Hi guys.
We have a cabin with Ontap 9.7P6, the storage has 12 disks and shelf with 30 disk, the configuration:
aggr0_controller1: disk type SHARED (1,3,5,7,9 + 11 HS) with ADP (partition root and data)
aggr0_controller2: disk type SHARED (0,2,4,6,10 + 12 HS) with ADP (partition root and data)
The remaining 30 disk are type SPARE, and no partitioned.
I want the aggr0 of both controllers to use fewer disks, instead of 6 disks, only 4 disks in RAID DP each controller, and the 4 disks that I recover, I want to use them for the other 30 type spare disks, so I will have 34 disks for make 2 aggr of 16 disk
I have migrated the root volumes of aggr0, being as follows:
agg0_controller1 --> disk 1,3,5,7 RAID DP
agg0_controller2 --> disk 0,2,4,8 RAID DP
but now disks 8,9,10 and 11, are still SHARED type and have root and data partitions, and when I want to create 2 aggregates for data with the other 30 disks it doesn't let me select them. I have tried to change the type from SHARED to SPARED of those 4 discs, but have not succeeded.
What I have highlighted is the following, I have restarted the controller 2, and I have entered the Control C menu, I have selected the ADP 9 option.
I have used option 9a to delete owner and partitions, then I have selected option 9b, since I want the aggr0 root volume to be a partitioned disk, but not the rest of the disks, since I want them without partitions to add different data .
Once this is done, I have restarted the controller, I have executed boot_ontap, but it no longer starts, it always restarts and automatically enters the Control C menu and does not exit from there.
It does not automatically install the ontap on those 4 disks that I want.
Then I have entered Control C in option 5 Maintenance, and I have put the owner the controller 2 of those 4 disks (0,2,4,6) I have rebooted, but it does not install.
And finally, I have returned to option 5 maintenance, and then to LOADER, and there I have executed boot_recovery, it seems that it wants to start the Ontap installation, but it reselects the disks that it wants (0,2,4 , 6,8, + 10 HS) and not the ones I want, but at the end it shows me an error: it tells me that it has not managed to create the root volume.
Currently I have controller 2 that if I restart it, it does not have an aggr root volume and it does not start, it stops in the Controller C menu.
What would be the procedure to install the ontap on controller 1 with the ADP disks (disk 1,3,5,7 RAID DP) controller2 disks ADP (disk 0,2,4,6 RAID DP) and then the rest of the disks from 8 to 42 are of type SPARE without having partitions to create 2 aggregates one for each controller and store the data?
Many thanks,
