Accessing the Crash Dump File
There are several ways of accessing a crash dump file:
l
Use WebEx to remotely access the customer system.
l
If the customer is using Guardian, access the customer system remotely using Guardian.
l
Use WinSCP to remotely access the customer system
l
Attach to the DXi6900 G2 system directly using
ServiceLogin
access.
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 G2 system, the crash dump file is stored in the
following directory:
/snfs/Kdumps/
1. Once you are logged into the DXi6900 G2 system,
grep
for
KDUMP
messages in the messages file to see
if the crash dump file is available.
# grep KDUMP /var/log/messages
