## Enabling and disabling read-ahead cache mode

(Startable-CD mode only.)

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.

Note: You can override Adaptive read-ahead, but not through the ServeRAID Manager. Instead, use the IPSSEND command-line program. This program comes with the device option and is on the IBM ServeRAID Support CD.

1. Click a controller from the Main Tree.
2. Click Actions --> Enable/Disable read-ahead cache mode.
