[local]host_name# directory { /flash | /usb1 | /hd-raid } 

  The USB device must be pre-configured via the hypervisor for the usb1 keyword to work. 

The contents of CLI configuration and boot.sys files, contained on the local file system, can be viewed off-line (without 
loading them into the OS) by entering the following command at the Exec mode prompt: 

[local]host_name# show file url { /flash | /usb1 | /hd-raid } /filename 

Where: 

 is the path name for the location of the file and 

 is the name of the file, including any extension. 

  The USB device must be pre-configured via the hypervisor for the usb1 keyword to work. 

 

  Operator and inspector-level users can execute the show file command but cannot execute the 

directory command. 

The StarOS image file, identified by its .bin extension, is a non-readable, non-editable file that executes on the system, 
creating its runtime operating system (OS). 

It is important to verify a new StarOS image file before attempting to load it. To accomplish this, a proprietary 
checksum algorithm is used to create checksum values for each portion of the application stored within the .bin file 
during program compilation. 

This information can be used to validate the actual file against the checksum values stored within the file during its 
compilation. If any portion of the image file has become corrupted (for example, the file was truncated or was 
transferred using ASCII mode instead of binary mode), then this information is reported and the file is deemed 
unusable. 

To validate a StarOS image file, enter the following command at the Exec mode prompt: 

[local]host_name# show version { /flash | /usb1 | /hd-raid } 
/[directory]/filename [all] 

The output of this command displays the following information: 



 

Version number 



 

Image Description 



 

Image Date 



 

Boot Image 

If an invalid file is found, the system displays a failure message similar to these: 

Failure: Image /flash/image_version.bin CRC check failed!
