Hi,

Referring to https://library.netapp.com/ecmdocs/ECMP1511537/html/man1/na_aggr.1.html; "check" is definitely an option for 8.2.4 7-mode.

Your experience is odd, because from the KB article at https://kb.netapp.com/support/s/article/ka31A00000013WlQAI/how-to-perform-64-bit-aggregate-conversion-using-cli-in-data-ontap-7-mode-and-clustered-data-ontap?language=en_US, it shows the "check" command being valid without specifying additional disks. You only need to specify disks when used with the "normal" tag.

Something that might help you is from DoT 8.2.1 Netapp added in-place expansion procedure for 32-bit aggregates to 64-bit improved without requiring additional disks. Have you tried doing this instead? The command would be:
> aggr 64bit-upgrade start Aggr1

Have a look at the TR document for more info on this: http://www.netapp.com/us/media/tr-3978.pdf.

Hi Folks,
NetApp Release 8.2.4P6 7-Mode

Running 
#aggr add Aggr1 -64bit-upgrade check

aggr add: Neither a count of disks nor a list of disks to add
to the aggregate was specified.


Running with # of disk seem to be also not running check

#aggr add Aggr1 -64bit-upgrade check 6 
Note: preparing to add 4 data disks and 2 parity disks.
Continue? ([y]es, [n]o, or [p]review RAID layout) p

Is "check" no longer an option in 8.2.4?
