Replacing a boot device in an N6200 series system running Data
ONTAP 8.x
The boot device stores a primary and secondary set of system files on it (also
called the
boot image ) that the system uses when it boots. To replace the boot
device, you must complete a specific sequence of tasks.
Before you begin
Before extracting the compressed system files during the boot device installation
process, make sure that the utility you use is set to suppress any automatic CR/LF
conversions in the extracted files.
If you experience any problems during netboot, you can verify the integrity of the
files extracted from the package by comparing the
md5sum
values stored in the
MD5SUMS
file.
