consists of the following steps:
•

Accessing the Crash Dump File

• Using WinSCP to Compress and Transfer the Crash Dump File
• Transferring the Crash Dump File
There are several ways of accessing a crash dump file:
• Use WebEx to remotely access the customer system.
• If the customer is using Guardian, access the customer system
remotely using Guardian.
• Use WinSCP to remotely access the customer system
• Attach to the DXi6900 G1 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.
