Hi,
Thank you for your reply.
>You mentioned you tried with '-diskcount' option
I'd like to modify the description, ONTAP chose disks from pool0 and pool1 each.
I don't know why Not enough spares on node1, because there're some spares assigned to node1.
Actually ONTAP selected 6 disks from pool1 in 2.1.*, but asked about
"2.1.0", "2.1.0" in the same loop.
Do you have any ideas and could you share with me?
Anyway does NetApp release a latest TR about ONTAP 9 SyncMirror?
I can't find TR or best practice about the detailed procedure and how to connect
nodes and disk shelves for SyncMirror.

netapp-n11::> storage aggregate create agg4 -mirror -diskcount 12
Info: The layout for aggregate "agg4" on node "netapp-n11-01" would be:
First Plex
RAID Group rg0, 6 disks (block checksum, raid_dp)
Usable Physical
Position Disk Type Size Size
---------- ------------------------- ---------- -------- --------
shared 2.0.12 SSD - -
shared 1.10.12 SSD - -
shared 2.0.0 SSD 1.74TB 1.74TB
shared 1.10.0 SSD 1.74TB 1.74TB
shared 2.0.13 SSD 1.74TB 1.74TB
shared 1.10.13 SSD 1.74TB 1.74TB
Second Plex
RAID Group rg0, 6 disks (block checksum, raid_dp)
Usable Physical
Position Disk Type Size Size
---------- ------------------------- ---------- -------- --------
shared 2.1.0 SSD - -
shared 2.1.1 SSD - -
shared 2.1.2 SSD 1.74TB 1.74TB
shared 2.1.3 SSD 1.74TB 1.74TB
shared 2.1.4 SSD 1.74TB 1.74TB
shared 2.1.5 SSD 1.74TB 1.74TB
Aggregate capacity available for volume use would be 5.94TB.
The following disks would be partitioned: 2.1.0, 2.1.1, 2.1.2, 2.1.3,
2.1.4, 2.1.5.
Warning: Not enough spares on node netapp-n11-01.
Do you want to continue? {y|n}: y
[Job 50] Job is queued: Create agg4.
Error: command failed: [Job 50] Job failed: Failed to create aggregate "agg4"
on "netapp-n11-01". Reason: Current disk pool assignments do not
guarantee fault isolation for aggregates mirrored with SyncMirror. Other
disks in the loop are in a different pool than disks: "2.1.0", "2.1.0".
Use "disk show -v" to view and "disk assign" to change the disk pool
assignments.
