Verifying the TFTP
Process
To verify that a TFTP transfer can occur from the PathBuilder switch to the
TFTP server, follow these steps:
1 Obtain a listing of the files on the PathBuilder switch to select one to
transfer using:
df <directory>
2 If you are using a UNIX TFTP server, create a zero byte file with the name
of the file you selected, and with the proper permissions, using:
touch <filename>
chmod 666 <filename>
3 Transfer the selected file from the PathBuilder switch to the TFTP server
using:
COpy [<device>:]<src_filename> [<device>:][<dest_filename>]
For example, to copy a source file named system to destination /dump/
using the TFTP server at IP address 139.88.132.192, enter:
COpy a:/primary/system 139.88.132.192:/dump/system
4 Verify that the file was transferred to the correct location on the TFTP
server.
Verifying the
Memory Dump
Procedure
To verify that the memory dump process works, simulate a failure of the
PathBuilder switch. At the Enterprise OS # prompt, enter:
su dm BBBBBBBB
The system responds with the following information:
PANIC Trap 3 (ILLEGAL DATA ADDR)
