Answer

  • When a node panics, a core dump occurs.
  • The system creates a core dump file that technical support can use to troubleshoot the problem. 
  • The architectural method by which the core dump file is saved depends on the NetApp AFF or FAS storage system model:
    • SaveCore (also known as "savecore" or "save core")
    • NoSaveCore (also known as "nosavecore" or "no save core").
  • The following table outlines the differences between these two core dump saving architectures:
SaveCore Platform Attributes NoSaveCore Platform Attributes
Node root aggregate and node root volume are a larger size in order to store core dump files. Node root aggregate and node root volume are smaller, since core dump files are not saved to the node's root volume.
Cores are dumped to a spare disk (or sprayed across multiple spare disks) at the time of the panic. Cores are dumped to a partition on the boot device (or a dedicated core dump device).
After a node reboots, the core file is saved to the root volume. The core dump in the boot device is considered "saved" when it is dumped.

 

  • The following table shows each platform model's core saving architecture:
