When a hardware or software failure causes the filer to crash, the filer creates a core file that Network Appliance Technical Support can use to troubleshoot the problem.
On the first boot after a system crash, the filer stores the core file in the /etc/crash directory on the root volume.
The savecore command, which is included in the default /etc/rc file on the root volume
A core dump file contains the contents of memory and NVRAM. Core dumps are written 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.
The following table 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.
| Memory (in MB) | Disks Needed |
|---|---|
| 32 | 2 |
| 64 | 4 |
| 96 | 5 |
| 128 | 7 |
| 160 | 9 |
| 192 | 10 |
| 224 | 12 |
| 256 or more | 14 |
Your filer sends email automatically to Network Appliance Technical Support upon each system reboot.
If you disabled automatic email, you should contact Network Appliance Technical Support when your system creates a core file.
