Description
DRV.NVCHECK returns a checksum of all the drives NV parameters. This parameter can be used to
detect changes in parameters.
In some applications a master device needs to confirm the AKD drive contains an expected set of drive
parameters. Reading and checking all the drive parameters individually is viable but this would be a long
process involving many reads over the network. DRV.NVCHECK is a checksum on all the NV param-
eters and this parameter can be read in a single transaction. DRV.NVCHECK will return the same number
if all the drive parameters match. If any of the drive parameters are changed then DRV.NVCHECK will
return a different value.
