# Listing, Selecting, and Reviewing Kernel Definitions

You can list, select, and review Kernel definitions that are managed by SMH. These definitions are listed in two areas:

- The permanent definition for a Kernel is listed in the Servers section of the Entire Net-Work Server SMH administration area. You can maintain the definitions in this area and the changes you make are permanent (until the next time you make a change).

- The dynamic definition for a started Kernel is listed in the Kernels section of the Entire Net-Work Server SMH administration area. Statistics for the active Kernel as well as some of its parameters can be reviewed and maintained in this area. Any maintenance performed to parameters in the dynamic definition are preserved only temporarily. Once the Kernel is stopped, the changes made to the dynamic definition are lost and, if the Kernel is restarted, it starts using its permanent definition. Therefore, if you want to change the definition of a Kernel so it remains the same every time you start it, be sure to make the change to the permanent definition, not the dynamic definition.

  Note
  A Kernel must be started in the Servers section of the Entire Net-Work Server SMH administration area before you can see it in the Kernels section.

## Listing, Selecting, and Reviewing Permanent Definitions

To list and review the permanent Kernel definitions managed by SMH:

Make sure you have accessed the System Management Hub.

1. Select the name of the managed host on which Entire Net-Work Server is installed.

2. Expand the tree-view frame for the managed host by clicking on the plus sign (+) to the left of its name.

3. Select "Entire Net-Work Server" in the tree-view under the managed host.

   The Entire Net-Work Server administration area of the System Management Hub becomes available to you.

4. Expand Servers in tree-view, by clicking on the plus sign (+) to the left of its label.

   The list of installed servers appears.

5. Expand the name of the server in the server list in tree-view, by clicking on the plus sign (+) to the left of its label.

   A list of Kernels defined to the server appears.

6. Select and expand the Kernel definition you want from the list.

   The permanent Kernel definition section becomes available in tree-view.

   The following commands are available for each Kernel:
