Performing a Memory Dump 131
Usually, the target directory is the default TFTP directory. For example, if
the TFTP directory is /home/TFTPdir, and the target directory configured
on the PathBuilder switch is /dump, then the actual target directory is
/home/TFTPdir/dump. Make sure this directory exists on the TFTP server,
as it will not be created by the PathBuilder switch, or the TFTP process
when a TFTP transfer is initiated.
10 Type Q repeatedly to exit the System Configuration menus and return to
the Enterprise OS # prompt.
Obtaining the MAC
Address
You need to obtain the media access control (MAC) address of the
PathBuilder switch. This is necessary because the system creates several
dump files on the TFTP server named dmXXXXXX.<EXT>, where XXXXXX
are the last six characters of the MAC address of the motherboard of the
PathBuilder switch. <EXT> can be .s0x, .pdm, .qw1, or .qw2 depending
on the type of file.
To display the MAC addresses, follow these steps:
1 At the Enterprise OS # prompt, enter:
SysInfo
2 Record the MAC address for port 1 when it is displayed. You will use this
number in the next procedure.
Creating Files for the
Memory Dump
Some UNIX TFTP servers do not have the capability to create files if they
do not exist, but can overwrite an existing file. Therefore, you must first
create a set of files with the expected dump file names on the UNIX TFTP
server.
Before beginning this procedure, make sure the TFTP server is running.
On a UNIX system, the ps command with appropriate arguments provides
a listing of the current processes. See the documentation pertaining to
the IP stack on the TFTP server if you have any problems.
Partial Dump File
To create the partial dump file, follow these steps:
1 On a UNIX TFTP server, create files with the name dmXXXXXX.pdm,
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:
