Abstract 

   Parallel NFS (pNFS) extends Network File System version 4 (NFSv4) to 
   enable direct client access to file data on storage, bypassing the 
   NFSv4 server.  This can increase both performance and parallelism, 
   but requires additional client functionality, some of which depends 
   upon the type of storage used.  The pNFS specification for block 
   storage (RFC 5663) describes how clients can identify the volumes 
   used for pNFS, but this mechanism requires communication with the 
   NFSv4 server.  This document adds a mechanism to RFC 5663 that 
   enables identification of block storage devices used by pNFS file 
   systems without communicating with the server.  This enables clients 
   to control access to pNFS block devices when the client initially 
   boots, as opposed to waiting until the client can communicate with 
   the NFSv4 server.
