For all disk controller types, it is assumed that you have already physically installed the hard disk and booted the system.
This section describes how to install an additional IDE, EIDE, UDMA, ESDI, IDA, SCSI, or USB hard disk. If the disk is SCSI or USB, you must already have updated the system configuration files, as described in ``Configuring a SCSI hard disk'' and ``Configuring a USB hard disk''.
SCSI disks: Enter the host adapter type and number, the bus number, the disk controller ID, and the LUN of the disk.
USB disks: Enter the USB device ID and the LUN of the disk.
ST506, IDE, EIDE, UDMA, or ESDI-interface disks: Enter the number of the disk on the controller. If you are installing IDE, EIDE, or UDMA disks on ISA or EISA bus machines, you must also enter the number of the controller to which the disk is attached.
The mkdev hd script now runs the programs dkinit(ADM), fdisk(ADM), and divvy(ADM) in sequence to configure the hard disk for use.
dkinit is not run for SCSI disks. If you move a SCSI disk between machines or change the host adapter, you may need to run dparam(ADM) on the disk to change the geometry defined in the masterboot block. See ``Writing a new masterboot block'' for more information.
