CPU core number exceeded

CPU core number exceeded

The article describes and provides the solution to the problem of platform locking when the number of CPU cores in the platform exceeds the allowable license limit.

Description

VMmanager licensing takes into account the number of physical CPU cores in use on cluster nodes. If the number of physical cores in the platform exceeds the allowed limit of cores in the license, the platform will be locked. A pop-up banner will appear in the interface reading The number of cores has exceeded the allowed limits. The platform has been blocked.

Solution

To unlock the platform:

  1. Connect to the node server via SSH.

  2. Check the number of cores:

    dmidecode --type processor | grep -i "core count" | grep -Eo "[0-9]+?"

    The response to the command will be an integer.
    The command should be executed on each platform node and the result summarized.

  3. Check the number of cores for your license in your client area. Enter Products/Services → Licenses → select a license → click Edit → Add-ons → Total CPU Limit.
  4. If the actual value of cores obtained in step 2 exceeds the Total CPU Limit for the license, perform one of these actions:

    • increase the number of cores for the license in your client area:

      1. Enter Products/Services → Licenses → select a license → click Edit → Add-ons → Total CPU Limit.
      2. Move the slider to the required number of cores.

      3. If necessary, pay for extra cores.

        VMmanager Infrastructure users can purchase an extra package to increase the available CPU cores. Once purchased, the package must be activated according to the instructions.
    • reduce the actual number of cores in your infrastructure.

  5. Update the license information: go to → System information → Update the license.

    Note
    There may be a slight delay in synchronizing the platform with the information on the licensing server. Therefore, it is recommended to update the license in the interface 5-10 minutes after changing the number of cores.

If the actual value of cores obtained in step 2 does not exceed the Total CPU Limit for the license, contact ISPsystem technical support to identify problems with the license.
