tionality on the NFS server
VALUES
Failsafe
Default
Allowed values
DESCRIPTION
controls the ability to turn on or off the NFS version 3 readdirplus
functionality on the NFS server. If this functionality is turned off,
the client is forced to use the readdir functionality instead.
Who Is Expected to Change This Tunable?
The distributed file system administrator should examine this value if
performance issues are being experienced when reading large directo‐
ries.
Restrictions on Changing
The tunable is dynamic; tuning will take effect immediately on the run‐
ning system.
What Are the Side Effects of Turning Off the Readdirplus Functionality?
By forcing the client to use readdir instead of readdirplus, the client
is no longer following the NFS version 3 protocol. If problems occur,
turn back on.
WARNINGS

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.
