Changing a virtual disk for a VIOS logical partition by using the HMC

You can use the Hardware Management Console (HMC) to view the properties of the virtual disks on your managed system, as well as to start virtual disk management tasks.

About this task

Virtual disks are also known as logical volumes. To assign the virtual disk to a client partition, ensure that the client partition owns one or more virtual SCSI adapters and that the Virtual I/O Server (VIOS) owns corresponding virtual SCSI adapters that host the client adapter.

To change a virtual disk, be sure you meet the following requirements:
  • The HMC must be at version 7.7.4, or later.
  • The VIOS must be at version 2.2.1.0, or later.
  • Ensure that there is a resource monitoring and control connection between the HMC and the VIOS.

To view and to change virtual disks, complete the following steps in the HMC:

Procedure

  1. In the navigation pane, click the Resources icon The icon represents the Resources function of the HMC.
  2. Click All Systems. The All Systems page is displayed.
  3. In the PowerVM area, click Virtual Storage. The Virtual Storage page opens with the VIOS partitions listed in a table, in the Virtual Storage Management tab.
  4. Select a VIOS and click Action > Manage Virtual Storage.
  5. Click the Virtual Disks tab to display a list of virtual disks on the managed system.
  6. Select the virtual disk from the table that you want to change.
    If a virtual disk is defined as a paging space device and is assigned to a shared memory pool, it is dedicated to providing this function and is no longer available for any other purpose. Consequently, such a virtual disk is not listed here.
  7. From the Select Action menu bar of the Virtual Disks table, select the storage management task you want to perform:
    • Properties to view the properties of the selected virtual disks.
    • Extend to add storage capacity to the selected virtual disks.
    • Delete to delete the selected virtual disk and make the storage resources that belonged to that virtual disk available to other virtual disks.
    • Modify assignment to change the logical partition to which the selected virtual disk is assigned, or to set the selected virtual disk so it is not assigned to any logical partitions.
