what is the bestway to convert 32-bit aggregate to 64-bit.
created a new aggregate using oncomand system manager and asigned all the disk, I have noticed that 32-bit. I think the oncomand default was set to 32-bit.
how can i make it 64-bit
Since it is a 32-bit aggregate now, the only way to convert it to a 64-bit aggregate is to add disks in a quantity that would overcome the 32-bit aggregate size limit for your controller model.
Easiest way would be destroying the current 32-bit aggregate and recreating it. But this may not be possible now since you could have been using it already.
