Defining minidisk attachments in a server complex

By setting the minidisks properties, you can define one or more minidisk attachments for the Linux guest systems in the server complex.

A minidisk is identified by its owner (a z/VM user ID) and the owner's virtual number. You provide the desired mount point for each minidisk and the configuration occurs both on the z/VM and at the Linux level.

Complete the following steps to edit the minidisks configuration domain:

  1. If it is not started already, start the Server Complexes task for the z/VM system you want to work with.
  2. Select the server complex where you want to specify minidisk attachments.
  3. Click ActionEdit Properties to open the Server Complex Properties window and click the Minidisks tab to display the Minidisks page.
  4. Choose whether the configuration target is the whole server complex or a specific tier.
  5. If you chose the Specific tier radio button, choose the target tier.
  6. Click Add to add a minidisk to the Minidisk list. In the Minidisk Properties window, you can enter the properties of the new minidisk.
    1. In the Mount point field, type the Linux mount point for the minidisk.
    2. In the VDEV field, type the virtual device number at the Linux guest system.
    3. In the Owner VDEV field, type the virtual device number of the minidisk owner.
    4. In the Owner userid field, type the VM user ID of the minidisk owner.
    5. In the Access mode field: If you select the Read Only check box, a z/VM RR mode and a Linux ro mount are used. If you clear this check box, a z/VM MR mode and a Linux rw mount are used.
    6. In the Exit Policy field: If you select the Detached on exit check box, the minidisk is detached when you remove the Linux guest system or the minidisk from the server complex.
    7. Click OK to save the minidisk with these properties. The minidisk is added to the Minidisk list.
  7. (Optional) You can select a line in the Minidisk list and click Edit (or alternatively, double-click the line) to display or edit the properties of that minidisk.
  8. (Optional) Select a line in the Minidisk list and click Remove to remove a mindisk from the list.
  9. Click OK to apply the modified settings to the Linux guest systems currently in the server complex. If you modified settings in any of the other domains (except for the Scripts domain), these are also applied to the Linux guest systems in the server complex.
  10. In the Guest Selection window, choose the Linux guest systems on which to apply the reconfiguration, and click Yes.
  11. Before applying the modified properties, the Server Complexes task runs a consistency check against the old properties. The Progress Indication window shows the progress of the action. If there is an inconsistency, you are given a choice whether to proceed or stop. Stopping saves the new properties but doesn't apply the configuration. After the operation is completed, click Close to close the Progress Indication window.
Note: At any time, with or without changing the property values, you can open this page and click the Apply button to directly apply the properties of this domain to Linux guest systems in the server complex. For more information, see Directly applying server complex properties in a single domain.
