If you specify a nondefault filename, and later attempt to change the file type from linear to daily,
the request will be rejected if the filename specification does not include a date substitution string.
When writes will occur
When you enable NFS on a port, you may configure a buffer size and a time interval, which will be
used to determine when accumulated data is written to the NFS server file.
• If you configure a buffer size of zero bytes and a time interval of zero seconds, data will be
written to the file as soon as the data is available (not to exceed one write per second).
• If you configure a buffer size of zero bytes and a non-zero time interval, accumulated data will
be written to the file each time the specified interval elapses (unless 3584 or more bytes accu-
mulate in the buffer before an interval elapses, in which case the data will be written then).
• If you configure a non-zero buffer size and a time interval of zero seconds, data will be written
when the specified number of bytes has accumulated, regardless of elapsed time. (If you con-
figure a size value larger than 3584, the data will be written whenever 3584 or more unwritten
bytes accumulate.)
To display NFS configuration information and mount status:
Issue a Show NFS command. The display will include the status of the mount operation. For more
information, see Show NFS command on page 76.
SHOW NFS
To enable/disable and configure NFS on a port:
1. To enable NFS on one or all ports, issue a Port NFS command with the Enable parameter.
PORT <port>|ALL NFS ENABLE [FILE=<file>] [SIZE=<bytes>] [TIME=<sec>]
You may specify a filename or use default values; see NFS filenames on page 36.You may also
configure size and time thresholds; see When writes will occur on page 38.
2. To disable NFS on one or all ports, issue a Port NFS command with the Disable parameter.
PORT NFS DISABLE
For more information, see Port NFS command on page 60.
To display NFS port history file information:
Issue a Show Port command. The display includes the current port NFS status, which covers the
most recent 15 minutes or since NFS history was most recently enabled for that port.
SHOW PORT
-or-
Issue a Show NFS command. In addition to displaying the current NFS mount status, this command
will also show any port error status other than No Recent Errors Detected.
SHOW NFS
NFS Error Codes and Port Status on page 105 describes the error codes that may be displayed.
