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 PDMM 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 parameters 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.
