Generating a snapshot file: txsnap

Use txsnap to take a snapshot of the board to diagnose TX-based problems. A snapshot file contains an image of the board memory space. Use a snapshot to view the system as it was at the time the snapshot was taken. By default, the snapshot file is created in the current directory and is named cpsnap.dmp.

To generate a snapshot file for TX boards, run txsnap according to the following syntax:

txsnap -b boardnum -p -r -f filename

where:

Argument

Description

-b boardnum

TX board number for which to generate a snapshot file. Default is 1.

-p

Snaps only PCI-mapped memory.

-r

Creates a raw memory snapshot file without headers.

-f filename

File to which to write the TX board information. Default is cpsnap.dmp.


txsnap is generally run with the -b argument only. Because the resulting snapshot file is greater than 128 Mb, zip the snapshot file before transferring it.
