Authorizing Repair of a Lite Server

Description

When a Lite Server requires hardware maintenance due to an unrecoverable fault, a scheduled event will be pushed to the Event Center on the console. In the event center, you can view the event information, type, status, and description. You can also authorize Huawei technical support to perform O&M on the faulty node or redeploy the node.

Table 1 Event operation execution conditions

Event Type

Event Status

Supported Operations

Applicable Resource Type

Description

System maintenance

Authorization Pending

Authorization and redeployment

Snt9b

System maintenance is to authorize Huawei technical support to systematically maintain the faulty node.

Local disk recovery

Authorization Pending

Authorization and redeployment

Snt9b

Local disk recovery is to authorize Huawei technical support to maintain the faulty local disk.

After the local disk is recovered, reset the nodes or log in to the nodes to restore the node partition.

WARNING:

After authorization, recovering the local disk will cause local supernode disk loss. Therefore, migrate services and back up data before authorization.

Supernode maintenance

Authorization Pending

Authorization

Snt9b23

Supernode maintenance is to authorize Huawei technical support to recover faulty nodes by manually repairing or replacing components.

Supernode redeployment

Authorization Pending

Authorization

Snt9b23

Supernode redeployment is to authorize the Huawei O&M system to recover faulty nodes by automatically replacing nodes. After the recovery, the node name, node ID, and IP address remain unchanged except the physical device information.

Supernode local disk recovery

Authorization Pending

Authorization

Snt9b23

Supernode local disk recovery is to authorize Huawei technical support to restore the local disk of the supernode.

After the local disk is recovered, reset the nodes or log in to the nodes to restore the node partition.

WARNING:

After authorization, recovering the local disk will cause local supernode disk loss. Therefore, migrate services and back up data before authorization.
  • Authorization: Authorize Huawei technical support to repair the hardware of the faulty node one by one, which takes a long time.
  • Redeployment: Authorize Huawei technical support to replace the faulty node with a new one, which is fast, but local disk data will be lost after the redeployment. Exercise caution. Moreover, migrate services and back up data before redeployment.

Constraints

  • Only Snt9b and Snt9b23 supernodes support hardware maintenance through scheduled events.
  • Redeployment of supernodes must be performed within physical supernodes. If there are 48 supernodes, redeployment is not supported and the authorization button becomes unavailable.
  • If the planned event does not meet the requirements listed in Table 1, the Authorize button becomes unavailable.
  • Before authorizing a supernode redeployment event, you need to stop the Lite Server instance on the Lite Servers page. Otherwise, the authorization fails. After the event is executed, restart the server instance.
  • Authorizing a node will affect services running on it. The authorization operation can be performed only when the event type is Supernode Redeployment and the node is shut down.
  • After the local node disk and supernode disk are restored, the local disk data will be lost. Therefore, migrate services and backup data before authorization. After the local disk is restored, log in to the Lite Server to partition the local disk.

Viewing Scheduled Events

Log in to the ModelArts console. In the navigation pane on the left, choose Resource Management > Auxiliary Tools > Event Center (old console: Resource Management > Event Center). On the Event Center page, you can view event details. By default, events in the Authorization Pending, Authorized, and Executing states are displayed. You can remove the filter criteria to view events in all states.

Event Status
  • Authorization Pending: Querying. The event is to be authorized. After authorization, the status changes to Authorized.
  • Authorized: The O&M task is planned to be executed but has not started. After the task starts, the task enters the Executing state.
  • Executing: The O&M task is being executed.
  • Completed: The O&M task has been executed.
  • Failed: The O&M task fails to be executed.
  • Canceled: The system cancels the O&M task.

Operation

Authorize: Authorizing a node will affect services running on it. The authorization operation can be performed only when the event type is Supernode Redeployment and the node is shut down.

NOTE:

Redeployment of supernodes must be performed within physical supernodes. If there are 48 supernodes, redeployment is not supported and the authorization button becomes unavailable.

Authorization Operations

If the faulty nodes meet the requirements listed in Table 1, you can authorize Huawei technical support to perform O&M on the faulty nodes.

To do so, log in to the ModelArts console. In the navigation pane on the left, choose Resource Management > Auxiliary Tools > Event Center (old console: Resource Management > Event Center). Locate the target node and click Authorize in the Operation column. In the displayed dialog box, click OK. The following steps describe how to authorize Huawei technical support to perform O&M on a supernode.

  1. Log in to the ModelArts console. In the navigation pane on the left, choose Resource Management > Auxiliary Tools > Event Center (old console: Resource Management > Event Center). On the displayed page, view the supernode maintenance event and perform authorization.
  2. The supernode maintenance event enters the Authorized state.
  3. After the supernode is repaired, the event status is Completed. In this case, the node is available.

    After the O&M, Huawei technical support will disable the authorization. You do not need to perform further operations.

    For local disk or supernode disk restoration, you need to log in to the Lite Server and partition the local disk.

Redeployment Operations

After the redeployment, the data on the local disk will be lost. Exercise caution. Before redeployment, migrate services and back up data, and preprocess the local disk before instance redeployment. For details, see Preprocessing for Instance Redeployment.

If the faulty node meets the redeployment conditions listed in Table 1, you can go to the Resource Management > Auxiliary Tools > Event Center (old console: Resource Management > Event Center) page, locate the target node, and click Redeploy in the Operation column. In the dialog box that is displayed, enter YES and click OK to complete the redeployment authorization.

If the planned event does not meet the requirements listed in Table 2, the Redeploy button becomes unavailable.

After the O&M, Huawei technical support will disable the authorization. You do not need to perform further operations.
