 Back up configuration to diskette
 Restore configuration to diskette
 Change the write policy
 Change the RAID parameters
 Format a drive
 Obtain drive status

Attention notices appear throughout this section to alert you about
potential loss of data. Similar warning messages appear on the

answering yes to the confirmation requests.
Backing Up Your Disk-Array Configuration
The ServeRAID adapter maintains a record of the disk-array
configuration information in its nonvolatile RAM (NVRAM) and
electrically erasable programmable read-only memory (EEPROM)
module. The disk-array configuration is vital information. To protect
this information, back up the information to diskette as soon as you
have completed your tasks.
To back up the disk-array configuration information to diskette:
Note: You need a blank, formatted, 3.5-inch diskette.
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 86).
3. Select Advanced Functions from the Main Menu.
4. Select Backup config. to diskette.
5. Remove the ServeRAID Configuration diskette from the drive
and insert the blank diskette.
6. Follow the instructions on the screen.
