Diagnosis Guide

Before you begin

Before starting to debug the IBM Virtual Shared Disk and IBM Recoverable Virtual Shared Disk subsystems, consider the following tasks that will make the job easier:

1. Set up a working collective of the virtual shared disk nodes. All of the diagnostic procedures that use the dsh command in the remainder of this chapter assume that you have done this. For instructions on how to set up the working collective, see the dsh command description in PSSP: Command and Technical Reference.
2. If you add the directory /usr/lpp/csd/bin to your path you will not have to use the fully qualified path name when issuing IBM Virtual Shared Disk commands. To do this, issue this command:

   export PATH=$PATH:/usr/lpp/csd/bin
   

   Note:

   The path must be fully qualified when using the dsh command, or the DSHPATH environment variable can be set.
