Hello,
The AGGR isnt realy the issue ... but on a NetApp HA Pair, you have 2 NODEs and this nodes, need to have vol0 to boot, this vol0 need to be on a AGGR. So each node must have an AGGR to be able to boot
But, in some cases, like ADP for internal shelvers, it's possible to split disk in 3 parts, and make AGGR with this parts
The first part is realy thin, and usable for AGGR and VOL0
Questions :
- Are you in ADP mode on your system ?
- Waht is your system model ?
