The X3-4 Exalytics Machine comprises 6 hard drives, each having a capacity of 900 GB.Two drives are configured as RAID1 and four drives are configured as RAID5. To optimize the use of the disk space, you must reconfigure the RAID1 and RAID5 configurations on the Exalytics Machine. Reconfigure RAID1 so that it consists of two virtual drives of 100 GB and 657 GB, and RAID5 consists of the remaining drives.
To reconfigure existing RAID configurations on the X3-4 Exalytics Machine:
The "Copyright LSI Logic Corporation" displays during the restart sequence when it is possible to enter the RAID CLI. Observe the screen carefully as the message displays for a very short time. This avoids restarting the machine again.
