2.1.2.4 Creating Additional Grid Disks in Oracle Exadata Database Machine Eighth Rack

Additional grid disk creation must follow a specific order to ensure the proper offset.

Note:

This procedure applies only to the original storage servers in the following Oracle Exadata Database Machine Eighth Rack models: X4-2, X5-2, and X6-2 with Extreme Flash (EF) storage servers.

This procedure does not apply where storage server hardware resources are expanded by adding more storage servers.

The order of grid disk creation must follow the same sequence that was used during the initial grid disk creation process. For a standard deployment using Oracle Exadata Deployment Assistant (OEDA), the order is DATA, RECO, and DBFS_DG (if present). Create all DATA grid disks first, followed by the RECO grid disks, and then the DBFS_DG grid disks (if present).

The following procedure describes how to create the grid disks:

Note:

The commands shown in this procedure use the standard deployment grid disk prefix names of DATA, RECO, and DBFS_DG. The sizes being checked are on cell disk 02. Cell disk 02 is used because the disk layout for cell disks 00 and 01 are different from the other cell disks in the server.

1. Check the size of the grid disks using the following commands. Each cell should return the same size for the grid disks starting with the same grid disk prefix.

   # dcli -g cell_group -l celladmin cellcli -e    \
   "list griddisk attributes name, size where name like \'DATA.*_02_.*\'"
   
   # dcli -g cell_group -l celladmin cellcli -e    \
   "list griddisk attributes name, size where name like \'RECO.*_02_.*\'"
   
   # dcli -g cell_group -l celladmin cellcli -e    \
   "list griddisk attributes name, size where name like \'DBFS_DG.*_02_.*\'" 
   

   The sizes shown are used during grid disk creation.

2. Create the grid disks for the disk groups using the sizes shown in step 1. The following table shows the commands to create the grid disks based on rack type and disk group.
