Adding System Drives

PCI Disk Array Controller Drivers Manual

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).

☛

The bus number is always zero.
