Configuring Linux Infrastructure VMs
Scenario

This section describes how to configure Linux infrastructure VMs, including:

  • Enable automatic recovery for infrastructure VMs.
  • Install the OS.
  • Install the Driver Tools.
Data

For required parameters, see specific procedures.

Software

FusionAccess_Euler_Installer_V100R006C20SPC103.iso

Procedure
Setting the automatic recovery attribute for Linux infrastructure VMs
NOTE:

If a storage network exception occurs, Linux VMs may fail to be recovered automatically. Perform this operation to ensure system reliability. Windows VMs can be recovered automatically when a storage network exception occurs. Therefore, this operation is unnecessary.

  1. Use PuTTY to log in to the active VRM node using the floating VRM IP address. The login account is gandalf and the default password is IaaS@OS-CLOUD9!.
  2. Run the following command to switch to user root. The default password is IaaS@OS-CLOUD8!.

    su - root

  3. Run the following command to disable user logout upon system timeout:

    TMOUT=0

  4. Run the following command for each infrastructure VM:

    sh /opt/galax/vrm/tomcat/script/modifyRecover.sh vmId true

    vmId is the VM ID.

    You can get the VM ID on the FusionCompute page, as shown in Figure 2-4.

    Figure 2-4 VM ID

  1. Run the following command to restart the VRM process:

    service vrmd restart

  2. In the navigation tree on the left, click to enter the Resource Pools page.
  3. On the VM tab, enter the search criteria and search the VM to be stopped.
  4. Select the VM to be stopped and select a stop mode.

    • To safely stop a VM, choose More > Power > Stop in the Operation column.
    • To forcibly stop a VM, choose More > Power > Forcibly Stop in the Operation column.
      NOTE:
      1. Safely stop: Stops a VM by stopping its operating system (OS). This mode automatically saves data and is secure. However, it takes a long time for the VM to stop in this mode. Therefore, select this mode when the VM runs properly.
      2. Forcibly stop: Stops a VM forcibly. This operation may damage data in the VM disk. Therefore, select this mode only when the VM OS is abnormal and the VM cannot be safely stopped.

  5. Locate the row that contains the target VM and click Start in the Operation column to start the VM.
