To protect this information, back up the information to diskette as soon as you complete your tasks. The ServeRAID controller maintains a record of the disk-array configuration information in its NVRAM, in an electrically erasable programmable read-only memory (EEPROM) module, and on each ONL and RBL drive. Attention: Dynamic changes in the configuration of your disk arrays can occur due to hot-spare drive replacement or other drive maintenance activity. It is important that you back up the disk-array configuration information frequently, to keep the backup information on the diskette current. You need a blank, 3.5-inch, 2 MB, formatted diskette to create a backup copy. To back up the disk-array configuration information: 1. Label a blank diskette "Disk-Array Configuration Backup" and date it. 2. Start the ServeRAID Configuration program (see "Starting the ServeRAID Configuration Program" on page 77). 3. Select Advanced Functions from the Main Menu; then, press Enter. 4. Select Backup IPS ServeRAID Config from the next menu; then, press Enter. (The disk-array configuration is also known as the IBM ServeRAID (IPS) configuration.) 5. Insert the blank Disk-Array Configuration Backup diskette into the diskette drive. 6. A pop-up window appears with a default file name of CONFIG; change the file name by typing over the default; then, press Enter. The Backup program assigns a file-name extension of .ips. 7. The Confirm pop-up window appears. Select Yes to confirm that you want to copy the file to the backup diskette, or select No to return to the previous menu; then press Enter. 8. Remove the backup diskette from the drive and store it in a safe place. 9. Press Esc to return to the Main Menu. 126 Netfinity Server HMM
