Exadata Database Machine V2 - Version All Versions to All Versions [Release All Releases]
Oracle Solaris on x86-64 (64-bit)
Linux x86-64
Oracle Solaris on SPARC (64-bit)
Oracle Exadata & SuperCluster Engineered Systems

Goal

Oracle (Exadata & SuperCluster) Engineered Systems ship with a utility called DCLI (Distributed Command Line Interface),
along with group files for use with same (via the -g switch) that list the multiple Compute Nodes & Storage Cells.  

However, although these Engineered Systems _also_ contain multiple InfiniBand (IB) Switches, they do not (by default)
have a suitable DCLI group file for same.  In order to gather common IB diagnostics, it is very useful to create such
a file, and use same to establish Secure SHell (SSH) user equivalency, before running diagnostics.
