sasadmin dev_stats output

PhilMather — Wed, 04 Jun 2025 09:55:12 GMT

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?

Is firmware up-2-date ?

Hi
Thanks for that.

Looks like the firmware is out of date

Cheers

No worries. I would suggest getting the firmware updated asap (By default, drive firmware is updated nondisruptively on eligible drives automatically in the background.)

Firmware:
https://mysupport.netapp.com/site/downloads/firmware/disk-drive-firmware/download/DISKDRIVE/ALL/all.zip

Also, get the DQP up to date:
