Adding hard disks

Supported hard disk configurations

Many hard disks can be used with SCO OpenServer systems. Most IDE, EIDE, UDMA, ESDI, Compaq IDA, SCSI, and USB disk controllers are supported.

On ISA, EISA, MCA, and PCI bus machines, the wd device driver is used with disks which present a WD1010 or ST506, IDE, EIDE, and UDMA interface. The Sdsk device driver is used with all SCSI disks, as well as USB disks.

On MCA bus machines, the esdi device driver is used with ESDI disks. The st506 device driver is used with ESDI disks which are configured to present an ST506 interface.

Refer to the SCO Certified and Compatible Hardware web page (CHWP) for a listing of supported disk drives.


NOTE: The MAX_DISK dynamic kernel parameter limits the number of disks that are supported by the kernel. You may need to use the Hardware/Kernel Manager or the configure(ADM) command to change its value if you previously set MAX_DISK to limit the maximum number of disks. A value of 0 allows the kernel to support more disks dynamically.
