ida -- Compaq EISA/PCI Integrated Drive Array (IDA) driver

Description

ida is the device driver for Compaq EISA/PCI Integrated Drive Array (IDA) controllers.

Refer to the Compatible Hardware Web Pages. to determine the support status of your host adapter, or contact your system supplier.

Configuring the ida driver

You can configure the ida driver using entries in /etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/ida. See mdevice(F) and sdevice(F). Changes to these files take effect once you relink the kernel using link_unix(ADM) and reboot the system.

Configure ida driver-specific characteristics by editing the /etc/conf/pack.d/ida/space.c file, which controls parameters such as the SCSI ID, the SCB handling mode, parity checking, and timeouts.

Boot time configuration

The ida driver supports the ida.nocheck bootstring(HW), which disables hardware checking by the driver. This allows Compaq IDA devices to be installed on non-Compaq platforms.

ioctl commands

The ida driver supports the ioctl(S) commands described on the hd(HW) manual page, as well as the ioctl commands for asynchronous I/O described on the aio(HW) manual page.

Diagnostics

The following error messages may be displayed on the console. See messages(M) for general information about kernel error messages, including a list of generic device driver errors.
