Verifying the subsystem device driver on a pSeries host running Linux

This section provides the steps to verify the SDD installation on the Linux operating system for your pSeries™ host.

1. Check the /opt/IBMsdd directory for the SDD driver and its major components. The SDD installs the device driver and its utilities. The following table lists the SDD driver and its major components.

   Filename	Location	Description
   sdd-mod.o-xxxy	/opt/IBMsdd	The SDD device driver file, where xxx represents the kernel level of your host system and y represents smp or up.
   vpath.conf	/etc	The SDD configuration file.
   executables	/opt/IBMsdd/bin	The SDD configuration and status tools.
   	/usr/bin	The symbolic links to the SDD utilities.
   sdd.rcscript	/etc/init.d/sdd	The symbolic link for the SDD system startup option.
   	/usr/sbin/sdd	The symbolic link for the SDD manual start or restart option.

2. Issue the rpm -qi IBMsdd command to receive information on the particular package. You can also issue the rpm -ql IBMsdd command to list the specific SDD files that you successfully installed on your Linux host system.
3. If the installation was successful, issue the cd /opt/IBMsdd command and then the ls -l command to list all of the installed SDD components. This creates output similar to the following screen:

   -rw-r-----    1 root     root        89370 Sep 26 17:40 sdd-mod.o-2.4.19-smp  

4. The installation process packages the SDD utilities as executable files in the /bin directory. Issue the cd /opt/IBMsdd/bin command and then the ls -l command to view the files in the /opt/IBMsdd/bin directory. This creates output similar to the following screen:

   -rwxr-x---    1 root     root        92683 Sep 26 17:40 addpaths              

   If the installation failed, the system displays a message similar to the following message:

   package IBMsdd is not installed
