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
.
