The Confirm pop-up window appears. Attention When you select Yes in the Confirm pop-up window, information in the logical drive will be overwritten with zeros. All existing data is lost. 4. Select Yes to initialize the logical drive or drives; then, press Enter. The initialization process begins. You can see the progress in the Pct. Int. (percent initialized) column of the Logical Drive list. You can pause the initialization at any time by pressing Esc. Press Esc to stop the initialization and return to the previous menu. Press Enter to continue initializing the drive. Note You do not need to synchronize RAID level 0 or 1 logical drives before storing data. 5. You must synchronize all RAID level 5 logical drives before storing data. If you just initialized RAID level 5 logical drives, continue with "Synchronizing logical drives." Otherwise, continue with step 6. 6. If you have completed initializing the logical drives and do not have to synchronize any RAID level 5 logical drives, then you have completed the required steps for creating a ServeRAID configuration. 7. When the initialization process completes, back up the disk-array configuration information to diskette. See "Backing up the disk-array configuration" on page 126 for instructions. If you have not already done so, use the information provided in the ServerGuide package to install the operating system. Synchronizing logical drives: The purpose of synchronizing logical drives is to compute and, if necessary, write the parity data on the selected RAID level 5 logical drive. Synchronizing a RAID level 1 logical drive copies the data from the primary disk to the mirrored disk. RAID level 5 logical drives are automatically synchronized when you define them. You do not need to synchronize RAID level 0 or 1 logical drives before storing data. Also, the data scrubbing feature of the ServeRAID controller continuously reads all sections of RAID level 1 and RAID level 5 logical drives "in the background" while the system is running. If a defective sector is found, it is automatically repaired. As a result, you no longer have to synchronize RAID level 1 and RAID level 5 logical drives on a weekly basis. 110 Netfinity Server HMM
