We have a system that is configured as follows:
FAS8020, DataONTAP : 8.3.2 P2 HDD size 2.0TB SATA
Name Node Type used% Available Used Total Volume Count Disk Count
System_A_aggr01 System_A Std 2 51.38TB 1.01TB 52.39TB 2 42
System_A_root System_A Std 32 2.83TB 1.32TB 4.15TB 1 5
System_B_aggr01 System_B Std 2 51.38TB 1.01TB 52.39TB 2 42
System_B_root System_B Std 32 2.83TB 1.32TB 4.15TB 1 5
Only 1 spare drive per system. All HDD used.
Client has decided they want to increase the number of spares by reducing the root aggregate from 5 to 3 HDD. There is one SVM defined and although there is only a small amount of data on it they would prefer to preserve that if possible.
What is the best way to achieve this? Worse case is trashing the system and rebuild it, but we'd prefer not to if we can avoid it
Is it possible to drop disks out of an aggregate providing there is sufficent remaining capacity to hold the data on the reduced number of disks?
My experience of DataONTAP is very limited so any guidance will be very much appreciated.
Many thanks
Chris
