nfs3_jukebox_delay(5)					 nfs3_jukebox_delay(5)

NAME
       nfs3_jukebox_delay  -  control  the  length  of	time the NFS version 3
       client  waits  before  re-transmitting  a  request  after  receiving  a
       NFS3ERR_JUKEBOX error

VALUES
   Failsafe
   Default
   Allowed values
   Recommended values
       A  warning  will	 be issued at runtime if the tunable is set to a value
       less then 100 hundredths of a second or greater than  60000  hundredths
       of  a  second  since  this is outside the tested limits.	 This is not a
       serious warning but just an information message for the administrator.

DESCRIPTION
       controls the duration of time that the NFS version 3  client  waits  to
       transmit	 a  new	 request  after	 receiving  the	 error from a previous
       request. The error, is generally returned from the server when the file
       is temporarily unavailable for some reason. These situations are gener‐
       ally associated with hierarchical storage and CD or tape jukeboxes.

   Who Is Expected to Change This Tunable?
       The distributed file system administrator  should  examine  this	 value
       depending on the speed of the storage on the NFS file server.

   Restrictions on Changing
       The tunable is dynamic; tuning will take effect immediately on the run‐
       ning system.

   When Should the Value of This Tunable Be Raised?
       The value should be increased if there are long delays  in  making  the
       file  available.	 This  will  reduce  network  overhead due to repeated
       retransmissions.

   What Are the Side Effects of Raising the Value?
       Increasing the delay before retransmission will impact  performance  if
       the file unavailability is shorter than the increased delay.

   When Should the Value of This Tunable Be Lowered?
       If  the	time  the  file	 is unavailable is small, then decreasing this
       value should not impact performance.

   What Are the Side Effects of Lowering the Value?
       If the time the file is unavailable is large, then  there  will	be  an
       increase in network overhead.

WARNINGS
       All HP-UX kernel tunable parameters are release specific.  This parame‐
       ter may be removed or have its meaning changed in  future  releases  of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may
       cause changes to tunable parameter values.   After  installation,  some
       tunable	parameters may no longer be at the default or recommended val‐
       ues.  For information about the effects of installation on tunable val‐
       ues, consult the documentation for the kernel software being installed.
       For  information	 about	optional  kernel  software  that  was  factory
       installed on your system, see at
