I have a disk showing (prefail) in the vol status -r
If I look at the sasadmin dev_stats out put the disk in question shows 45.3K in the cmd error column
A lot of the other disks show 39K in the same column...am I looking at lots of disks heading for prefail?
Thanks for any advice/info
Some handy kbs: (Indeed, that's high number of errors)
Why does a drive show as prefailed in Data ONTAP?https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/Why_does_a_drive_show_as_prefailed_in_Data_ONTAP

Is firmware up-2-date ?https://mysupport.netapp.com/site/info/firmware/disk-drive
No worries. I would suggest getting the firmware updated asap (By default, drive firmware is updated nondisruptively on eligible drives automatically in the background.)
Also, get the DQP up to date:https://mysupport.netapp.com/site/downloads/firmware/disk-drive-firmware/download/DISKQUAL/ALL/qual_devices.zip
