About GRF logs and dumps
Accessing a log file
To display the contents of a specific log file, change directory to
command to display the contents of a specific log file. To access output of grconsole log, use
this sequence of commands:

Dumps

The GRF compresses dumps to save space, compressed files are appended with
Dumps provide specific information useful for monitoring and debugging GRF operations. If
you are working with Customer Support, they may ask for a system or media card dump. The
procedure to install a PCMCIA device for logging also specifies that dumps be sent to the
device.

System dump

If the GRF is reset or it panics, a dump is saved in the
convention
dump is usually too large to send by e-mail. Customer Support will tell you how to send it to
them.
The grsavecore command copies and formats information generated from a kernel panic as the
data is written to standard output. The formatted data is written to
/var/crash

Media card dumps

The grdump program saves and manages media card dumps. By default, two dumps are saved
per day for each media card. Dumps are collected from media cards when they panic or when
they are reset by the system administrator using grreset -D (this command instructs the media
card to dump when it comes back up).
Media card dumps are stored in
grdump.n.x.gz
3....
A media card dump is generally 4–8MB, and can sometimes be e-mailed. Customer Support
will tell you how to send it to them.

Panic dumps sent to external storage

The mountf and grdump commands enable the grdump program to work with an external
storage device to capture media card dumps.
When a media card panics and there is a formatted external flash device plugged into either
PCMCIA slot, a copy of the dump is automatically saved under the
the external flash.
