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:
- If it is not started already, start the Server Complexes
task for the z/VM system you want to work with.
- Select the server complex where you want to specify minidisk attachments.
- Click Action → Edit Properties to open the Server
Complex Properties window and click the Minidisks tab to display the
Minidisks page.
- Choose whether the configuration target is the whole server complex
or a specific tier.
- If you chose the Specific tier radio button, choose the
target tier.
- Click Add to add a minidisk to the Minidisk list.
In the Minidisk Properties window, you can enter the properties of the new
minidisk.
- In the Mount point field, type the Linux mount point
for the minidisk.
- In the VDEV field, type the virtual device number at
the Linux guest system.
- In the Owner VDEV field, type the virtual device number
of the minidisk owner.
- In the Owner userid field, type the VM user ID of the
minidisk owner.
- 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.
- 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.
- Click OK to save the minidisk with these properties.
The minidisk is added to the Minidisk list.
- (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.
- (Optional) Select a line in the Minidisk list and click Remove to
remove a mindisk from the list.
- 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.
- In the Guest Selection window, choose the Linux
guest systems on which to apply the reconfiguration, and click Yes.
- 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.
