following command; # mkfs /dev/TdZ1 (where T is the type of drive, s for SCSI or h for IDE; and Z is the letter of the drive you are booting; ex: dka0=sda, dqa0=hda)

20. The device is now ready to be mounted by the OS.

Reusing a previously installed hard drive

In some rare cases, you may find yourself needing to install onto a disk drive that has previously been installed to. It is important that you re-create the boot records on the drive. If you followed the rest of the instructions in this manual, you will have allocated the first three sectors of the drive for this purpose. Assuming that is the case, you can destroy the contents of those sectors prior to installing, using this command:

dd if=/dev/zero of=/dev/TdZ count=2 bs=512

where T is the type of drive, s for SCSI or h for IDE; and Z is the letter of the drive you are using; ex: dka0=sda, dqa0=hda.

TLZ07 and TLZ09 Errata

Problems have been observed when trying to install to systems that have TLZ07 and TLZ09 tape devices installed. Specifically, when booting from the floppy, the system will hang during the SCSI probe phase of the boot process. The suggested work around is to power down the system, remove the power plug from the tape device, and then repower and boot the system. After the system has been installed, you can reconnect the tape device.
