4. Retrieve the KDUMP trace from the message so it can be used with the problem description:
# grep KDUMP kdump_CX0916BVA00005_Flames_2009-07-02_11h43m48s/varlogmessages-
2.6.19-2smp_CX0916BVA00005_2009-07-02_11h43m48s
5. Compress the crash dump folder using the following command:
# tar jcvf kdump_CX0916BVA00005_Flames_2009-07-02_11h43m48s.tar.bz2 kdump_
CX0916BVA00005_Flames_2009-07-02_11h43m48s
After compressing the file using
tar
command, the following crash dump file is available:
kdump_CX0916BVA00005_Flames_2009-07-02_11h43m48s.tar.bz2
Note:
The file size is approximately 2 GB to 30 GB compressed (32 GB to 128 GB uncompressed),
including log files for the DXi6900-S. This process can take 30–45 minutes to complete.
6. To create a checksum file that can be used to verify the correct transmission of the KDUMP file, use the
following command:
md5sum kdump_CX0916BVA00005_Flames_2009-07-02_11h43m48s.tar.bz2 > \
md5sum_ kdump_CX0916BVA00005_Flames_2009-07-02_11h43m48s.tar.bz2
Executing this command will produce a checksum file and place it in the
md5sum_ kdump_
CX0916BVA00005_Flames_2009-07-02_11h43m48s.tar.bz2
file. The
>
option produces and “output
to” and the
\
option is a UNIX continuation marker that tells the command to continue on the next line.
Transferring the Crash Dump File
Use WinSCP to transfer the crash dump file from the DXi system to the attached service laptop.
Note:
Ensure that the laptop is connected using Ethernet to the DXi (either directly or over the
customer’s network) and you have set your IP address accordingly so that you can communicate with
the DXi system. Verify connectivity by accessing the DXi web interface.
1. Launch WinSCP.
WinSCP displays the initial login screen which includes all of the default options and can be used to
successfully connect (see
).
