Understanding the Local File System
The Management Input/Output (MIO/UMIO/MIO2) card provides control and management for the system.
The local file system is made up of files that are stored on one or more of the following:
•
/flash - Flash memory located on the circuit board of the MIO/UMIO/MIO2, is the default storage media
for the operating system software image, CLI configuration, and crash log files used by the system.
•
/usb1 - This device is available when a USB memory stick is inserted on the front panel of the active
MIO/UMIO/MIO2.
•
/hd-raid - This is the solid state hard disk array supported by the Fabric and Storage Cards (FSCs) and
accessed via the active MIO/UMIO/MIO2.
File Types Used by the Local File System
The following file types can be located in the local file system:
•
Operating System Software Image File: This binary file type is identified by its .bin extension. The
file is the operating system that is loaded by the system upon startup or reloading. This is an executable,
read-only file that cannot be modified by end users.
