file that Dell technical support can use to troubleshoot the problem.

directory on the root volume.

A core dump file contains the contents of memory and NVRAM. Core dumps are writ-
ten to a set of areas at the beginning of all the disks. The core dump area on each disk
has a fixed size of approximately 20,447,232 bytes. Therefore, a filer or appliance with
a large amount of memory can have an insufficient amount of core dump disk space
to store a full core dump.
Table 2-13 shows how many disks are needed to store a full core dump for the
amount of memory you might have in a specific filer or appliance.
