So now you have zero’d your disks, but when you check aggr status, you see your aggrs at 32bit! What to do? This means you will need to create a lot of aggrs because there is a 2TB limit (like Vmwares limit in 4.x) on the size!
So here is a demo of how to do this with NetApps Data Ontap software and I give a brief idea of the commands used in the video here:
aggr create aggr1 -B 64 3
This says to create a new “aggr1” that is 64-bit and use any 3 disks to do it.
vol create vol1 aggr1 250g
This says to create a new “vol1”, put it inside the “aggr1” and make the size 250g (which is the minimum size for the root volume of a system)
ndmpd on
Turns on the ndmp daemon
ndmpcopy -l 0 -f /vol/vol0 /vol/vol1
This does a level 0 (default) copy of vol0 to vol 1, -f says to include system files. Think of the old DOS says what happens if you didn’t format with -s. You are correct, it won’t boot.
Now there is 1 more thing we need to do, and that is to set this new volume we created as the root volume:
vol options vol1 root
If you check the status after doing something like this, but not rebooting yet, you will see that 1 volume has a status of “root” and another volume has the status of “diskroot”. This indicates that the volume of “diskroot” will because the “root” volume after the next reboot.
