wsize=n
(default=32768)
The number of bytes the NFS client sends to the
NFS server in a single write request.
If packets are being dropped between the client
and the server, decrease wsize to 4096 or 2048. To
find out whether packets are being dropped, issue
the NFSstat -rc command at the HP-UX prompt.
If the timeout and retrans values returned by
this command are high, but the badxid number is
close to zero, then packets are being dropped
somewhere in the network.
vers=n
(default=3)
The version of the NFS protocol is used. The
default is NFS version 3. When the user doesn’t
provide a version number, the NFS mount
command tries to use the highest available
version of NFS. If the NFS server does not
support version 3, the file system will be mounted
using version 2.
If vers=n option is used, the NFS mount
command attempts the mount with the requested
version. If this version is not supported by the
NFS server, then the mount command will fail.
For example, if vers=3 is specified and NFS
version 3 is not available, then the mount
command will fail.
