IBM RS/6000 44P manual Flash SK-NET Fddi Firmware, Format Media

Flash SK-NET FDDI Firmware

This task allows the Flash firmware on the SysKonnect SK-NET FDDI adapter to be updated.

Format Media

This task allows the selection of diskettes, hardfiles, or optical media to be formatted. Each selection is described below.

Hardfile Attached to SCSI Adapter (non-RAID)

vHardfile Format

Writes all of the disk. The pattern written on the disk is device-dependent; that is, some drives might write all 0s, while some might write hexadecimal number 5F.

±Resource Selection List (choice of floppy drive or hard drive)

±If floppy (fd0):

-Diskette Media Service Aid

-Choose type of diskette to format

-Formatting occurs

±If Hard drive (hdisk0)

-Format Media Task

-Format and Certify Disk

-Format without Certify

-Erase Disk

vHardfile Format and Certify

Performs the same function as hard file Format. After the format is completed, certify runs. This certify reassigns all bad blocks that are encountered.

vHardfile Erase Disk

This option can be used to overwrite (remove) all data currently stored in user-accessible blocks of the disk. The Erase Disk option writes one or more patterns to the disk. An additional option allows data in a selectable block to be read and displayed on the system console.

To use the Erase Disk option, specify the number (0-3) of patterns to be written. Select the patterns to be written; the patterns are written serially. That is, the first pattern is written to all blocks. Then the next pattern is written to all blocks, overlaying the previous pattern. A random pattern is written by selecting the Write random pattern? option.

Note: The Erase Disk service aid has not been certified as meeting the Department of Defense or any other organizations' security guidelines.

If the data on the drive is to be overwritten, use the following steps:

1.Use the Erase Disk selection to overwrite the data on the drive.

2.Run a format without certify.

3.Run a second pass of the Erase Disk selection.
