3.7.4 Configuring Oracle Exadata Database Machine Eighth Rack Storage Servers After Rescue

For storage servers that are part of an Eighth Rack system, after a successful rescue, you must configure the cell using these steps.

In Oracle Exadata System Software release 11.2.3.3 and later, no extra steps are needed after cell rescue.

1. Copy the /opt/oracle.SupportTools/resourcecontrol utility from another storage server to the /opt/oracle.SupportTools/resourcecontrol directory on the recovered server.
2. Ensure proper permissions are set on the utility.

   # chmod 740 /opt/oracle.SupportTools/resourcecontrol
   

3. Verify the current configuration.

   # /opt/oracle.SupprtTools/resourcecontrol -show
   
   Validated hardware and OS. Proceed.
   Number of cores active: 6
   Number of harddisks active: 6
   Number of flashdisks active: 8
   

   For an Eighth Rack configuration, the output depends on the hardware model:

   • X3 storage server: 6 active CPU, 6 hard disks, and 8 flash disks should be enabled
   • X4 storage server: 6 active CPU cores, 6 hard disks, and 8 flash disks should be enabled
   • X5 HC storage server: 8 active CPU cores, 6 hard disks, and 2 flash disks should be enabled
   • X5 EF storage server: 8 active CPU cores and 4 flash disks should be enabled
   • X6 HC storage server: 10 active CPU cores, 6 hard disks, and 2 flash disks should be enabled
   • X6 EF storage server: 10 active CPU cores and 4 flash disks should be enabled
   • X7 HC storage server: 10 active CPU cores, 6 hard disks, and 2 flash disks should be enabled
   • X7 EF storage server: 10 active CPU cores and 4 flash disks should be enabled
   • X8 HC storage server: 16 active CPU cores, 6 hard disks, and 2 flash disks should be enabled
   • X8 EF storage server: 16 active CPU cores and 4 flash disks should be enabled
4. If the configuration shows all the cores and disks enabled, then enable the Eighth Rack configuration.
