9.7.2 Creating an ASM Disk Group for the Sparse Grid Disks

After you have created the sparse grid disks, you create an ASM disk group to enable those disks to be accessible to a database on the cluster. To create a disk group, log in to an ASM instance using SQL*Plus as sysasm and run a command similar to the following:

SQL> create diskgroup SPARSE high redundancy disk 'o/*/SPARSE_*' attribute
'compatible.asm'='12.1.0.2', 
'compatible.rdbms'='12.1.0.2', 
'au_size'='4M', 
'cell.smart_scan_capable'='true', 
'cell.sparse_dg'='allsparse', 
'appliance.mode' = 'TRUE';

compatible.asm must be set to 12.1.0.2 or higher.

compatible.rdbms must be set to 12.1.0.2 or higher.

cell.sparse_dg must be set to "allsparse". This identifies the disk group to ASM as being made up of sparse grid disks.

appliance.mode must be set to true.
