Return the HBA Cache Settings to Default Values in Legacy BIOS Boot Mode

After you have installed VMware ESXi, you must return the Oracle Storage 12 Gb/s SAS PCIe RAID HBA (host bus adapter) Internal cache settings to their default values. Reverting to the default values ensures that the server is operating efficiently.

1. Access the host console.

   For instructions, see Accessing the Host Console.

2. Power on or reset the server.

   For example, to reset the server, do one of the following:

   • From the local server, press the Power button on the front panel of the server (for approximately 1 second) to power off the server, and then press the Power button again to power on the server.

   • From the Oracle ILOM web interface, select Host Management → Power Control, and then select Reset from the Select Action list box.

   • From the Oracle ILOM command-line interface, type reset /System.

   The server begins the boot process, and the BIOS screen appears.
