2.1.2.3 Activating Storage Server Cores and Disks in Oracle Exadata Database Machine Eighth Rack

The following procedure describes how to activate the storage server cores and disks.

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.

1. Log in as the root user on the first database server.

2. Activate the cores on the storage server group using the following command. The command uses the dcli utility, and runs the command as the celladmin user.

   # dcli -g cell_group -l celladmin cellcli -e "alter cell eighthRack=false"
   

3. Create the cell disks using the following command:

   # dcli -g cell_group -l celladmin cellcli -e  "create celldisk all"
   

4. Recreate the flash log using the following commands:

   # dcli -g cell_group -l celladmin cellcli -e  "drop flashlog all force"
   # dcli -g cell_group -l celladmin cellcli -e  "create flashlog all"
   

5. Expand the flash cache using the following command:

   # dcli -g cell_group -l celladmin cellcli -e  "alter flashcache all"
