Connecting Storage Enclosures
The following diagrams illustrate how to cable XR-series hardware RAID storage enclosures. Cable your
storage exactly as illustrated to ensure proper functionality.
Note that the XR 6500 series and XR 6412 series storage assemblies do not support configurations with two
XR RAID enclosures.
WARNING Do not power on your storage before installing Linux, otherwise the Red Hat installer might attempt
to format the storage array and use it as the system disk.
