Retrieving a Crash Dump File
66
Note: During the time when the crash dump file is being moved to
the /snfs/Kdumps directory, the system will be unavailable or
in Limited Mode. This can take up to 30 minutes to complete.
Regardless of the method used to access the DXi6900 G1 system, the
crash dump file is stored in the following directory: /snfs/Kdumps/
1 Once you are logged into the DXi6900 G1 system, grep for
messages in the messages file to see if the crash dump file is
available.
# grep KDUMP /var/log/messages
