Controller Enabling and disabling read-ahead cache mode

Use this action to set the read-ahead cache mode to Enabled or Disabled. If the read-ahead cache mode is set to Adaptive, you cannot use this action.

 You can override the Adaptive setting, but not through the ServeRAID Manager. Instead, use the IPSSEND command-line program included on the IBM ServeRAID Support CD.

  1. In the Logical devices view, click (array).

  2. Right-click Configure read cache enabled or disabled.

  3. Click Yes to confirm.
