2. Example: add drive linking to an existing volume

The following example shows how to add drive linking to a volume with the EVMS GUI, Ncurses, and CLI interfaces.

Example 17.1. Add drive linking to an existing volume

The following sections show how to add a drive link to volume /dev/evms/vol and call the drive link "DL."


NOTE

Drive linking can be done only on EVMS volumes; therefore, /dev/evms/vol must be converted to an EVMS volume if it is not already.

2.1. Using the EVMS GUI

Follow these steps to add a drive link to the volume with the EVMS GUI:

  1. Select Actions → Add → Feature to Volume.

  2. Select /dev/evms/vol

  3. Click Next.

  4. Select Drive Linking Feature.

  5. Click Next.

  6. Type DL in the Name Field.

  7. Click Add.

Alternatively, you can perform some of the steps to add a drive link with the GUI context sensitive menu:

  1. From the Volumes tab, right click /dev/evms/vol.

  2. Click Add feature...

  3. Continue adding the drive link beginning with step 3 of the GUI instructions.

2.2. Using Ncurses

Follow these steps to add a drive link to a volume with Ncurses:

  1. Select Actions → Add → Feature to Volume.

  2. Select /dev/evms/vol.

  3. Activate Next.

  4. Select Drive Linking Feature.

  5. Activate Next.

  6. Press Spacebar to edit the Name field.

  7. At the "::" prompt enter DL.

  8. Press Enter.

  9. Activate Add.

Alternatively, you can perform some of the steps to add a drive link with the context sensitive menu:

  1. From the Volumes view, press Enter on /dev/evms/vol.

  2. Activate the Add feature menu item.

  3. Continue adding the drive link beginning with step 3 of the Ncurses instructions.

2.3. Using the CLI

Use the add feature to add a feature to an existing volume. Specify the command name followed by a colon, followed by any options and the volume to operate on. To determine the options for a given feature, use the following query: 

query: plugins, plugin=DriveLink, list options

The option names and descriptions are listed to help you construct your command. For our example, the command would look like the following: 

add feature: DriveLink={ Name="DL }, /dev/evms/vol
