Chapter 9. Configuring zones
Zoning for your integrated storage is configured automatically for the IBM
BladeCenter S SAS RAID Controller Module.
The IBM BladeCenter S chassis has a default zoning configured allowing all blades
to communicate with all disks. In some cases, isolating one or more disks can be
useful in problem determination procedures so it is possible to adjust the zoning. It
is recommended however, that you maintain the default zoning settings for regular
operations.
Note: Zoning for the RAID Controller is set up automatically. Because the RAID
Subsystem acts as one unit, altering the zoning disables communication between
the storage modules and blade servers.
Understanding the predefined zone
There is only one predefined zone for use with the RAID Controller.
Due to the nature of RAID technology, the default predefined zone used with the
IBM BladeCenter S chassis is set so that all the Blade Servers can communicate
with all of the disk storage. In the course of troubleshooting, you might want to
isolate a Blade Server as a diagnostic tool, but it is recommended that you
maintain the default zoning settings for regular operations.
