IBM PowerVM Configuration Use Cases

The following use cases describe the handling of LPAR AIM instance entries for managed systems (POWER Servers) and Virtual I/O Servers in the Administration tab:

• You add a managed system instance with one or two Virtual I/O Servers to the LPAR AIM Servers panel (instance table).

  The LPAR AIM detects what Virtual I/O Servers are available on the managed system. The AIM creates records for each Virtual I/O Server and the managed system in its instance table. The states of Virtual I/O Servers are set to "invalid configuration", that is, credentials are not yet specified. The managed system instance is in "pending VIOS" state and waiting for valid VIOS credentials.

• You define correct Virtual I/O Server credentials in the Virtual I/O Servers panel.

  The user interface displays a message about the success of the operation. When you apply the Virtual I/O Server credentials to the appropriate LPAR AIM instance (), the Virtual I/O Server and the managed system change to "ready" state.

• You enter incorrect Virtual I/O Server credentials in the Virtual I/O Servers panel.

  The user interface displays a message about the failure of the operation. When you try to apply incorrect Virtual I/O Server credentials to the LPAR AIM instance (), the Virtual I/O Server changes to "authentication failed" state. The managed system instance changes from "pending VIOS" state to "out of date" due to connection problems.

• You define correct Virtual I/O Server credentials in the Virtual I/O Servers panel, but there is no read/write access community string available.

  When you try to apply Virtual I/O Server credentials to the appropriate LPAR AIM instance (), the user interface displays an error message. The message indicates that no write access community string is available.

• You add a managed system instance without Virtual I/O Servers.

  The managed system instance appears in the instances table in "ready" state.

• You add a Virtual I/O Server to a managed system.

  The new Virtual I/O Server instance appears in the instance table with "invalid configuration" state. The managed system instance changes to "pending VIOS" state and is waiting for valid VIOS credentials.

• You remove a Virtual I/O Server in "invalid configuration" state from a managed system.

  The LPAR AIM removes the corresponding record from the instance table and the managed system changes to 'ready' state.

• You remove a Virtual I/O Server in "ready" state from a managed system.

  The LPAR AIM removes the corresponding record from the instance table.

• You remove a managed system instance with one or two Virtual I/O Servers.

  The managed system instance and associated Virtual I/O Server entries disappear from the instances table.

• The IBM PowerVM administration pane displays status information through icons and tooltips.

  Tooltips become visible when you hover the cursor over warning and error icons.

  The following icons can appear:

  Discovery in progress - Wait until the platform manager synchronizes all data.

  Multiple instances - This instance is managed by multiple AIMs. Remove the duplicate instance.

  Error - See tooltips for more information.

  Warning - See tooltips for more information.

  Disabled - This instance is not managed.

  Unknown - The status of this instance is unknown.
