Faulty Operating System of the Server

Faulty Operating System of the Server

Symptom

The operating system of the server is faulty. As a result, you cannot log in to the server.
NOTE:

If the server is a DR server of a non-control cluster or a converged storage and DR server, contact Huawei technical support engineers.

Possible Causes

  • The operating system of the server is faulty.
  • The server hardware is faulty.

Fault Diagnosis

None

Procedure

    Install the server OS and hardware drives.

    1. Perform operations based on the FusionStorage deployment scenario.

      • FusionSphere scenario: Restore the OS of the server by following the instructions provided in section "Host OS Faults" in FusionSphere Product Documentation.

        To obtain FusionSphere Product Documentation, visit the following website:

        For enterprise users, log in to http://support.huawei.com/enterprise. For carrier users, log in to http://support.huawei.com. Enter FusionSphere in the search box, and click the path displayed below the search box to enter the product page.

      • VMware vSphere virtualization deployment: For details about how to install an OS for a server and a computing server that is deployed separately, see the VMware vSphere help document. For details about how to install an OS for a storage server, see section "Installing the Operating System of a Storage Node" in FusionStorage Block Storage Service Software Installation Guide.

      • Microsoft Hyper-V virtualization deployment: For the integrated deployment server and the computing server that is deployed separately, install the OS for the server by referring to the help document of the Microsoft Hyper-V. For details about how to install an OS on a storage server, see Installing Operating Systems for Storage Nodes in FusionStorage Block Storage Service Software Installation Guide.

      • Physical deployment: Install the OS on the server by referring to Installation Process (Physical Servers) > Installing an OS in FusionStorage Block Storage Service Software Installation Guide. The management IP address and storage IP address must be the same as those of the faulty node.

    2. Install the hardware device driver. For details about hardware device driver requirements of FusionStorage, see the Installation Preparations in Installation Process of FusionStorage Block Storage Service Software Installation Guide.
    3. (Optional) If the FSM node is deployed on the server, restore the FSM node by following the instructions provided in "Single FSM Node Fault."

      Determine the server status.

      1. Perform the required operation based on the server type and status.

        • To control the servers in the cluster, go to 21.
        • If the server is a compute server of a non-control cluster, go to 9.
        • If the server is a storage server of a non-control cluster or a converged storage and compute server and the storage resources on the server have been removed from the storage pool, go to 5.
        • If the server is a storage server of a non-control cluster or a converged storage and compute server and the storage resources on the server are not removed from the storage pool (displayed as faulty on the disk topology page), go to 21.

      Reducing the Storage Pool Capacity

      This step is required only for a storage server or a converged storage and compute server.

      1. On the FusionStorage Block Self-Maintenance Platform, choose Resource Pool > Storage Pools.

        The Storage Pools page is displayed.

      2. Select the storage pool where the faulty server resides and click Capacity Reduction.

        The Capacity Reduction page is displayed.

      3. Select the server whose capacity you want to reduce and click OK.

        After the server is successfully deleted, the Storage Pools page is displayed, and the FusionStorage Block storage pool capacity is reduced.

      4. (Optional) If the server has been added to multiple storage pools, perform 6 to 7 to remove the server from other storage pools.

      Install the FSA node for the server using the command-line interface (CLI).

      1. Log in to the active FSM node as user dsware.

        If the public and private keys are used to authenticate the login, perform the operations based on Using PuTTY to Log In to a Node in Key Pair Authentication Mode in the FusionStorage Block Storage Service Administrator Guide.

      2. Run the following command to install the FSA component on the server:

        • Use the account and password to log in to the system.
          NOTE:

          Since the system has been hardened, you need to enter the username and password for login authentication after running the dswareTool command of FusionStorage Block. The default username is cmdadmin, and its default password is IaaS@PORTAL-CLOUD9!.

          The system supports authentication using environment variables so that you do not need to repeatedly enter the username and password for authentication each time you run the dswareTool command. For details, see Authentication Using Environment Variables in the FusionStorage Block Storage Service Software Installation Guide.

          sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackage -ip Management IP address of the node where the storage device resides after replacement -method install -rpmName DSwareAgent.tar.gz -force true

          For example: sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackage -ip 192.168.12.21 -method install -rpmName DSwareAgent.tar.gz -force true

          1. Enter the user name and password of the server as prompted.

            If you log in to the server as user root, enter user name root and its password as prompted.

            If you log in to the server as a non-root user, enter the user name, password, and the password of user root as prompted.

          2. Enter the user name and password for authentication as prompted.
        • Use public and private key authentication to log in.

          sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackageByPrivateKey -ip Management IP address of the node where the new storage device resides -method install -rpmName DSwareAgent.tar.gz -force true -privateKey Private key file

          For example, sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackageByPrivateKey -ip 192.168.36.21 -method install -rpmName DSwareAgent.tar.gz -force true -privateKey /home/omm/.ssh/id_rsa

      Expanding a Storage Pool

      This step is required only for a storage server or a computing-storage converged server.

      1. On the FusionStorage Block Self-Maintenance Platform, choose Resource Pool > Storage Pools.

        The Storage Pools page is displayed.

      2. Select the storage pool where the faulty server resides and click Capacity Expansion.

        The Capacity Expansion page is displayed.

      3. Select Add Storage Server.
      4. Click Add Server.

        A dialog box is displayed.

      5. In the Main Storage Type and Cache Type areas, set the main storage and cache information for the server to be added.

        The main storage type and cache type of the server to be added must be the same as those of the original storage pool. You need to select the slot information of the main storage and cache.

        Use either of the following method:
        • Batch Selection: Enter the slot information or quantity. After the server is added, the corresponding slot is automatically selected. The disk is used as the main storage or cache.
        • Manual Select: After the server is added, you need to manually select the corresponding main storage and cache in the server information.

      6. In the server list, select the server that can be used for capacity expansion.
      7. Click OK.

        The Capacity Expansion page is displayed.

      8. Click Capacity Expansion.

        The Storage Pools page is displayed, and the FusionStorage Block storage capacity expansion is complete.

      Restoring a Block Storage Client

      You need to perform this operation on only compute servers, converged storage and compute servers, and DR servers.

      1. Log in to the active FSM node as user dsware.

        If the public and private keys are used to authenticate the login, perform the operations based on Using PuTTY to Log In to a Node in Key Pair Authentication Mode in the FusionStorage Block Storage Service Administrator Guide.

      2. Run the following commands in sequence to restore block storage clients on DR nodes.

        cd /opt/dsware/client/bin

        sh dswareTool.sh --op createDSwareClient -ip Management IP address of the node to be restored -nodetype typeflag

        When the node of the to-be-recovered block client is a DR server, the value of typeflag is 1. Otherwise, the value of typeflag is 0.

        After the operation is complete, no further action is required.

      Install the FSA node for the server using the command-line interface (CLI).

      1. Log in to the active FSM node as user dsware.

        If the public and private keys are used to authenticate the login, perform the operations based on Using PuTTY to Log In to a Node in Key Pair Authentication Mode in the FusionStorage Block Storage Service Administrator Guide.

      2. Run the following command to install the FSA component on the server:

        • Use the account and password to log in to the system.
          NOTE:

          Since the system has been hardened, you need to enter the username and password for login authentication after running the dswareTool command of FusionStorage Block. The default username is cmdadmin, and its default password is IaaS@PORTAL-CLOUD9!.

          The system supports authentication using environment variables so that you do not need to repeatedly enter the username and password for authentication each time you run the dswareTool command. For details, see Authentication Using Environment Variables in the FusionStorage Block Storage Service Software Installation Guide.

          sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackage -ip Management IP address of the node where the storage device resides after replacement -method install -rpmName DSwareAgent.tar.gz -force true

          For example: sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackage -ip 192.168.12.21 -method install -rpmName DSwareAgent.tar.gz -force true

          1. Enter the user name and password of the server as prompted.

            If you log in to the server as user root, enter user name root and its password as prompted.

            If you log in to the server as a non-root user, enter the user name, password, and the password of user root as prompted.

          2. Enter the user name and password for authentication as prompted.
        • Use public and private key authentication to log in.

          sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackageByPrivateKey -ip Management IP address of the node where the new storage device resides -method install -rpmName DSwareAgent.tar.gz -force true -privateKey Private key file

          For example, sh /opt/dsware/client/bin/dswareTool.sh --op rpmPackageByPrivateKey -ip 192.168.36.21 -method install -rpmName DSwareAgent.tar.gz -force true -privateKey /home/omm/.ssh/id_rsa

      Restoring Storage Resources

      1. In the CLI of the active FSM node you have logged in to as user dsware, run the required command to restore storage resources:

        • Non-control cluster nodes: sh /opt/dsware/client/bin/dswareTool.sh --op restoreStorageNode -ip Management IP address of the node -p Storage pool ID

          For example: sh /opt/dsware/client/bin/dswareTool.sh --op restoreStorageNode -ip 192.168.60.31 -p 0

          This command is a high-risk operation. If you want to continue, enter y as prompted.

          Enter the user name and password of the server as prompted.
