CLI command: health_status_show. Verify that the health status of each resource is "Normal."
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 <any-user>
- --host <IP-address-obtained-in-step-1-in-Restoring>
(Execution example)
```
hsds --ignore_certificate_errors --user <any-user> \
--host <IP-address-obtained-in-step-1-in-Restoring> \
health_status_show
```
You will be prompted to enter the password after running the command. Ask the system administrator to enter the password.

CAUTION:
- When the health status of the volume is "Alerting", verify that the event log KARS06132-C is output in the next step 4-b. If the event log is not output, contact the Hitachi design team.
- When the health status of the license is "Alerting", see Managing your license in the VSP One SDS Block and SDS Cloud System Administration to perform necessary tasks after completing the procedures shown in Restore workflow.
Obtain a list of event logs by running the following CLI command: event_log_list. Verify that no event logs for each error type are output other than the following.
- KARS03166-E
- KARS05010-E
- KARS06132-C
- KARS06201-E
- KARS06220-C
- KARS06221-C
- KARS06222-C
- KARS07290-C
- KARS16025-E
- KARS16119-E
- KARS25001-E
CAUTION:

Other event logs might be output depending on how restore operations are done. In that case, contact the Hitachi design team.

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>
- --severity_ge Error
(Execution example)
```
hsds --ignore_certificate_errors --user \
<user-with-Security-or-Storage-or-Monitor-or-Service-role> \
--host <IP-address-obtained-in-step-1-in-Restoring> \
event_log_list --severity_ge Error
