The Snapdump feature provides the Dell Technical Support team with the debug information that can help to find the cause of firmware failure. In the instance of firmware failures, the firmware collects the logs and information at the time of failure, which are stored in a compressed file called a snapdump.

Snapdumps are also generated manually to provide additional debug information. When a snapdump is generated, it is stored in the controller's cache memory. In the event of a power loss the controller will offload the snapdump as part of its cache preservation mechanism. Snapdumps are preserved by default through four restarts before it is deleted.

To generate, delete, or download a stored snapdump, see the Dell PowerEdge RAID Controller CLI Reference Guide available on the support site.
