To prevent potential downtime and data loss,
add a second disk
to the rootvg storage pool and mirror the two disks.
When you install the Virtual I/O Server, Virtual I/O Server automatically
creates
a storage pool called rootvg and assigns one physical volume to rootvg.
The Virtual I/O Server software
(including
the Integrated Virtualization Manager) and
any data
that the Virtual I/O Server software
uses initially is stored on the management partition (partition ID
1) on that
physical volume. If that disk would fail, you would be unable to manage
your
client partitions and would suffer downtime and the loss of data.
To prevent
this kind of interruption to your business, you need to add a second
disk
to the rootvg storage pool and mirror the two disks.
Before
you start,
ensure you meet the following requirements:
- The Integrated Virtualization Manager is at version
1.5 or later. To update the Integrated Virtualization Manager,
see Viewing and updating the code level of the Integrated Virtualization Manager management partition.
- You are the
prime administrator (padmin).
To mirror
the management partition, complete the following steps:
- Add a new physical volume to the rootvg storage
pool. For
instructions, see Modifying storage pools using the Integrated Virtualization Manager.
- To mirror the new volume to ensure that the it has
all of the software
and data that the original volume has, complete the following steps:
- Open a virtual terminal window to the
management partition. For instructions, see Opening a virtual terminal session for a logical partition.
- Sign
on to Virtual I/O Server using
the padmin user ID and password.
- At the
command prompt, run the mirriorios command
as follows:
mirrorios Physicalvolume
where Physicalvolume is
the name of the volume that you just added to rootvg.Restriction: The mirrorios command
mirrors only the rootvg storage pool. It does not mirror other volume
groups
or any virtual disks that are created on rootvg after it is initially
mirrored.
