What's new in Virtual I/O Server

May 2009

The following updates have been made to the content:

• You can use the HMC graphical interface, version 7 release 3.4.2 or later to complete many virtual storage and networking tasks for a Virtual I/O Server. In previous versions, you were required to complete these tasks using a Virtual I/O Server command-line interface. The following tasks are updated to include links to the HMC graphical interface instructions, when appropriate.
  • Creating a virtual target device on a Virtual I/O Server
  • Creating logical volume storage pools on a Virtual I/O Server
  • Creating file storage pools on a Virtual I/O Server
  • Creating the virtual media repository on a Virtual I/O Server
  • Creating volume groups and logical volumes on a Virtual I/O Server
  • Configuring a shared Ethernet adapter
  • Assigning the virtual fibre channel adapter to a physical fibre channel adapter
  • Increasing virtual SCSI device capacity
• Logical partitions can share the memory in the shared memory pool by using the PowerVM™ Active Memory™ Sharing technology (or shared memory). A Virtual I/O Server (VIOS) logical partition that is assigned to the shared memory pool (hereafter referred to as a paging VIOS partition) provides access to the paging space devices for the logical partitions that are assigned to the shared memory pool. The following information is new for shared memory:
  • Shared memory
  • Paging VIOS partition
  • Paging VIOS partition requirements

  For more information about what's new for shared memory, see What's new in Logical partitioning.
