upgrade 32bit aggr to 64bit

how do I upgrade a 32bit aggr to 64 bit? what are the steps and downtime?

Re: upgrade 32bit aggr to 64bit

With ONTAP 8.1, you add disks to grow the aggregate over 16TB and it will automatically convert in the background (no downtime) from 32 to 64 bit.  Growing over 16TB is the only supported method.  If you search this community you will see some posts of a diag mode in place method without adding disks but that is not supported (diag mode command).

You can also replicate from 32 to 64 with ONTAP 8.1 and have a quick downtime while you cutover to the new volume but if you are on 8.1 then the best solution is to add disks and convert the existing aggr for now downtime.

Re: upgrade 32bit aggr to 64bit

It does not do this automatically, you have to explicitly say you want to convert when adding disks. Otherwise it just rejects command if size will exceed 16TiB.

Re: upgrade 32bit aggr to 64bit

System manager should give a popup they can click wen growing to convert. Do you use cli or system manager and is it ontap 8.1?

CLI of course ☺

but im on  8.0.1P3. how do i convert to 64bit without upgrading to 8.1?

Re: upgrade 32bit aggr to 64bit

Basically you can't.

What you can do, is to create new 64-bit aggregate and then migrate the data off the old one, e.g. via Qtree SnapMirror (VSM won't work unfortunately).

Qtree snapmirror or Ndmpcopy if not on 8.1. It might be worth waiting for your upgrade. Then you can upgrade in place by growing the aggr or volume snapmirror too 32 to 64.
