Hewlett-Packard NetRAID-4M Controller Installation Guide s Enable Disconnection -This option determines whether the SCSI channel allows the SCSI device to disconnect from the SCSI channel (sometimes called Disconnect/Reconnect or Reselection). This option should be enabled for maximum performance. s Initiate Wide Negotiation -This option determines whether the SCSI channel attempts 16-bit data transfer instead of 8-bit data transfer. The effective data transfer rate is doubled when 16-bit data transfer is used. Using the Disk Utilities To access the disk utilities, select the Disk Utilities option from the main menu that appears after entering the Configuration Utility and selecting the desired HP NetRAID-4M. Select the desired bus and press Enter. Once the option is selected, a list of all SCSI IDs and the devices assigned to each ID is displayed. When you select a specific ID and device, a small menu appears, displaying the options Format Disk and Verify Disk Media. s Format Disk-This utility allows you to perform a low-level format on a hard disk drive. Each hard disk drive must be lowlevel formatted before you can use your operating system's partitioning and file preparation utilities, such as MS-DOS Fdisk and Format. Most SCSI disk devices are preformatted at the factory and do not need to be formatted again. The Format Disk utility is compatible with the vast majority of SCSI disk drives. ! Caution: A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. You cannot abort a low-level format once it is started. Note: The controller should not be powered-off or rebooted during a disk format. Doing so may render the disk unusable until the format is manually restarted and completed. A-6
