To synchronize logical drives: 1. Select Initialize/Synchronize Log Drive from the Main Menu of the ServeRAID Configuration program; then, press Enter. 2. Select Synchronize Logical Drive from the next menu; then, press Enter. 3. Use the Up Arrow (↑) or Down Arrow (↓) key to highlight the logical drive that you want to synchronize; then, press the Spacebar to select the drive. Continue doing this until you have selected all of the drives that you want to synchronize; then, press Enter. 4. When the Confirm pop-up window appears, select Yes to synchronize the logical drive or drives; then, press Enter. The synchronization progress appears in the Pct. Syn. (percent synchronized) column of the Logical Drive list. Note Once the synchronization process begins, it cannot be interrupted. 5. Once you have completed synchronizing the logical drives, then you have completed the required steps for creating a ServeRAID configuration. 6. When the synchronization 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. Defining hot-spare drives: A hot-spare (HSP) drive is a hard disk drive that is defined for automatic use when a similar drive fails. The drive capacity of the HSP drive must be equal to or greater than the capacity of the drive being replaced. Notes: 1. If you want to have a hot-spare drive (HSP) or a standby hot-spare drive (SHS) and also assign RAID level 5 to one of the logical drives, you must have at least four hard disk drives. 2. In the event of a drive failure in an array that contains a logical drive assigned RAID level 0, the ServeRAID controller will not activate a hot-spare drive. You can use the Create/Delete/Copy/Log menu to define a RDY drive as a hot-spare drive. Or, you can change the state of a SBY, DHS, SHS, or RDY drive to HSP (see "Changing device states" on page 116). Netfinity 5500 - Type 8660 111
