Memory Dump Procedures

monitor,” as described in Chapter 4, “Configuration.” If this parameter is set
to “Reboot only,” the communications server reboots automatically after a
failure, overwriting RAM. If it is set to “Upload then reboot” the commu-
nications server does not allow a memory dump to be written to a diskette.
To write a memory dump to the CS/3100 diskette, you need six or more
high-density (2 MB) 3.5-inch diskettes (1.44 MB formatted). You do not need
to format the diskettes. The
du
command automatically performs this step.
The memory dump procedure reinitializes the monitor and saves the
contents of memory. To write the memory contents to diskette, follow these
steps:
1
Enter monitor mode, as explained in “Entering the Firmware Monitor”.
In some instances, a crash may leave the disk drive unusable because some
monitor parameters were overwritten. In this case, the server may respond
with an error message. To recover, enter the soft reset command:
k
2
From the console, enter the dump command:
du
The server prompts you with the following:
Enter the density of the dump diskettes
Escape to abort the dump
Return to use the default density (2mb):
3
Press the Return key to select the default, 2 MB (high-density).
The server then calculates the number of diskettes required for the memory
dump, and displays the following message:
***
N diskette(s) will be needed for the dump operation***
Diskettes will be formatted prior to writing
Insert a diskette
Hit any key to continue
Escape to abort the operation
