touch dm06BA6A.pdm
2 Ensure that all users have permission to write to the target directory and
filename. To determine this on a UNIX system, enter:
ls -a
3 To change write access permissions on a file or directory, enter:
chmod 666 dm06BA6A.pdm
If a system crash occurs, the system performs a partial dump and outputs
an ASCII text file to the file named dm06BA6A.pdm. If QuadWan
modules are included in the PathBuilder switch model, this file includes
debug information for the QuadWan modules.
See the UNIX system documentation if you have any problems.
QuadWan Dump Files
To create the dump files for QuadWan modules, follow these steps:
1 On a UNIX TFTP server, create two files with the names dmXXXXXX.qw1
and dmXXXXXX.qw2, where XXXXXX is the last six characters of the
MAC address of the motherboard of the PathBuilder switch.
For example, if the last six characters of the MAC address of the
PathBuilder switch are 06BA6A, enter:
touch dm06BA6A.qw1
touch dm06BA6A.qw2
2 Ensure that all users have permission to write to the target directory and
filename. To determine this on a UNIX system, enter:
ls -a
3 To change write access permissions on a file or directory, enter:
chmod 666 dm06BA6A.qw1
chmod 666 dm06BA6A.qw2
If a system crash occurs, the system performs a dump and outputs
QuadWan information to these files.
See the UNIX system documentation if you have any problems.
