v SCSI Disk Utilities Select this choice to view the SCSI IDs that are assigned to each device or to format a SCSI device. To use the utility program, select a drive from the list. Read the on-screen instructions carefully before making a selection. Note: If you press Ctrl+A before the selected drives are ready, an Unexpected SCSI Command Failure screen might appear. Restart the server and watch the SCSISelect messages as each drive starts. After the drive that you want to view or format starts, press Ctrl+A. v Format Disk Attention: The Low-Level Format program erases all data and programs. Select this choice to perform a low-level format on a hard disk drive. Depending on the hard disk drive capacity, the Low-Level Format program could take up to two hours. Use the Low-Level Format program: - When you are installing software that requires a low-level format. - When you get recurring messages from the diagnostic tests directing you to run the Low-Level Format program on the hard disk drive - As a last resort before replacing a failing hard disk drive Note: If the server has a PCI RAID adapter installed, refer to the RAID adapter documentation for instructions for performing low-level formats on hard disk drives attached to the adapter. To start the Low-Level Format program: 1. If the hard disk drive is working, make a backup copy of all the files and programs on the hard disk drive. (See the operating system information for instructions.) 2. Select Format Disk; then, follow the instructions on the screen. Note: Hard disk drives normally contain more tracks than their stated capacity (to allow for defective tracks). A message appears on the screen if the defect limit is reached. If this happens, replace the hard disk drive. 30 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual
