Syntax

ALTER DISKGROUPS 
   DATASPLIT=data_split_percent 
   RECOSPLIT=reco_split_percent
   DATAREDUNDANCY=data_redundancy_level
   RECOREDUNDANCY=reco_redundancy_level 
   SPLITDISK=percent_of_cell_disk
WHERE
   DATADG=data_diskgroup
   RECODG=reco_diskgroup 
   { CLUSTERNAME=cluster_name | 
     CLUSTERNUMBER=cluster_number | 
     CLUSTERID=cluster_id }

Arguments

You can modify the following sizing attributes of the DATA and RECO Oracle ASM disk groups:

• DATASPLIT : Specifies a percentage of the Oracle ASM volume allocated to the DATA disk group. The sum of DATASPLIT and RECOSPLIT cannot exceed 100.

• RECOSPLIT : Specifies a percentage of the Oracle ASM volume allocated to the RECO disk group. The sum of DATASPLIT and RECOSPLIT cannot exceed 100.

• DATAREDUNDANCY : Specifies the redundancy level for the DATA disk group. The accepted values are NORMAL or HIGH.

• RECOREDUNDANCY : Specifies the redundancy level for the RECO disk group. The accepted values are NORMAL or HIGH.

• SPLITDISK : Specifies the percentage of the cell disk to allocate to the DATA and RECO disk groups. The specified value must be an integer between 1 and 100.

The following arguments are available in the WHERE clause:

• DATADG : Specifies the name of the DATA disk group in the cluster

• RECODG : Specifies the name of the RECO disk group in the cluster

• CLUSTERNUMBER : Specifies the cluster number in the es.xml, starting at 1

• CLUSTERNAME : Specifies the name of the cluster

• CLUSTERID : Specifies the es.xml ID of the cluster
