Adding System Drives
The recommended method for creating UNIX file systems on System Drives
is through the SCO UNIX mkdev hd command. Follow the instructions in the
SCO UNIX documentation for adding a hard disk.
Mylex Disk Array Controllers are mapped differently under SCO UNIX than
under the Mylex Disk Array Controller Configuration Utility. It is necessary
to use the target ID and the LUN number to identify each system drive being
created for SCO UNIX.
The following table shows the relationships of SCO UNIX target IDs and
LUNs to System Drive numbers as defined under the Mylex Disk Array
Controller Configuration Utility. For example, for System Drive number 20,
enter 4 for the target ID and 3 as the LUN (shaded areas in Table 5-1).

Note
The bus number is always zero.
