When a hardware or software failure causes the storage system to panic, the system creates a core file that technical support can use to troubleshoot the problem. The storage system stores the core file in the /etc/crash directory on the root volume.
command, which is included in the default /etc/rc
file on the root volume, performs the following tasks:
- Produces a core.n.nz file. The n in the file name is a number. The string nz indicates that the file is compressed.
- Displays a message on the system console.
- Logs a message in /etc/messages on the root volume.
