Removal and Replacement Procedures - Stripe Size-changes the stripe size. This field applies only to RAID 0 arrays. The default stripe size is 64 KB. IMPORTANT: RAID configurations do not support a stripe size less than 32 KB. You cannot change the stripe size of an array that has been configured already. - Drive Size-displays the size of the array and cannot be edited. If the array type is stripe, then the drive size is the total of all the drives selected. When mirrored, the drive size is shown by an individual drive. - Build Array-rebuilds the array using a spare drive. When Build Array starts, the utility prompts the user to select the target drive before rebuilding the array. This option applies only to RAID 1 and RAID 0+1 arrays. - Initialize Array-clears the configuration information from drives attached to the integrated ATA controller. • Delete Array (the F5 key)-deletes a currently configured array. • Restore Old Configuration (the F6 key)-restores the configuration that existed before you entered the utility. • Edit Options (the F7 key)-edits the physical drive option status boxes located in the top right corner of the Physical Drive Information window. The options are as follows: - WC-OFF-enables or disables write cache. CAUTION: Enabling write cache may cause data loss or corruption during an unexpected loss of power. - DMA-ON-enables or disables Direct Memory Access (DMA) transfers, in which data is transferred directly from the memory to the hard drive without microproccesor intervention. Pressing the F7 key enables or disables these options. Press the F7 key, move the cursor to the desired box, and then press the spacebar to select the option. When enabled, the option status boxes change from red to green. • Save and Exit (the F10 key)-saves the configuration and exits the utility. To exit the utility without saving the configuration or any changes, press the Esc key. Respond appropriately to the subsequent message boxes requiring confirmation.
