Notes
1. Some operating systems have size
limitations for logical drives. Before you
save the configuration, you might want to
verify that the size of the logical drive is
appropriate for the operating system. See
the operating system documentation for
more detailed information.
2. To change the configuration, select a
Modify icon button.
5. Select the Apply button to accept and save the
configuration.
6. If you have not already done so, install the operating
system. See the server documentation or the
documentation provided with the operating system for
more information.
After you install the operating system, see “ServeRAID
device drivers and utility programs (installation)” on
page 130 (or see the installation instructions provided with
the server) for information about installing the ServeRAID
device drivers and utility programs.
Learning about custom configuration:
The Custom Configuration path allows you to manually
configure the ServeRAID subsystem. Using this path, you
can select the drives that you want to include in each
array, define the number and size of the logical drives for
each array, and select the drives that you want to use as
hot spares.
Before you select the Custom Configuration path, consider
the following:
If you are not familiar with the IBM implementation of
RAID technology, you might want to review the
information provided in “Understanding RAID
technology” on page 67 before you begin.
Each ServeRAID controller supports a maximum of
eight arrays.
Each ServeRAID controller supports a maximum of
eight logical drives.
When you create an array, you group hard disk drives
into one storage area. You can define this storage
area as a single
logical drive, or you can subdivide it
into several logical drives. Each logical drive appears
to the operating system as a single physical hard disk
drive.
If you have only one array, you can define it as a
single logical drive, or you can divide it into several
logical drives. Typically, the first logical drive defined
on the first ServeRAID adapter or controller found by
