Linux Device Lister


This tool will list the devices mounted on an OES Linux server that has NSS installed on it. It uses the Virtual File Services (Originally called Virtual File Services for NetWare) which were ported over to Linux. The SDK for this API set can be downloaded from The objective of the tool is to list the devices in an XML output as specified in the VFS for NetWare specification. It is intended to be used as a sample script for developers that may want to use the VFS API set to view and manage storage.

How to Use the file: is a Perl script. So Perl must be installed and running on the Linux server that this file is being loaded on. NSS must be installed to get the VFS support.

From a terminal prompt type: Perl <enter>

A sample output would be the following:

grep57:/a # perl
file is now open
<virtualIO><datastream name="command"/></virtualIO><nssRequest><device><listDevices/></device></nssRequest>
<deviceName>sda</deviceName><deviceID>sda</deviceID><deviceType>0</deviceType><unitSize>512</unitSize><sectors>63</sectors><capacity>143374650</capacity><alignment>16065</alignment><result value="0"><description>success</description></result>
<deviceName>sdb</deviceName><deviceID>sdb</deviceID><deviceType>0</deviceType><unitSize>512</unitSize><sectors>63</sectors><capacity>286749480</capacity><alignment>16065</alignment><result value="0"><description>success</description></result>
<result value="0"><description>success</description></result>
<result value="0"><description>zOK</description></result>

The specifications explain the XML tags, but the information present here would let someone know that two devices were found sda and sdb. Information about the two devices is also displayed.
