Hi everyone,
We are trying to remove all partitions on our netapp AFF300, to reinstall it with one root partition and 2 data partitions (as it was when we received it).
Right now we are in a configuration with one root partition and one data partition.
We followed this netapp documentation https://library.netapp.com/ecmdocs/ECMP1636022/html/GUID-CFB9643B-36DB-4F31-95D4-29EDE648807D.html
unsuccessfully.
We are strugulling with the command disk unpartition 0d.01.21. Here is the error :
Disk 0d.01.21 must not have file system partitions. All partitions must be spare
Do not proceed with unpartition if disk has file system partitions. Abort unpartition (y/n)? n
Jan 11 13:28:50 [localhost:raid.unpartition.disk.fail:notice]: Disk unpartition failed on Disk 0d.01.21 Shelf 1 Bay 21 [NETAPP X371_S163A960ATE NA50] S/N [S396NA0HA06398], error CR_DISK_WRONG_STATE, additional error info ().
disk unpartition: 0d.01.21 has partitions that are not spare.
We can't find any solution on google, so any help would be much appreciated 
Regards
Jean-Pascal
