Checking available Data ONTAP versions

You might need to check the current booted kernel and other kernels available on the CompactFlash card if the storage system was started via netboot from an unfamiliar system, if an upgrade was unsuccessful, or if you need to run kernel diagnostics.


By default, a FAS200 series storage system boots the current Data ONTAP release from the primary kernel.

    version -b

    If you enter version, the console displays the version number of Data ONTAP that is currently running.

    If you enter version -b, the console displays the contents of the CompactFlash FAT file system, including name and version information for the primary, secondary (if present), and diagnostic kernels, and the firmware.

    For more information, see the na_version(1) manual page.
