Directly attached I/O in a guest partition running Linux
With directly attached I/O, Linux manages the hardware resources directly, and all
I/O resources are under the control of the Linux operating system. You can allocate
disk units, tape devices, optical devices, and LAN adapters to a guest partition
running Linux.
You must have an NWSD to install Linux in a guest partition. After you install Linux,
you can configure the partition to start independently.
For directly attached hardware, all failure and diagnostic messages are displayed
within the guest partition.
Connectivity to the storage unit from i5 Linux is solely through fibre-channel
adapters. For more information about the adapters and the Linux device, see
http://www-1.ibm.com/servers/eserver/iseries/linux/fibre_channel.html.
For more detailed information about how your company might use a guest partition
with I/O resources go to http://publib.boulder.ibm.com/iseries/v5r2/ic2924/index.htm
or contact your IBM marketing representative or IBM Business Partner for further
assistance on using directly attached I/Os in a guest partition.
Ordering a new server or upgrading an existing server to run a guest
partition
This section tells you who to contact to order a new server or upgrade an existing
server to run a guest partition.
The LPAR Validation tool emulates an LPAR configuration and validates that the
planned partitions are valid. In addition, the LPAR Validation Tool allows you to test
the placement of i5/OS and Linux hardware within the system to ensure that the
placement is valid. Refer to Logical Partitions for information on the LPAR Validation
Tool (LVT).
Contact your IBM marketing representative or IBM Business Partner to enter the
order. You can enter the order by using the iSeries configurator. The configurator
has been enhanced to support ordering IOAs without IOPs when you define a Linux
partition.
