Disk upgrade is non-disruptive if all aggregates are RAID_DP. By default it starts as soon as you copy file with new firmware in place. For RAID4 you have to initiate it manually. Can’t comment, I have not met any RAID4 aggregates for years :)

I have downloaded the X410_HVIPC288A15 firmware - is this one truly non-disruptive? The online docs seem overly verbose - what is the short user test version for applying the disk firmware prior to 7.3.5.1P2->8.1RC2 NDU?
thanks
Upgrade
These 96 disks will have firmware updates if the latest disk firmware is loaded on the filer:
96 disks of Model X410_HVIPC288A15.
This firmware is not included in 8.1RC2 and must be downloaded separately. When performing a nondisruptive upgrade, NetApp recommends upgrading disk firmware the day before upgrading Data ONTAP.
