The minimum firmware revision for each filer is shown in the following table.

For instructions about upgrading your filer firmware, see the Software and Firmware Upgrade Guide.

Compression for core dump files on F500, F600, and F700 filers

Data ONTAP 5.3 supports compression for core dump files on filers in the F500, F600, and F700 series. This means that less disk space is required to perform core dump operations than in previous releases. Also, the time to perform these operations is the same as or less than the time required in previous releases.

Disks required to store a core dump

When a core dump occurs in a filer, the memory and NVRAM are dumped to a set of areas at the beginning of all the disks that has a fixed size. Therefore, a filer with a large amount of memory but not enough disks does not have enough room to perform a full core dump. If there are not enough disks on a filer, a partial core dump is performed.

The minimum number of disks that must be installed for a filer to successfully perform a core dump is shown in the following table.
