Changing a storage pool for a VIOS logical partition using the HMC

You can use the Hardware Management Console (HMC) to extend a storage pool, to reduce or remove a storage pool, and to assign a storage pool as the default storage pool for the managed system.

1. In the navigation area, expand Systems Management > Servers, and select the server on which the Virtual I/O Server logical partition is located.
2. In the Tasks pane, click Configuration > Virtual Resources > Virtual Storage Management.

   The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.

   When the HMC is at version 8.7.0, or later, complete the following steps to view and change storage pools:

   1. In the navigation pane, click the Resources icon .
   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.
3. Select a Virtual I/O Server logical partition.
4. Click the Storage Pools tab to display a list of storage pools defined for the managed system.
5. Select the storage pool from the table that you want to change.
6. From the Select Action menu bar of the Storage Pools table, select the storage management task that you want to perform:
   • Properties to view the properties of the selected storage pool.
   • Extend to add storage capacity to the selected storage pool. To extend logical volume-based storage pools, add physical volumes to the storage pool. To extend file-based storage pools, add space from the parent storage pool to the file-based storage pool.
     Note: You cannot add a physical volume to a storage pool if it is already assigned to a partition.
   • Reduce to reduce the size of the selected storage pool. To reduce logical volume-based storage pools, remove physical volumes from the storage pool. To reduce the file-based storage pool, the storage pool is deleted.
     Attention: Reducing a storage pool that contains virtual disks could potentially destroy data stored on the virtual disks.
