Starting and Stopping the System

Starting and Stopping the System

You can start, shut down, and restart all storage nodes in the OceanStor 9000 cluster.

Prerequisites

If the BMC network and management network have access restrictions (inaccessible due to physical isolation or firewalls), starting the system on all storage nodes in the cluster using DeviceManager, CLI, or SNMP interfaces will fail.

Ensure that the passwords of iBMC account admin of all storage nodes in the cluster are the same so that you can use the Start System function. Otherwise, you can only power on each node one by one.

  • For P12E, P25E, P36E, and C36E nodes, after cluster deployment and capacity expansion, log in to the CLI and run the change system ipmi_password admin command to add iBMC account admin and set its password.
  • After the system is delivered, you can also run the change system ipmi_password admin command to change the password of iBMC account admin. To reduce security risks, change the password periodically.

For details about how to log in to the CLI, see Appendix A Common Operations > Logging In to the CLI.

Context

Table 13-1 defines system status. Figure 13-1 shows how system status changes.

Table 13-1  Definitions of system status

Status

Description

Starting

The system is being started and cannot provide services.

Normal

The system provides services correctly, and no nodes or disks are faulty.

Degraded

The system provides services correctly but the service reliability is compromised, for example, system status changes to degrade when some nodes or disks are faulty and the number of failed nodes or disks does not exceed the threshold specified in the data protection level.

Partially Damaged

The system can provide services but is partially faulty. Some files in the system are inaccessible.

Faulty

The system cannot provide services.

Upgrading

The system is being upgraded.

Stopping

The system is being powered off. No new service requests are received. After existing service requests are processed, all services and nodes are stopped.

Stopped

The system is powered off.

Procedure

  • Starting the system
    1. Press the Power buttons on the front panels of more than half of the storage nodes (including any two of the three storage nodes in the bottom of the base cabinet) in the cluster.

      Perform this operation before logging in to DeviceManager.

    2. Wait approximately 5 minutes and log in to DeviceManager.
    3. Choose Settings > Start System.

      • For a cluster consisting of P12E, P25E, P36E, and C36E nodes, enter the password of iBMC account admin as prompted.
      • For a cluster consisting of P12, P25, P36, and C36 nodes, enter the password of IPMI account admin as prompted (default password: Admin@storage).
      • For a cluster consisting of C72 nodes cannot be started remotely.

  • Shutting down the system
    1. Log in to DeviceManager.
    2. Choose Settings > Power Off Device.
    3. Carefully read the content of the dialog box, enter the password of the current user and select I have read and understood the consequences associated with performing this operation, then click OK.
  • Restarting the system

    NOTE:

    Nodes in the system are restarted in certain sequence and at different speeds. As a result, the system may display alarms indicating that a node has logged out. The alarm disappears when the node is started.

    1. Log in to DeviceManager.
    2. Choose Settings > Restart Device.
    3. Carefully read the content of the dialog box, enter the password of the current user and select I have read and understood the consequences associated with performing this operation, then click OK.
